A new UN report warns global temperatures will breach the critical 1.5C limit amid rising US emissions.

A United Nations report reveals that global warming is set to exceed the critical 1.5C temperature threshold. Even the most optimistic projections now point to mid-century temperature rises of up to 1.8 degrees Celsius. The findings highlight how policy retreats in the United States have driven up domestic pollution and strained international climate efforts.

The projectionOptimistic scenarios point to mid-century temperature rises reaching between 1.7 and 1.8 degrees Celsius.
The culpritThe United States stands out as the sole major economy where planet-warming pollution surged over the past year.
The outlookHumanity is steadily losing ground in global efforts to curb temperature increases and mitigate climate impacts.
