Arctic Sea Ice (Jan 2000 - May 2009)

[mrteemumilto]

So KlimaC comes from climax and campus comes from your college fantasies?

[raanaj]

"No evidence at all" for anthrocentric climate change. Yet every climatoligst on earth thinks that's what's happening; some random youtube poster knows better? The change in global temps far exceeds the pace of any previous recorded change due to sun activity, ice ages, whatever. Of course human activity has an effect; drive from country to city and you experience microclimate changes; it's completely reasonable to assume that the same thing happens on a mass scale; evidence confirms.

[parks0213]

@raanaj There is absolutely no evidence of anthropogenic contribution to climate change. CO2 is only .054 % of the atmosphere . CO2 is a Greenhouse gas but H2O , which is also a greenhouse gas is 95% of the atmosphere. Solar winds, cause by significantly increased solar activity,and a doubling of the Sun's magnetic fielf during the 20th century...these have caused changes in weather patterns.

[parks0213]

@raanaj The lying politically and money ( grant) motivated scientists have purposefully misled millions of ignorant people and played into the hands of marxist/socialist anti-capitalists wanting to destroy the USA. Any scientist worth a shit knows that increases in CO2 in the atmosphere FOLLOWS increases in temperature...not the other way around.

[parks0213]

@raanaj AND increases in temperature are cause by increases in the Sun's activity...spots, flares causing solar winds which cause a reduction in cloud formation....clouds cool the air near the ground and cause precipitation which also cools the air. Solar winds disrupt the formation of clouds causing warmer weather and changing weather patterns. Even the IPCC claims that the temperatures have been cooling since 1998.

[RBAWilcox]

The earth goes through different glacial periods, during an interglacial period like the one were in right now there is no ice at the poles, just like during the time of the dinosaurs there was no ice at the poles, and there are glacial periods where the earth plunges into an ice age. People are concerned about nothing the earth will continue to lose its ice at the poles until the next ice age starts up in the next 20,000 years or so.

[badbobby101]

i dont see no change so whats this big deal with global warming?

[GreyGeek77]

mmm.... rolling the film back and forth between March 2000 and March 2009 and comparing the maximas of the ice sheets at each of those periods, I fail to see a significant difference.

[vengance89]

Atmospheric concentrations of CO2, the principal driver of climate change, have climbed from nearly 280 parts per million (ppm) when the Industrial Revolution began around 1760 to 387 ppm in 2009.

Not "conclusive", as in we can't do an experiment that wouldn't involve destroying the earth, but definitely alarming... maybe enough to say, well, if there is a chance that this is real, should we take the risk and not do anything?

[vengance89]

To labour the point, some people can't help but care about the earth. The 25 warmest years on record have come since 1980. And the 10 warmest years since global recordkeeping began in 1880 have come since 1998.

The area of the globe experiencing very dry conditions expanded from less than 15 percent in the 1970s to roughly 30 percent by 2002.

[BaronVonLichtenstein]

As Al Gore might say, "Climate is like a box of chocolates. You never know what you're gonna get. "

[vengance89]

@costatropicalgranada

climate change is real. it is undeniable, the climate is changing, we are changing it, it is a destructive relationship.

[costatropicalgranada]

@vengance89

Of course climate change is real. The climate has been changing for millions of years. There is ZERO evidence that we are changing it, or that the effects have been, or will be, destructive. And specifically, there is no evidence whatsoever that human carbon emissions are affecting the climate.

[vengance89]

@costatropicalgranada

Every time you drive a car you change the climate, and it is pollution emitted. That is a necessary implication. We pollute the environment, this changes the climate. It destroys ecosystems. This is happening worldwide. It is pure logic to say that pumping CO2 into the climate is changing the climate. The evidence is undeniable, species are becoming extinct at a rate of 150-200 species per day... Man destroys ecosystems. CO2 or not, man made climate change is real.

[costatropicalgranada]

@vengance89

Rubbish. For a start, CO2 is NOT "pollution". It's what plants need to grow.

Yes, we pollute the environment with toxic waste, but CO2 is neither toxic or harmful to the environment.

It is not even remotely logical that "dumping" CO2 into the atmosphere is changing the climate. In fact it's an idiotic thing to say. There is no scientific evidence whatsoever that CO2 can damage or alter the climate. You say the evidence is "undeniable": WHAT evidence? There is none.

[vengance89]

@costatropicalgranada

the logical side is that by adding CO2 the climate is changing, that is undeniable. It is changing in physical composition. Whether the CO2 is ultimately harmful is speculative, but there are things that suggest it is adversely affecting the earth. Ultimately this is simply a risk we're taking, that is why there are annual international meatings (COP) to debate the action to be taken concerning this threat.

[costatropicalgranada]

@vengance89

No, it is not at all "logical" that increased levels of CO2 are changing the climate. This is a nonsensical claim without a shred of scientific evidence to support it. If anything, higher levels of CO2 in the atmosphere would have a beneficial effect, by promoting growth.

There IS no threat from CO2.

[vengance89]

@costatropicalgranada

I listed the rainforests a long with many other facts as climate change aside from CO2. "Climate change", literally, is a climate changing. "Logic" is the study of reasoning. If you take a microclimate, say a room, then add CO2 to this climate, you have changed it. The same is true on any scale. The same happens when you add any pollutant or kill a species that performs an important role. It takes no science to support this, it takes logic.

[vengance89]

@costatropicalgranada

I personally feel that CO2 is not as worrying as the other aspects of climate change. Namely killing off the oceans and desertification. There is no debate as to whether that is bad or not. The ecosystem is a balance, changing the factors has affects the ecology. Is CO2 as dangerous as the world's leading scientists claim? I don't know, but don't want to take a risk. Is the overconsumption of the human race bad? Yes, we are destroying the earth for our comforts and hobbies

[vengance89]

@costatropicalgranada

you should really see this video

Bill Maher lays waste to Global Warming deniers

youtube.com/watch?v=0OwFSLm4pI­I&feature=related

[costatropicalgranada]

@vengance89

Yes, I've seen that video. It shows the entirely natural and normal cyclical expansion and retraction in the Arctic ice. And when ice levels decrease at the Arctic, there is a corresponding INCREASE in the Antarctic (which alarmists never talk about).

Bottom line? Global ice levels are 100% normal.

[silva6939]

@costatropicalgranada ... yeah there is.. What are you smoking?

[m0deth]

@costatropicalgranada

I seem to recall a few simple experiments on the Discovery channel that proved the effects of CO2 in a small enclosed environment. These were conducted to prove something related to the show, and to illustrate how gases can affect their environments. Anyone familiar with scientific process can deduce, from those findings, that scaled up, there would be a significant impact. This is not to say it would or wouldn't be catastrophic....but to claim no shred is sheer ignorance

[costatropicalgranada]

@m0deth

That experiment has no relevance at all to CO2 in the real world.

The amount of CO2 used is grossly disproportionate. And secondl, the earth is not a closed system. It is an open, dynamic system involving myriad factors that do not apply in a glass jar experiment.

There is no evidence that CO2 is harmful to humans or animals; and it is positively beneficial to vegetation. And there is no evidence at all that human produced CO2 causes global warming.

[uknowispeaksense]

@costatropicalgranada What about the effect of the change in CO2 atmospheric composition in terms of isotope ratios? C4 and CAM plants tend to favour heavier Carbon isotopes than C3 plants. Introducing CO2 from the burning of fossil fuels alters the isotope ratios in the air and so benefits one group of plants over another potetnially altering ecosystems so to use a stement like ' it is positively beneficial to vegetation' is not only oversimplified it is also patently incorrect.

[vengance89]

@costatropicalgranada

Your right, CO2 is converted by plants, it is however only one of the greenhouse gases. Regardless of this aspect of climate change, half the rainforests have been destroyed, 3% of arable land is converted into desert each year, less than 10% of big fish populations remain, there is 6x more plastic than plankton in the bowl of the pacific ocean, the tiger, cheetah and lion are facing extinction, 1 billion humans are malnourished, the water between China and Japan is

[costatropicalgranada]

@vengance89

Rubbish. Some of the rainforests have been destroyed by over-harvesting and land clearing. CO2 levels have nothing to do with it (in fact higher levels of CO2 would promote more growth).

Stick to facts if you want to be taken seriously.

[vengance89]

@costatropicalgranada

infested with jellyfish, ecologies are collapsing everywhere. The great barrier reef, the amazon, there is too much evidence to bother listing that humans are destroying the environment, on micro to macro scales, and that we have the hubris to believe we can get away with it or find a technological solution. The environment will not be our concern however, because societies are collapsing as well, Greece, Ireland, US, the end of oil and the need for harmony with the earth.

[BaronVonLichtenstein]

I took a screen capture of Jan 2000 and Jan 09. If anything there was more ice in Jan 09. Do it yourself and tell me Im wrong.

[vengance89]

@BaronVonLichtenstein

climate change implies more severe extremes

[brandouxp]

peace guys cant we just all be united and slow down the global warming?

[roflcopter2006]

Man Made Global Warming? lolz

You tin foil hat wearers sure are funny.

[FreeAgain2]

Watch

Doomsday Called Off

- it's Harvard scientists debunking the Hockey stick and more

[Paladiea]

That's nice. Do they have a peer reviewed paper also or merely just a propaganda piece?

[FreeAgain2]

There are so many peer reviewed scientific publications that Debunk AGW that your head should be spinning. If  you don't know of them - you are't looking very hard.

[Paladiea]

Name one.

[FreeAgain2]

Monnin et al. (Science vol 291, p112, 2001) find CO2 lags last interglacial temperature increase by 800 years.

Showing that CO2 does not drive temps.

[anwaya]

Monnin shows nothing of the kind: it only claims to show that the last ice age ended without a dramatic rise in atmospheric CO2.

So you have produced no irrefutable proof of any of your conclusions. Can you refute the 19th century work of Fourier, Tyndall and Arrhenius? I don't think any of your sources of delusion have.

[j0hnwi11iams]

CO2 is reflexive. There is a positive feedback loop. Warm temperatures tend to release carbon dioxide. Carbon dioxide is a greenhouse gas that traps infrared energy. This makes the response to manmade CO2 non linear.

[Paladiea]

What everyone before me said. Also, there's a greenman video on the topic. I suggest you watch it.

[anwaya]

Harvard astrophysicists, not climatologists. That makes them experts - right? No?

[FreeAgain2]

The question to ask is - if HALF the arctic melts in the summer and there is NO RISE in SEA LEVEL why would melting the other half flood our coast lines?

[ProtoCosmos]

It's not the melting Sea Ice that would raise the water levels, it's the melting Land Ice that drains off and/or slips off the land that would displace the extra volume.

[anwaya]

ProtoCosmos, you're right.

[anwaya]

The arctic sea ice is floating, because its density is lower than that of the sea water. The volume of water the sea ice displaces is equal to its volume when it's melted.

Therefore, when the sea ice melts, it does not cause the sea level to rise.

However, more than just sea ice is melting: Greenland and Antarctica are both covered with ice sheets which, as they melt (and they are melting), flow into the sea. This is what is going to cause the sea level to rise. With disastrous consequences.

[FreeAgain2]

I can only state that the warmer temps are not caused by mankind.

Science is numbers.

Not pretty pictures of polar bears or ice falling into the oceans.

Temps vary greatly. Parts of the Antarctic are growing - Marco Tedesco and Andrew J. Monaghan, An updated Antarctic melt record through 2009 and its linkages to high-latitude and tropical climate variability, Geophysical Research Letters, 36(2009), p. L18502

[teknikal33]

Yes you can only state; not demonstrate through research.

[cat1012000]

humm.. I get it. Less snow in summer. More snow in winter. In fact, as I watch this it seems that there is progressively more snow each year. Where's the global warming?

[raseclarbac]

amazing, all politicians need to see this video. it is time to act. one day we will see wars because the northeast passage. the time for stop the warming is now.

[teknikal33]

Anecdotal observation that means nothing. The slight warming at your latitude, although not above freezing, allows the atmosphere to hold more water resulting in a localized increase in frozen precipitation. The closer to the equator the smaller the increase in average temperature. As you get closer to the poles there is a greater increase in average temp.

[raseclarbac]

shut up and be quiet, you stupid ignorant idiot.....

don´t try to explain what you do not understand .

your brain is to small to connect all the simple complexity of global warming..

go to Bangladesh and died , smart boy

[myjunno]

seems like nth is changing?

[LovelyYTRocks]

Pretty cool.

Comparison data for 2005, 2006, 2007, 2008, 2009 August?

I bet we have a record for smallest ice cap this year.

[RomeoMD25]

Global Warming fantasies that the earth is becoming one giant microwave heated up by man"s pernicious and insatiable industrial development is of course ridiculous. The only consensus

that exists on climate change is that if you believe anything the UN or Al Gore says, you are probably a moron
