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.

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. [more inside]

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

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.

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.

Sounds like it's time to buy that lovely oceanfront property in Kansas.
