A very anti-American act

But so many of Obama's appointments were America-haters, it is just part of his pattern. Raising fuel economy standards will hurt American car manufacturers only, principally Ford. The new GM can just suck on the taxpayer teat like the hungry baby it is (Note: "more federal support for the development of new-generation cars") -- and Chrysler has been a basket-case for years. Japanese manufacturers are already focused on the fuel-sipping end of the market so they probably won't have to change a thing.

And the only way to meet the standards is to get all passenger car-drivers into smaller, lighter, flimsier cars. The heavy truck fleet will always use lots of fuel. It takes lots of fuel to move heavy loads and nothing will change that. And smaller, lighter, flimsier cars will kill more Americans in road accidents. What's not to like about that for an America-hating President of Muslim origins?

But it's mostly blue sky anyway. His new dictates won't take effect until he is out of office. And even a week is a long time in politics

But what would it mean if it all went into effect? Probably no more 18-wheelers and no more SUVs. Wouldn't that give Greenies a horn?

President Obama has decided to use his executive power to order tougher fuel efficiency standards for cars and trucks, accelerating the fight against climate change without waiting for Congress, administration officials said Thursday.

Mr. Obama plans to announce on Friday that he is ordering the creation of a new national policy that will result in less greenhouse-gas pollution from medium- and heavy-duty trucks for the first time and will further reduce exhaust from cars and light-duty trucks beyond the requirements he has already put in place.

Under rules that were eventually formalized last month, new cars have to meet a combined city and highway fuel economy average of 35.5 miles per gallon by 2016. The administration said the new rules would cut emissions of carbon dioxide and other heat-trapping gases by about 30 percent from 2012 to 2016.

The plan Mr. Obama will announce on Friday will order further improvements in fuel efficiency for cars and light trucks made in 2017 and beyond, and in medium and heavy trucks made in 2014 through 2018.

The initiative comes as the spill in the Gulf of Mexico has underscored the problem with dependence on oil, and officials said the president would cite the problem when he discusses his plan. The order allows Mr. Obama to advance his goals even as Senate Democrats have difficulty trying to pass a comprehensive energy bill that he supports.

Administration officials confirmed the plan after disclosing it to environmental advocates but insisted on anonymity to avoid upstaging the announcement. In addition to the fuel efficiency and pollution standards, Mr. Obama’s directive will order more federal support for the development of new-generation cars like advanced electric vehicles and will instruct the Environmental Protection Agency to reduce pollutants from motor vehicles other than greenhouse gases.

Environmentalists hailed the move. “President Obama’s oil savings proposal will reduce our dependence on oil,” said Daniel J. Weiss, director of climate strategy at the Center for American Progress, a liberal research organization. “More efficient cars and trucks will help to protect families’ budgets as well as America’s shores.”

Medium and heavy trucks represent only 4 percent of all vehicles on American highways but they consume more than 20 percent of on-road transportation fuels, according to the Union of Concerned Scientists, an environmental advocacy organization. Improving the average fuel economy of these trucks by 3.7 miles per gallon would reduce American annual oil consumption by 11 billion gallons in 2030, the group said.

Building cleaner cars costs money but may ultimately save consumers more through lower gasoline bills. The policy already enacted will add about $1,000 to the cost of an average new car by 2016, but save about $3,000 in fuel over the life of the vehicle, according to government officials.

The president will be joined Friday by environmental leaders as well as representatives of major automakers and truck manufacturers supporting the new policy, administration officials said. The Transportation Department and the Environmental Protection Agency will jointly develop the policy.

Manufacturers want a single, national standard set over the long term because it is easier to meet than the patchwork quilt of regulations imposed in the past.

Before the president’s initial policy a year ago, car and light-truck makers were facing fuel-efficiency standards being developed by the National Highway Traffic Safety Administration in response to Congressional legislation, separate greenhouse gas standards being developed by the Environmental Protection Agency under the Clean Air Act and the possibility of separate standards enacted in California and 13 other states.

Global Warming’s $64 Trillion Question

Despite its relative simplicity, I continue to find myself trying to explain to experts and lay persons alike how scientists made the Great Global Warming Blunder when it comes to predictions of global warming.

On the bright side, this morning I received an e-mail from a chemist who looked at the math of the problem after reading my new book, and then came to the understanding on his own. And that’s great!

For the most part, though, the climate community continues to suffer from a mental block when it comes to the true role of clouds in global warming. All climate models now change clouds with CO2 warming in ways that amplify that warming, some by a catastrophic amount.

As my latest book describes, I contend that they have been fooled by Mother Nature, and that in fact warming alters clouds in ways that mitigate – not amplify — the small amount of direct warming caused by increasing atmospheric CO2.

The difference between clouds magnifying versus mitigating warming could be the difference between global warming being little more than an academic curiosity…or a disaster for life on Earth.

So, once again I find myself trying to explain a concept that I find the public understands better than the climate experts do: when it comes to clouds and temperature, the direction of causation really does matter.

Why Are There Fewer Clouds when it is Warm?

The “scientific consensus” has been that, because unusually warm conditions are observed to be accompanied by less cloud cover, warming obviously causes cloud cover to decrease. This would be bad news, since decreasing cloud cover in response to warming would let more sunlight in, and amplify the initial warming. That’s called positive cloud feedback.

But what they have difficulty understanding is that causation in the opposite direction (cloud changes causing temperature changes) gives the ILLUSION of positive cloud feedback. It turns out that, when less cloud cover causes warmer temperatures, the cloud feedback in response to that warming is almost totally obscured.

Believe it, the experts have not accounted for this effect. I find it bizarre that most are not even aware it is an issue! As far as I know, I am the only one actively researching the issue.

As a result, the experts have fooled themselves into believing cloud feedbacks are positive. We have demonstrated theoretically in our new paper now accepted for publication in JGR that, even if strong negative cloud feedback exists, cloud changes causing temperature change will make it LOOK like positive cloud feedback.

And this indeed happens in the real climate system. The only time cloud feedback can be clearly seen in the real climate system is when temperature changes are caused by something other than clouds. And in those cases, we find that the net feedback is strongly negative (around 6 Watts per sq. meter of extra energy lost by the Earth per deg. C of global-average warming).

Unfortunately, those events only occur on relatively short climate time scales: 1 month or so. Whether this negative feedback also exists for long-term climate warming is less certain.

Do Climate Models Agree With Satellite Observations of Clouds and Temperature?

The fact that all the climate models which produce substantial global warming also approximate what we measure from satellites is NOT a validation of the feedbacks in those models. So far, after analyzing thousands of years of climate model runs, I have found no convincing way to validate the climate models’ long-term feedbacks with short-term (approx. 10 years or so) satellite observations. The reason is the same: all models have cloud variations causing temperature variations, which then obscures the feedback we are trying to measure.

But there’s another test that could be made. The modelers’ case would be stronger if they could demonstrate that 20 additional climate models, all with various amounts of negative – rather than positive — cloud feedback, are less consistent with our satellite observations than the current crop of models, all of which had positive cloud feedback.

I suspect they do not spend much time on that possibility. A climate model that does not produce much climate change is going to have difficult time getting continued funding for its support.

Trivia Question to Illustrate the Point: Assume continually increasing CO2 in the atmosphere is the only source of climate variability, and we experience continuous slow warming as a result. Will the outgoing longwave radiation (OLR, or infrared) being emitted by the Earth increase…or decrease…during this process?

ANSWER: If warming is the result of increasing CO2 in the atmosphere, then the outgoing longwave radiation (OLR) from the Earth will DECREASE over time. As scientists already know, it is this decrease in OLR that causes the warming in the first place. But because the climate system cannot warm instantly in response (there is a time lag due to the heat capacity of land, ocean, and atmosphere), the increased OLR from warming can never fully make up for the decrease in OLR causing the warming. That warming-induced increase represents the FEEDBACK RESPONSE. But it is forever more than offset by the FORCING from increasing CO2.

Now, If we know the time-history of the forcing, it can be subtracted from the OLR to get the feedback. Indeed, this is how feedbacks are diagnosed from climate model experiments involving transient CO2 forcing. The “blunder” I talk about refers to the fact that climate researchers have not accounted for natural sources of radiative forcing (cloud variations) in their attempts to diagnose feedback in the real climate system.

Technical Note: We have found from modeling studies that if the natural cloud variations were truly random in time, the error in diagnosed feedback would be random, not biased toward positive feedback, and would average out to near zero in the long term. But in the real climate system, these cloud variations have preferred time scales….in other words, they have some degree of autocorrelation in time. When that happens, there ends up being a bias in the direction of positive feedback.

American Physical Society slowly backing away from manmade global warming

The Council of the American Physical Society (APS) has adopted on April 18, 2010 a "Climate Change Commentary" to append to their definitive and "incontrovertible" 2007 policy statement on climate change. The commentary allows considerable backpedaling from the prior policy while appearing to save face.

The commentary removes the word incontrovertible because such words are "rarely used in science because by its very nature science questions prevailing ideas." The statement "While there are factors driving the natural variability of climate (e.g., volcanoes, solar variability, oceanic oscillations), no known natural mechanisms have been proposed that explain all of the observed warming in the past century." is added, and while not true since there are a number of papers which show that ocean oscillations and solar variability can explain all of the 0.7 degree warming of the past century, it is a step in the right direction from the 2007 policy which makes no mention of natural forcing and blames climate change on man-made emissions of CO2.

For the first time there is acknowledgement of the uncertainties associated with models, including the statement "These models have uncertainties associated with radiative response functions, especially clouds and water vapor. However, the models show that water vapor has a net positive feedback effect (in addition to CO2 and other gases) on global temperatures. The impact of clouds is less certain because of their dual role as scatterers of incoming solar radiation and as greenhouse contributors." While it is true the models show net positive feedback, that is only because that is how they were programmed, and no mention is made of the empirical satellite and weather balloon data which show the net feedback is actually negative. At least, the commentary begins to indicate large uncertainties with climate modeling.

The commentary adds "The uncertainty in the estimates from various climate models for doubling CO2-equivalent concentration is in the range of 1°C to 3°C with the probability distributions having long tails out to much larger temperature changes.", without mentioning that 1°C global warming is what is expected from the no feedback model and even less from the negative feedback model as supported by data, which is likely to be beneficial and is hardly cause for alarm or cap & tax schemes.

As Richard Lindzen and Roy Spencer have repeatedly pointed out, the real issue to be determined is the sensitivity of the climate to changes in CO2, for which all the empirical data show the models have greatly overestimated sensitivity. If there is low sensitivity, there is no cause for alarm.

Nuclear Power Now Back in Vogue Thanks to the Left's Political Miscalculations (?)

Political miscalculations on the part of global warming alarmists have opened the way for a renewed commitment to nuclear power that will find expression within the next few years, Joe Bast, president and CEO of the Heartland Institute observed just as his organization’s fourth International Conference on Climate Change concluded.

The growing “climategate” scandal that involves emails leaked to the Internet from the Climate Research Unit (CRU) of the University of East Anglia in Great Britain has confirmed the skeptical view of man-made global warming theories and “put a stake in the heart” of the pseudoscience that fuels alarmism, Bast said in an interview on the final day of the conference in Chicago, Illinois.

As an added benefit, he expects U.S. policymakers to divorce themselves from “cap and trade” schemes and to move more forcefully in the direction of sensible energy polices, especially after the November elections.

“I think one unintended consequence of this whole debate has been the re-examination and re-legitimization of nuclear energy,” Bast suggested. “I’m sure the left must be kicking itself for allowing this to happen. They should have thought ahead and asked themselves what would happen if they lost on global warming. As it turns out, they have helped to endorse and validate nuclear power. You are going to see a lot more nuke plants built over the next 20 to 30 years.”
Some of the key developments that occurred in the climate debate since last Heartland Conference in Washington D.C. are as follows:

• Last November, emails and other documents from the Climatic Research Unit at the University of East Anglia revealed a pattern of mismanagement of temperature data, interference with peer review, and overt efforts to suppress academic debate on global warming;

• In December, negotiations in Copenhagen over a successor to the Kyoto Protocol collapsed, leaving the world without a binding international agreement after Kyoto expires in 2012;

• In January, major errors of fact and forecasts in the reports of the Intergovernmental Panel on Climate Change (IPCC) were acknowledged by the agency’s staff and supporters;

• In February, Phil Jones, director of the Climatic Research Unit, admitted there has been no statistically significant global warming since 1995 and that “the vast majority of climate scientists” do not believe the debate on climate change is over;

• In March and April, The Christian Science Monitor and many other respected sources uncovered evidence of massive fraud in the operation of cap-and-trade programs, raising doubts about the workability of such programs as well as the ethics and objectivity of Al Gore and others who have made millions of dollars by creating firms that buy and sell carbon credits.

Despite a growing body of scientific evidence that points to natural as opposed to man-made factors that fuel warming and cooling cycles, Sen. John Kerry (D-Mass.) and Sen. Joe Lieberman (I-Conn.) introduced a repacked version of “cap and trade” earlier this month that would impose carbon reductions on industry. However, Bast does not expect the legislation to gain any traction in the U.S. Senate.

“Cap and trade is dead,” he said. “We are finally on the downhill here, we are victors. Now is agreat time to be a skeptic, now is a great time to be a libertarian. The vibe at this conference was fantastic.”

Green versus Green in Britain

Apparently there are at least some Greens who don't like hypocrisy

A decision by a climate-change group to fly leading activists 12,000 miles to a conference threatens to tear the movement apart. The leadership of Climate Camp – which is opposed to flying and airport expansion – have been accused of hypocrisy after they sent two members on a £1,200 round-trip to Bolivia.

The leaders argued it was necessary to attend the ‘transnational protest’ – even though the flights generated eight tons of carbon dioxide greenhouse gases.

Now a furious backlash against the trip threatens to split the group, which in the past has blockaded Heathrow airport and clashed with police at demonstrations against coal-fired power stations. A memo circulated to Climate Camp members claimed the group had been taken over by a ‘clique’ who were manipulating its work. The note claimed ‘the same small group controls all aspects’ of the movement and that a ‘stagnant culture’ ensured the ‘same people always filled the same roles’.

One activist wrote on the group’s Facebook page: ‘If you believe flying halfway around the world is a necessary mission for Climate Camp, I feel you are sadly deluded.’ She added: ‘It is an absolute disgrace that any Climate Camper would even think about going by air.’ [swim?]

The activist later submitted a formal complaint to the group. She said: ‘There was no due process in permitting two Climate Campers to travel to Bolivia by plane. 'There was little discussion on the mode of transport to be used and no consensus to permit it.’

The complaint provoked a furious backlash from Ben Hart, one of the activists who flew to Bolivia. In a series of postings on Facebook under the pseudonym Gringo Ben, he lashed out at opponents of the trip. He wrote: ‘Get over it, if you wanna play this liberal self-denial game...I’ve been vegan for 17 years of my life and gone many years without a car. ‘If I died tomorrow and didn’t take my return flight or any others in the future, the planet would still be being ruined.’

He added: ‘You seem to think Climate Camp is, or should be, purist, but the Camp is not dogmatic but actually quite pragmatic when it comes to the compromises necessary to engage in campaigning. ‘It’s bang out of order to point a finger at us in this way and question our role in the Camp. It was a Camp decision, good or bad.’

Climate Camp describes itself as a grassroots movement and is supposedly controlled by its membership at regular meetings.

But the group of angry members claim they are ‘disillusioned with the process’ and that ‘it is alienating new attendees and undermining the motivation and commitment to the movement’.

They said in their memo: ‘The hierarchical culture that is forming is dishonest and is in contradiction of our non-hierarchical principles and aspirations.’

Canadian Warmists clutching at straws

Tom Pederson, director of British Columbia’s Pacific Institute for Climate Solutions, got some cheap laughs at the expense of Rex Murphy and Murphy’s journalistic reputation at a University of Victoria panel on climate and the media in April.

The panel members were Pederson, Lucinda Chodan, editor of the Victoria Times Colonist, Peter Calamai, a science journalist, and James Hoggan, author Climate Cover-up, which claims that unscrupulous right-wing think tanks are trying to brainwash the public against belief in global warming. There was, thanks to Pederson (see why below), no one representing the skeptical side of the issue.

In his 15-minute segment, Pederson accused Murphy of breaching journalistic ethics in a July 24, 2009, Globe and Mail column entitled “So where’s that global cooling alert?” Murphy’s crime? He ignored what Pederson considers the global warming “facts.” Pederson’s point was that a newspaper columnist can have whatever opinions he/she wants, but these opinions must be based on facts, not just ideology. As a former columnist myself, for the Times Colonist, I also believe this is true.

Murphy’s column noted that temperatures in Ontario had been cool in July 2009 and he wondered why nobody had bothered to issue a global cooling alert; if the temperatures had been unusually warm, wouldn’t that have been blamed on global warming? Murphy wrote:

What we do not hear from them [the global warming believers], from any one of them, is the slightest indication of puzzlement over how or why so suddenly, in this age of the greatest emergency our planet has ever faced—global warming—things have gotten cool. Not a furrowed brow among the lot over the consideration that, contrary to the visions of Al Gore and David Suzuki or NASA’s own anti-global warming Nostradamus, James Hansen, the great trend line of an ever-warming world is being contradicted nightly in their own forecasts.

To show how wrong Murphy had been, Pederson presented a PowerPoint slide showing that, contrary to Murphy’s column, July 2009 was quite hot in most of the planet, and suggested—to audience laughter—that Murphy was foolishly guilty of assuming the weather in Toronto represented the world. Below is the map Pederson used, from the National Oceanic and Atmospheric Administration (NOAA) website.



Pederson also accused Murphy not just of being foolish, but of being unethical as well in spreading climate skeptic lies.

Murphy is anything but foolish—a Rhodes scholar, he’s probably got the finest mind in Canadian journalism. Nor is he wrong or naive about the planetary cooling trend. For example, Murphy is quite aware of the difference between weather and climate, writing in his column: "Not that these studio meteorologists were making the elementary mistake of confounding weather with climate, for this is a distinction familiar now even to kindergartners." [Much less, one might add, to Rhodes scholars.]

And he is quite aware that Ontario’s weather doesn’t represent the globe’s weather. He was making a broader point about the trend toward global cooling in the past decade—a point that Pederson, deliberately or unconsciously, sidestepped.

The U.S. is cooling, not warming

Let’s take a closer look at the average U.S. temperature in July, 2009, also from the NOAA website:


NOAA temperatures July 2009

All that blue indicates that, yes, July was, as Murphy said, colder than normal in the northern and eastern parts of the United States, in some cases record cold. Granted, the planet won’t be uniformly warm (or cold), but record cold? In July? At a time when the planet is supposed to be not only warming, but experiencing (according to IPCC president Rajendra Pachauri) “accelerated” warming? (See Christopher Monckton’s article debunking this claim.)

Also on the NOAA website is a handy gadget that lets users calculate for themselves temperatures and trends over the past 115 years in the continental United States (my thanks to C3 Headlines for bringing this website to my attention). You just put in the date you want to begin, any time from 1895 on, the date you want to end, and a month or the annual average. The U.S. has the world’s best climate records, so the temperatures in the U.S. will mirror, reasonably well, temperatures in the Northern Hemisphere and almost certainly the planet as well.

Here’s what the graph shows if you input the years 1997-2010:


NOAA temperatures 1997-2010

Good heavens! Since 1997 the planet (or at least the U.S. portion of it) has been cooling! Just like Murphy said in his column. And this cooling is not just a 2009 phenomenon.

If you input 1996-2010, the temperature is flat-lined, so the cooling started at least in 1997 in the U.S., and almost certainly everywhere else as well. And, the later you put the end date, the more pronounced is the downward, cooling slant of the temperature line.

Phil Jones: the planet isn’t warming

Murphy’s view fits very well with what Phil Jones, the former head of East Anglia University’s Climatic Research Unit, said in one of his “Climategate” emails (July 5, 2005): "The scientific community would come down on me in no uncertain terms if I said the world had cooled from 1998. OK it has but it is only seven years of data and it isn’t statistically significant."

In other words, in 2009 Murphy was writing about a global cooling (not warming) trend that even climate alarmist Phil Jones admitted began in 1998.

Jones further admitted in a Feb. 13, 2010, interview with the BBC that there had been no “statistically significant” warming since 1995, and evidence of cooling (although not “statistically significant” for Jones) since 2002. Here’s what Jones said about the cooling: "BBC: Do you agree that from January 2002 to the present there has been statistically significant global cooling? Jones: No. This period is even shorter than 1995-2009. The trend this time is negative (-0.12C per decade), but this trend is not statistically significant."

But if the temperature “trend” might be toward cooling, that at least means that there was no statistically significant global warming during the years from 2002-2010, does it not? And the planet may well be cooling—NOAA’s U.S. data certainly points that way. Jones argues the timeline isn’t long enough to establish a cooling trend, but 12 years of no warming certainly looks like a trend. It’s also 12 years, or more, during which the public has been relentlessly—and, it appears, falsely—bombarded with the message that the planet is suffering from out-of-control warming.

So let’s summarize: Pederson accused Murphy of being an unethical columnist for claiming that the planet was cooling in 2009. Yet NOAA, which is a strong believer in anthropogenic global warming, says the United States has been cooling since 1997. Phil Jones suggests in his email that the planet—not just the U.S.—has not warmed since 1995 (with the addition that he doesn’t want this news to get out, hence “hide the decline”), and might even have cooled since 2002. So, who’s right? Pederson? Or Murphy, along with both NOAA and Jones?

At the very least, how can Pederson, with a straight face, accuse Murphy of lack of ethics, thereby slandering Murphy’s journalistic reputation, when Murphy is simply basing his opinion on scientific data? In other words, at least in my opinion, Pederson slandered Murphy and owes him an apology.

Ignoring the evidence

But, then, this is what AGW believers do. Evidence that the planet hasn’t warmed since the late 1990s is dismissed as “cherry-picking” because, for warmists, the overall trend is up. It has to be up, because that’s what the computer climate models say, and the models cannot be wrong.

Pederson set up the climate and media panel so there were no skeptics on board because he is a dedicated, one might even say fanatical, believer in human-caused global warming and its catastrophic outcome. How do I know? Because last December, I attended a video streaming, arranged by Pederson in a University of Victoria classroom, of an online debate pitting skeptics Bjorn Lomborg and Nigel Lawson against warmists Elizabeth May and George Monbiot.

Before the debate began, however, Pederson went to the front of the classroom and, for 15 minutes, told those attending that they shouldn’t believe a word of what Lomborg and Lawson said. The idea that a university audience might listen to a debate with an open mind is apparently beyond Pederson’s ability to comprehend because, of course, he believes he is totally right on global warming and any other viewpoint is totally wrong.

(As an aside, philosopher of science Karl Popper has written, in The Logic of Scientific Discovery (p. 281): “The wrong view of science reveals itself as the craving to be right.” Pederson, and global warming alarmists in general, seem to be strongly in the grip of this craving.)

Why warmists can’t admit cooling

During question period at the media and climate panel, I asked Pederson about Jones’s comment on the lack of “statistically significant” warming since 1995 and the possible cooling from 2002 on. Pederson replied that the 1995 non-warming was just that, a statistical artifact, and that the current decade had been the warmest on record. Which may be true, but that doesn’t mean the decade is warming.

However, Pederson refused to answer the second part of my question on Jones’s comment about possible cooling.

Pederson’s refusal to respond made it very clear that warmists don’t want to publicly acknowledge any cooling over the past 12 or 13 years (from 1997 in the U.S. and probably everywhere else, too). And so, they pour scorn on anyone, like Murphy or myself, who dares to mention it.

By why is it so important not to admit that the planet has cooled, at least to the public? I must confess that this question has puzzled me, or did until the media and climate panel.

One reason is, of course, because scientists like Pederson know the public will lose faith in the AGW theory if what it predicts—warming—isn’t occurring. How silly of the public to demand actual evidence of warming before making some very expensive decisions to cope with warming, but there it is.

The main reason, though, is that to acknowledge cooling over the past decade is to admit that the AGW hypothesis is wrong. Why? Jones provides a clue when he says that while the planet isn’t warming and is actually cooling, it hasn’t warmed or cooled for enough years to be “statistically significant.”

So, how many years does it take for a climatologist to accept that climate change, as opposed to weather fluctuation, has occurred (is “statistically significant”)? The generally accepted time is 30 years. How long has the planet been warming? From the mid-1970s to no later than 1998. That’s 23 years of warming, followed by 12 years of non-warming (so far). In other words, this warming that we’re told is so “unequivocal” and “settled” and “certain” has not passed the crucial 30-year mark. The warming of 1975-1998 is therefore not “statistically significant.”

Hence, it is necessary for climatologists like Pederson to assert, at least to the public, that warming has occurred after 1998 and, more recently, that it is actually “accelerating.” Without warming in the 21st century, “global warming” hasn’t reached the crucial 30-year milestone. But if for Pederson there is no statistically significant cooling over the past decade, there was also no statistically significant warming in the late 20th century, either. Warmists like Pederson cannot admit this fact because it utterly destroys their case.

In other words, it’s not Rex Murphy who is misleading the public with ideology and false information. It’s the alarmist climatologists like Pederson who are misleading the public with their smokescreen of “certainty” and “consensus” and “global warming” that not only hasn’t occurred in more than a decade, but wasn’t “statistically significant” before that.
