MADRID : THIS decade is set to be the hottest in history, the United Nations said on Tuesday in an annual assessment outlining the ways in which climate change is outpacing humanity’s ability to adapt to it. The World Meterological Organization said global temperatures so far this year were 1.1 degrees Celsius (two degrees Farenheit) above the pre-industrial average between 1850-1900. That puts 2019 on course to be in the top three warmest years ever recorded, and possibly the hottest non-El Nino year yet. Man-made emissions from burning fossil fuels, building infrastructure, growing crops and transporting goods mean 2019 is set to break the record for atmospheric carbon concentrations, locking in further warming, the WMO said. Oceans, which absorb 90 percent of the excess heat produced by greenhouse gases, are now at their highest recorded temperatures.
The world’s seas are now a quarter more acidic than 150 years ago, threatening vital marine ecosystems upon which billions of people rely for food and jobs. In October, the global mean sea level reached its highest on record, fuelled by the 329 billion tonnes of ice lost from the Greenland ice sheet in 12 months. Each of the last four decades has been hotter than the last. And far from climate change being a phenomenon for future generations to confront, the effects of humanity’s insatiable, growth-at-any cost consumption means millions are already counting the damage.
The report said more than 10 million people were internally displaced in the first half of 2019 -- seven million directly due to extreme weather events such as storms, flooding and drought. By the end of the year, the WMO said new displacements due to weather extremes could reach 22 million. “Once again in 2019 weather and climate related risks hit hard,” said WMO Secretary-General Petteri Taalas.
“Heatwaves and floods which used to be ‘once in a century’ events are becoming more regular occurrences.” At just 1C hotter than pre-industrial times, 2019 has already seen deadly heatwaves in Europe, Australia and Japan, superstorms devastate southeast Africa, and wildfires rage out of control in Australia and California. Nations are currently in crucial talks in Madrid aimed at finalising rules for the 2015 Paris climate accord, which enjoins countries to work to limit global temperature rises to “well below” 2C..
