E/E invites discussion or any subject pertaining to the environment (biodiversity, pollution, GM crops, population et al); energy (fossil fuels, renewables, and the great nuclear pie-fight); and of course climate change/resource use which links the two. Peak oil related posts are also welcome, but don't forget the peak oil group.

If you've got questions about climate change feel free to ask, but if you repeatedly post denialist rubbish you are liable to be shown the door...

Updating Feb 2019 (Sorry for the wait. I've been tired and shagged out following a prolonged squawk).

Carbon Dioxide

Carbon dioxide ( CO₂ ) is the GHG that gets discussed the most, because of the sheer amount we produce (9 billion tons in 2010) and because so much of our existing energy produces it. The best guess for a sustainable level is 350 ppm, so... Yeah. Good luck with that.

Long term trend (Source: NOAA):

Emissions by region (Source: EIA):

Emissions by sector (Source: OWID)


Methane ( CH₄ ) is a hundred times more potent (by mass) than CO₂ over a 20 year period: Although it does break down over time, the total amount in the atmosphere is increasing, largely due to melting clathrates in the oceans and permafront.

Other GHGs

Nitrous Oxide (Source: NOAA)
N₂O is mainly released from fertilizer, is about 200 times more potent than CO₂, with a lifetime of ~120 years.

Sulfur Hexafluoride (Source: NOAA)
SF₆ is used in industry, is about 36,000 times more potent than CO₂, with a lifetime of ~6,000 years.

[div id="secres"][font size=4 ]Responses to denialist claptrap[/font]
Claim: CO2 followed warming after the last ice age.
[div style="width: 60%; float:right"]
Details: Rather than an increase in CO2 causing increasing temperatures at the end of the last ice, the increase in CO2 was caused by increasing temperatures. Therefore, we don't need to worry about increasing CO2 now.
Response: A test of 80 temperature proxies referenced against CO2 levels (from air trapped in ice) shows that the the CO2 definitely came first. A fuller explanation can be found at http://www.livescience.com/19481-ice-age-carbon-dioxide-orbit.html, and the paper is at http://www.nature.com/nature/journal/v484/n7392/full/nature10915.html

Sorry if I'm being dense but does the NOAA CO2 graph show us at 393 ppm? truebrit71 Jan 2012 #46
Why, yes it does... Dead_Parrot Jan 2012 #47
Right, although 350 ppm has been suggested as an initial target OKIsItJustMe Jan 2012 #48

Right, there are a number of strategies that might be used OKIsItJustMe Jan 2012 #53
Yeah sorry, 350 was the number I meant... truebrit71 Jan 2012 #50
Yeah? So what? Show me PROOF that global warming is real, not just a bunch of charts. Kablooie Feb 2012 #54
