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)."

The University of East Anglia's Climatic Research Unit
suffered a security breach
this week. Hackers made off with thousands of email correspondences between some of the world's top climate scientists, and posted them to the Internet1
Tony Hake has posted an article
at The Examiner, highlighting what he feels are the most egregious examples of scientists manipulating and hiding data to support the established theories about Climate Change. Some of the scientists involved counter
that the quotes are taken out of context, and that "People are using language used in science and interpreting it in a completely different way".

The Polar Discovery
team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions
. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through photo essays
and other multimedia
, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at WHOI

Most people have heard about how rising CO2 levels are resulting in a changing global climate.
Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "Ocean Acidification
". This changing ocean chemistry has many important and devastating consequences. [more inside]

From these various anthropological approaches, a basic dichotomy has emerged between two types of societies from very different ecosystems: societies born in rain forests and those that thrive in deserts....
Begin with religious beliefs. A striking proportion of rain forest dwellers are polytheistic, worshipping an array of spirits and gods.... But desert dwellers... are usually monotheistic. Of course, despite allegiances to a single deity, other supernatural beings may be involved, like angels and djinns and Satan. But the hierarchy is notable, with minor deities subservient to the Omnipotent One. This division makes ecological sense.... Desert societies, with their far-flung members tending goats and camels, are classic spawning grounds for warrior classes and the accessories of militarism.... Rain forest cultures also are less likely to harbor beliefs about the inferiority of women; you won’t be likely to find rain forest men giving thanks in prayer that they were not created female, as is the case in at least one notable desert-derived religion....

potholer54 is a youtuber who in his own words; I've been a journalist for 20 years, 14 years as a science correspondent. My degree is in geology, but while working for a science magazine and several science programs I had to tackle a number of different fields, from quantum physics to microbiology.
He has a series called Climate Change

The Future Generator
at the London Transport Museum
is a forecasting look at the effect of transport on climate change in London. But you can get a sense of history as well. The museum's collection originated in the 1920s, when the London General Omnibus Company decided to preserve two Victorian horse buses and an early motorbus for future generations. They moved to the present location in 1980. Londoners can take a trip back in time
on the Metropolitan line and enjoy a special day out in Metro-land as two historic electric trains run special excursions on Sunday 14 September 2008. [more inside]

The draft Garnaut Climate Change Review
was released last Friday. This is the most comprehensive look so far at the economic implications of climate change and emissions trading for a developed country (Australia). Essential (but weighty) reading for those interested in the economics of the issue, a useful localisation of Stern

In 1987, the Caltech biomagnetist and paleomagnetist Joe Kirschvink gave undergraduate Dawn Sumner a rock sample [from South Australia] to study for her senior thesis.
The apparent glacial origin of this rock lead directly to the theory that periodically the Earth has been thoroughly glaciated from the poles to the Equator: the so-called Snowball Earth
events. A website
dedicated to this theory includes detailed teaching slides
, a FAQ
, and many other resources on this interesting period in Earth's history.
