You can't make it up XCV - the Guardian insults the intelligence of the global warming movement (31 mar 17)


"Rising temperatures on land and sea are increasingly forcing species to migrate to cooler climes, pushing disease-carrying insects into new areas, moving the pests that attack crops and shifting the pollinators that fertilise many of them, an international team of scientists has said."

"Species" includes more than "disease-carrying insects" and "pests". Aren't there any useful species being "pushed into new areas"?

"This mass movement of species is the biggest for about 25,000 years, the peak of the last ice age, say the scientists, who represent more than 40 institutions around the world."

If that's true, it only shows how much these "institutions" have been corrupted by the global warming industry. The claim is obviously false.

During the last "ice age" ("glacial period", to be precise), Britain and Ireland were mostly glaciated, as was all of Scandinavia. The ice covered Canada and extended south to the Missouri and Ohio Rivers, and east to Manhattan.

When the ice melted around 12 thousand years ago, it had dramatic effects. Sea levels rose by over 100m, isolating and shrinking islands, to the detriment of people who'd reached them when sea levels were lower. Of course, tropical species moved north. New species evolved. Some of them good, some not so good - but on balance, warming has been beneficial.

"By 5000 to 3000 BC average global temperatures reached their maximum level during the Holocene and were 1 to 2 degrees Celsius warmer than they are today. Climatologists call this period either the Climatic Optimum or the Holocene Optimum.

During the climatic optimum many of the Earth's great ancient civilizations began and flourished. In Africa, the Nile River had three times its present volume, indicating a much larger tropical region. 6,000 years ago the Sahara was far more fertile than today and supported large herds of animals." - 'The Climate of the Holocene', Arizona University

The movement of species today is not the largest since the peak of the last glacial period - there has been at least one time - the end of the last glacial period - when it has been much greater, when Britain, Canada, Scandinavia, and large areas of Russia, South America and Central Asia became habitable.
