Guardian Reports: +1.5C Global Warming Goal Illusory, as NOAA Publishes “State of the Climate 2015” Report

August 7, 2016

Writing in The Guardian, Robin McKie reports (August 6th, 2016) that climatologists are warning that the +1.5C global warming target informally adopted by the “breakthrough” Paris Agreement signed at COP21 last year is already very close to being broken.  McKie cites data from “Ed Hawkins of Reading University show[ing] that average global temperatures were already more than 1C above pre-industrial levels for every month except one over the past year and peaked at +1.38C in February and March.”  The Potsdam climatologist Joachim Schellnhuber is then quoted, delineating a radical vision for averting the +1.5C goal, one that is entirely contradictory to the exigencies of the capitalist mode of production:

“It means that by 2025 we will have to have closed down all coal-fired power stations across the planet. And by 2030 you will have to get rid of the combustion engine entirely. That decarbonisation will not guarantee a rise of no more than 1.5C but it will give us a chance. But even that is a tremendous task.”

McKie closes by raising the possibility that the world may well overshoot the 1.5C target but then retroactively calm planetary overheating using negative-emissions technologies.  How this would happen is not made very clear.

In parallel, on 2 August, Oliver Milman writes about the National Oceanic and Atmospheric Administration’s (NOAA) newly released “State of the Climate Report 2015,” which details the “’toppling of several symbolic mileposts’ in heat, sea level rise and extreme weather in 2015.”  These include the overall record heat experienced in 2015, both atmospherically and in the oceans–with the eastern Pacific Ocean being subjected to record heat of +2C, and the Arctic experiencing a similar record-shattering increase of +8C–as well as record sea level rise and the lowest-ever recorded Arctic sea-ice minimum.  These alarming planetary symptoms correspond in turn to the record CO2 atmospheric concentration of 400ppm.  Milman notes as well the Met Office scientist Kate Willett’s observation that “there was a 75% annual increase in the amount of land that experienced severe drought last year.”

Guardian: “World’s oceans facing biggest coral die-off in history, scientists warn”

In an 8 October column for the Guardian, Karl Mathiesen reports on scientific findings regarding the current third global coral-reef bleaching event, due principally to a “a massive underwater heatwave, driven by climate change,” and intensified by this year’s strong El Niño Southern Oscillation (ENSO).  The previous two global bleaching events took place in 1998 and 2010 (both also ENSO years), but Dr Mark Eakin, coordinator of the US National Oceanic and Atmospheric Administration Coral Reef Watch program, fears that this current episode may be the worst yet, as 2015 and 2016 are expected to be the hottest years ever recorded–in keeping with the profoundly alarming warming trajectory for which global capitalism is responsible.  The major differences between the current bleaching episode and the two prior ones have to do with the now-higher baseline temperature of the oceans and the longer duration of excess heat to which coral are exposed.  As Professor Ove Hoegh-Guldberg observes, “It’s like a hospital patient. If you’ve got a chronic disease then you are more sensitive to a lot of other things and if you want a recovery then you need to take all those other stresses off.” These symptoms are now evident in a 4,600 square mile region of the Atlantic, Pacific, and Indian oceans, as well as the Caribbean sea.

Coral reefs comprise 0.1% of the ocean floor and support a quarter of all marine species.

These distressing news come just as the Climate Action Tracker (CAT) concludes that, even if all UN member-states somehow fulfilled the considerably weak carbon-reduction pledges they have put forth for the upcoming Paris climate talks (COP21), global temperatures would soar far beyond the internationally “accepted” 2C limit above the temperatures that prevailed during pre-industrial times.
