Global warming, fact or fiction?

[King Edward]

Does anyone, truely NOT believe that global warming is happening?

 

[Nic]

nope its all in our heads the atmosphere is not affected at all by us putting billions of tons of crap in it every year...

Might have been better if you put, man made global warming, instead of just global warming. I think that is the issue.

 

[Kobeclone]

I believe man made global warming is occuring....

I'm not on either side of the debate at this point, but I will say that to attempt to use 150 years worth of weather research to determine where a 4 billion year old planet is going is a real stretch.

Ice cores give us a good record of the climate going back millions of years...its only a 150yrs someone has looked out the window and written it down.

I get your point, but if its happening its happening, and the real question is what we gonna do about it?

There's actually a lot more research than that. Antarctic temperature data and global CO2 concentrations calculated from proxy sources like ice boreholes have shown that current antarctic temps and CO2 concentrations are the highest they have been over the past 650,000 years. Taken from the EPA (Bush administration run EPA, no less!) climate change website:

Yeah, we don't have 4 billion years of data, but the evidence of rising temps and CO2 concentrations goes far past 150 years.

For those of you who are interested, I recommend the EPA's climate change page for information on this issue:

Where's David Webber when I need him?

Anyone who doubts an increased greenhouse effect due to increased atmospheric CO2 need only look next door, to the planet Venus, where lead is a liquid. Whee!

 

[johnptc]

the issue is not whether there is a global warming trend..

the question is whether it part of a natural cycle and or does mankind's activities affect it at all, somewhat or a lot
