World on Track for 2.6°C as UN Warns 1.5°C Limit Is Now Unavoidable

A new United Nations report warns that the world will exceed the Paris Agreement's 1.5°C warming target, with current commitments putting the planet on a path to 2.6°C of warming this century.

The world will inevitably blow past the 1.5-degree Celsius warming limit set by the Paris Agreement within the next few years, according to a new United Nations report released ahead of the COP31 climate summit [267932]. Even in the best-case scenario, temperatures will overshoot to 1.8°C before countries can bring them back down [268951].

The report says the focus must now shift to limiting the duration of this "overshoot" period and eventually bringing global average temperatures back down [267932]. To achieve this, countries must remove massive amounts of carbon dioxide (CO₂) from the atmosphere — technologies and methods that pull CO₂ out of the air and store it [268951]. The report presents this overshoot path as the most optimistic outcome still available [268951].

A separate report from the UN Environment Programme warns that current commitments put the world on a path to 2.6°C of warming this century — far above the 1.5°C target [267866]. The report highlights a stark gap between what countries promise and what they actually do to fight global warming, and underscores the difficult task facing political leaders at COP31, scheduled to take place next month in Turkey [267866].

The warnings come as climate change has already cut the ocean's capacity to absorb carbon by roughly six percent, according to a new UN report released ahead of COP31 [273123]. The ocean absorbs about 30 percent of human-caused CO₂ emissions and 90 percent of excess heat trapped by greenhouse gases [273123].

Aggressive cuts to emissions could still limit how high temperatures rise and reverse warming by the end of the century, the report says [268225].
