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.

...and the news ain't good: "Evidence for climate change abounds, from the top of the atmosphere to the depths of the oceans. This evidence has been compiled by scientists and engineers from around the world, using satellites, weather balloons, thermometers, buoys, and other observing systems. The sum total of this evidence tells an unambiguous story: the planet is warming."

Meteorologist and climatologist Barbara Mayes Boustead has loved the Little House books since she was a little girl
. At her blog Wilder Weather, Barbara makes "connections between weather and climate concepts, events during Laura’s time and in her books, and present or future weather and climate concerns
." For example, in October of 1880, a storm is brewing.
"The initial shot of cold air brought near-freezing temperatures and a little bit of precipitation up north on the 14th. The low pressure system deepened on the 15th as it got spinning in eastern Nebraska, pulling cold air around behind it while it brought moisture up from the south. Then, the low pressure just sat there for a while and deepened. As it got deeper, the winds behind it – in eastern South Dakota – got stronger. The storm stayed in the area of northwest Iowa to southern Minnesota
through the 16th, then pulled away into northern Michigan on the 17th, leaving cold air and breezy conditions behind it." And in De Smet, South Dakota, Laura Ingalls and her family settle in for the beginning of the Long Winter

In a report released [Tuesday], the World Bank analyzed the consequences of allowing temperatures to reach 4°C above pre-industrial levels by the end of the century. ... the report's authors admit that predications are a challenge. Still, they do their best to try to paint a picture, and boy, is it grim.

A Message from a Republican on Climate Change:
I'm going to tell you something that my Republican friends are loath to admit out loud: climate change is real. I'm a moderate Republican, fiscally conservative; a fan of small government, accountability, self-empowerment and sound science. I am not a climate scientist. I'm a Penn State meteorologist, and the weather maps I'm staring at are making me very uncomfortable.

Did the Little Ice Age start with a big bang?
According to the new study, the Little Ice Age, a period of cooling temperatures that began after the Middle Ages and lasted into the late 19th century was triggered by repeated, explosive volcanism and sustained by a self- perpetuating sea ice-ocean feedback system in the North Atlantic Ocean

In January, 16 scientists and/or engineers wrote an opinion piece in the WSJ. This is the response
of one of the academics cited in their piece: William Nordhaus. According to the 16 scientists/engineers, Nordhaus recommended no action on climate change for 50 years. But he didn't. The opinion piece
has generated controversy
among climate scientists as well.

"Speaking for many scientists and engineers who have looked carefully and independently at the science of climate, we have a message to any candidate for public office: There is no compelling scientific argument for drastic action to "decarbonize" the world's economy. Even if one accepts the inflated climate forecasts of the IPCC, aggressive greenhouse-gas control policies are not justified economically." Link

. Nobody is certain exactly what the consequences will be, but one distinct possibility is a cold period
; a previous low in solar activity, the Maunder minimum
, is correlated with a brief Little Ice Age
. Nobody really knows how this unusual solar weather pattern might interact with human-caused climate change. Previously

Right Wing astroturfing
A non-scientific analysis of the patterns in forum board discussions on a variety of topics. The gist: discussions of issues in which there's money at stake (like climate change
, public health
and corporate tax
avoidance) are often characterised by amazing levels of abuse and disruption by rightwing libertarians who are pro-corporate, anti-tax, anti-regulation. Discussions of issues in which there's little money at stake tend to be a lot more civilised than debates about issues where companies stand to lose or gain billions.

"...Arctic sea ice – frozen seawater that floats on the ocean surface – is now at its lowest physical extent ever recorded for the time of year, suggesting that it is on course to break the previous record low set in 2007.
Earth has been 0.65C warmer over the past 12 months than during the 1951 to 1980 mean, and that the global temperature for 2010 will exceed the 2005 record."

Odds of Cooking the Grandkids
: "There is a horrible paper in this week's Proceedings of the National Academy of Sciences, which looks at how the limits of human physiology interact with upper-range global warming scenarios. The bottom line conclusion is that there is a small - of order 5% - risk of global warming creating a situation in which a large fraction of the planet was uninhabitable (in the sense that if you were outside for an extended period during the hottest days of the year, even in the shade with wet clothing, you would die)."
