We have had some extreme conditions the last few years – of cold, heat, snow and rain. Detailed summaries on the cold last winter can be found here and on the hot summer here. Both were memorable seasons indeed. Though the second author did an excellent job detailing the summer records and did mention the amplified and frozen jet stream, he went on to say man made global warming contributed to it.

Whereas the media and alarmists like to portray extremes (Holdren has called it “Climate Disruption”) as the result of or greatly amplified by man made greenhouse gases, natural factors can be shown as the cause. Too many scientists and media ‘enviro’ bloggers have stated “it must be man-made – what else could it be?”

Abstract: Perlwitz etal (2009) used computer model suites to contend that the 2008 North American cooling was naturally induced as a result of the continent’s sensitivity to widespread cooling of the tropical (La Nina) and northeastern Pacific sea surface temperatures. But they concluded from their models that warming is likely to resume in coming years and that climate is unlikely to embark upon a prolonged period of cooling. We here show how their models fail to recognize the multidecadal behavior of sea surface temperatures in the Pacific Basin, which determines the frequency of El Ninos and La Ninas and suggests that the cooling will likely continue for several decades. We show how this will be reinforced with multidecadal shift in the Atlantic.

Arctic stations near heat sources show warming over the last century. Arctic stations that are isolated from manmade heat sources show no warming.

News broke on or around 19 November 2009 that a large archive of emails and files from the Climatic Research Unit (CRU) in the UK had been released on the internet. The contents of the files were sufficiently disconcerting to the public, governments and university administrations that a number of inquiries were established. Several of my research projects were discussed not only in the so-called “Climategate” emails themselves, but also in the investigations, and I made detailed submissions of evidence to three of the panels. Consequently I take considerable interest in the outcome of these inquiries, especially with regards to whether they approached the issues impartially, investigated thoroughly and drew valid conclusions that fully reflected the evidence.

Even with all of the recent scandal surrounding the purveyors of climate change pap, many in the “news media” continue to crank out party-line articles blaming all of Earth's ecological woes on humanity. After decades of trying to alarm the public over a human caused “sixth mass extinction” and more recently, dwindling diversity, some in the media just can't let go of AGW as the root of all evil.

Readers who are familiar with the various issues will recognize that the Deutsche Bank (DB) report is one-sided. The weakness of its argumentation is partly due to its failure to properly quote the material it purports to rebut, so that its arguments are frequently shallow and unconvincing. In this rejoinder I will focus only on two items: The Hockey Stick controversy and the report’s treatment of the “Hide the Decline” email. These should suffice to illustrate the weakness of the DB report.

Recent reports claim June was the warmest on record, but it seems to fly in the face of reports of record cold from around the world.

The leaking of the East Anglia “Climategate” e-mails and data last November shattered the appearance of a scientific consensus on supposed “man-made global warming” and provided a disturbing insight into the corruption of the scientific process as it relates to the “man-made global warming” hypothesis. The spectacle of scientists stonewalling freedom of information requests, destroying records, hiding unwelcome results, colluding to keep dissenting viewpoints out of scholarly journals, and even suppressing their own acknowledged doubts — all of this made it perfectly clear that other interests were at stake than the pure pursuit of knowledge. The centrality of the quest for funding in the e-mail exchanges made it equally clear that for the scientists in question, money, unsurprisingly, was first and foremost among those interests.
