AGW claim of no MWP in the southern hemisphere is debunked ... again

At ... this post is based on a paper published last week in PNAS on research in South America and appears to show, and indeed it does show quite transparently that warmth in the northern hemisphere coincides remarkably well with lower precipitation in the Peruvian Andes. A sediment core taken from a lake displays evidence of big swings in rainfall levels.

The oceans and the climate - a new study

This story occurs at May 20th and Pierre Gosselin is faintly sarcastic in his description of a new study just published by Nature that says the oceans play a role in climate that is still not understood. In a cynical post he casts a jaundiced eye on the surprise expressed by the climate scientists - his take on their enthusiastic description of previously unknown fluctuations of currents and ocean temperatures in the tropical Atlantic.

Biogas ... the latest green dream going bottom up

The story is at May 19th, 'German Biogas plants produce deadly botulism - could be catastrophic to wildlife' - the wildlife element comes in as the story was blown by a shooting and country magazine. It seems the push to produce green electricity via biogas is looking hazardous. The lid has been kept on the subject for 10 years - by politics and by environmentalists.

The ozone hole is off the radar - why?

The discovery of an ozone hole a couple of weeks ago was all over the doomsaying news - but not anymore. Why? Its because the ozone hole has gone away (see May 18th). EM Smith suggests the ozone hole is driven by external forces such as UV from the Sun, Birkeland currents from the Sun, and possibly even cosmic ray variations. He says it seems to have nothing whatsoever to do with the distribution of gases in the upper atmosphere - such as CFCs.

Tree rings and El Ninos

Tree rings, including bristlecone pines, have been used by climate scientists as a useful took, claiming they show past temperatures. Mike Baillie, a dendrochronologist begs to differ - he has publically said they do not (and others have periodically pointed out that tree rings are affected by a variety of factors, such as precipitation rates, and where individual trees might be situated - within a forest and surrounded by aged trees, or in an open position without any competition) - and so on.


Doomsaying is a noteable feature of the medical world - report after report telling us for instance that cholesterol was a bad thing as it clogs up arteries and results in heart attacks. However, in recent months we have just got used to the idea that there is good cholesterol and bad cholesterol - and we must not eat this or that, especially certain kinds of fats. Now we have news that bad cholesterol might not be so bad after all - and is an essential of a healthy life (see ). 

Carbon - a pollutant or an essential of life?

Over at on April 29th we learn that some AGW doomsayers have said the devastating Alabama tornadoes are a result of 'C02 pollution' rather than other factors - but incredibly, at it seems that some people really do think volcanoes, earthquakes and tsunamis are induced by global warming and rising levels of C02. Worse still, some people are so convinced carbon is a pollutant they think they should try and avoid it altogether - even in food.

Follow the Dosh

This story was big on the blogosphere a year or so ago but it seems a Telegraph 'investigative' journalist has caught up with reality and cottoned on that big money lies at the root of AGW propaganda. See (and the comments are really worth reading - very illuminating) and the same story but with less genteel charm is up at which is hard hitting and from a hack of many years experience.

Oil Leaks

Oil leaks into the oceans all the time - naturally. Pierre Gosselin at a German blog, asks 'Where is the Oil? Deepwater Horizon one year later' - it seems bacteria have been feasting on the crude. The day before, April 21st, he has a spat about the five worst environmental disasters that never actually happened - in spite of the hype of doomsayers of the day. This makes you wonder about the hysteria generated over Deepwater Horizon, which had an air of irrationality inherent within the doomsayings of the day.

The Ozone Hole - an early manifestation of Global Warming doomsaying?

The environmentalists extravaganza over the so-called ozone hole in the 1970s and 1980s led to the banning of an efficient refrigerant that was replaced by an inefficient one - and millions of pounds of western subsidies found their way to countries such as China. For example, CFCs enabled one to locate a freezer in the garage if space was limited but this is not advisable with the new refrigerants hoisted on to the consumer by the green lobbyists. It all went quiet for a number of years as environmentalists switched tune and began the long-winded process of hyping AGW.
