UN climate chief Simon Stiell said, despite progress, countries were “nowhere near” cuts needed to keep rises to 1.5C this century.
Nations had agreed to act to curb warming to 2C and to aim for 1.5C over pre-industrial levels. But extreme weather events are now more common. With a plus 1.5C rise, crop damage and loss of key eco-systems such as coral reefs is expected.
Countries’ commitments will put greenhouse gas emissions up by 10.6 percent by 2030 compared to 2010 – better than last year’s forecast 13.7 percent. But the UN said carbon emissions needed to actually be cut by 45 percent in that time.
Data suggests there needs to be a near-halving (43 percent) in greenhouse gas in the next eight years to meet the 1.5C goal.
Mr Stiell said “nations have made some progress. We are still nowhere near the scale and pace of emission reductions required.
“Government decisions and actions must reflect the level of urgency…and the shortness of the time we have remaining to avoid the devastating consequences of runaway climate change.”
