UN chief laments 'leadership gap' ahead of climate talks

BERLIN (AP) — 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.

U.N. Secretary-General Antonio Guterres told reporters Tuesday that time is running out to cut greenhouse gas emissions to meet the goals of the 2015 Paris accord and avert global warming that could damage the planet.

“The clock is ticking,” he said in New York. “The emissions gap is the result of a leadership gap. But leaders can still make this a turning point to a greener future instead of a tipping point to climate catastrophe. ”

Guterres spoke at the launch of a new report by the U.N. Environment Programme that 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.

The report 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 in Paris climate accord of capping global warming at 2 degrees Celsius (3.6 F) compared to pre-industrial times.

The United States, the European Union and dozens of other countries have set net-zero emissions targets. However, the Environment Programme report said the net-zero goals that many governments announced ahead of a U.N. climate summit in Glasgow next week remain vague, with much of the heavy lifting on emissions cuts pushed beyond 2030.

Guterres said scientists were clear on the facts of climate change, adding that “now leaders need to be just as clear in...
