Vital indicators of climate change - Global temperature

Vital indicators of climate change - Global temperature


2024 was the warmest year on record, with the annual average global temperature about 1.55℃ above the pre-industrial (1850-1900) levels, marking the first year to exceed the 1.5℃ level. The last ten years (2015-2024) were the warmest ten years on record globally.

Although an individual year surpassing the 1.5℃ level does not mean that the long-term temperature goals of the Paris Agreement are not achievable, it indicates the urgent need for significant reduction in global carbon emissions to avoid the further worsening of climate change impacts.
