2012 Rise In CO2 Levels Second-Highest In 54 Years

The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees as many global leaders have hoped. [more inside]

I'm sure all the CO2 isn't exactly HELPING, but...

Global warming may be caused more by CFCs than CO2. Paper here.

CO2 to hit 400 parts per million next month, highest since the Pliocene

Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million. Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

2012 Rise In CO2 Levels Second-Highest In 54 Years

The prospects of keeping climate change below that (2-degree goal) are fading away. Scientists track carbon pollution both by monitoring what comes out of factories and what winds up in the atmosphere. Both are rising at rates faster than worst-case scenarios that climate scientists used in their most recent international projections.

"all gone by 2015"

While the 2007 IPCC report showed Arctic sea-ice still present in 2100, it is now an unfolding "global disaster" according to Cambridge Professor Peter Wadhams. Climate Code Red summarizes the science, saying the sea-ice is "in a 'death spiral' and likely to be gone in summer within a few years" ... "The sea-ice volume is now down to just one-fifth of what it was in 1979", and paints a newly emerging, rapidly worsening climate picture, urging climate scientists to sound the alarm on new data showing a world on the brink of dramatic tipping points, far sooner than anyone anticipated

If we keep doing what we are now doing, we will face unthinkable catastrophe

"Climate change will take on a life of it's own and spiral out of control. Something like half the earth's currently-inhabited land would become too hot to survive on. I don't mean it's difficult to grow beans, or your air-conditioning bills are inconveniently high. I mean, if you go outside you die of hotness. Places that were an average of 80F will now be an average of 170, 180F. Will there still be human civilization under those circumstances?" - a TEDx talk on The Brutal Logic of Climate Change, by David Roberts of grist.org

Oops!

Carbon dioxide emissions increased by the largest amount on record in 2010, exceeding the worst case scenario outlined by the IPCC four years ago.

Executive Decarbonization

With the climate bill dead and blame portioned, Ezra Klein asks what happens when congress fails? He concludes that "regulations to reduce carbon emissions are alive and well. The Environmental Protection Agency can attack carbon as a pollutant, and the Obama administration's announcement that efforts to hamstring the EPA will be vetoed suggests that they mean to do exactly that."

The 4th degree

80 percent of Americans say global warming is real and poses a threat to humanity. Which is good because if the global temperature raises by 4 degrees we're all dead. However only 44 percent would be willing to face any financial hardship in the name of a solution.

Sucking CO2

Sucking CO2 out of the air has long been a holy grail for solving global warming; Richard Branson has promised $25m to anyone who succeeds. Of course it's already been done, but the amount of energy required doesn't make it net carbon positive. Now a team in Arizona, led by Klaus Lacknet under the company of Global Research Technologies, says it has made a significant breakthrough that massively reduces the amount of energy required - the "project has reached the stage where it is quite clear we can do it." The planned prototype, which will be finished in two years, will cost $200,000 USD, be smaller than a shipping container and be capable of eliminating around 1 ton of CO2. Even if it works many hurdles remain but it portends a cooler future for air-capture technology.

A million years

Ice bubbles collected from core samples in Antarctica reveal the biggest rise in CO2 in 800,000 years.

algae power

Will algae defeat global warming? "Fed a generous helping of CO2-laden emissions, courtesy of the power plant's exhaust stack, the algae grow quickly... The cleansed exhaust bubbles skyward, but with 40 percent less CO2... The algae is harvested daily and a combustible vegetable oil is squeezed out: biodiesel".

CO2 'highest for 650,000 years'

CO2 'highest for 650,000 years' Current levels of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the past 650,000 years. (Found via Treehugger) Sounds like it's time to buy that lovely oceanfront property in Kansas.

Canada Ratifies Kyoto

Canadian Paliament ratifies the Kyoto Accord. Someone on this continent had to do it.
