The trouble with terraforming Mars...

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]

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

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

It is not on you to finish the work, but neither are you free to desist

Joseph Tomaras reflects on the Mauna Loa data and concludes that the main tasks of the moment are neither political nor economic, but ethical or moral. [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.

Air-capture startups

Three startup companies led by prominent scientists are working on new technologies to remove carbon dioxide from the atmosphere. These scientists have launched start-up companies and attracted well-to-do investors — most notably Bill Gates — along with venture capital and, most recently, the attention of Wall Street.

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.

"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)

Buy yourself a tonne of CO2 emissions

sandbag.org.uk is a not-for-profit website that allows members to buy up surplus "permits to pollute" that form the currency of the European Union's emissions trading scheme (or EU ETSs). Members can then "retire" them so that they cannot continue to be traded between the industrial polluters - cement, steel and car manufacturers etc - forced by EU regulation to operate within the system. "I suppose it's a bit like burning money in front of someone so they can't spend it on something bad," says the founder, Bryony Worthington, to the Guardian. [more inside]

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.

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.

“People are asking questions of the science that science can't answer.”

Climate change a 'questionable truth'. Margaret Wente looks beyond the hysteria surrounding the climate change debate. Hysteria her own newspaper has been contributing to.

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.
