2010s hottest decade in history, UN says as emissions rise again

This decade is set to be the hottest in history, the United Nations said 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.
