In 2024, global climate trends are cause for both deep alarm and cautious optimism. Last year was the hottest on record by a huge margin and this year it is likely to be hotter still. The annual global average temperature may for the first time exceed 1.5 degrees above pre-industrial levels — a threshold crucial for stabilising the earth’s climate.
Without immediate action, we are at grave risk of crossing irreversible tipping points in the earth’s climate system. Yet there are reasons for hope.
Global greenhouse gas emissions may peak this year and start falling.
