CAGW data riddled with errors

Not much to say about this one as it will be ignored by the great and the good, our masters. At ... John McLean, PhD, has produced a detailed audit that shows surface temperature datas is unfit for purpose (in the words of Anthony). This mostly concerns HadCRUT4 data sets from the Univeristy of East Anglia climate centre in Norwich. This report supports some of the sceptic arguments from over the years on data manipulation.


At ... we have an article on the decline of the puffins. In a nutshell we have a fine example of how alarmism works. It constructs a narrative that is based on doom and gloom - an entirely false case that can easily be refuted (but which the media are loathe to do for reasons only they understand). This is achieved by being economical with the truth - or in this case with actual reality.


Svante Arrhenius was a Swedish chemist (they didn't have climate scientists in his day) and he investigated the effect of doubling atmospheric carbon dioxide and how it may affect the global climate. This was read as a paper at an 1895 conference in Stockholm (and duly published). It was a defining moment for modern climate scientists of a certain persuasion that believe greenhouse gases are capable of causing catastrophic global warming. However, Arrhenius wrote his paper in an effort to understand the swings and roundabouts of the Ice Age.

Weather Balloon v Models

The recent McKitrick and Christy paper on measuring warming in the atmosphere via weather balloon data (over 60 years) in comparison to the results from modelling. The paper was written in the lead up to the next, 5th, IPCC Report on global warming (the report that keeps the alarmism on track). The latest report uses research from MCIP5 (The Coupled Model Intercomparison Project phase 5) which consists of 20 climate modelling groups, worldwide.

Heat Wave

According to Weather Eye in The Times (of London) earlier this month the recent hot weather in Europe was caused by a huge horseshe shaped pattern of sea temperatures stretching across the North Atlantic. Throughout the summer the tropical Atlantic between the Caribbean and Africa has been coller than normal - and these cool waters arched around towards the tip of Greenland. Inside the horseshoe pattern sat a large area of unusually warm water in the Mid Atlantic.

Hurricane Florence

At last, after days of media hype hurricane Florence has made landfall in North Carolina (and its wet and windy from the news pictures bounced back across the Atlantic). The danger is flooding as heavy rain is is set to continue over the weekend. This is of course a not unusual weather phenomenon. In the days leading up to land fall there was a lot of focus on the hurricane by scientists - see for example ... where we have a nice image of the hurricane taken from a video camera on the international space station ....

Living Earth

At ... Professor Timothy Lenton from Exeter university in association with French professor, Bruno Lantour, argue that humans have the potential to upgrade the planet - a Gaia version 2. The idea is that living organisms and their inorganic surroundings evolved together as a single self regulating system that has kept the planet habitable for life on earth - in spite of variations in solar energy, meteor strikes, and tectonic and volcanic activity.

Happer versus Karoly

At ... which provides a link to ... Happer versus Karoly: a climate debate. Actual debates on the greenhouse theory are very rare so this is potentially a gem. Biographies of the two participants can be found at ... this is a science debate on the subject of co2 and what it can or can't do (from two different positions).

Early IPCC reports

The Canadian climate scientist, now retired, Dr Timothy Ball, has a guest post at ... which discusses differences in the IPCC reports of 1990 and 1995 - which is going back a bit - but then he has been involved in the global warming debate for a long time (as a working climate scientist as well as a retired denier of global warming).

Brazil in LIA

At ... isotopic records obtained from caves show how rainfall distribution in Brazil was affected by the Little Ice Age (Geophysical Research Letters, July 2018). They are defining the LIA as AD1500-1850 when average temperatures were lower than at present. In the 17th and 18th centuries climate in parts of Brazil was much wetter - but in the NE is was much drier.
