Professor Anastasios Tsonis, [Meteorologist] of the University of Wisconsin, said: “We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.”

Dear Professor Anastasios Tsonis,
The internet is all a buzz with a quote that is being credited to you.
“We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.”
Is that an accurate reflection of what you believe?
If it is, may I ask: Weren’t the 2000s the warmest decade on record? Where does that claim leave the matter of GHGs and the imbalance in Earth’s radiative budget? What about the heat that is being absorbed by the oceans?
Thank you for your time and hopefully interest

the reply

Dear Peter
Yes this my quote.
As for your question: at the end of the century we were sitting on the highest global temperature value of the modern record. Since then we have leveled off and we may in fact be cooling. “We have reached the top of the mountain”, therefore it’s not surprising that the last decade is one of the warmest on record. Think about it!  The important aspect is that the warming of the 80s and 90s has stopped and the models missed it completely! The important issue is that we have entered a new regime in global temperature tendency. In fact, I find it very misleading that scientists will present “the warmest decade” argument to justify their beliefs (or failures).
Regarding the oceans absorbing heat, it is another argument without solid proof.

From that bastion of scientific truth the GWPF reports the latest science news from .. John Roberts, Fox News
[1st Oct 2013 – in response to the IPCC AR5 – with regard to the slowing in warming]

Anastasios Tsonis, distinguished professor at the University of Wisconsin – Milwaukee, believes the pause will last much longer than that. He points to repeated periods of warming and cooling in the 20th century.“Each one of those regimes lasts about 30 years … I would assume something like another 15 years of leveling off or cooling,” he told Fox News.

That goes well beyond the window the IPCC has acknowledged, which Tsonis and other scientists believe will significantly change the predictions for temperature rise over the next century.

“I know that the models are not adequate,” Tsonis told Fox News. “There are a lot of climate models out there. They don’t agree with each other – and they don’t agree with reality.”

In fact, the IPCC’s massive, complex new report acknowledges that none of the models predicted the hiatus. The authors write that it could be due to climate models over-predicting the response to increasing greenhouse gases, or a failure to account for water vapor in the upper atmosphere.

The bottom line – no one saw it coming.

“Almost all historical simulations do not reproduce the observed recent warming hiatus,” the report states.

The claim that we have entered a cooling phase dates back to 2009 as co author:- Swanson, K.L. and A.A. Tsonis, 2009: Has the climate recently shifted? Geophysical Research Letters, 36 the paper and explanation are available as a guest post by Kyle Swanson with the non sceptical realclimate blog

What we find is that when interannual modes of variability in the climate system have what I’ll refer to as an “episode,” shifts in the multi-decadal global mean temperature trend appear to occur. I’ll leave the details of these episodes to interested readers (here and here), as things get pretty technical. It’s sufficient to note that we have an objective criteria for what defines an episode; we aren’t just eyeballing curves. The climate system appears to have had three distinct “episodes” during the 20th century (during the 1910′s, 1940′s, and 1970′s), and all three marked shifts in the trend of the global mean temperature, along with changes in the qualitative character of ENSO variability. We have also found similar types of shifts in a number of model simulations (both forced and unforced) that were run in support of the IPCC AR4 report.

The contentious part of our paper is that the climate system appears to have had another “episode” around the turn of the 21st century, coinciding with the much discussed “halt” in global warming. Whether or not such a halt has really occurred is of course controversial (it appears quite marked in the HadCRUT3 data, less so in GISTEMP); only time will tell if it’s real. Regardless, it’s important to note that we are not talking about global cooling, just a pause in warming.

What do our results have to do with Global Warming, i.e., the century-scale response to greenhouse gas emissions? VERY LITTLE, contrary to claims that others have made on our behalf. Nature (with hopefully some constructive input from humans) will decide the global warming question based upon climate sensitivity, net radiative forcing, and oceanic storage of heat, not on the type of multi-decadal time scale variability we are discussing here. However, this apparent impulsive behavior explicitly highlights the fact that humanity is poking a complex, nonlinear system with GHG forcing – and that there are no guarantees to how the climate may respond.

Back in 2009 A Tsonis was not predicting global cooling. In September 2013 he is quoted in David Rose article in the Mail

Professor Anastasios Tsonis, of the University of Wisconsin, was one of the first to investigate the ocean cycles. He said: ‘We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped. The IPCC claims its models show a pause of 15 years can be expected. But that means that after only a very few years more, they will have to admit they are wrong.

The article is copied in the Telegraph by Hayley Dixon a rebuttal to the ‘ice is recovering’ ‘it’s cooling’ can be found at Carbonbrief

The Mail article is recycled material by Rose from January 2010 where he quotes Tsonis

Prof Anastasios Tsonis, head of the University of Wisconsin Atmospheric Sciences Group, has recently shown that these MDOs move together in a synchronised way across the globe, abruptly flipping the world’s climate from a ‘warm mode’ to a ‘cold mode’ and back again in 20 to 30-year cycles.

‘They amount to massive rearrangements in the dominant patterns of the weather,’ he said yesterday, ‘and their shifts explain all the major changes in world temperatures during the 20th and 21st Centuries. ‘We have such a change now and can therefore expect 20 or 30 years of cooler temperatures.’ Prof Tsonis said that the period from 1915 to 1940 saw a strong warm mode, reflected in rising temperatures.

Prof Tsonis said, last week 56 per cent of the surface of the United States was covered by snow. ‘That hasn’t happened for several decades,’ he pointed out. ‘It just isn’t true to say this is a blip. We can expect colder winters for quite a while.’ He recalled that towards the end of the last cold mode, the world’s media were preoccupied by fears of freezing. For example, in 1974, a Time magazine cover story predicted ‘Another Ice Age’, saying: ‘Man may be somewhat responsible – as a result of farming and fuel burning [which is] blocking more and more sunlight from reaching and heating the Earth.’

Prof Tsonis said: ‘Perhaps we will see talk of an ice age again by the early 2030s, just as the MDOs shift once more and temperatures begin to rise.’

…..Prof Tsonis is not a climate change ‘denier’. There is, he said, a measure of additional ‘background’ warming due to human activity and greenhouse gases that runs across the MDO cycles. But he added: ‘I do not believe in catastrophe theories. Man-made warming is balanced by the natural cycles, and I do not trust the computer models which state that if CO2 reaches a particular level then temperatures and sea levels will rise by a given amount.’These models cannot be trusted to predict the weather for a week, yet they are running them to give readings for 100 years.’ Prof Tsonis said that when he published his work in the highly respected journal Geophysical Research Letters, he was deluged with ‘hate emails’. He added: ‘People were accusing me of wanting to destroy the climate, yet all I’m interested in is the truth.’ He said he also received hate mail from climate change sceptics, accusing him of not going far enough to attack the theory of man-made warming.

Mediamatters following the most recent Mail article contacted Tsonis on the issue of entering a new ice age:-

The Mail on Sunday*, as well as many subsequent accounts, also cited the remarks of a meteorologist, Anastasios Tsonis, about a “cooling trend” as evidence that scientists are “forecast[ing] an imminent ice age.” But in emails to Media Matters, Tsonis said that he had “never made a statement that the long-term warming has stopped” and that some media claims “differ[ed] greatly” from his statements (typos edited for clarity):

The media print titles from statements that differ greatly from the statements. My statement was that the warming of the 80s and 90s has stopped and it is likely according to our research that the planet will be cooling for the next 10-15 years. This is far from going to ice ages!!!

He added that he feels climate change is “an important issue for now and the future but we need to understand it better.”
