World “nowhere near on track” to avoid warming beyond 1.5C target – “We are moving way too slowly. We have to do more of everything, faster.”

(The Guardian) – The world’s governments are “nowhere near on track” to meet their commitment to avoid global warming of more than 1.5C above the pre-industrial period, according to an author of a key UN report that will outline the dangers of breaching this limit.

A massive, immediate transformation in the way the world’s population generates energy, uses transportation and grows food will be required to limit the global temperature rise to 1.5C and the forthcoming analysis is set to lay bare how remote this possibility is.

“It’s extraordinarily challenging to get to the 1.5C target and we are nowhere near on track to doing that,” said Drew Shindell, a Duke University climate scientist and a co-author of the Intergovernmental Panel on Climate Change report, which will be unveiled in South Korea next month.

“While it’s technically possible, it’s extremely improbable, absent a real sea change in the way we evaluate risk. We are nowhere near that.”

In the 2015 Paris climate pact, international leaders agreed to curb the global temperature rise to 2C above the era prior to mass industrialization, with an aspiration to limit this to 1.5C. The world has already warmed by around 1C over the past century, fueling sea level rises, heatwaves, storms and the decline of vulnerable ecosystems such as coral reefs.

Shindell would not share exact details of the IPCC report, but he said that the more ambitious 1.5C goal would require a precipitous drop in greenhouse emissions triggered by a rapid phaseout of fossil fuels, particularly coal, mass deployment of solar and wind energy and the eradication of emissions from cars, trucks and airplanes.

Even then, emerging technology will be required on a global scale to capture emissions at the source and bury them in the ground or remove carbon directly from the air.

“The penetration rate of new technology historically takes a long time,” Shindell said. “It’s not simple to change these things. There aren’t good examples in history of such rapid, far-reaching transitions.”

The fading prospect of keeping the global temperature rise to below 1.5C has provoked alarm among leaders of low-lying island nations that risk being inundated should the world warm beyond this point.

“Every country must increase the ambition of their existing targets,” said Hilda Heine, president of the Marshall Islands, which announced a plan to reach net zero emissions by 2050 at the UN general assembly in New York this week. “If we can do it, so can everyone else.”

The UN general assembly has again pitted the world’s countries against Donald Trump when it comes to climate change, with the US president using his keynote speech to praise “clean coal”. Trump has vowed to exit the Paris accord, a stance that Emmanuel Macron, the French president, told the UN should be met with consequences such as a refusal by countries to enter into trade deals with the US.

“It’s a lot more difficult without the US as a leader in climate change negotiations,” Ola Elvestuen, Norway’s environment minister, told the Guardian. “We have to find solutions even though the US isn’t there.” […]

“We are moving way too slowly,” Elvestuen said. “We have to do more of everything, faster. We need to deliver on policies at every level. Governments normally move slowly but we don’t have the time.” [more]
