There is a war under way for control of the Internet, and every day brings word of new clashes on a shifting and widening battlefront. Governments, corporations, criminals, anarchists—they all have their own war aims.

[O]ur notion of software quality with respect to climate models is theoretically and conceptually vague. It is not clear to us what differentiates high from low quality software; nor is it clear which aspects of the models or modelling processes we might reliably look to make to that assessment.

Global warming in the coming years will foster trauma, depression, violence, alienation, substance abuse, suicide, psychotic episodes, post traumatic stress disorder and many other mental health-related conditions.

Conservationists need to work with development, not condemn it as leading to the end of nature. In truth, nature’s resilience has been overlooked, its fragility “grossly overstated.” Areas blasted by nuclear radiation are bio-diverse. Forest cover is rising in the Northern Hemisphere even as it declines globally.

If Booth and colleagues’ results can be corroborated, then they suggest that multidecadal temperature fluctuations of the North Atlantic are dominated by human activity, with natural variability taking a secondary role. This has many implications. Foremost among them is that the AMO does not exist, in the sense that the temperature variations concerned are neither intrinsically oscillatory nor purely multidecadal.

In recent weeks, we are seeing two very interesting debates, both of which involve Richard Lindzen. The first debate involves the recent WSJ op-ed No Need to Panic About Global Warming. The second involves Lindzen’s seminar at the House of Commons.
Lets take a look at the latest response and parries in these ongoing debates.

In political debates that involve considerations of science, it is tempting to characterize scientists who demand particular types of action simply as political partisans. But when scientists make demands of the political process there is often more going on than just an effort to achieve political gain for one’s preferred policies.

Nature’s exuberant smashing of daily high temperature records [in the U.S.] in recent weeks can only be described as “Meteorological March Madness”. Conditions more fitting of June than March prevailed east of the Rocky Mountains since the start of the month. NOAA’s National Climate Data Center reported that over 7000 daily record high temperatures were broken over the U.S. from 1 March thru 27 March.

“It’s a national embarrassment. It has resulted in large unnecessary costs for the U.S. economy and needless endangerment of our citizens. And it shouldn’t be occurring.
What am I talking about? The third rate status of numerical weather prediction in the U.S. It is a huge story, an important story, but one the media has not touched, probably from lack of familiarity with a highly technical subject. And the truth has been buried or unavailable to those not intimately involved in the U.S. weather prediction enterprise.” — Cliff Mass, UW

Multiple choice test: Republicans are more skeptical than Democrats about climate change because:
a) A defensive ideology is hardwired into their brain
b) A growing distrust of scientific institutions because of the politicization of science

The Obama administration proposed on Tuesday the first ever standards to cut carbon dioxide emissions from new power plants, a move likely to be hotly contested by Republicans and industry in an election year.

The need for policy makers to understand science and for scientists to understand policy processes is widely recognised. However, the science-policy relationship is sometimes difficult and occasionally dysfunctional; it is also increasingly visible, because it must deal with contentious issues, or itself becomes a matter of public controversy, or both. We suggest that identifying key unanswered questions on the relationship between science and policy will catalyse and focus research in this field.

Here is a recent example of artful lack of disclosure in the climate change debate, on the possible negative impacts of climate change on food security.

THE LIGHTS ARE not going off all over Japan, but the nuclear power plants are. Of the 54 reactors in those plants, with a combined capacity of 47.5 gigawatts (GW, a thousand megawatts), only two are operating today. A good dozen are unlikely ever to reopen . . . (from the Economist)

Climate science is sometimes characterized by skeptics as pseudoscience. Here are the arguments for why climate science is not pseudoscience.

**UPDATE at end of thread**
The effect of the adjustments introduced in Met. Office’s HadSST3 release are compared to the original ICOADS data to evaluate their effects on the frequency content of the data. The relative merits of making a simple adjustment for the war-time glitch in ICOADS are also investigated. It is demonstrated that the various adjustments made in preparing Hadley SST versions combine to effectively removing long term variations from the climate record. Frequency analysis shows the adjustments generally disrupting, rather than improving the data.

In late February, Sir Paul Nurse, president of the Royal Society, gave the Dimbleby Lecture for the BBC. There are some good statements in his address, but here I focus on his statements about the relationship between science and society.

During the 20th century, solar activity increased in magnitude to a so-called grand maximum. It is probable that this high level of solar activity is at or near its end. It is of great interest whether any future reduction in solar activity could have a significant impact on climate that could partially offset the projected anthropogenic warming. (Jones et al. 2012).

In principle, yes of course. In practice, many journalists, scientists and government officials are not so certain as to how to balance telling the whole truth and being truthful in an “effective” way.
