In the study, scientists from the Potsdam - based Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, and Harvard University show that sea surface temperatures reconstructed from
climate archives vary to a much greater extent on long time scales than simulated
by climate models.

This approach is a natural fit for
climate science: a single run of a high - resolution
climate model can produce a petabyte of data, and the
archive of
climate data maintained
by the UK Met Office, the national weather service, now holds about 45 petabytes of information — and adds 0.085 petabytes a day.
As with most papers

by Baliunas & Soon:
Take some representative set of
climate models predicting the
climate at the end of the 21st century given some scenario of emissions (for example the 20 models in the

The piece caught my eye because, in sifting through New York Times
archives a few years ago while researching my book on the changing Arctic, I found what I believe is our first substantial newspaper coverage of research pointing to the prospect that humans could substantially warm the
climate — a 1956 article on Plass's work
by Waldemar Kaempffert.
Recently I have been looking at the
climate models collected in the CMIP3
archive which have been analysed and assessed in IPCC and it is very interesting to see how the forced changes — i.e. the changes driven the external factors such as greenhouse gases, tropospheric aerosols, solar forcing and stratospheric volcanic aerosols drive the forced response in the models (which you can see
by averaging out several simulations of the same model with the same forcing)-- differ from the internal variability, such as associated with variations of the North Atlantic and the ENSO etc, which you can see
by looking at individual realisations of a particular model and how it differs from the ensemble mean.
There are some earlier pieces in The Times, found
by searching the Times Machine
archive for «coal,
climate, atmosphere» and the like, but nothing quite this direct.
Standard experiments, agreed upon

Whilst I failed to persuade GRL to require Forest to provide any verifiable data or computer code, he had a change of heart — perhaps prompted
by the negative publicity at
Climate Etc — and a month later
archived the complete code used for Forest 2006, along with semi-processed versions of the relevant MIT model, observational and AO - GCM control run data — the raw MIT model run data having been lost.
«Researchers first became intrigued

climate change and techniques for observing it.
Spend even the briefest effort doing a combined internet search of the words «Exxon» and «
climate change», and it becomes abundantly obvious that enviro - activists have long believed Exxon is a fundamental threat to the planet (full

climate denial machine (full text here) over the last decade — has been tapped
by President - elect Trump to be Secretary of State, we should be terrified of him.
«Researchers first became intrigued

climate records include abrupt changes that are smaller and briefer than in paleoclimate records but show that abrupt
climate change is not restricted to the distant past.»
In addition, many libraries and
archives are digitizing their collections, ensuring that anything destroyed
by climate change continues to exist in pixels, if not on vellum and parchment and paper.
The models in both graphs are represented

In this particular area of
climate change, many of the assertions made
by respectable scientists in peer reviewed literature are not backed up
by archived data, code and other materials, and long legal battles have been fought to get those essential pieces of information put out for scrutiny.
But back in the summer of 2009 — stop the presses — Kert Davies himself gave us the same «breaking news» about Dr Soon's funding at the Huffington Post (

For earlier times, we adopt Greenland temperature estimated as follows (33): For the period 128,700 B.P. to 340,000 B.P., this temperature was derived from a proxy based on Antarctic ice core methane data using the relation T = − 51.5 + 0.0802 [CH4 (ppb)-RSB- from a linear regression of Greenland temperature estimates on Antarctic methane for the period 150 B.P. to 122,400 B.P.. For the remaining period of 122,400 B.P. to 128,700 B.P., data from a variety of
climate archives indicate that Greenland warming lags that of Antarctica, with rapid warming commencing around 128.5 ky B.P. in the northern North Atlantic and reaching full interglacial levels
by about 127 ky B.P. (51).

When the 2002
Climate Action Report was posted on the old, now discontinued, EPA global warming site (although it is still archived via a link), its discussion of climate change impacts was honest enough to provoke media notice that the administration found embarrassing, prompting the President to dismiss it as «a report put out by the bureaucracy.
