MIT Climate Scientist Dr. Richard Lindzen told Climate Depot on September 27, 2013:
I think that the latest IPCC report has truly sunk to level of hilarious incoherence. They are proclaiming increased confidence in their models as the discrepancies between their models and observations increase.
Their excuse for the absence of warming over the past 17 years is that the heat is hiding in the deep ocean. However, this is simply an admission that the models fail to simulate the exchanges of heat between the surface layers and the deeper oceans. However, it is this heat transport that plays a major role in natural internal variability of climate, and the IPCC assertions that observed warming can be attributed to man depend crucially on their assertion that these models accurately simulate natural internal variability. Thus, they now, somewhat obscurely, admit that their crucial assumption was totally unjustified.
Finally, in attributing warming to man, they fail to point out that the warming has been small, and totally consistent with there being nothing to be alarmed about. It is quite amazing to see the contortions the IPCC has to go through in order to keep the international climate agenda going.
A 2007 prediction that summer in the North Pole could be “ice-free by 2013” that was cited by former Vice President Al Gore in his Nobel Peace Prize acceptance speech has proven to be off… by 920,000 square miles.
In his Dec. 10, 2007 “Earth has a fever” speech, Gore referred to a prediction by U.S. climate scientist Wieslaw Maslowski that the Arctic’s summer ice could “completely disappear” by 2013 due to global warming caused by carbon emissions.
However, instead of completely melting away, the polar icecap is at now at its highest level for this time of year since 2006.

Global warming is just HALF what we said: World's top climate scientists admit computers got the effects of greenhouse gases wrong
By DAVID ROSE
A leaked copy of the world’s most authoritative climate study reveals scientific forecasts of imminent doom were drastically wrong.
The Mail on Sunday has obtained the final draft of a report to be published later this month by the UN Intergovernmental Panel on Climate Change (IPCC), the ultimate watchdog whose massive, six-yearly ‘assessments’ are accepted by environmentalists, politicians and experts as the gospel of climate science.
They are cited worldwide to justify swingeing fossil fuel taxes and subsidies for ‘renewable’ energy.
Yet the leaked report makes the extraordinary concession that the world has been warming at only just over half the rate claimed by the IPCC in its last assessment, published in 2007.
Back then, it said that the planet was warming at a rate of 0.2C every decade – a figure it claimed was in line with the forecasts made by computer climate models.
But the new report says the true figure since 1951 has been only 0.12C per decade – a rate far below even the lowest computer prediction.
The 31-page ‘summary for policymakers’ is based on a more technical 2,000-page analysis which will be issued at the same time. It also surprisingly reveals: IPCC scientists accept their forecast computers may have exaggerated the effect of increased carbon emissions on world temperatures – and not taken enough notice of natural variability.
lThey recognise the global warming ‘pause’ first reported by The Mail on Sunday last year is real – and concede that their computer models did not predict it. But they cannot explain why world average temperatures have not shown any statistically significant increase since 1997.
lThey admit large parts of the world were as warm as they are now for decades at a time between 950 and 1250 AD – centuries before the Industrial Revolution, and when the population and CO2 levels were both much lower.
lThe IPCC admits that while computer models forecast a decline in Antarctic sea ice, it has actually grown to a new record high. Again, the IPCC cannot say why.
Al Gore and his traveling medicine show is back in town with his new, improved snake oil, guaranteed to grow hair, improve digestion, promote regularity and kill roaches, rats and bedbugs. Al and his wagon rumbled into town on the eve of “a major forthcoming report” from the Intergovernmental Panel on Climate Change, which is a panel of scientists affiliated with the United Nations. Their report is expected to buck up the spirits of the tycoons of the snake-oil industry.
A snake-oil salesman’s lot, like a policeman’s, is not a happy one. There’s always a skeptic or two (or three) standing at the back of the wagon, eager to scoff and jeer. The global-warming scam would have been right up Gilbert and Sullivan’s street. Would Al and the U.N. deceive us? No! Never! What! Never? Weeeell, hardly ever.
The New York Times, a faithful shill for Al’s snake-oil elixir, following the wagon from town to town, got an advance copy of the U.N. report and gives out with the “good” news: It’s a “near certainty” that humans are responsible for the rising temperatures of recent decades, and warns that by the end of the century all the little people — small children, midgets and others whose growth was stunted by drinking coffee and smoking cigarettes at an early age — will be up to their belly buttons in salt water. The seas will rise by more than three feet.
The inconvenient truth Al and the junk scientists have to deal with is that temperatures aren’t rising, but falling. In fact, since the early 1990s we’ve had global cooling. It got so embarrassing Al and the junk scientists started calling it “climate change.” Some days it rains, some days it doesn’t and some days it’s a little of both. That’s real change. The U.N. panel concedes that global warming has in fact given way to global cooling, but attributes this to “short-term factors.” The minions of the compliant media, ever eager to blow hard about the coming end of the world, when women and minorities will suffer most, will rattle and twitter about the U.N. climate report with their usual tingle and flutter.
President Obama tried the other day to elbow Al aside to lead with his assertion that hurricanes are getting worse and that only he has the power to put them in their place. Hurricanes are actually getting not worse, but fewer. Only three major hurricanes have made landfall so far in Mr. Obama’s presidency. Grover Cleveland, who was president between 1885 and 1889, entertained 26 major hurricanes during his presidency, and that was before global warning was invented.
We were scheduled to see an enormous melting of polar ice by now, but even the ice won’t co-operate. The U.S. Navy forecasts twice as much mid-September ice this year as it measured in 2012.
The only way to deal with the inconvenient truth is to bellow and bawl the convenient whopper louder than ever. In an interview this week with a blogger for The Washington Post, Ezra Klein greeted Al with a shower of sanitized softballs, and Al knocked some of them halfway back to the pitcher’s mound. Al is exhausted dealing with the skeptics, whom he calls “denialists,” as in denying the Holocaust. The denialists, he says, are “like a family with an alcoholic father who flies into a rage every time a subject is mentioned and so everybody avoids the elephant in the room to keep the peace.”
Al, who is a decent sort who tried to be a good ol’ boy when he went back home to visit the family tobacco farm, says the denialists remind him of racists, warmongers, homophobes and other congenital undesirables, but he thinks it won’t be long until they’re permanently silenced. “We’re winning the conversation,” he says.
On the contrary, what frustrates Al and the snake-oil industry is that the skeptics can no longer be shut out of the conversation. “We can expect the climate crisis industry to grow increasingly shrill, and increasingly hostile toward anyone who questions their authority,” Kenneth P. Green, a former member of the U.N. panel, predicted three years ago. Another former panelist, Dr. Kimimori Itoh, a Japanese physical chemist, calls the phenomenon “the worst scientific scandal in history. When people come to know what the truth is, they will feel deceived by science and scientists.”
That’s too bad, because when science and scientists one day discover a genuine crisis, nobody will listen. We’re up to our ears already in snake oil.

HOCKEY STICK REDUX
POSTED ON MARCH 13, 2013 BY JOHN HINDERAKER IN CLIMATE
"Last week, a group of climate alarmists headed by Shaun Marcott, a geologist at Oregon State, released a study that purported to resurrect the infamous hockey stick. Relying on an assortment of data sources, Marcott and his colleagues tried to reconstruct global temperatures over the last 11,000 years, since the end of the last Ice Age. While acknowledging that the Earth has often been warmer than it is today, they claimed that the Earth is now the warmest it has been “in at least 4,000 years,” and that the rate of warming over the last 100 years is unprecedented. Voila! The hockey stick returns. Naturally, the study was acclaimed uncritically in the press; this NPR story titled “Past Century’s Global Temperature Change Is Fastest On Record” offers a good summary of Marcott’s research.
There are two fundamental problems with Marcott’s claims. First, thermometers have been in existence for only a very small portion of the last 11,000 years. It is hard enough–some say impossible–to calculate even the current average temperature of the Earth. To compare 100 years of contemporary records against reconstructions of thousands of years based on proxies like tree rings and ice cores is, at best, matching an apple against millenia of oranges. Second, the Marcott reconstruction is contradicted by just about everything we know about the temperature history of the last 11,000 years.
Anthony Watts is in the midst of a three-part analysis of Marcott’s study. Part 2 addresses the inconsistency between Marcott’s reconstruction and the climate record as revealed by our most reliable data sources. Here are some excerpts:
Both the Greenland GISP2 temperature curve (Figure 1B) and the oxygen isotope curve (Figure 1C) clearly show that except for the Little Ice Age and Dark Ages Cool Period, temperatures for all of the past 4,000 years have been warmer than the end of the ice core (1950 AD). The Medieval Warm Period was 1.1° C warmer than the top of the core (1950) and at least four other warm periods of equal magnitude occurred in the past 4,000 years; four other warm periods were ~1.3°C warmer; two other warm period were 1.8-2.0°C warmer; and one warm period was 2.8°C warmer. At least a dozen periods more than 1°C warmer than 1950 occurred, clearly contradicting the Marcott et al. conclusions.
The top of the GISP2 ice core is 1950 AD, so we need to look at more recent temperatures in Greenland in order to get to the “present temperature,” i.e., has the temperature in Greenland risen since 1950? Figure 2 shows 1880 to 2004 temperatures in Greenland (Chylek et al., 2004, 2006). Temperatures in 2004 were slightly lower than in 1950, so temperatures at the top of the Greenland ice core are not significantly different than those “at present.”
Next, Watts addresses Marcott’s assertion that “Global temperature…has risen from near the coldest to the warmest levels of the Holocene within the past century. A heat spike like this has never happened before, at least not in the last 11,300 years.”
Let us test this conclusion against real-time data. First, their statement that “Global temperature…has risen from near the coldest to the warmest levels of the Holocene within the past century” is not true. The coldest part of the Little Ice Age occurred about 400 years ago, during the Maunder Minimum, so right off the bat, their conclusion is flawed. They appear to be unaware of the cyclic nature of temperature change and use the low point of the 1880-1915 cool period as their starting point for assessing the rate of warming over the “past century,” rather than 1913-2013. Comparing the depth of cooling in a cool period with a warm period peak is comparing apples and oranges. It distorts the real rate, which should be measured from cool peak to cool peak or warm peak to warm peak. The 1880-1915 cool period was followed by the 1915-1945 warm period, the 1945-1977 cool period, and the 1978-1998 warm period (Figure 4). The rate of warming from 1913 to 2013 is about 0.7°C per century (which is about the same as the warming rate over the past 400 years as we have been thawing out of the Little Ice, long before atmospheric CO2 began to rise significantly).
So let’s compare this rate (0.7°C per century) to rates of temperature increase in the past 11,300 years. Figure 5 shows rates of temperature change in the Greenland GSP2 ice core from the end of the last Ice Age through the Holocene (Figure 4A). Figure 4B shows some of the higher rates of temperature change in Figure 4A. The highest rates occurred at the transition from the Ice Age to Holocene when warming rates in Greenland were 20 to 24°F per century and the huge continental ice sheets that covered large areas of North America and Eur-Asia melted dramatically. As shown in Figure 4B, the rate for the past century (0.7°C) is puny indeed compared to late Ice Age/early Holocene rates.
Holocene rates of warming and cooling were not as profound as those at the end of the last Ice Age, but were nonetheless greater than or equal to recent warming rates. Marcott et al. contend that “If any period in time had a sustained temperature change similar to what we have today we would have certainly seen that in our record.” As shown in Figure 4A, we do indeed have a record of warming rates far in excess of those in the past century."
