Brace for Trump's brave new world of 1.7C global warming
https://uk.news.yahoo.com/brace-trump-brave-world-1-155338098.htmlIf 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.
