Sharjah 24 – BNA: The head of the United Nations says a “leadership gap” is undermining the world’s efforts to curb global warming, days before presidents and prime ministers from around the globe gather for a climate summit in Glasgow, reports AP.
UN Secretary-General Antonio Guterres told reporters Tuesday that time is running out to cut greenhouse gas emissions and meet the goals of the 2015 Paris accord to avert global warming that he said could become “an existential threat to humanity.”
“The clock is ticking,” he said in New York at the presentation of a UN report highlighting the difference between what scientists say is needed and what countries are doing to reduce the amount of greenhouse gas being pumped into the atmosphere.
“The emissions gap is the result of a leadership gap,” Guterres said. “But leaders can still make this a turning point to a greener future instead of a tipping point to climate catastrophe.”
The new report by the UN Environment Programme found fresh pledges by governments to cut emissions are raising hopes but aren’t strict enough to keep global warming from exceeding 1.5 degrees Celsius (2.7 degrees Fahrenheit) by the end of the century.
It concluded that recent announcements by dozens of countries to aim for “net-zero” emissions by 2050 could, if fully implemented, limit a global temperature rise to 2.2 degrees Celsius (4 F).
That’s closer but still above the less stringent target agreed upon in the Paris climate accord of capping global warming at 2 degrees Celsius (3.6 F) compared to pre-industrial times.
The European Union, the United States and dozens of other countries have set net-zero emissions targets. However, the UNEP report said the net-zero goals that many governments announced ahead of a UN Climate summit in Glasgow next week remain vague, with much of the heavy lifting on emissions cuts pushed beyond 2030.
