Nick Cohen writes: The American Association for the Advancement of Science came as close as such a respectable institution can to screaming an alarm last week. “As scientists, it is not our role to tell people what they should do,” it said as it began one of those sentences that you know will build to a “but”. “But human-caused climate risks abrupt, unpredictable and potentially irreversible changes.”
In other words, the most distinguished scientists from the country with the world’s pre-eminent educational institutions were trying to shake humanity out of its complacency. Why weren’t their warnings leading the news?
In one sense, the association’s appeal was not new. The Royal Society, the Royal Institution, Nasa, the US National Academy of Sciences, the US Geological Survey, the IPCC and the national science bodies of 30 or so other countries have said that man-made climate change is on the march. A survey of 2,000 peer-reviewed papers on global warming published in the last 20 years found that 97% said that humans were causing it.
When the glib talk about the “scientific debate on global warming”, they either don’t know or will not accept that there is no scientific debate. The suggestion first made by Eugene F Stoermer that the planet has moved from the Holocene, which began at the end of the last ice age, to the manmade Anthropocene, in which we now live, is everywhere gaining support. Man-made global warming and the man-made mass extinction of species define this hot, bloody and (let us hope) brief epoch in the world’s history.
If global warming is not new, it is urgent: a subject that should never be far from our thoughts. Yet within 24 hours of the American association’s warning the British government’s budget confirmed that it no longer wanted to fight it. [Continue reading…]
