“WILL GLOBAL WARMING REALLY TRIGGER MASS EXTINCTIONS?” (March 26, 2014)

Thus Der Spiegel today. “In 2007, the Intergovernmental Panel on Climate Change predicted that rising global temperatures would kill off many species,” the newspaper elaborates. “But in its new report, part of which will be presented soon, the United Nations climate change body backtracks. There is a shortage of evidence, a draft version claims.” As the article shows, the IPPC predicted in 2007 that between twenty and thirty percent of all animal and plant species faced a high risk of extinction should average global temperature rise between two and three degrees Celsius, but many uncertainties have become apparent in the meanwhile. To begin with, a large number of life forms are more adaptable than previously believed. In addition, there are many other causes of extinctions, such as monocultures, over-fertilization, and soil destruction. All together, they wipe out more species than a temperature rise of a few degrees Celsius. Given the myriad other human encroachments in the natural environment, climate change is not the only culprit of mass extinctions. And that is the gist of the article. The only remaining mystery is why that was not clear from the title and the byline in the first place. All they suggest, wrongly, is that global warming is not such a bad thing. In fact, it is a leading one among many other human encroachments in the natural environment. All things considered, it is humans who are triggering mass extinctions one way or another. Amen.
