The continuing furore caused by The
Mail on Sunday’s revelations – which will now be amplified by the return
of the Arctic ice sheet – has forced the UN’s climate change body to hold a crisis meeting.
The UN Intergovernmental Panel on Climate Change (IPCC) was due in October to
start publishing its Fifth Assessment Report – a huge three-volume
study issued every six or seven years. It will now hold a pre-summit in
Stockholm later this month.
Leaked documents show that governments which support and finance the IPCC are demanding more than 1,500 changes to the report’s ‘summary for policymakers’. They say its current draft does not properly explain the pause.
At the heart of the row lie two questions:
the extent to which temperatures will rise with carbon dioxide levels,
as well as how much of the warming over the past 150 years – so far,
just 0.8C – is down to human greenhouse gas emissions and how much is
due to natural variability.
In
its draft report, the IPCC says it is ‘95 per cent confident’ that
global warming has been caused by humans – up from 90 per cent in 2007.
She pointed to long-term cycles in ocean temperature, which have a huge influence on climate and suggest the world may be approaching a period similar to that from 1965 to 1975, when there was a clear cooling trend. This led some scientists at the time to forecast an imminent ice age.
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.’
Others are more cautious. Dr Ed Hawkins, of Reading University,
drew the graph published by The Mail on Sunday in March showing how far
world temperatures have diverged from computer predictions. He admitted
the cycles may have caused some of the recorded warming, but insisted
that natural variability alone could not explain all of the temperature
rise over the past 150 years.
.
Nonetheless, the belief that summer Arctic ice is about to disappear remains an IPCC tenet, frequently flung in the face of critics who point to the pause.
Yet there is mounting evidence that Arctic ice levels are cyclical.
Data uncovered by climate historians show that there was a massive melt
in the 1920s and 1930s, followed by intense re-freezes that ended only
in 1979 – the year the IPCC says that shrinking began.
Professor Curry said the ice’s behaviour over the next five years would
be crucial, both for understanding the climate and for future policy.

A BBC discussion suggests a pause in confiscation of taxpayer dollars for CO2 induced terror that’s not happening. Temperatures have remained flat since 1998 while CO2 has increased globally (though US CO2 emissions have plunged). Billions of taxpayer dollars were diverted based on predictions that didn’t happen which “peer reviewed literature regards as established yet unexplained:“
7/22/13, “Andrew Neil on Ed Davey climate change interview critics,” BBC, Andrew Neil
.
Multi-billion dollar “spending decisions, paid for by consumers and taxpayers…might not have been taken (at least to the same degree or with the same haste) if global warming was not quite the imminent threat it has been depicted….The recent standstill in global temperatures is a puzzle. Experts do not know why it is occurring or how long it will last....There is no consensus.
.
Extensive peer-reviewed literature regards it as established yet unexplained. It is widely accepted that the main climate models which inform government policy did not predict it.”...(subhead, “Reputable evidence”)
.
For many climate scientists the plateau – which may or may not have long-term significance – has come as something of a surprise.
Recently Nature, which has published extensively on global warming, called it one of climate science’s greatest mysteries.
So it is legitimate to ask if the government takes the pause seriously and if it has any implications for policy ie, if there is a pause in warming, is there a case for the government to pause or slowdown its expensive efforts to decarbonise the economy until the picture becomes clearer?…
We wanted to stick with the metric that most viewers would understand and which has been used most to judge the course of global warming in public debate i.e. surface temperatures, which are central to the science and, for viewers, the principle point of interest.
At the Sunday Politics we are also used to public figures who try to change the metric when the one they’ve put their faith in does not behave as expected. We try not to let that happen.
Moreover, the purpose of the interview was not to question all aspects of climate science, just the one metric that has commanded most attention. Other possible indicators of climate change – ice melt, ocean temperatures and extreme weather events – are a matter of widespread debate in which the science most certainly is not “settled”.
.
For example, trends in Arctic ice decline and ocean warming are not necessarily irrefutable evidence of continued global warming, though many climate scientists believe they are indeed caused by global warming.
Others point out that satellite observations began in 1979 and caught a decline in Arctic ice already in progress. So the origin of the decline could be many decades ago, and might not have been started by man (though global warming could now be exacerbating a previous “natural” melting trend).
There is evidence of great variability in sea ice in the Arctic from historical records and old newspaper cuttings from decades ago reporting the disappearance of the ice.
A new paper by the Danish Meteorological Institute (DMI) suggest that Greenland ice sheet melting is related to solar activity and “a considerable fraction of the current withdrawal could be a natural occurrence”….
There
is a huge debate in climate science over the relationship between global
warming and ocean temperatures. As pointed out above some
scientists…believe that global warming is causing the depths of the oceans to heat up and that one day this heat will be released.
This is widely contested and even, by some, dismissed. The data is short-lived and contentious (the “warming” at depths of many hundreds of metres is being measured in hundredths of a degree C). We did not have time to go there in the interview.
We stuck to the advice of Professor Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology and a world authority on global warming, that: “… the best (most mature, highest quality) data set for inferring recent climate change is the surface temperature data record.”…
Our focus was on a global temperature plateau which could be a challenge to the forecasts of climate models which have determined government policy. The plateau could continue for the foreseeable future or melt away as temperatures resume their upward trajectory.”…

“The British Met Office forecast even more recently that the temperature interval could continue at a high level until the end of 2017 – despite the rapidly increasing emissions of greenhouse gases. Then global warming would pause 20 years.”…”The exact reasons of the temperature standstill since 1998, are not yet understood, says climate researcher Doug Smith of the Met Office.“…

Comment: Trillions of dollars have been stolen from US taxpayers and given to CO2 terror profiteers over the past 20-30 years
in the greatest money-making scam of all time. Real problems
were neglected so that millionaires, billionaires, UN parasites, and the
UK monarchy could get richer at the expense of the poor and the middle
class. CO2 terror has never been more than an idea. Entire industries
formed around something that doesn’t exist. A generation of humanity
wasted. A new commodity trading market was created to “trade CO2.”
Academia has benefited hugely from the idea of CO2 terror. They took
billions of taxpayer dollars for something that doesn’t exist. Things
will be different in academia when the CO2 gravy train finally ends.
People like George Bush #1 should be in jail for pushing this scam. CO2 terror spending began before him but he enshrined it, enslaved US taxpayers to it, enslaved at least 13 federal agencies
to it. At minimum, US CO2 spending must cease immediately. Billionaire
CO2 terror profiteers like Bloomberg, Steyer, Soros, Prince Charles, et
al. are obsessed with bullying humanity into committing genocide on
itself. They need to get a life or check into a hospital for the
criminally insane.

UN climate official Edenhofer freely admits the global warming movement is about redistribution of wealth:
.
11/14/10: “”But one must say clearly: We distribute by climate policy de facto the world’s wealth around. …This has to do with environmental policy… almost nothing.…The climate summit in Cancun end of the month is not a climate conference, but one of the largest economic conferences since the Second World War.”…
