Climate models as ink blots

by Judith Curry

From Roger Pielke Jr.:  A fundamental problem with climate science in the public realm, as conventionally practiced by the IPCC, is the essential ink blot nature of its presentation. By “ink blot” I mean that there is literally nothing that could occur in the real world that would allow those who are skeptical of scientific claims to revise their views due to unfolding experience. That is to say, anything that occurs with respect to the climate on planet earth is “consistent with” projections made by the climate science community.

Likely causes of the recent changes in Arctic sea ice

by Judith Curry

A new paper by Polyakov, Kwok and Walsh is in press in the Bulletin of the American Meteorological Society, entitled: “Recent changes in arctic multi-year sea ice coverage and likely causes.”  This is the best paper I’ve seen on this topic, which clearly articulates the complexity of the issue.

On torturing data

by Judith Curry

although very few researchers will go as far as to make up their own data, many will “torture the data until they confess”, and forget to mention that the results were obtained by torture….

Detection of Global Economic Fluctuations in the Atmospheric CO2 Record

by Jonathan Huddleston

Current attempts by national governments worldwide to control industrial CO2 emissions following the recommendations of the IPCC could be viewed within the scientific paradigm as the projection of a large scale experiment on the earth’s climate system to validate the hypothesis that anthropogenic CO2 emissions through the burning of fossil fuels and land use changes (inter alia) are a major factor driving climate change. If such policies are to be effective,  it is hypothesized here that periodic global economic and industrial fluctuations in activity of sufficient magnitude should be capable of producing a signal detectable by atmospheric CO2 monitoring programmes.

Weather weirding: back to the 1950’s

by Judith Curry

Seth Borenstein at AP published an article  entitled “Nature’s extremes worse than usual in US this year.”  I have a quote in the article:

Judith Curry of Georgia Tech disagreed, saying that while humans are changing the climate, these extremes have happened before, pointing to the 1950s.  “Sometimes it seems as if we have weather amnesia,’’ she said.

Here is a more complete context for that quote.
