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.

Earth, 2100 AD.
has doubled to 1000 ppm. From shore to the horizon, there is but an unending purple color -- a vast, flat, oily purple. No fish break its surface, no birds. We are under a pale green sky, and it has the smell of death and poison.
Paleontologist Peter Ward's new book
links past mass extinctions to global warming and shows
, absent major changes, "Our world is hurtling toward carbon dioxide levels not seen since 60 million years ago, right after a greenhouse extinction."
Maybe it's time for a heresy
: nuclear energy's green, and renewables aren't.

More gloomy news
on the whole climate change thing. It seems that Greenland's ice caps are melting three times as fast as previously measured (ultimately, in a thousand years or so, leading to a 6.5m sea level rise). While at the other end of the planet, it's not snowing as much as we hoped
to limit sea level rises. But hey, we can still laugh about it

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.
