World Already Can’t Prevent Key Warming Climate Target, UN Report Claims

A United Nations climate report says the world will exceed the Paris Climate Agreement's 1.5-degree Celsius warming target within a few years.

"The chance of holding global warming to below 1.5°C above pre-industrial levels with no or limited overshoot is gone," the report states. "Every additional fraction of a degree and additional year of warming above 1.5°C will increase climate impacts and risks, such as the deadly floods, heatwaves and wildfires that have plagued many nations this year."

Much of the report, Emissions Gap Report 2026: The point of return, lays out a roadmap to continue reducing emissions and to return average global temperatures to 1.5 degrees Celsius above pre-industrial levels by 2100.

The world is currently nearing the 1.5-degree threshold and is projected to warm to about 2.6 degrees Celsius by 2100 when compared to pre-industrial levels. The report states that drastic further reductions in carbon emissions could keep temperatures from rising much higher, limiting the rise to 1.7-1.8.

"To get on this pathway, stringent greenhouse emission reductions would have to start this year to deliver cuts of 18 percent by 2030, 45 percent by 2035 and 69 percent by 2040, all relative to 2025 levels," reads another passage of the report.

This is the first UN emissions gap report in 17 years to state that the world would definitely surpass the 1.5-degree Celsius threshold.

"The opportunity to limit warming to 1.5°C without overshoot has been lost, but the future remains crucially dependent on decisions taken today. Countries can still limit peak warming, shorten the duration of overshoot and keep the goals of the Paris Agreement within reach," the report states.

Although the report paints a bleak picture, the number of global deaths from extreme weather events and natural disasters has not been increasing. In fact, the numbers have been falling, largely thanks to warning systems and technological advancements.

"Over the last century, death rates have fallen by more than 90 percent," according to Our World In Data. "Even the total number of deaths has fallen substantially, despite there being four times as many people in the world as 100 years ago."

However, a yearly analysis of the cost and severity of natural disasters by NOAA's National Centers for Environmental Information (NCEI), found disasters that cost at least $1 billion in damage of been rising.

The analysis found that the costliest years for disasters in the U.S. since 1980 were 2017 ($395.5 billion), 2005 ($268.5 billion), 2022 ($183.6 billion), and 2024 ($182.7 billion). The last year included in the study was 2024.
