Twelve climate scientists and contrarians recently had dinner together in the UK, which for some reason received media attention. While everyone should be free to have dinner with whomever they like, the problem with this particular event was that the ensuing media coverage made the contrarians seem downright reasonable. For example, the article about the dinner stated,
Yet one of the contrarians attending the dinner was Anthony Watts, who runs a blog that regularly insults climate scientists and climate realists. In fact, just a few days after the dinner, Watts was already taunting Ben Santer, one of the world’s most highly respected climate scientists, who had previously treated Watts with courtesy and respect. The article also quoted Watts as saying,
Climate contrarians are already free to present science at climate conferences. For example, the annual American Geophysical Union (AGU) fall meeting is the largest gathering of climate scientists presenting and discussing their research. Every year, the vast majority of scientific research presented at the AGU conference and others like it (about 97% or so) is consistent with the expert consensus on human-caused global warming. Contrarians don’t present science there because they have so little science to present.
The Mail on Sunday’s David Rose also attended the dinner. His latest climate article focused on the slight increase in Arctic sea ice as compared to the record low of two years ago (and of course on Al Gore), while ignoring the fact that the Arctic has lost about 70% of its total volume of sea ice over the past three decades.

DeSmog UK has found that libertarian banker Lord Leach is a likely funder of the anti-climate political advocacy group Global Warming Policy Foundation (GWPF). In May of 2009, Lord Leach gave a long speech in Parliament detailing his beliefs about global warming.
The speech was full of inaccuracies, myths, and misinformation. Known as a Gish Gallop, the sheer number of false claims in the speech would require tremendous effort to debunk. Most telling were the sources that Lord Leach relied upon to support his statements. For example,
While Richard Lindzen is a climate scientist, he’s also the climate scientist who’s been the wrongest, longest. Throughout his climate science career, Lindzen consistently took positions that were contrary to the climate science mainstream. For example, Lindzen claimed that global warming over the 20th century was minimal, that humans have an insignificant impact on global temperatures, and that water vapor will act to dampen global warming. All of these claims and many more have proven to be completely wrong. In another contrarian position, Lindzen has disputed the link between secondhand smoke and lung cancer.

The Cornwall Alliance for the Stewardship of Creation is a conservative evangelical Christian public policy group that promotes a free-market approach to protecting the environment. The organization recently published a list of ten reasons it opposes policies to reduce carbon pollution and slow global warming, purportedly to protect the poor. As the first point on the list illustrates, the group essentially believes that the Earth’s climate will be able to correct any damage done by humans.
The group includes climate scientist Roy Spencer and professor of geography David Legates. Spencer’s research is among the 2–3% of peer-reviewed climate papers disputing that humans are the main cause of global warming. He has often argued that climate policies will harm the poor, and has not been shy in making political and free market statements, having gone as far as to make comments about “global warming Nazis.” Legates is known for disputing the 97% expert consensus on human-caused global warming.
The Cornwall Alliance has tried to use scientific arguments to support its religious beliefs about the resiliency of the global climate, claiming,

As has become the norm for media outlets owned by Rupert Murdoch, just before a half million people participated in the People’s Climate March around the world, The Wall Street Journal published an opinion piece downplaying the risks and threats posed by human-caused global warming. The editorial was written by Steven Koonin, a respected computational physicist who claims to have engaged in “Detailed technical discussions during the past year with leading climate scientists,” but who is himself not a climate scientist.
Koonin did admit that the climate is changing and humans are largely responsible, and noted,
This is a step in the right direction. Unfortunately, Koonin’s editorial focused almost exclusively on the remaining uncertainties in climate science. Ironically, he stated,

The Canadian government is hell-bent on exploiting the Alberta tar sands to the fullest extent possible, even at the expense of the global climate. Canada simply cannot meet its carbon pollution reduction pledges if it continues to expand tar sands operations.
While the American government has finally begun to take the threat of climate change seriously and do something about it, the Canadian government has merely played lip service to the problem. 50 Canadian climate researchers have reached the point where they feel the need to speak out, using the People’s Climate March on September 21st as a catalyst to call for action. To that end, they penned the following letter.

A pair of climate scientists recently had a dispute regarding how much global warming humans are responsible for. Gavin Schmidt from Nasa represented the consensus of 96–97% of climate experts in arguing that humans have been the dominant cause of global warming since 1950, while Judith Curry from Georgia Tech represented the opinions of 2–4% of climate experts that we could be responsible for less than half of that warming.
Curry is to be the featured speaker on this subject at a National Press Club event tomorrow hosted by the Marshall Institute; a right-wing thinktank that has spread misinformation about the dangers of smoking, ozone depletion, acid rain, DDT, and now climate change. She may also discuss the subject at an event next week hosted by the fossil fuel-funded right-wing think tank Texas Public Policy Foundation (TPPF).
The exchange between Schmidt and Curry can be read on RealClimate – a blog run by climate scientists. The discrepancy in both the quantity and quality of the supporting evidence used by each scientist was one of the most telling aspects of their debate.
For his part, Schmidt referenced the most recent IPCC report. The IPCC summarises the latest and greatest climate science research, so there is no better single source. The figure below from the IPCC report illustrates why 96–97% of climate science experts and peer-reviewed research agree that humans are the main cause of global warming.
The black bar indicates the amount of global surface warming observed from 1951 to 2010. The green bar shows the amount of warming caused by human greenhouse gas emissions during that time. The yellow is the influence from other human effects (mainly cooling from human sulfate aerosol emissions, which scatter sunlight), and the orange is the combined human effect. Below those are the contributions from external natural factors (mainly the sun and volcanoes) and from natural internal variability (mainly ocean cycles), while the whiskers show the uncertainty range for each.

Connecting the dots between human-caused global warming and specific extreme weather events has been a challenge for climate scientists, but recent research has made significant advances in this area. Links have been found between some very damaging extreme weather events and climate change.
For example, research has shown that a “dipole” has formed in the atmosphere over North America, with a high pressure ridge off the west coast, and a low pressure trough over the central and eastern portion of the continent.
These sorts of pressure ridges in the atmosphere are linked to “waves” in the jet stream. Research has shown that when these jet stream waves form, they’re accompanied by more intense extreme weather. The high pressure zone off the west coast or North America has been termed the “Ridiculously Resilient Ridge” due to its persistence over the past two years. It’s been the main cause of California’s intense drought by pushing rain storms around the state.

Although the global climate has continued to build up heat at an incredibly rapid rate, there has been a keen focus among climate contrarians and in the media on the slowdown of the warming at the Earth’s surface. The slowdown is in fact a double cherry pick – it focuses only on the 2% of global warming that heats the atmosphere (over 90% heats the oceans), and it only considers the past 10–15 years. Nevertheless, because there was so much attention paid to the surface warming slowdown, the latest IPCC report addressed it specifically, saying,
From 1998 through 2012, the Met Office estimated that global surface temperatures had warmed by about 0.06°C, whereas the average climate model projection put the value at closer to 0.3°C. This apparent discrepancy only represented a tiny fraction of overall global warming, and over a short enough period of time that the internal noise of the climate system could be having a significant influence, but it was nevertheless a challenge for climate scientists to explain the precise causes of the difference.

As people’s understanding of climate science grows, among both experts and non-experts alike, we become more accepting of the fact that humans are the driving force behind global warming. That’s because the evidence supporting human-caused global warming is overwhelming; hence rejection of that reality is usually based on an incomplete understanding of the scientific evidence.
In Australia, Prime Minister Tony Abbott’s chief business adviser Maurice Newman offered a prime example of global warming denial last week. Writing in The Australian, Newman suggested that we’re headed for a period of global cooling due to declining solar activity and related influences from galactic cosmic rays, calling mainstream climate science “a religion.”
As Graham Readfearn showed in his fact check of The Australian opinion piece, Newman got the science badly wrong in almost every way imaginable. Scientific research has consistently shown that a grand solar minimum would barely make a dent in human-caused global warming, and that galactic cosmic rays do not exert a significant influence on the Earth’s climate. To argue otherwise, Newman relied on selective cherry picking of some research, and a misinterpretation of other studies.

A new study led by Bart Verheggen surveyed 1,868 scientists studying various aspects of climate change, asking them several questions mainly focused on what’s causing global warming. They survey also asked the respondents,
The answers to this question reflect whether the media is really fair and balanced on the subject of global warming. A truly balanced media would give equally proportional attention and coverage to climate scientists in the mainstream and on the fringes. For example, if 20% of contrarian climate scientists reported frequent media attention, a fair and balanced media would also give frequent coverage to 20% of mainstream climate scientists.
Instead, fringe contrarian climate scientists reported that they receive frequent media coverage twice as often as mainstream climate scientists.
