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.

Want to know what actions can have the biggest impact on your carbon emissions? Bloom helps you choose actions tailored to your home and lifestyle, then lets you compare them by how much CO2 they save and how cheap they are. With background guides for recycling, organic foods, energy ratings, and emissions. From the BBC.

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.

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.

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.

Lawrence Livermore National Lab produces fascinating charts of energy flow in the US (more). More energy use statisitics can be found at the Energy Information Administration.

Livestock's Long Shadow, a new UN FAO report (full report) says livestock (cows, pig, sheep, etc.) generate more CO2 than all forms of transportation (cars, planes, etc) combined, with the worlds live stock expected to double by 2050.

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' 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.

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. (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?
