2012 sees slowdown in the increase in global CO2 emissions

From the Netherlands Environmental Assessment Agency... (Interactive Presentation)(Actual Report PDF) Actual global emissions of carbon dioxide (CO2) reached a new record of 34.5 billion tonnes in 2012. Yet, the increase in global CO2 emissions in that year slowed down to 1.1% , which was less than half the average annual increase of 2.9% over the last decade. This is remarkable, as the global economy grew by 3.5%. This development signals a shift towards less fossil-fuel-intensive activities, more use of renewable energy and increased energy saving. Increases in fossil-fuel consumption in 2012 were 2.2% for natural gas, 0.9% for oil products, and 0.6% for coal.

This does not stink.

Ultra-prolonged activation of CO2-sensing neurons disorients mosquitoes. It’s hard to hide from a hungry mosquito: the insects home in on their human targets by detecting body heat, carbon dioxide, and odors. Repellents containing DEET ward off mosquitoes and other bugs, but until recently (pdf) no one knew why. Some research indicated that mosquitoes smell and avoid the insect repellent DEET. (pdf) Armed with the knowledge that carbon dioxide (CO2) present in exhaled air is the most important sensory cue for female blood-feeding mosquitoes.... [more inside]

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]

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.

CO2 make dumb

Have you ever been in a room with lots of people and not great ventilation. Or even a room with normal ventilation. You may be cognitively impaired due to elevated levels of CO2 once considered safe now thought enough to make you a little dumb. 600ppm is now thought too much, but “there are plenty of buildings where you could easily see 2,500 ppm of CO2 — or close to it — even with ventilation designs that are fully compliant with current standards.. classrooms frequently exceed 1,000ppm."

"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

Earth doesn't have an energy problem; the Earth has an energy carrier problem

Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues have co-authored a paper (doi: 10.1021/ja2100005) in the Journal of the American Chemical Society describing a novel, cheap material that scrubs CO2 from ambient air, even at the very low concentrations of the atmosphere. The material is easily manufactured, and carbon captured is readily removed from the polymer, allowing recycling of the polymer and sequestration of the carbon. The researchers, co-authors of Beyond Oil and Gas: The Methanol Economy regard this as more than simply a technique for decreasing the carbon emissions of industrial processes and fossil-fuel burning machines, but as possibly an energy-carrier, by using the "catalytic hydrogenation of CO2 with H2 where the hydrogen has been obtained from water electrolysis (wiki).

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."

"They died in the houses, in streets, outside the forest, in the stream."

One of the most dangerous places on Earth, Lake Nyos in northwestern Cameroon sits atop a volcanic source. Early evening Aug. 21, 1986, a cloud of deadly CO2 erupted from the lake surface, killing an estimated 1,700 people and 3,000 cattle.. Now people are trying to tame it (Via NucleophilicAttack via Metachat)

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.

2007 equal second hottest on record

Climatologists at the NASA Goddard Institute for Space Studies have found that 2007 tied with 1998 for Earth's second warmest year in a century (2005 being the hottest). More here. of course, others disagree.

Filtering our air

The University of Columbias Earth Institute has successfully demonstrated carbon dioxide air capturing. As to what could be done with the carbon dioxide after, the IPCC has some ideas (pdf). Unfortunately they don't state how much energy these machines consume or how expensive (toxic, etc.) their prodction is going to be.

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.

Chill, Toronto

Cool! Toronto's Deep Lake Water Cooling System was launched today. The system cuts electricity consumption in commercial buildings by 75 per cent by drawing near-freezing water through pipes extending five kilometres out into Lake Ontario. According to the city, the system will save enough power to service more than 100 Toronto office towers or 4,200 homes per year, and it will eliminate 40,000 tonnes of carbon dioxide. Here's a public television segment explaining the process. Seems like it makes a nice complement to the lakeshore windmill.

China pops back a collective Beano.

China pops back a collective Beano. (NY Times link. Free registration required.) One of Bush's main objections to the Kyoto protocol is China's exemption from regulation, but it seems they're doing their collective best to cut down on CO2 emissions, with success. Even with China's rapid rate of expansion, this weakens our administration's argument a bit by setting forward the number of years it will take China to match our own emissions. At what point do we start to play nice with the other kids?

what should we be doing to voice our opposition to dangerous, gas-guzzling, CO2-emitting, vision-obstructing, environment-destroying conspicuously-consumed SUVs? what can one do to prevent others from driving these monstrosities? should we ticket them? should we stick "i'm changing the climate" stickers on them? should we stick potatoes in their tailpipes? should we shoot out their windows? is there any way to educate suburban families that SUVs are simply an unnecessary addition to their lifestyle? should we resort to retaliatory vandalism? can SUV owners ever have a meaningful discussion with those who object to their vehicles? i do my part by not buying an SUV, but could i do more? should i?
