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.

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.

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.

“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.
