Six degrees til doom (part 2)

[shoppittsburghnow]

some really good stuff here

[shoppittsburghnow]

love the video really good

[smuggecko]

really informative and interesting

[nazmak14]

and still there are people at large who vehemently deny and dis-credit the phenomenon of global warming, perhaps the sheer ignorance or naivety whatever it may be the mother nature when it takes it toll can be unforgiving.... go green folks else mother nature forces you to do so

[poodtang1]

Watch the series World Without Humans ans see how well the Earth does after we are gone.

[ApplesAreSweet]

I have an idea! Lets just PUSH the city away! Thumbs up if you remmeber that spongebob episode

[SuperMilka2009]

Everything will happen by God wills and nothing or no one can stop it.He created it and He can destroy it.We humans and everything else on face of the earth was created for nothing else except worship Him.

[bustermk2]

@SuperMilka2009 This why I hate religion.

The future is NOT in god's hands. It is in our hands.

Only we can save us ... not some invisible sky pixie.

[FantasticBob7000]

@bustermk2 Hate to disappoint you, the future isn't in our hands either.

[Shaqqid]

@SuperMilka2009 wait so your saying we should just keep polluting the atmosphere and die because you and a bunch of other religious psychos (This is not about every religious person, just the ones like this guy) think the all mighty god wants us do cause the world to become inhabitable?

ill be dead so i dont care

[jsbennett86]

It is a small change, yes, but keep in mind that it's averaged across the globe all year. Temperature changes are likely to be much higher at the poles, and at different times of the year. Small changes to the planet's equilibrium can also have a run-away effect, causing temperatures to rise continuously. This is what appears to have happened on Venus (though I doubt our outlook is that grim by far) .

[3xTube]

The big question - IF that is our fault, then after the temperature rise and all those billions dying of hunger and diseases, the Earth will regain it's balance. Then after some hundred(s?) years humans will be able to live normally (like in the middle ages).. If the Sun, not us is to blame, well, what can we do? Fly away? Chose the caps for comfort living?

[followthefleet1]

@3xTube ...The sun was at the low end of its activity cycle from 2000 to 2010, yet this decade set the all time temperature records. Another variable is water vapor...but people should realize that while it reflects heat away from earth, it also acts like a green house gas, to contain heat. The climate science today supports man induced climate change. And yes, SOME of the scenarios from this, will change the earth, to what James Hansen calls a 'different planet'

[followthefleet1]

OK...So 6 degrees C X 1.8 = 10.8 degrees F. It sounds high...from a completely unscientific perspective. So...Once again, if anyone knows, the IPCC low end projection, for global temperature rise, is for a 2.5 degree C temperature rise, or a 4.5 degree F. This has consequences also...and I understand, that this low end projection is the one that has been criticized as too low.

It doesn't seem that humanity will escape consequences of it own modern culture, however you slice it.

[Legomakerx]

@followthefleet1 it's C x 1.8 + 32 = 42.8 DEGREES!?!? OMFG, that will be super hot. No way we'll survive...

[followthefleet1]

@Legomakerx I'm not sure what you are converting. I'm just taking one degree Cent. to equal 1.8 degrees Far. I don't know about survivability, but we ARE facing a "different planet". Note that temperature change will be greatest at the poles. This means that the scenarios for ocean rise..geo-historically related to mass extinctions..will also be in play. It seems that humanity is hard wired only for immanent crises. The stealth nature of this crisis is a huge economic and political challenge.

[Legomakerx]

@followthefleet1 its converting C to F. besides, your forgot adding 32 for converting C to F.

[followthefleet1]

@Legomakerx ...If you know that 1 degree C. = 1 degree F., you ARE converting it. Things are bad...but not 42.8 degrees bad! Thank God. The proposed goal is to limit warming to 2.5 degree C...which is 4.5 degrees F....which is still a tremendous amount of heat over the surface of the earth.

[Legomakerx]

@followthefleet1 surely im converting C to F correctly?

[Legomakerx]

@followthefleet 1 degree C is above the freezing point of ice. 0 degrees is the freezing point. 32 Degrees F is the freezing point of ice too, im sure what im doings correct

[followthefleet1]

@Legomakerx ..Yes your formula is correct, but you don't need to do it that way when a direct conversion is all you need. All the narrator says, that there's a range of 2 C degrees to 6 C degrees in the projections of temperature in 2100. He is NOT saying that the earth temperature is 2 degrees. So all you need to do is know 1 C = 1.8 F...to get the range of the potential increase. The actual temperature of the planet is around 16 degrees C, if I'm not mistaken. You can check that on WIKI..

[jsbennett86]

@Legomakerx

This is wrong. You only need to add 32 when computing where a temperature lies along the scale, not when determining the magnitude of a temperature change.

[jsbennett86]

@Legomakerx

So if you add the 32 when converting to an absolute place on the scale, you get 0C * 1.8 + 32 = 32F (correct) and 100C * 1.8 + 32 = 212F (correct).

[jsbennett86]

@Legomakerx

However, if you add the 32 when calculating the magnitude of the change, the result is ridiculous. For example, if 1C difference was equivalent to 1 * 1.8 + 32 = 33.8, then 0C would be 0 * 1.8 + 32 = 32.0. ZOMG! Increasing the temperature by 0C increases it by 32F! This is even more absurd if you do that while lowering the temperature. If you increase the temp by -1C (i.e., reduce it by 1C), the conversion is -1 * 1.8 + 32 = 30.2. ZOMG! Lowering the temperature increases it!

[Legomakerx]

@jsbennett86 but that's the way of converting C to F, otherwise, it's wrong, isnt it? WHY NOT ADD 32!?

[jsbennett86]

@Legomakerx

Did... umm... did you read my comments? You only add 32 when calculating the absolute place on the scale (e,g, it's 30C or 86F outside), not the interval or changes along the scale (e.g., the temperature just went up 4C or 7F).

For more info, see the Celsius Temperature Conversion Formulae sidebar at the top of the Wikipedia article on Celsius.

[Legomakerx]

@jsbennett86 oh, ok. but 4 - 6 degrees itself is very little degrees increase, but i don't see how that much is gonna do alot to the world

[followthefleet1]

I probably missed it...but is the narrator saying 6 degrees F., or 6 degrees C.?

[metaljOhNnYsSs]

@followthefleet1 C

[ghjjfsbf]

4 degrees sounds about perfect.

Lets shoot for that.

[daveeol]

its a good thing this is all fantasy or else i might scared

[JayCKat]

@daveeol

Not really. The average global temperature is 15 C and we are just coming out of an ice age. During the height of a warm period, global temperature are about 22C. During the time of the dinosaurs it was estimated to be about 27 C (big global desert). And during the time when the our coal deposits (which we are burning) were laid down, estimated global temperature was 30 C.

[USAneedsaChange]

thanks for uploading this, great show

[kick2299]

this video relys on two major things.

first it relys too much on emotion. they make you feel afraid about antropological global warming. they do this by useing ominous music and video of people who are in strife

the onther thing this video reys on is the earth being very old, which is only a theory, and that green house gasses are what's causeing the warming. these are both theorys. instead of thinking what science wants us to believe, look for your self. check out CLIMATE-GATE

[shriramvenu]

likewise friend god creating the world in 6 days and the story of adam and eve are also juust theories...

the difference? once comes from a book with no evidence whatsoever. another has at least SOME evidence and is constantly open to debate and evolving as we learn more of our history

[girlslaw17]

nobody really cares about it. A lot of people do, but people carry on as normal. Hopfully it wont rise much.

[dankdank]

its Al Gores fault.

[sluterry]

lolfr al gore is a complete loser his only response to debate is "well thats plain wrong" and "but i thought the debate was over" etc etc hes suck a loser its not funny
