Global Warming US Cities Getting Warmer

[tiffcomp]

This is nothing but misinformation

Plenty things could happen

I could win the lotto, i never do

Thinking i could win the lotto should i spend the money now?

Well i could win the lotto so shouldn't i count on it happening? Of course not!!!

None of this is based on proven science.

It is all hypothetical.

Since when do we make disicions based on hypothetical scenarios.

We are better and smarter than this!

We need to look at the people who claim these things, and why they are claiming them.

[Catoni52]

Good video..... but the background music is very distracting when listening to a lecture.. Maybe leave voice level the same, and lower the music level until we can barely hear it. The music is too loud compared to the voices.

[davidcourardhauri1]

Nice work! Good curiosity. You have found what other scientists have found: warming in the United States has been very limited compared with other parts of the world over the time frame you are looking at. Most of the global warming is happening in polar regions, over Asia, Europe, and Africa, and over the Atlantic and Indian oceans (confirm on the GISS site). What worries me is that your commenters are acting as if this contradicts what scientists say--and that's not true. Scientists know this.

[wikeroy]

Well done! If only more people would seek the raw data and investigate, instead of flatly believe what idols, rock stars and the media says. Most of the time they have a hidden agenda.

[RichardRoy2]

That was brilliant. Interesting what kind of speculation can go to explaining the changes in the urban centres. Off the top of my head, I'd say building materials and/or practices, or the wastful use of energy that ends up heating the suroundings. Could be architectural design. Could be poor insulation. Reduction in vegetation in those areas? Enjoyed the presentation. Thanks.

[OceanDashTwo]

"Doesn't explain the change in ocean temperature"

It also doesn't explain the price of eggs. No one said it does - it simply *demonstrates* the difference in data sets recording the same parameter.

This analysis (done very well and in a scientific manner) should cause people to question anyone who states categorically that 'temperatures in the US are rising'.

It should promote individuals to dig a little deeper and take what any talking-head states as a fact with a dose of skepticism.

[welling8l4nk]

Doesn't explain the change in ocean temperature.

[dmiller185]

I have added this to my favorites list. So I feel fully justified in holding both you and your son responsible for providing the name of the background music you used for this video. If my implied demand is not met, I will haunt whatever house you live forever in the following way: when you use the fridge, I will blow cold air on you in a nearly uniform manner. Consider that before ignoring me.

[micahspicer1]

Can you send a copy of your data sets and graphs to me I would very much appreciate it.

[TheseData]

We are in process of analyzing over 600 rural sites across the US. It will take some time to do so. We are looking at sites with temperature readings from 1930 to 2009 (80 years). We do see a difference in sites near cities and those further away. There are regional differences. Some regions could be said to be warming, some neutral and some cooling. Overall the pattern is that temperatures were average or a little warmer until the 50's, then got colder, then got warmer. More later.

[TheseData]

1- you don't have "error bars" on curve fits. You have R2 values which are there. The R2 values are low and show the lack of significance.

2-we picked what sites we could find that met our criteria.

3-Our method was to look at sites within 100 km of each other (matched sites).

4-see 3

5-We do not make any global statements, only about the two populations compared.

[r31ncarnat3d]

@TheseData Good luck explaining stats to them... Most people who have never taken a stats class in their lives still subscribe to the "Correlation proves Causation" fallacy, let alone understand R^2 values or the explicit conclusions drawn from data analysis.

[mikey3k]

4. They completely ignore any rural areas further than 100km from cities, thus ensuring that any conclusions they reach cannot be used as any rebuttal of NASA's chart for the entire United States.

5. They don't address the fact that the USA is a region and hence is not the world.

[mikey3k]

So here's a few criticisms of this:

1. Error bars.

2. They do not reveal their method for choosing urban/rural temperature station pairs, hence it could easily be that they just picked those pairs that happen to support a preordained conclusion.

3. They only pick rural sites that are within 100km of urban sites and are thus unable to rule out the possibility of cities having a suppressive effect on temperatures in their surrounding rural areas.

[1noen1]

Denialst claims about "heat island effects" have been throughly debunked. Real Climate has the details.

[Finlandcitizen]

Indeed, Phil Jones actually made an peer-review paper about the Urban Heat Island effect on China and how he compensated for it.

How about that.

[regresseur]

Why don't you tell everyone what the difference would be, since you obviously would understand it?

[AnInquirer]

1. GISS adjusts data for various reasons. These adjustments add t increases thru time.

2. Local siting issues can cause rural temperatures to overstate increases regardless . E.g. HVAC exhaust didnt exist 50 years ago. Also new thermometers have cables that induce installations closer to the building.

3. Whether warming is caused by human-emitted CO2 or by land use changes makes a big difference in how we attack any problem.

[PonguigPeopinn]

I am now contacting my lawyer since this child obviously works for the oil companies such as BP who also support the UN for some reason.

[markiz2001]

this kid obviously works for the oil companies.

[jtalcott]

ed2see, I must assume that you are kidding. Obviously, the gathering of people does not cause temperatures to rise. Rather, the way we create the cities in which people gather involves building materials such as concrete that tend to trap heat during the day and radiate it during the night, leading to a higher average temperature readings at sites which have urbanized over the last 100 years. More concrete, more perceived temperature. Not, as people would like you to think, catastrophic AGW.

[ed2see]

Wow what a smart kid! So what I get from this data is that we should utilize all the land in America for population instead of grouping them into cities. If we spread out the population the heating will be more balanced. Sustainable development is wrong since it puts more people together into commune like living. I am glad that intellectual people like these two exist and hopefully more people use their intelligence and turn off the television.

[hatchedarea]

Good work you two! This is exactly science as the likes of Karl Popper and Immanuel Kant intended.

[EarthaKit2]

We can discern that you are a "front" for your father.

1-This information is fr NASA, liars, the government itself, wishing to impose all abuse laws on We, The People.

Geez, it's like asking a CRIMINAL whether he is guilty.

cont'd

[lonelyshag]

The urban temperature increase is due to all the concrete steel and asphalt surfaces in the cities such as roads, structures,asphalt. Airports ect. Ever look at an aspalt surface on a sunny day. You can actually see the heat or solar energy being produced...Solar energy could be the key or gateway to a better future for mankind.

[hcdragonfly]

If global warming is a global issue, then the temperatures in all urban and rural areas should've increased, I think, because the heat, unlike human beings, does not recognize boundaries.

[mij6112]

Karen says the raw data hasn't been changed. Where would one find this raw data? GISS is being sued right now for not releasing their raw data. I'll bet she doesn't even know where GISS gets their data from. She is in a state of denial.

[TheseData]

As was mentioned before, the US is really the only location that has enough temperature stations where one can find both urban and rural sites within a 100 km radius. There are possibly a few outside the US but hard to find. Also, you want sites that both go back at least 70 years with continuous reads. We were able to go back to before 1900 with the US sites. We are now analyzing US rural sites at least 50 km from urban sites. We hope to have over 500 done in a while.

[CanisLupusSeeUs]

Can some 6th grader please comment on this video so that we can say it has been "peer reviewed"?

[CanisLupusSeeUs]

Thank you, Peter. I'm, giving you an A+ for your work and propose an award be sent to you, a statue with a naked Emperor on it. Meanwhile, Al Gore should have his Nobel prise replaced with an Academy Award for his fanciful depiction of someone who had something worthwhile to tell the world.

[brownthundertx]

Awesome! Of course all of the ecotards will come here and say there is no heat island effect...but then why did CRU, GISS, NOAA, et al, change the raw data 12 times in the last 5 years.  No MWP...no LIA...what will they want us to believe next? 2+2=5? Great observations young man.

[KarenRei]

The raw data has not been changed.  Some of the process data has been changed as various sources of error have been identified and corrected (often due to discontinuities arising from different kinds of equipment being used), but only by very small amounts.

[nikcolman]

Congratulations on a fabulous presentation. Simple and to the point.

Don't be put off by people like Karen trying to muddy the waters by insinuating anyone with an opposing view "don't know what the F*** they're doing". That is the usual level these people sink to. Careful, as next you'll be a labelled a denier!

Follow your own research and come to your own conclusions and keep up the great work.

[TheseData]

Peter's Dad here. Remember, this is only a little illustrative video. It shows a comparison of two populations. As we explained, the US is really the only location that has enough sites for this type of comparison. We are currently looking at the US rural sites and it will take some time to finish the analysis.

[KarenRei]

No, the US is *not* the only location that has enough sites for this type of comparison. Regional trends are highly correlated for many hundreds to thousands of miles. If you had actually ever read any of the research on the subject, you would be aware of this.

[mannycanada]

Thank you Peter & dad. I would love to get the graphs as hi res pictures. Please post this presentation as a PowerPoint (or equivalent). Also, please post the raw data so that everyone can redo your graphs -- especially those who criticize you. Thanks a million for your great work.

[owlnebula]

Excellent work Peter, we need more youth taking an interest in Science. You researched the subject, made observations, checked your data and results, and gave a solid presentation.

Your work has been hijacked in the AGW controversy. I encourage you to learn more, and see how it applies. People have passion about AGW, much driven by fear. Fear of what we may be doing to our environment, fear of change, fear of others intentions. Don't allow rude people to discourage you, keep to the high ground.

[Atom299]

Yes definitely Global warming is "Mann Made" this could be a powerful slogan to help wake people up.

Let's get our T-shirts and posters made fast

[RealOldOne2]

Doug1943

You're joking right? Not science if you dont share data.

Wrong with the data? Urban stations had a rising temp while the rural ones had no change in temp over the past 100 yrs. Do you dispute that?

Interesting though that their chart of Hemlock (@1:54) shows a 1978 temp of about 6.6 deg, while the current GISS data shows 7.6

Hmmm,  1978 avg temp just got 1 deg warmer since July of 2008

I guess there is warming. And since nature couldn't have caused it, must be Mann- er, man-made

[KarenRei]

Thanks for a great example of why people who don't know what the F*** they're doing shouldn't be getting involved. The datasets aren't just made of averaged data from all stations. The heat island effect is automatically detrended by widely studied algorithms. The results have been verified as well by, for example, comparing urban vs. rural stations on calm vs. windy days (wind reduces the heat island effect).

Could you all get a life, please?

[RealOldOne2]

KarenRei,

Maam, take a deep breath. Now, instead of getting your panties tied in a knot, emotionally spewing vulgarities and blowing smoke about wind, just address the issues.

Pierres: If the HI effect is detrended, then please explain THE DATA. Why did urban temps go up while nearby rurals didn't? Did he misuse the GISS data?

Mine: Did the 1978 Hemlock GISS temp recently go up or not? If it did, why?

Could you just answer the questions, please?

Thank you kindly.

RealOldOne2,P.E.(Prof Engr)

[KarenRei]

The *raw* data isn't detrended. The *processed* data is. TheseData is looking at the raw data. So yes, he absolutely did misuse it.

Also, as though there haven't been over a dozen peer-reviewed studies looking into this. I know YouTube takes preference over peer review in most people's world, but in science, Peer Review wins.

[RealOldOne2]

No misuse! He said he was using *combined* dataset. GISS says that is combining multiple *raw GHCN+USHCN corrected* records at the same station, which is the correct dataset to show long term change of a single station without any interference with neighboring stations. He never claimed to be using *processed* data.

He made 3 only conclusions:

1)urban site temps higher than nearby rural

2)diff between urban & rural site temps is increasing

3)rural temps not increasing

Any of his concl wrong? No!

[KarenRei]

Want more errors while we're at it? We're talking about global climate change, but TheseData is only looking at the US. The US ha actually seen relatively little warming compared with the rest of the world (most warming is concentrated in the arctic). The fact that the US has the highest concentration of monitoring stations is utterly irrelevant to what the different trends worldwide are.

[RealOldOne2]

Whoa! No more errors here! Youre just raising a smokescreen.

Neither Pierre, his dad, nor I mentioned ANYTHING about *GLOBAL* climate change.

He made 3 simple conclusions from looking at some official GISS measured site data.

Are you denying that his conclusions are true? Speak up. Were waiting.

I sense youre a little defensive, reading more into simple statements than what is actually said. Climategate got you worried? Youre sticking your fingers in the dike where there are no holes.

[KarenRei]

"Neither Pierre, his dad, nor I mentioned ANYTHING about *GLOBAL* climate change."

Then what was the point of this? "Here's some non-conclusions about something other than global warming?"

[RealOldOne2]

Karen-

Pierre stated the point in the first 10 sec-'to see if urban temp data are warmer than rural data'

He designed an experiment, collected & analyzed data and drew 3 concl, not non-concl.

Based on his data, why do you refuse to acknowledge his concl? Because they go against your beliefs? That's religion, not science.

Either point out flaws in his data or methods, or acknowledge the facts & concl. he presents, THEN think critically & ask good questions. I can think of one you should ask.

[KarenRei]

I already pointed out the error that his data isn't being detrended, discontinuities detected and eliminated, bad stations detected and eliminated, and so forth. It's a very complex process that has undergone peer-review, and he's doing none of it. And furthermore, how many times do I have to point out that this is insinuating a conclusion (global warming is just a heat island effect) that even if his work wasn't full of errors, it wouldn't support (due to the US being slower-warming)?

[RealOldOne2]

Karen

Are you saying that the GISS temp data is garbage (ie. has discontinuities, bad stations, etc) and cant be used for any analysis?

If youre not saying that, then tell Pierre which GISS data set he should use.

Also tell him if any of the 56 stations that he used are BAD ones.

Dont just tell Pierre that hes doing it all wrong.

Help this fine young man do his experiment PROPERLY.

Im going to try to replicate his experiment so that it can be *peer-reviewed*.

Be our technical advisor.

[CanisLupusSeeUs]

Give up, Karen. There is always 2012 you can amuse yourself with, plus the regular supply of doomsday Hollywood movies. Then in 2029 there is a meteorite due to come close to earth. If all that fails to satisfy your appetite for disasters and rabbiting on like Al Gore, then join some cult who believes the end is nigh. AGW has had its day. It was fun while it lasted, but its time to learn a new script.

[reaperjd]

Don't forget 2012 all the planets align, should be fun! ;)

[syinreno]

KarenRei,

Your an idiot.

[TheseData]

We used the "combined data" for the site and we collected the data in the spring of 2008. I have looked at a couple of the sites and the data are now different. I know that JohnV who comments on the Wattsupwiththat site has done a comparison and has found differences. Thank you for watching the video

[RealOldOne2]

Thanks ! Great job.

[TheWyane]

This is rubbish. Where are the urban areas in the Arctic? The oceans?

[jbtascam]

Rubbish? That's hardly a scientific debunking. Disprove the analysis with something like facts, or data, or reasons why the assumptions are in error - not with your own dogmatic statements of faith and straw men.

[pontala]

hahaha you so funny maybe climegate will explain it for you! google climate gate and you will see that global warming is a political tool to tax and control people! the same bankers and elites that are financing socialism are behind carbon tax scam.

[Doug1943]

What is the Goddard institute doing, allowing raw data to be released into the hands of non-scientists? This was totally irresponsible on their part. This data should not be open to people who will just try to find something wrong with it.

[goflyfalco]

Interesting clip, spoiled by the intrusive, distracting "Music". I found it difficult to absorb the content because of this.

"Lose the music!"

[juuel321]

great video good job =) So global warming is not happening in New Zealand, not in USA, not in FInland, where is it really happening then? North pole seems to be one of the few places warming right now. true?

[TheseData]

There are no conclusions presented in the video concerning global warming. It is a comparison between two populations of sites, one shows warming and one does not appear to show warming.

[Lsdfunk]

AGH!

Urban Warming!

We're all going to die!

Unless... we all give away our rights & money! Oh god, it's our only hope!

xD

Bye bye AGW. :(

Now, all we have to do is turn off the tv, & let our government officials know; the jig is up.

P.S I know there were no conclusions drawn in the video. But, from the content I have drawn my own - which seem fairly evident to me.

[randallhilton]

I love the openess of science this way. Question: do you have the ability to perform the same comparisson using all available rural sites with a given span of history and compare it to all available urban sites with the same span? It would be interesting to see how that compares to your results.

[yt555555]

As the population density increases in an area the ratio of trees to buildings decreases. Block sizes get smaller and the gardens get too small for large trees. As nature gets replaced by bricks, tiles and bitumen air temperatures rise. This effect cannot be accurately quantified.

The theory of green house gases causing global warming is well over 100 yrs old and scientists have been looking for this warming for quite some time. Looks like they have found it in their own backyard.

[yt555555]

Excelent video. I find it interesting how people interpret it differently. It states no conlcusions.

Does it use raw data or homogenised data?

Either way it shows that temperature has not increased in rural areas over the last 100 yrs.

Currently the scientific consensus is that we are warming at 1 degree per century and that this has been proven.

If that proof relies on the same thermometers featured in this video then it hasn't been proven to me.

Seek and ye shall find.

[slowtyper5]

LOL!!!  Al Gore is NOT "Smarter Than A 6th Grader".

[jinnah1313]

Great video. Data source and reasons for their choice and the method of analysis given. Conclusions don't stray from the analysis done.

This is good research from a careful researcher. I give my congratulations and respect to you.

Please note that the video doesn't make ANY claims about global warming (or not). Those linkages are in the heads of the commenters. Don't criticise the author for your fuzzy thinking.

[fredontube]

You didn't hide the rise, did you?

(just kidding)

[DaveDoggOwns]

Unless its peer reviewed, his video won't do a thing to debunk global warming.

[pondman27]

STUFF the peer review process. Its messed up on a host of areas. I mean no respect to the people that work with the system, but we KNOW the ways various psuedoscientific technologies have been bending the rules.

Sure the truth is out there, but reliance on journals that have close links through advertising! well it speaks for itself.

[DaveDoggOwns]

Stuff the peer review process? So you're saying we shouldn't subject new scientific theories to the scrutiny of others?

[pondman27]

The existing scientific peer review process has been severly undermined by the control of research direction by financial & corporate interests that covertly steer the direction.

Many technologies exist that hold enormous potential for humanity, but the existing status quo, has actively supressed anything that does not conform to the agenda. WE need a new forum, for scientists, one that is not subjected to the manipulations of political agendas or corporate interests.

[DaveDoggOwns]

"covertly steer the direction"....nice way to not have to provide any proof of bias. If something is highly beneficial for humanity and will make a lot of money then why wouldn't "financial & corporate interests" not want to research into it?

And all those technologies (cold fusion, zero point energy, etc) have been poven to be false.

[pondman27]

Oh Boy, are you in for a surprise. You have n't worked it out yet.

Just ask one question.... In what primary direction has the research establishment spent most of our tax on?

Purchasing technology for multiple forms of warfare & security. Every aspect of the subjects accused of others, have been inflicted by these wars. These wars are now declared on humanity through population control that is being demanded by parties to Copenhagen! Which sectors of humanity will benefit?

[DaveDoggOwns]

K then get rid of the taxes and subsidies and not the peer review system. What you're complaining about is the problem with the state, Not a problem with peer review.

[langier2]

Rush Limbaugh should hire you as an "expert" on the climage! Great job!

[dragonsjaws]

CBS, NBC, ABC, CNN, can't seem to get their journalistic act together and ask basic questions anymore. This is fundamental information. Most of the nation is rural. Most of the nation is not warming.

This is why newspapers are losing readers, cable TV news is losing viewers. It's because ordinary citizens posting on YouTube are doing better journalism than the "pros."

Would someone send Katie Couric a link to this page? Haha.

Good job, guys. I hope this gets 100K hits.

[IridescentEye]

Good to see someone teaching their children critical analysis and logic.

This video is a credit to both man and boy ..... 5 stars.

[NonInflatable]

Peter - you may be interested to know that the people at the Armagh Observatory in Northern Ireland have been tracking temperature since Queen Victoria was in her prime (1865).

Their data is available on line in the form of two neat charts.

What this demonstrates is that over the past 135 years there has been NO demonstrable change in the temperature of Northern Ireland.

The text box will not permit a link, but check out Armagh Observatory on Google.

[NonInflatable]

Wonderful piece of work, Peter. Your dad must be proud of you.

Clearly, putting a temperature recording station in an urban site is likely to yield an upward trend that is not representative of the true situation.

Do you know how many of the US temperature stations are located in urban sites? What percentage of the whole does this represent?

This is of critical importance and I would very much like to know the answer.

[Johnincnet]

Peter: Amazing job! You have a great future in science! I hope you always go into a topic with this kind of enthusiasm and methodology. Your attention to detail is awesome. Keep it up!

[randallhilton]

Excellent vid, Peter!

Question: Are you able to do a cross check to determine the percentage of urban sites vs. rural sites used in the CRU and others models? This could be very significant.

By the way. . . thanks for demonstrating science the way it should be done. Phil Jones should come to your seminar. ;o)

[The314Stalker]

What This study does show is; we need to think about how we design developments and urban areas so they aren't highly concentrated groups of buildings without trees. It is widely accepted that trees contribute to cooling the earth, this is pretty basic science.

[The314Stalker]

Reality check here. The data showed that rural areas aren't cooling. This is well known and not news at all. One of the criteria for this study was the readings had to be taken from the same place throughout the study. Which shoots down the idea it is just an anomaly caused by "urban heat sinks".

[greasyjoe90]

You Two should be in Copenhagen, a six minute presentation and they could all go home.

You've done well, you should be proud of yourselves.

[laroquois]

Good for you Peter and his Dad.

Simple and effective presentation.

[bitbutter]

Very interesting. Thanks!

[aronswritingdeskyt]

Very well done!

[WhoSaidThat32963]

Forget Cap and Trade. For this and a score of other reasons, we should ban all urban areas!

[Albertkallal]

You should very proud of this great video. This is work that journalists should be doing! Copenhagen is about is dividing up money for everyone. CRU claims they can't share their data due to confidentially agreements. Yesterday the CRU admitted they lost those confidentiality agreements. So they can't share data until confidentiality agreements are resolved but now they are saying they did not keep those agreements! This grade school kid is doing a better job with more integrity then the CRU.

[kaffir2]

Brilliant work.

This is science.

[kpmailman]

Fantastic work! You had a hypothesis, analyzed the data, and came to a conclusion. For the alarmists, and the IPCC, this is called the scientific method. Models (GIGO) are not proof of anything but your own bias. I hope you follow your father's footsteps into science. You give us hope for the future!

[peterkmurphy]

Good study, son. I enjoyed this.

However, I am mystified by the other comments that conclude this disproves global warming. After all, if the rural temperatures remain the same, but the urban temperatures increase, then the overall temperature increase, doesn't it? Remember that American cities tend to sprawl, so that means there's more land that's hotter than otherwise.

Of course, the study needs to be redone to cover the whole world. Limiting it to America hardly makes it 'global'!

[UsuallyOptimistic]

re: "However, I am mystified by the other comments that conclude this disproves global warming....if the rural temperatures remain the same, but the urban temperatures increase, then the overall temperature increase"

No, I think if the urban areas were having an appreciable effect on the world, their warming would "leak" into the rural areas. I think you can do a reasonable analysis on just the rural data, ignoring the urban areas.

[nooze7]

Global warming scientists say the climate is warming due to man made CO2 not due to man made cities. They do not study the urban heat island effect

Due to this effect only readings from rural locations should be used and this video shows you why

[dadoody]

Exactly!

Urban areas studied have grown in population density (heat), industrial heat output, and traffic heat output, so of COURSE urban temps would rise in Urban areas, which Rural areas which have remained the same still have the same temperatures.

I agree that we need to design better ways to reduce CO2 emissions and pollution clean up, BUT the crap they're trying to pull in Europe having all of us pay is bullcrap/scam/money making.

All of the politicians involved are getting $ benefits

[JoshuaHedlund]

What the commenters are inferring is that if urban temperatures are increasing where nearby rural is not, than the urban data is suspicious; perhaps it is only going up because the thermometers are surrounded by urban heat sources -- not because that the globe itself is warming and contributing to melting ice, rising sea, etc...

[peterkmurphy]

What UsuallyOptimistic and JoshuaHedlund seem to want is to discard the data that doesn't agree with their conclusions (the urban), while keep the data that does (the rural). Now, I find THAT suspicious.

The urban area of the United States is 2%. Seems small, doesn't it - until you consider this is equivalent to states like Nebraska or Kansas. US Urban area is big enough to include temperature data from these locations. They need to be included in the total.

[dragonsjaws]

peterkmurphy, of course all data should be included in the total -- we skeptics are not dishonest like the British Climate Research Unit. But those urban temps should be weighted according to the area represented. According to your own figures, the urban temperatures should be weighted at 2% of the grand average of surface temperatures in the US. But that wouldn't provide much support for the warmists, would it? Because if only the cities are warming appreciably, it's unlikely CO2 is the cause.

[cajunastro]

Dragonsjaws: Because if only the cities are warming appreciably, it's unlikely CO2 is the cause.

Exactly! Could it be that as cites grow and we consume more energy, the more heat that is generated and the more the unnatural landscape traps heat from the environment and that's what's causing the warming? Human generated CO2 and other greenhouse gases have nothing to do with it.

[peterkmurphy]

Of course the urban temps should be weighed according to the area represented. However, weighing doesn't turn a increase into a decrease. Could they be linked to CO2? Cities have cars and factories.

Remember we are discussing an experiment done by one boy (and his dad) on climate data exclusively from the United States. It's great work, but trying to extrapolate from it to the rest of the world is ridiculous. The test doesn't handle ocean temperatures; most of the world's surface is ocean.

[dragonsjaws]

peterkmurphy, I agree with everything you just wrote. There is an increase -- in cities. On average, there is an increase in global temperatures, which we can see by various measures.

The cause remains obscure, IMO. The increase is not alarming to me, compared to past warming episodes (which I am convinced were not related to CO2).

I just wish science done on the larger scale showed the same elements of clarity and common sense present in this video, i.e. simple data analysis sans fudge.

[dadoody]

Yup.

The problem is though, is our politicians who are in league with people who are trying to create a "virtual" market for "carbon trading". They're trying to force "low carbon" products on consumers that aren't necessary. We do need to cut down pollution, and CO2 is only a small part of it. Global temperatures have dropped from the reduction of sulfur alone.

Right now in Copenhagen, some aristocrats are trying to force tax payers into paying 3rd world country funds for...??? They're scams

[tomintroy]

I deal with 1000's of data pools and have come to realize that the mean of a rather small sample is remarkable informative. Look at how closely the 'narrow' Dow-30 tracks the broad sp-500. One is a mere 6% of the other. K.I.S.S. KEEP IT SIMPLE STUPID.

[pondman27]

Agreed. I've done a similar excercise over 147 years for rural SE UK.

[pondman27]

Well petermurky, you statement is flawed beyond normal common sense logic.

I have done a very similar excercise and found the same thing. More over, the variations in weather reconcile well with Solar activity.

Lol so you are saying that the CO2 from cities stays over them and doesnt spread to the whole athmosphere? So if you like breathe a lot you get you own warm little climate around you?

I'm not mocking you, sorry, but basicly particles, such as CO2 spread in the air to even out to the whole athmosphere. For example the smell of food in the kitchen, it spreads out

This thing should be on the network news. Nice work, kid. Make more videos.

[LordDigbyChicken]

Excellent stuff. Thank you very much!!

[runntube]

nice job kiddo! ;-)

[sydneydoc]

Fantastic !!

Why aren't all school kids doing this sort of science instead of being spoon fed GW garbage !

For that matter, why aren't CRU scientists doing real science instead of fraud, lies and deception ?

[mikehdtv1080]

Great job! But if you want to get a grant you'll have to adjust that pesky rural data to show the hidden warming trend well known to all 'real' scientists :-)

[michael1166]

Nothing against Pat Metheny, but it's kind of distracting here.

[epeirce]

best part about this vid!

[Michaelwiseguy]

I would have expected this high level of scientific analysis coming from a 6th grade Asian student, not an American student. There is still hope for our country.

[Aeronomer]

He's probably home-schooled. Don't get too excited. Our public schools are all about progressive indoctrination. Any learning that takes place is due to good teachers despite a system run by a bunch of left-wing idiots. The secular progressives run the schools and every major city in the US. That's quite a track record. Sheesh...

[fabfinn]

Also of note is that in 1970 there were approximately 6000 global measuring sites while there are only some 2000 today.

The majority of the eliminated sites were rural.

Therefore, in addition to the urban sites having a bias towards higher temperatures individually, the overall data are skewed upwards since 1970 as the proportion of urban relative to rural sites has increased.

here in Sacramento we hit record low this week. last night was 25, and i took pictures of my water hose being frozen at 10in the morning... this of course doesnt mean anything, because the weather is unpredictable, but the trend in the last 5 or 6 years is pretty obvious.

have anyone seen Al Gore this morning on CNN? ;]]]] i feel sry for him, and CNN AM too

thanks Peter for your time :] keep it up

[Charlieutube99]

Is the GISS data homogenized/adjusted data or the original raw data for the stations?

Another interesting observation about temperatures is that the time-of-observation adjustments are almost equal to the total "observed" warming.

[HalogenFlood]

good job. thanks for posting your research.

[Rodmoly]

An excellent presentation but I would ditch the music which I thought was an irritating distraction! Otherwise really good stuff!

[turbozed]

This is the type of critical climate scientific method that should be taught to kids in grade school. Instead we are teaching kids to scold and rat out their parents for having incandescent bulbs and leaving appliances on.

[shirakawa2]

Excellent presentation

[joygarner]

Good job!

[zero1gmv]

welcome to my g20 and money games playlist...5/5 and you know dood, it is dec 7th and we here in the south east ontario area just got our first solid snowfall.

[rhorto01]

Go to Houston, TX where they have just had their earliest snowfall in recorded history.

Sheesh.

[zero1gmv]

i 100% agree, and the rest of the world is full of shit selfish kid, its tough i know.

good luck. but i'm sure if you figured out that, you'll figure out that the oxygen will be gone soon, or should i say it will lower to a level that is unable to support human life. awesome shit huh!

[Hroethbert]

"..the oxygen will be gone soon..."

Where do you come up with that idea? I really hope that you don't actually believe that.

[tHoM0r]

LOL

[zero1gmv]

yes isnt it lovely?

[OneManAndHisFiction]

This is explained in more detail by Professor Bob Carter in his presentation here on youtube; "Climate Change - Is CO2 the cause?"...

1. watch?v=FOLkze-9GcI

2. watch?v=vN06JSi-SW8

3. watch?v=iCXDISLXTaY

4. watch?v=bpQQGFZHSno

...very good presentation on this trend.

[dinkolino2]

you could publish this thing peer-review

[russdog63]

Excellent job and an important disclosure to the validity of the temperature data used to support global warming. A retired weather bureau employee wrote a letter to the editor in my hometown paper, the Wenatchee World, during a real hot summer a couple of years ago. He stated that the hottest recorded summer for Wenatchee was in 1938. Back then the data station was out of town next to an orchard. Now the data was taken from downtown Wenatchee surrounded by blacktop streets.

[BlueStateChronicle]

Data fraud isn't a game, kid.

Fail.

[TheseData]

There is no fraud here. Go to the GISS site an do the analysis yourself. Go look at the data and ask yourself why there are so many rural sites across the world (away from urban centers please) that do not show any warming. Go look up the Amundsen-Scot and Halley sites in Antarctica and ask why they show cooling. Don't trust anyone, look it up yourself.

[LibsRScum]

Lucky for you, assholery isn't a crime.

BTW - how's all that hope and change working out for you?

Hmmmmmmmmmmmmmmmmmmm?

[tHoM0r]

This kid discloses more data and methods than the alarmist 'scientists' do. In fact he's actually practicing science more accurately and honestly than most climatologists

[JonThm]

No, the wordl has been cooling fro 4 years.

[steam0001]

Awsome Video! Keep the good work!
