Global temperatures approach 1.5°C warming limit

The United Nations has warned that the planet is on the verge of surpassing the 1.5°C warming limit relative to pre-industrial levels. Current global temperatures are approximately 1.37°C above these levels, rising at a rate of about 0.26°C per decade.

Extreme weather events, including heatwaves, droughts, intense rainfall, and wildfires, are already causing significant human and economic losses. In Europe, extreme heat has led to thousands of deaths and disrupted agriculture, river navigation, and energy production.

A report from the United Nations Environment Programme (UNEP) titled ‘Limiting Overshoot’ suggests that while temperatures might eventually fall, the world is now expected to exceed the 1.5°C threshold. This poses an existential threat to small island states in the Caribbean, Pacific, and Indian Ocean. These regions face saltwater intrusion into freshwater sources, loss of coral reefs, and increased coastal flooding long before any potential sea-level rise submerges them.

Experts emphasize that urgent action is required to reduce fossil fuel combustion and halt deforestation to alter the current climate trajectory.
