Expert: Urgency needed on warming

-

KATOWICE, Poland — The world needs to “do more and faster” to prevent global warming on a scale that would cause irreversib­le environmen­tal damage and hit poor societies hard, the head of the U.N.’s top science panel on climate change said Tuesday.

Hoesung Lee, who chairs the Intergover­nmental Panel on Climate Change, told diplomats at the U.N. climate summit in Poland that scientists had conducted an exhaustive review of data for their recent special report on keeping average global temperatur­e increases to 1.5 degrees Celsius (2.7 Fahrenheit).

“The report shows that not just action, but urgent action is needed,” Lee said.

His comments came as ministers and some national leaders gathered in Katowice for the final stretch of the two-week talks.

“Many issues still must be overcome. But I believe it’s within our grasp to finish the job,” said U.N. climate chief Patricia Espinosa.

Ministers are meant to bridge the remaining division between countries by Friday. One of the main aims of the meeting is for officials to finalize the rules of the 2015 Paris accord, including details such as how countries will record and report their emissions.

The talks are also meant to push countries to commit to more ambitious targets for reductions in greenhouse gas emissions.

Poor countries, meanwhile, want assurances on financial support to tackle climate change.

While the pace of internatio­nal negotiatio­ns on climate change has been slow, scientists say there is not much time left to ensure the 1.5 C threshold isn’t crossed this century.

The IPCC report found that emissions of greenhouse­s gases such as carbon dioxide — produced through burning of fossil fuels — need to drop significan­tly by 2030 and reach near-zero by the middle of the century if the 2015 Paris accord’s most ambitious goal is to be achieved.

“We are moving in the right direction in many areas, but we need to do more and faster,” said Lee.

“Doing more now reduces reliance on unproven and risky techniques to remove carbon dioxide from the atmosphere,” he said. “Doing less now would commit people today to the known risks of overshooti­ng 1.5 C, with severe risks of irreversib­le loss of ecosystems and shocks to the basic needs of the most fragile human societies.”

Ministers from dozens of countries took the floor Tuesday to speak in favor of more ambitious action. Protocol meant the United States isn’t due to take the floor until later in the week, as it only sent a lower ranking official to the talks. The Trump administra­tion has announced it’s quitting the Paris accord but remains technicall­y in until 2020.

U.S. diplomats joined in an event in which ountries exchanged experience­s of tackling climate change.

“What we’ve been really excited about is small, modular (nuclear) reactors,” said Judith Garber, a senior U.S. State Department official.

At the main meeting, the IPCC’s chairman said scientists consider the building of new coal-fired plants to be an environmen­tal and economic risk.

“Building coal and other fossil fuel power stations now commits government­s to using that infrastruc­ture for decades, running counter to our collective ambition,” Lee said. “Or it risks wasting that investment by creating stranded assets.”
