Within the next seven years, the world could undergo irretrievable change. It could emit enough greenhouse gases from fossil fuel combustion to cross the threshold for dangerous global heating in the year 2027. Or it could exceed what is supposed to be the globally-agreed target for containing catastrophic climate change − just 1.5°C above the average level for most of the last 10,000 years − a little later, in the year 2042. But on present trends, according to new research, the world is committed, whatever happens, to the crossing of its own threshold for irreversible climate change within that 15-year window. If that happens, then there is a high probability that some of the politicians and world leaders who, in Paris, in 2015, agreed an almost global accord to contain climate change to “well below” 2°C, will have to address their own failure to make it happen.

Urban regions around the world are likely to see a near-universal decrease in humidity as the climate changes, a study has found. The research suggests that building green infrastructure and increasing urban vegetation might be a safe bet for cities looking to mitigate rising temperatures. Half of the world’s population lives in urban areas, but cities only account for about 3% of global land surface. Lei Zhao, a scientist from the University of Illinois and the lead author of the paper published in Nature Climate Change, says this has meant that previous climate models have not produced data specific to cities.
