A landmark report by climate change scientists released Monday is expected to ratchet up the pressure on world leaders to rapidly end the use of polluting fossil fuels.
Some of the most important readers of the 3 949-page report by the United Nations-backed Intergovernmental Panel on Climate Change—or at least the more manageable “summary for policymakers”—will soon be headed to Glasgow, Scotland, for COP26 climate talks, also organized by the UN. In less than three months’ time, UK Prime Minister Boris Johnson will host 197 countries for negotiations aimed at limiting global temperature rise, which is already causing wildfires and flooding around the world.
Scientists on Monday warned that time is fast running out to stop global warming from exceeding 1.5 ºC, the lower end of the temperature targets agreed in Paris in 2015. Countries have agreed to submit new national pledges ramping up their ambition before COP26. At the moment, those voluntary pledges fall far short of keeping temperatures under 2 ºC, let alone 1.5 ºC, according to the UN.
Johnson urged countries to end the use of coal power, the dirtiest fossil fuel, in order to keep the 1.5 ºC limit within reach. “We know what must be done to limit global warming—consign coal to history and shift to clean energy sources, protect nature and provide climate finance for countries on the frontline,” he said on Monday, according to a statement issued by Downing Street.
Coal has been a sticking point in international negotiations meant to smooth the way to a deal in Glasgow in November. An all-night meeting of Group of 20 ministers last month in Naples, Italy, failed to produce an agreement on phasing out coal power. India was a key holdout. China, the world’s largest emitter, is also under pressure to announce a roadmap to making deep emissions cuts over the next decade. Its coal consumption is poised to hit a record this year, according to the International Energy Agency. But it’s not just poorer nations struggling with coal. At a Group of Seven leaders meeting in June, US President Joe Biden resisted a call by European countries to end the use of domestic coal power. In the end, the leaders only agreed to stop financing overseas coal projects.
The IPCC report, which Johnson described as “sobering reading,” concludes that human-made greenhouse gas emissions must be eliminated in order to limit the further global warming—and therefore further damage. “This is physics,” said Valerie Masson-Delmotte, co-chair of the report. “The only way to limit global warming is to reach net-zero carbon dioxide emissions at the global scale. The climate we experience in the future depends on our decisions now.”
But the emissions gap remains huge. The IPCC said that 2019 atmospheric CO₂ concentrations were higher than at any time in at least 2 million years.
Speaking after the launch of the report, incoming COP 26 President Alok Sharma warned that even though the world’s desire to keep 1.5 ºC within reach is clear, hope is “retreating fast.” G-20 countries must raise their aspirations on climate, he said on Monday, adding that only eight have actually tightened their emissions pledges so far.
“At COP26 we must send a clear market signal to get the transition moving faster,” Sharma said.
Getting emerging economies aligned with basic climate science will require rich countries to deliver on their decade-old pledge to mobilize $100-billion a year in financing to help poor countries invest in green technologies and adapt to rising temperatures and sea levels. The latest data from the Organisation for Economic Cooperation and Development suggests that climate aid from developed countries amounted to $78.9 billion in 2018, far short of the agreed target.
“Climate negotiations are fragile at the best of times, and ensuring that there is trust in the system is going to be vitally important,” Sharma said.
For vulnerable nations, especially those that have contributed little to historic greenhouse gas emissions, the issue of climate finance is framed around fairness. “Major emitters must take account for the damages inflicted by the fossil-fuel industry, knowing that every single ton of carbon and every single dollar spent on fossil fuels will have a negative impact,” said Ambassador Diann Black-Layne of Antigua and Barbuda, lead climate negotiator for the Alliance of Small Island States.
While many European countries have increased their climate financing, the US hasn’t kept pace. The Biden administration has pledged $5.7-billion annually beginning in 2024; the European Union, by comparison, provided $24.5 billion in 2019 alone, according to the World Resources Institute.
John Kerry, the US Special Presidential Climate Envoy for Climate, said the IPCC report signaled the need for “real action” in the 2020s. “All major economies must commit to aggressive climate action during this critical decade,” he said.
