Climate change news

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 https://phys.org/print456045326.html ... where we have a nice image of the hurricane taken from a video camera on the international space station ....

Living Earth

At https://phys.org/print456059321.html ... 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 https://andymaypetrophysicist.com/2018/09/06/the-great-climate-debate-re... ... which provides a link to https://andymaypetrophysicist.files.wordpress.com/2018/09/the-great-deba... ... 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 https://thebestschools.org/special/karoly-happer-dialogue-global-warming/ ... 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 https://wattsupwiththat.com/2018/08/12/the-major-change-in-the-global-wa... ... 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 https://phys.org/print451717673.html ... 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.

Cold blips in Eemian

This could be classified as geology but is really about climate - palaeoclimate. At https://wattsupwiththat.com/2018/07/23/study-abrupt-shifts-occurred-in-t... ... in a similar vein to the previous post, this concerns abrupt shifts in ancient European climate - courtesy of the University of Helsinki. Big cold snaps occurred right across the Eeemian interglacial (120,000 years ago).

Pushing a Button

Apparently, an international team of scientists have worked out how much sea levels would rise if the Larson and George VI ice shelves in the Antarctica collapsed - just a few millimetres of global sea level rise. This somewhat deflates the endles CAGW scaremongering over rising sea levels by the end of this century. Where is all the water going to come from - and these ice shelves were  chosen as they have been deemed by the doom mongers as the most likely to melt and sink into the ocean (mainly based on the fact an iceberg calved from one of them a year or so ago).

Miraculous Disposal

At https://tallbloke.wordpress.com/2018/07/16/wind-energys-big-disposal-pro... ... wind energy's big disposal problem. Germany has 28,000 wind turbines but many are nearing the end of their lives. Within the next few years a third will have been taken out of service - but disposing of them is a headache (we are told). It seems their concrete bases are 30m deep in the ground. No wonder David Bellamy was upset about wind turbines destroying the plant life of his beloved moorland habitats. The rotor blades contain glass and carbon fibre - and burning them creates toxic gases.
