Brr...

First the Canadians. Now the Brits. We're not warming up, they say. We may be entering a mini Ice Age.

There has been no temperature increase in the last 15 years.

You may recall that we wrote about the sun's low magnetic activity portending an ice age three years ago. Sunspot numbers reveal activity, and "sunspot numbers are running at less than half those seen during cycle peaks in the 20th century". Projections are said to be lower.

Historical precedents for another very cold period include the Dalton minimum of 1790 to 1830 and the Maunder minimum between 1645 and 1715. They were named after British scientists who identified them. The suggested reasons for the cold decades were volcanism in the first case and reduced solar activity in the second.

"Nathan Gillett and his co-workers at Environment Canada in Victoria, British Columbia, analyzed how well the latest Canadian Earth System Model tracked temperature changes attributable to volcanoes, man-made aerosols and rising greenhouse-gas emissions." It's noteworthy that "they adjusted the model using temperature records from 1851 to 2010 — 60 years of data more than most previous analyses".

Scientists using all the data available to them and not just cherry-picking convenient facts. . . what would Al Gore say?

This recent article in the Wall Street Journal, signed by scientists, explains why an increasing number of them don't believe in global warming.

There's no point in tilting at windmills when we have real environmental problems to tackle.
