Over at Political Affairs, which promises “Marxist Thought online”, an article published today warns that, according to the latest IPCC report,
Mass extinction of species is likely within 60-70 years, on a scale larger than most of the five major extinction events that have occurred in the earth’s history.
But neither of the reports issued so far this year say anything of the sort. The only mention of extinction in either of the reports are in Climate Change 2007: Impacts, Adaptation and Vulnerability – Summary for Policymakers, Working Group II:
Approximately 20-30% of plant and animal species assessed so far are likely to be at increased risk of extinction if increases in global average temperature exceed 1.5-2.5°C.
There is a risk of significant biodiversity loss through species extinction in many areas of tropical Latin America.
These largely unquantified statements are so far removed from the alarmism in Political Affairs that there seems little point going into any greater depth about the article’s scientific merit.
We can safely assume that this kind of alarmism is the way the magazine thinks the masses will be roused. But as we pointed out yesterday, there is little difference between the ways in which the left and the right stretch scientific reports beyond recognition. So what is the difference between the establishment and the revolutionaries?
