March Madness: Don’t Miss DeSmog UK’s Top Moments

We hit an exciting milestone in March with both our Facebook and Twitter pages reaching more than 1,000 followers. So, a big thank you is owed to everyone for liking and engaging with DeSmog UK!

Our top story caused quite the stir, to say the least. In a two-part exclusive interview with Michael Mann – dubbed his most intimate interview ever – we covered everything from American football and colour printers to Mann’s love of solving “important problems”.

With almost 4,000 pageviews between the two posts, and more than 200 shares on social media, we saw a global and varied readership. Michael Mann thought it was pretty great too, sharing it out on all his social media channels (cheers for that!).

How the Creation of Mann's Hockey Stick Led to a Climate Denier Counter-Attack

Our DeSmog UK epic history series continues with a look at the creation of Michael Mann’s hockey stick graph and the counter-attack launched by the climate deniers.

Michael Mann was “still relatively fresh” out of graduate school when his work demonstrating the rise in global temperatures caught the attention of senior climate scientists. He was quickly selected as lead author for a new report on climate change.

The paper by Mann, and Professor Raymond Bradley and Professor Malcolm Hughes was titled Global-Scale Temperature Patterns and Climate Forcing Over the Past Six Centuries. It introduced into the scientific literature what would soon become known as the ‘hockey stick’ graph.

This is When Hockey Stick Author Michael Mann First Realised the True Magnitude of Climate Change

In Part II of our intimate interview with Professor Michael Mann he tells of the exact moment he fully acknowledged humans were driving climate change – and how his conversion was thanks to the invention of the colour printer. Read Part I here. The interview forms part of our Epic History of climate denial. 

Michael Mann, the scientist behind the climate change hockey stick graph, began his PhD at the Department of Geology and Geophysics at Yale University under the supervision of Professor Barry Saltzman.

He remembers Saltzman as an “old fashioned scientist” who remained deeply sceptical about the latest claims being made by climate scientists that the atmosphere had begun warming and the future was bleak.

McIntyre's Mission: An Obsessive Quest to Disprove Michael Mann's Hockey Stick

There is no better way to describe self-appointed climate auditor Steve McIntyre than ‘determined’. Highly determined even.

And you would have to be pretty obstinate to try and poke holes in peer-reviewed climate science given that McIntyre claims he does not receive a salary signed by Big Oil. As author of the sceptic blog Climate Audit, all of McIntyre’s work is funded on his own dime.

Of course, his hotel accommodation while in London this August, where our interview was conducted, was paid for by Lord Lawson’s Global Warming Policy Foundation (GWPF).

I don’t have a big objection to think tanks sponsoring things … I don’t think there’s enough support for sceptics or critics as it is,” says the Ontario-based retired mining consultant whose blog inspired a hacker to break into servers at the University of East Anglia (UEA) and steal emails and data shared between the world’s leading global warming scientists.

Michael Mann's Opponents In Hockey Stick Defamation Case Regurgitate Half-Truths In New Court Filing

Michael Mann

Put up your hand if you’ve been a follower of news about climate change in recent years and haven’t heard of the “hockey stick” graph.

Nobody?  No, didn’t think so.

These graphs get their name because of their shape. 

They are reconstructions of the temperatures on Earth over several centuries to several millennia and they all have a repetitive tendency to turn sharply skyward showing the recent rapid warming of the Earth.

The most famous and first “hockey stick” came from research in the journal Nature in 1998 led by Professor Michael Mann, then of the University of Massachusetts Amherst.

Mann used historical data from tree rings and ice cores – known as “proxy records” - to determine what temperatures were like over the Northern Hemisphere over the 600 years or so before we had a reasonably well-dispersed network of thermometers.

When plotted on a chart… well, you know the rest.  It looked like a hockey stick.

Mann followed up that work in 1999, refining the research for a study in Geophysical Research Letters to give a full 1000-year history of the planet’s temperatures.

His work appeared in the 2001 United Nations Intergovernmental Panel on Climate Change report.  This is what it looked liked in that report (notice the red and blue colors - we'll come to that in a bit.)

Tax Breaks In Australia To Fund Climate Misinformation Book

It's amazing what qualifies for a tax break in Australia these days.

The climate science misinformation promotion unit at the Institute of Public Affairs, a Melbourne-based “free market” think tank, are currently passing the hat around to raise cash to publish a book on climate change.

The IPA has been pushing and promoting climate science denial since the late 1980s, when it published an article in its magazine asking if there really was a greenhouse effect.

According to an email to supporters earlier this month from the IPA’s executive director John Roskam, the think tank has raised $144,545 towards a $175,000 target to publish a book Climate Change: The Facts 2014.

Roskam reminded supporters that their donation for the book would be “tax deductible” and those prepared to part with $400 or more more would even get their name on the back cover.

The list of chapter authors is a predictable line up of denialists and contrarians picked from the blogosphere, conservative media outlets and the associates of secretly funded conservative think tanks.

They include Nigel Lawson, Stewart Franks, Bill Kininmonth, Mark Steyn, Donna Laframboise, Pat Michaels, Jennifer Marohasy, Andrew Bolt, Richard Lindzen, Jo Nova, Anthony Watts, James Delingpole, Bob Carter, Ross McKitrick and Ian Plimer.

Yep. A few Aussies will have slightly fatter tax refunds (or thinner bills) in exchange for funding climate science denialism and contrarianism from a list of usual suspects.

Is Organised Climate Science Denial Criminally Negligent?

By Lawrence Torcello, Rochester Institute of Technology. This article was originally published on The Conversation and is republished with permission.

The importance of clearly communicating science to the public should not be underestimated.

Accurately understanding our natural environment and sharing that information can be a matter of life or death.

When it comes to global warming, much of the public remains in denial about a set of facts that the majority of scientists clearly agree on. With such high stakes, an organised campaign funding misinformation ought to be considered criminally negligent.

The earthquake that rocked L'Aquila Italy in 2009 provides an interesting case study of botched communication. This natural disaster left more than 300 people dead and nearly 66,000 people homeless. In a strange turn of events six Italian scientists and a local defence minister were subsequently sentenced to six years in prison.

The ruling is popularly thought to have convicted scientists for failing to predict an earthquake. On the contrary, as risk assessment expert David Ropeik pointed out, the trial was actually about the failure of scientists to clearly communicate risks to the public. The convicted parties were accused of providing “inexact, incomplete and contradictory information”. As one citizen stated:

We all know that the earthquake could not be predicted, and that evacuation was not an option. All we wanted was clearer information on risks in order to make our choices.

Michael Mann: Canadians Should Fight Harper's War on Science and the U.S. Should Help

stephen harper

This is a guest post by distinguished climatologist Michael Mann. The article originally appeared on The Mark News.

The scientific community has long warned that environmental issues, especially climate change, need to be a global concern. Climatologist Michael Mann argues that Canadian Prime Minister Stephen Harper’s administration is purposely obstructing the research that needs to take place to solve these problems.

In early 2013, the government of Canadian Prime Minister Stephen Harper introduced new science communications procedures that threatened the publication rights of an American scientist who had been working in the Arctic with Canadian researchers since 2003.

This was the first time the Canadian government’s draconian confidentiality rules had infringed on the scientific freedom of an international academic – or, at least, it was the first time such an incident had been made known. Professor Andreas Muenchow from the University of Delaware publicly refused to sign a government agreement that threatened to “sign away [his] freedom to speak, publish, educate, learn and share.”

To many of us American scientists, this episode sadly came as little surprise. We have known for some time that the Canadian government has been silencing the voices of scientists speaking out on the threat of fossil-fuel extraction and burning and the damaging impacts they are having on our climate. I have close friends in the Canadian scientific community who say they have personally been subjected to these heavy-handed policies. Why? Because the implications of their research are inconvenient to the powerful fossil-fuel interests that seem to now run the Canadian government.

Why It's Not Enough To Be Right About Climate Change

Polar Vortex wind currents from earth.nullschool.net and the washington post

A couple weeks back, I found myself enmeshed briefly in a local debate here in Calgary regarding the validity of the argument that a continent-wide spell of frigid weather raised a serious challenge to the scientific foundations of anthropogenic climate change. In the depths of the cold snap, a rookie city councillor, Sean Chu, tweeted:

I replied:

The exchange and other snarky dismissals of Chu’s line of reasoning got picked up by the Calgary Herald, which ran a news item on its blog and a follow-up piece defending Chu against “anthropogenic global warming religionists” on the op-ed page.

As we were engaged in our local rhetorical joust, climate change deniers continent-wide were re-enacting the same little drama on stages big and small, eventually inspiring one of those killer rapid-fire round-ups of TV news talking-head idiocy on The Daily Show with Jon Stewart. “Apparently decades of peer reviewed study can be, like a ficus plant, destroyed in one cold weekend,” Stewart concluded.

In itself, any given one of these minor foofaraws (or are they argle-bargles?) is barely worth wasting the pixels contained in this sentence. But as a whole — as a tenaciously consistent, recurring pattern of discourse — they actually illustrate a singular challenge to concerted and sustained climate change action. So if you’ll stick with me, let’s unpack the mess a bit and take a look.

Judge Denies National Review's Motion to Reconsider Ruling in Michael Mann's Defamation Case

Cross-posted with permission from Climate Science Watch.

“The Court finds that there is sufficient evidence in the record to demonstrate that Plaintiff is likely to succeed on the merits,” said a DC Superior Court judge in her latest procedural ruling in the defamation case of Michael Mann v. National Review, et al. “The evidence before the Court indicates the likelihood that 'actual malice' is present in the [National Review's] conduct.” 

On August 30 the Court denied the Defendants' Motion for Reconsideration of the Court's July 19 order, which had affirmed Prof. Mann's right to proceed in his defamation lawsuit. The text of the August 30 Court Order is here in PDF.

Some excerpts from the Court Order denying Defendants' Motion for Reconsideration:
