“The report confirms the utterly glacial pace of climate action, despite the looming precipice of climate tipping points we’re approaching,” said climate scientist Bill Hare, head of Climate Analytics that also examines what countries are promising and doing about carbon emissions in its own analysis.
Instead of limiting warming to 1.5 or 2 degrees Celsius above pre-industrial levels, the global goals set by 2015 Paris agreement, the way the world is acting now, warming will hit 2.8C by the year 2100, the UN report said. Countries’ concrete pledges would bring that down to 2.6C. It’s already warmed 1.1C since pre-industrial times.
“In all likelihood we will pass by 1.5,” UNEP executive director Inger Andersen told The Associated Press in an interview. “We can still do it, but that means 45 per cent emissions reductions” by 2030.
World Meteorological Organisation Secretary-General Petteri Taalas said the UN weather agency has calculated there’s a 50 per cent chance the world will likely hit the 1.5C mark temporarily in the next five years and “in the next decade we’d be there on a more permanent basis”.
“It’s really about understanding that every little digit (tenth of a degree of warming) that we shave off is a lesser catastrophic outlook,” Andersen said.
“We’re sliding from climate crisis to climate disaster,” Andersen said in a Thursday news conference.
The emissions gap is the difference between the amount of carbon pollution being spewed between now and 2030 and the lower levels needed to keep warming to 1.5C or 2C.
“The emissions gap is a by-product of a commitments gap. A promises gap. An action gap,” Guterres said.
Stanford University climate scientist Rob Jackson, who chairs the independent Global Carbon Project that tracks carbon dioxide emissions around the world but wasn’t part of the UN report, said “another decade of fossil emissions at current rates and we’ll zip past 1.5C... The way things are going though we’ll zip past 1.5C, past 2C and - heaven help us - even 2.5 or 3C.”
“We’re failing by winning too slowly,” Jackson said in an email. “Renewables are booming and cheaper than ever. But Covid stimulus plans and the war in Ukraine have disrupted global energy markets and led some countries (to) revert to coal and other fuels. This can’t continue in a safe climate.”
In 10 days, yearly international climate negotiations will begin in Sharm El Sheikh, Egypt, and in the run-up to the United Nations conference, several reports highlight different aspects of the world’s battle to curb climate change.
Yesterday, a different UN agency looked at countries’ official emission reduction targets. Today’s Emissions Gap report looks at what countries are actually doing as well as what they promise to do in the future in various pledges.
The G20 nations, the richest countries, are responsible for 75 per cent of the heat-trapping pollution, Andersen said, adding “clearly the more those G20s lean in, the better we will be”.
The report said “G20 members are far behind in delivering” on their promises to reduce emissions. Taking out the special cases of Turkey and Russia, current polices by G20 nations fall 2.6 billion metric tons a year short of the 2030 goal, the report said. Both Turkey and Russia’s targets for 2030 have higher pollution levels than current policies project and using their projections would make the G20 emissions gap artificially low, the report said.
“It’s critical that China, as well as the US and other G20 countries, actually lead,” Andersen said.
She hailed the newly passed $375 billion American climate- and inflation-fighting law as an example of action instead of just promises.
The report said that by 2030 the US law should prevent 1 billion metric tons of carbon emissions, which is much more than other nations’ efforts made this year.
“What we’re calling for is an accelerated pace because there are good things happening out there in a number of countries, but it’s just not fast enough and it’s not consistent enough,” Andersen said.
Overall, to get to the emission cuts needed, the world needs to transform to a low-carbon economy, something that needs global investments of $4 trillion to $6 trillion a year, the report said.
