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

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

Glow Bucket — Thu, 26 Apr 2007 02:25:53 -0800

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.

Cow 'emissions' more damaging to planet than CO2 from cars

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.

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'

Mr Bluesky — Sat, 26 Nov 2005 09:08:59 -0800

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.
