World falling ‘dangerously short’ on climate action, UN chief warns

PARIS –

chief → fall → action
Global commitments to cut planet-heating emissions are falling far short of the Paris climate goals and put the world on course for 2.6 deg C warming this century, the UN warned on Oct 21.
asserted
UN → cut → Oct
The report by the United Nations Environment Programme (UNEP) lays bare the chasm between rhetoric and action when it comes to tackling global warming, and the challenge before political leaders at November’s COP31 climate summit.
asserted
it → lay → summit
Even if countries deliver their latest climate pledges in full, global temperatures could still rise 2.6 deg C above pre-industrial levels by 2100, said the annual Emissions Gap Report.
uncertain
Report → deliver → 2100
That would blow past the historic goal agreed in 2015 in Paris: keeping warming well below 2 deg C while striving for a safer 1.5 deg C.
asserted
That → blow → C
Any chance of keeping to 1.5 deg C has been “lost” due to decades of insufficient action, the report said.
asserted
report → keep → action
“The world can no longer avoid overshooting the 1.5 degree limit, and the consequences are already devastating,” said UN chief Antonio Guterres in a statement to launch the closely watched report.
asserted
Guterres → avoid → report
“Deadly floods, brutal heatwaves, raging wildfires, lost lives, crippled economies, deepening inequalities, and those least responsible are suffering first and worst,” he said.

Overall, global greenhouse gas emissions in 2025 were broadly on a par with record levels in 2024, with the difference between the two years too small to call, the report said.
asserted
report → call → years
Carbon emissions just from burning coal, oil and gas – the main driver of climate change – rose slightly in 2025 compared to the previous year.
asserted
emissions → burn → year
Guterres said deep and immediate cuts were needed to protect humanity from worsening impacts, but instead “emissions remain at record levels, and national climate plans and current policies fall dangerously short”.
asserted
plans → say → levels
Sticking just with current policies would see warming hit 2.8 deg C by the end of the century, the report said.
asserted
report → stick → century
Scientists warn that every additional fraction of a degree above 1.5 deg C increases extreme weather events and the likelihood of irreversible changes to the planet, from dying coral reefs to melting permafrost.
asserted
fraction → warn → permafrost
The world has already warmed roughly 1.4 deg C relative to pre-industrial times, and crossing 1.5 deg C is expected in a matter of years.
asserted
crossing → warm → years
This latest UNEP warming outlook is worse than in 2025 because of the formal withdrawal of the United States from the Paris accord and upward revisions of historical emissions, said report co-author Anne Olhoff.
asserted
Olhoff → say → emissions
Emissions growth slowed among the G-20, but the US was a “major exception”, it added.
asserted
it → slow → G-20
The Group of 20 major economies (G-20) accounts for three-quarters of global emissions.
asserted
Group → account → emissions
Among the world’s top six emitters, preliminary data for 2025 showed emissions increases in the US, Indonesia and China, and decreases in India, Russia and the European Union.
asserted
data → show → India
But the US increase of 133 megatonnes of carbon dioxide equivalent “far exceeded” that of any other country, driven by higher electricity demand and a rebound of coal power generation.
asserted
increase → exceed → generation
The next-largest increase was recorded in Turkey, which is hosting the UN climate summit in Antalya from Nov 9 to 20.
asserted
which → record → 20
US President Donald Trump has called climate change a hoax and rolled back clean energy policies while boosting fossil fuel production.
asserted
Trump → call → production
UNEP executive secretary Inger Andersen said she would not put the blame “squarely on one nation”, saying every country, especially those in the G-20, has “a specific duty to find a way to phase down their carbon emissions”.
asserted
country → say → emissions
To limit the overshoot beyond 1.5 deg C, Andersen said the world has an “urgent to-do item”: adding another 5,000 gigawatts of renewable energy over the next five years.
asserted
world → limit → years
The report details a scenario with a 50% chance of bringing global warming back down to 1.5 deg C by 2100.
asserted
report → detail → 2100
To get there, warming must peak around 1.8 deg C by 2050, and vast amounts of carbon dioxide would have to be removed from the atmosphere to bring temperatures down further.
asserted
amounts → get → temperatures
But this scenario assumes immediate emissions cuts of 6% per year, every year, until 2035, nowhere near current projections.
asserted
scenario → assume → projections
Some climate-vulnerable developing nations have accused bigger emitters of abandoning the Paris goals, and a showdown over the 1.5 deg C target is expected at COP31.
asserted
showdown → develop → COP31
“This is a historic failure of political leadership,” said Mohamed Adow, director of Kenya-based think tank Power Shift Africa.
asserted
Adow → say → Africa
“The science has been clear for decades, but governments have chosen delay over action,” Adow said.
asserted
Adow → choose → action
“The consequences will be measured in lives lost, not just degrees of warming.”

consequences → measure → warming
