• Resumen

  • Gaffney examines how global temperatures, carbon dioxide levels, electric cars and Trump's coal dream would fare in 2018. Carbon dioxide in the air hits levels unprecedented in at least 800,000 years. That's an easy call, given emissions are non-zero and this gas stays aloft for centuries. What is more concerning is the rate of increase in carbon dioxide, which appears to be accelerating despite a recent dramatic slowing in emissions from human activity. The strong El Niño climate, event of 2015 and 2016 explains some of this, as it leads to drought and natural carbon release. But in 2018, with El Niño gone, scientists will be watching for signs that land and ocean stores of carbon are making things worse. On the flipside, recent record temperatures are unlikely to be repeated, thanks to a cooling La Nina, El Niño's opposite number.
