Brace for Trump’s brave new world of 1.7°C global warming.

 If you have stopped paying attention to global warming, you may soon be in
for a nasty surprise. A paper by Columbia University predicts that we will
have our first taste of a 1.7C world as soon as next year – a shock big
enough to intrude on everybody’s consciousness. One cause is the
reversion from the current cooling weather pattern of La Niña in the South
Pacific to the opposite El Niño pattern of cyclical warmth. A less
understood cause is that aerosol pollution has masked the latent heat
effect of past CO2 emissions by around 0.5C and possibly more. Carbon
lingers in the atmosphere for several hundred years. This aerosol effect is
going into rapid reverse as the world cuts toxic particulates from coal
plants, industry, cars and shipping. The Columbia estimate of 1.7C above
1880-1920 levels is at the high end of the scientific spectrum but the Met
Office, Europe’s Copernicus service and others also expect a
record-shattering year in 2027.
