The Science is NOT settled

Wednesday, February 17th, 2010

Professor Phil Jones was  head of the Climate Research Unit (CRU) at the University of east Anglia before Climategate.  He was in charge when all the numbers were put together that were used by IPCC  but he stood down pending an investigation.   CRU is one of the three sources of data for IPCC so comments by Jones are critical to the credibility of the IPCC.  In an interview on the BBC recently, Professor Jones said that there has been no “statistically significant” global warming since 1995.  To be specific, the “trend (0.12C per decade) is positive, but not significant at the 95% significance level.”  In the same interview, he also conceded that the Middle Ages may have been warmer than now and went further by admitting that the science of climate change is far from settled  “There is still much that needs to be understood to reduce uncertainties”.

If the world knew all this in 1995, there would never have been a Kyoto accord, Al Gore would not have produced his slanted “Inconvenient Truth”, there would not have been a Copenhagen summit, there would not have been any proposals to implement Carbon trading – in short, we could have devoted all that energy to more useful things.

But the political momentum is hard to slow down – it takes politicians a long time to learn and an equally long time to unlearn.

IPCC Scientist calls for Pachauri to resign

Thursday, January 28th, 2010

A senior Canadian climate scientist says the United Nations’ panel on global warming has become tainted by political advocacy, that its chairman should resign, and that its approach to science should be overhauled.  Andrew Weaver, a climatologist at the University of Victoria, was interviewed by Canwest News Service and said that the leadership of the Intergovernmental Panel on Climate Change (IPCC) has allowed it to advocate for action on global warming, rather than serve simply as a neutral science advisory body.

“There’s been some dangerous crossing of that line,”  he said on January 26, 2010.  “Some might argue we need a change in some of the upper leadership of the IPCC, who are perceived as becoming advocates,” he told Canwest News Service. “I think that is a very legitimate question.”

Dr. Weaver also says the IPCC has become too large and unwieldy. He says its periodic reports, such as the 3,000 page, 2007 report that won the Nobel Prize, are eating up valuable academic resources and driving scientists to produce work on tight, artificial deadlines, at the expense of other, longer-term inquiries that are equally important to understanding climate change. “The problem we have is that the IPCC process has taken on a life of its own,” says Dr. Weaver, a climate-modelling physicist who co-authored chapters in the past three IPCC reports.  “I think the IPCC needs a fundamental shift.”

Dr. Weaver says Dr. Pachauri, the panel’s chairman, should resign, not only for his recent failings but because he was a poor choice to lead the IPCC to begin with.

He still believes in Global warming and being an “insider”, his comments are significant.  Terence Corcoran of the National Post comments on this report with:

That Mr. Weaver now thinks it necessary to set himself up as the voice of scientific reason, and as a moderate guardian of appropriate and measured commentary on the state of the world’s climate, is firm evidence that the IPCC is in deep trouble. He’s getting out while the getting’s good, and blaming the IPCC’s upper echelon for the looming crisis.

In the language typical of an IPCC report, one might say that the radiative forcing created by Climategate and Glaciergate strongly suggest this is very likely to bring about cataclysmic melting of the organization within the next portion of the current decadal period. The words “very likely” in IPCC risk assessment terms mean a 90% or greater probability that something will happen. As it looks now, the IPCC is burnt toast and unless it is overhauled fast there’s a 90% probability the climate-change political machine is going to come crashing down.

IPCC quote on glacier melting was false

Wednesday, January 20th, 2010

In the IPCC report of 2007, it was said that the glaciers in the Himalayas would be all melted by 2035.  Yet it has now been revealed that this was never true.  The Indian Government is now saying that there is no sign of any abnormal retreat and that the IPCC is alarmist.  The path of the story is long and convoluted but the IPCC never checked its accuracy, it was never peer reviewed and the original author even said it was speculation.  Further, the scientist who uncovered the error is Canadian Professor Graham Cogley of Trent University who is an IPCC author and not what would be called a skeptic.  Another IPCC scientist had pointed out this error in 2006.  Austrian Glaciologist Georg Kaiser notified his IPCC colleagues of the “huge” Himalayan mistake: “This number is not just a little bit wrong, it is as wrong as can be wrong….  It’s so wrong that it is not even worth discussing”.  But of course his comments were ignored.

The IPCC is of course denying that the mistake is significant – what else would they say?

Here we have another example of falsified data.  It’s supposed to be “scientific” and “peer reviewed”.  The science is supposed to be “settled”.  Sounds like politics and not science to me.

Temperature data does not support climate scare

Sunday, December 13th, 2009

Every now and then, we need a touch of reality.  There are quite accurate measurements of actual global temperature available – they are taken from satellites and measure the natural microwave thermal emissions from oxygen in the atmosphere. The signals that these microwave radiometers measure at different microwave frequencies are directly proportional to the temperature of different, deep layers of the atmosphere.   Roy Spencer, climatologist  and former NASA scientist collects this data regularly and produces this graph.

Global temperature - 1979 - Nov 2009

Global temperature - 1979 - Nov 2009

What does this mean?  It does not mean we currently have global warming as predicted by IPCC.  If you follow the redline, you can see that its centre line is at 0.2 deg  for the period 2001 to 2009.  This is a lot less than what has been claimed.  If this trend continued, in another 30 years (2039) there would be 0.4 deg  and it would take 300 years to reach 2.0 degrees.

And still, the only reason given for the idea that even this small amount is caused by man is a computer model that scientists say they don’t fully understand (ask them about feedback) yet they use it to project warming.  They can’t even make a model to accurately predict short term weather – why would we believe they can predict it long term?  Why are we all bamboozled by scientists twisting models and data to prove something they have decided in advance?

No warming in last 10 years now confirmed by climatologists.

Friday, November 20th, 2009

The prestigious German magazine, Der Speigel, has published an article confirming that climate scientists are now certain that the world’s climate has not warmed at all between 1999 to 2008.  This despite the fact that the IPCC assumed it rose 0.2C in this time frame.

These same scientists say that the climate warmed by 0.7C from the late 1970’s to the late 1990’s but “At present, however, the warming is taking a break,” confirms meteorologist Mojib Latif of the Leibniz Institute of Marine Sciences in the northern German city of Kiel. Latif, one of Germany’s best-known climatologists, says that the temperature curve has reached a plateau. “There can be no argument about that,” he says. “We have to face that fact.”

This raises doubts about the predictive value of climate models and Jochem Marotzke, director of the Max Planck Institute for Meteorology in Hamburg says “We don’t really know why this stagnation is taking place at this point.”

According to Der Speigel, just a few weeks ago, Britain’s Hadley Centre for Climate Prediction and Research added more fuel to the fire with its latest calculations of global average temperatures. According to the Hadley figures, the world grew warmer by 0.07 degrees Celsius from 1999 to 2008 and not by the 0.2 degrees Celsius assumed by the United Nations Intergovernmental Panel on Climate Change. And, say the British experts, when their figure is adjusted for two naturally occurring climate phenomena, El Niño and La Niña, the resulting temperature trend is reduced to 0.0 degrees Celsius — in other words, a standstill.

The differences among individual regions of the world are considerable. In the Arctic, for example, temperatures rose by almost three degrees Celsius, which led to a dramatic melting of sea ice. At the same time, temperatures declined in large areas of North America, the western Pacific and the Arabian Peninsula. Europe, including Germany, remains slightly in positive warming territory.

Some scientists are trying to explain away the plateau but are concerned about their loss of credibility – surprise!

Reducing CO2 is good – but not because of Climate Change.

Thursday, October 1st, 2009

The Cap and Trade bill that the U.S. is trying to get passed focuses on CO2 reduction – the intent is a vain attempt to reduce global warming due to a small greenhouse effect.  Other countries such as Canada will follow suit with similar programs if the U.S. bill passes.  Carbon Dioxide mostly results from burning of one form and another although small amount comes from the breathing of animals (like humans).  Burning comes partly from things like forest fires and burning garbage but a large contribution comes from burning coal, oil and natural gas as a fuel for transportation and electricity generation.

Conservation of Fossil fuels is a good idea although the need is not nearly as urgent as the global warming alarmists would have us believe.  There is only a limited amount of coal, oil etc in the ground so it must eventually run out.  Cap and Trade and similar programs will mostly affect the burning of fossil fuels and anything that reduces our consumption of them is necessarily good.

So in a backwards kind of way, CO2 reduction programs are good although premature – we don’t need it yet.  I would compare the whole thing to the drive several hundred years ago to get a shorter route to China by crossing the Atlantic – a good idea for the wrong reason.

It’s not like the only value of coal, oil or natural gas is as a fuel.  They are the best and cheapest source of hydro-carbons for synthetic materials – commonly called plastics.

Although I am skeptical about the weak science of global warming, some of the actions proposed should be done. It’s a pity the only way politicians can be motivated to reduce consumption of fossil fuels is through scare tactics about Climate change.  Maybe the IPCC scientists knew that?  Maybe they said – “well if we are wrong, it’s good to reduce CO2 anyway”.  Methane is a many times worse greenhouse gas yet there’s little talk about that.  (It comes from cattle and marshes so is quite common.)

Top Climate Scientists agree Models are not yet accurate

Friday, September 11th, 2009

One of the prestigious magazines in the scientific world is New Scientist.  They have long supported the establishment cause of Global Warming and only quote scientists who would be accepted by others in their field.  And in an article published Sept 4, New Scientist said: “Forecasts of climate change are about to go seriously out of kilter. One of the world’s top climate modellers said Thursday we could be about to enter one or even two decades during which temperatures cool.”  “People will say this is global warming disappearing,” he told more than 1500 of the world’s top climate scientists gathering in Geneva at the UN’s World Climate Conference.  “I am not one of the sceptics,” insisted Mojib Latif of the Leibniz Institute of Marine Sciences at Kiel University, Germany. “However, we have to ask the nasty questions ourselves or other people will do it.”

It should be noted that Latif is the lead author on the IPCC and not easily dismissed.

According to New Scientist,

This is bad timing. The UN’s World Meteorological Organization called the conference in order to draft a global plan for providing “climate services” to the world: that is, to deliver climate predictions useful to everyone from farmers worried about the next rainy season to doctors trying to predict malaria epidemics and builders of dams, roads and other infrastructure who need to assess the risk of floods and droughts 30 years hence.

But some of the climate scientists gathered in Geneva to discuss how this might be done admitted that, on such timescales, natural variability is at least as important as the long-term climate changes from global warming. “In many ways we know more about what will happen in the 2050s than next year,” said Vicky Pope from the UK Met Office.

Latif predicted that in the next few years a natural cooling trend would dominate over warming caused by humans. The cooling would be down to cyclical changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO).

Breaking with climate-change orthodoxy, he said NAO cycles were probably responsible for some of the strong global warming seen in the past three decades. “But how much? The jury is still out,” he told the conference. The NAO is now moving into a colder phase.

Latif said NAO cycles also explained the recent recovery of the Sahel region of Africa from the droughts of the 1970s and 1980s. James Murphy, head of climate prediction at the Met Office, agreed and linked the NAO to Indian monsoons, Atlantic hurricanes and sea ice in the Arctic. “The oceans are key to decadal natural variability,” he said.

Another favourite climate nostrum was upturned when Pope warned that the dramatic Arctic ice loss in recent summers was partly a product of natural cycles rather than global warming. Preliminary reports suggest there has been much less melting this year than in 2007 or 2008.

And further, they admitted that you can’t trust models. What?  They agree with what sceptics have been saying?

In candid mood, climate scientists avoided blaming nature for their faltering predictions, however. “Model biases are also still a serious problem. We have a long way to go to get them right. They are hurting our forecasts,” said Tim Stockdale of the European Centre for Medium-Range Weather Forecasts in Reading, UK.

The world may badly want reliable forecasts of future climate. But such predictions are proving as elusive as the perfect weather forecast.

Next they’ll be saying that any warming is not caused by man’s actions at all.  Certainly they are saying that man’s impact is very small compared to the impact of mother nature.  Otherwise man’s impact would over-ride nature’s effects.  They are also saying that long term climate predictions are about as hard as long term weather forecasts.

Why Global Warming alarmists are losing their case

Saturday, August 29th, 2009

Norman Rogers has written an excellent summary of the current situation with the arguments about climate change.  You can have a look here or read my summary below.  I rarely read the whole text of a long article on the internet so my summary/précis will help anyone else who just wants the meat.  Besides, it needs to be distributed as much as possible.

Global Warming Blues – summary of an article by Norman Rogers Aug 27, 2009
Most scientists don’t have a good grasp of the big picture because they are narrowly specialized and don’t think about much outside of their immediate interests. The scientists that do have a grasp of the big picture can be divided into global warming advocates, skeptics and the majority of passive observers who play it safe by not taking a position. The global warming advocates have the upper hand and the most power. The skeptics, including quite a few excellent scientists, are marginalized and frankly persecuted. They are whistle blowers.

Global warming scare stories are good for global warming science because the scare stories promote research funding.  If it weren’t for the scary predictions these scientists would be toiling in a poorly funded and obscure branch of academic science.  As the distinguished climate scientist Richard Lindzen noted in an article, fear is more effective than gratitude for inducing financial support.

The Intergovernmental Panel on Climate Change or IPCC is a branch of the United Nations and is very much under the control of  climate doomsters. If climate doom were not impending the IPCC would not be necessary, thus it is a bureaucratic imperative that the IPCC predicts climate doom. The IPCC and Al Gore were jointly given the 2007 Nobel Peace Prize. The peace prize is given by politicians for political reasons and the 2007 recipients have shown themselves to be accomplished politicians. The history of the Nobel Peace Prize does not inspire confidence. Some of the recipients have been crackpots (Linus Pauling ) and others fraudsters (Rigoberta Menchu). Gore seems to me to be a combination of both.

The increase in temperature predicted by the global warming computer models is about 3 degrees Celsius. This isn’t very scary, so the promoters of global warming  alarmism come up with additional scare stories. For example, there will be more hurricanes, the ice caps will melt, the polar bears will die, the oceans will become acid and kill the coral, and weather will become more extreme. These stories have much less scientific support than the warming theories, and each has been rebutted. Scare stories attract attention and it is much more difficult to refute scare stories than it is to create them. By the time one scare story becomes discredited a new scare story is spread.

Organized science has relinquished its traditional role as an objective advisor to policy makers and has instead become a lobbyist for its own interests. The interests of big science happen to coincide with the ideological goals of the green movement. The resulting coalition has impressive political power.
The science behind the IPCC predictions and the scary claims is incredibly weak, really bordering on fantasy.  Certainly great progress has been made in understanding how the climate works in the last 40 years. But that understanding has not reached the point where we can have any faith in future predictions of the effects of greenhouse gases in the atmosphere. Since vast efforts and billions of dollars have been invested in huge computer climate models the scientific organizations are forced to defend the usefulness of the models. The way in which the IPCC has utilized climate models to make predictions is really quite comical, although it takes a lot of study and wading through a molasses-like report to get to the point where it starts to seem funny. I have a 40 page article on my website if you would like to know the details.

Kevin Trenberth, no global warming skeptic, is one of the most prominent climate scientists in the world. He is a senior scientist and the Head of the Climate Analysis Section at the National Center for Atmospheric Research (NCAR). He said this  about climate models.

… None of the models used by IPCC are initialized to the observed state and none of the climate states in the models correspond even remotely to the current observed climate. In particular, the state of the oceans, sea ice, and soil moisture has no relationship to the observed state at any recent time in any of the IPCC models. …

He is confessing that climate models leave a lot to be desired.

Clouds are very important, but it is generally accepted that the treatment of clouds by the computer models is very poor.

The 20 or so climate models used by the IPCC don’t agree with each other as to how much warming would take place due to doubling CO2. The range is 2 to 4-1/2 degrees Celsius. There are perfectly plausible theories, based on observations, not models, that the warming would be far less, from scientists such as Richard Lindzen, Stephen Schwartz and Roy Spencer.

A 3 C degree increase in global temperature is the difference between Chicago and St. Louis.

The climate of the 20th century is inconsistent with the climate models and in fact can’t be explained within the IPCC framework. The climate of the 20th century is characterized by warming from 1910 to 1940 followed by cooling between 1940 and 1970 and then more warming from 1970 with an apparent cessation of the warming during the last decade.  This is illustrated by the graph below.

Climate in the 20th Century

Climate in the 20th Century

The attempts to make the 20th century climate consistent with the computer models simply don’t work.

Controlling our own carbon dioxide emissions accomplishes practically nothing if the Chinese and Indians don’t control theirs. They play along as long as it seems profitable. The Chinese and Indians are like the natives who happily attend church services as long as the missionaries are giving out free dinners.

Green electric power from windmills and solar energy is impracticable.  It’s expensive and due to the erratic nature of sunshine and wind, solar and wind power must be backed up by duplicate power plants or by energy storage systems that are as expensive as duplicate power plants. It sometimes seems that the advocates of solar power don’t realize that the sun does not shine at night. The much acclaimed Kyoto Treaty for the reduction of CO2 illogically does not give CO2 reduction credit for CO2-free nuclear power plants, something put in the treaty in response to green lobbying.

The global warming skeptics should to be given some respect and a chance to make their case.

Focus on adapting to Climate and not trying to control it

Wednesday, August 26th, 2009

The latest reports from NASA are that “the planet’s ocean surface temperature was the warmest on record for July,” They also reported  that, “Large portions of many continents had substantially warmer-than-average temperatures during July 2009.” But it also mentions that, “Cooler-than-average conditions prevailed across southern South America, central Canada, the eastern United States, and parts of western and eastern Asia.

So now people who believe the scare stories will be saying that they were right after all.  Is it now skeptics turn to say “But one month does not make a trend”?  It is true that one month, one year or even one decade do not make a trend.  In fact 20 years does not make a trend since natural cycles are measured in many decades or even centuries.  But the really big issue is not really whether the climate is changing – it clearly always has – both warmer and colder.  The issue is whether it is man-caused (Anthropogenic Global Warming – AGW)

I keep coming  back to the statement by the IPCC (I paraphrase here): “The only reason we can think of that would cause the observed warming is the greenhouse effect”.  (For more on this, see the link in a comment to the previous article )  Well maybe there are things about climate that we don’t know enough about – especially what the sun does and its cycles.

When you look at the issue from the 30,000 foot level, it’s clear that irrespective of whether there is an AGW component or not, man has so far not done anything to reduce the impact and is not likely to be able to affect climate in the future.  This will be because either it’s not AGW or because the politics are against action or both. We should therefore focus our efforts on adapting to whatever the climate happens to be and not trying to control it.

The world has done nothing about C02 in 20 years

Thursday, August 20th, 2009

An article about a radical way to cool the earth by 1 to 2 % contains some interesting data.  It’s doubly interesting because the data was supplied by advocates of ways to combat AGW.

In a paper released earlier this month, two climate change gurus say that we – meaning the world – have actually done nothing to reduce CO2 emissions since the alarm was raised 20 years ago.

J. Eric Bickel and  Lee Lane wrote a paper titled “An Analysis of Climate Engineering as a Response to Climate Change“,  where they suggest using ships to spray salt into the atmosphere.  If volcanoes can cool the world, so can a salt spray! (As an aside, the qualifications of these folks who are lauded as climate experts are no different than the qualifications of people like Ian Plimer who are criticized as not being real climate experts).

“The historical record is clear,” they say. They note that 2008 marked the 20th anniversary of the first meeting of the IPCC, whose mission was to devise the solution to global warming. Yet in 2008, the U.S. Energy Information Administration reported that global emissions of carbon dioxide were more than one-third higher than they were in 1988 – and that the rate of increase had accelerated. In fact, Prof. Bickel and Mr. Lane say, emissions grew four times more quickly between 2000 and 2007 than they did between 1990 and 1999.

“Thus, 20 years of protracted diplomatic talk and laborious scientific study,” they say, “have so far failed to move the needle on emission rates.” As for the countries that signed the Kyoto Protocol, “most signatories are failing to reduce emissions, much less meet their targets.” The trend lines remain clear. Essentially, the authors suggest, there is no reason to think that anything will be done, notwithstanding the increase in rhetoric.

Ships that spray salt into the atmosphere to cool the earth down.

Ships that spray salt into the atmosphere to cool the earth down.

They suggest that the cost of their approach would be  a fraction of the cost of reducing carbon emissions which they say is not going to happen anyway.

But to me, the really interesting thing is that they actually come out and say that CO2 in the atmosphere is continuing to rise and no-one in the world has so far done anything about it.  Further, they say that this is not likely to change in the future.

It’s fascinating that they think that “the world” will not do anything about CO2 emissions yet they offer a solution which is even less likely to be implemented.

If the world is truly warming, and if the people of the world either are not causing it OR won’t change behavior to stop the warming, then we had better come up with a plan.  How about finding ways to cope?  The world found ways to cope in past ice ages – the difference now is massively more people and established infrastructure.  But it may need to be done.  But then, maybe we should plan for another ice-age – it’s just as likely.
