Earth's temperature likely marks hottest decade on record

The past decade is almost certain to be the hottest on record, weather experts warned on Tuesday, painting a bleak picture of vanishing sea ice, devastating heatwaves and encroaching seas in a report launched at a climate summit in Spain.

An annual assessment of the Earth’s climate by the Geneva-based World Meteorological Organization (WMO) underscored the stakes at two weeks of talks aimed at shoring up the 2015 Paris Agreement to avert catastrophic global warming.

“Heatwaves and floods which used to be ‘once-in-a-century’ events are becoming more regular occurrences,” WMO Secretary-General Petteri Taalas said in a statement.

“Countries ranging from the Bahamas to Japan to Mozambique suffered the effect of devastating  tropical cyclones. Wildfires swept through the Arctic and Australia,” he said.

Among the report’s findings:

** Average temperatures for the five-year (2015-2019) and 10-year (2010-2019) periods are almost certain to be the highest on record.

** 2019 is on course to be the second- or third-warmest year on record.

** Sea water is 26 percent more acidic than at the start of the industrial era, degrading marine ecosystems.

** Arctic sea-ice neared record lows in September and October, and Antarctica also saw record low ice several times this year.

** Climate change is a key driver of a recent rise in global hunger after a decade of steady declines, with more than 820 million people suffering from hunger in 2018.

** Weather disasters displaced millions of people this year and affected rainfall patterns from India to northern Russia and the central United States, and many other regions.
