In a recent report the World Meteorological Organization highlights an alarming acceleration of climate change indicators, issuing a "red alert" due to unprecedented increases in greenhouse gases, temperatures, and ice melts.

Jamey Keaten and Seth Borenstein report for the Associated Press.

In short:

• Last year saw record-breaking increases in global temperatures and ice melts, pushing the world closer to exceeding the Paris Agreement's 1.5°C warming limit.
• Over 90% of the world's oceans experienced heatwave conditions in 2023, and renewable energy capacity saw significant growth, offering a glimmer of hope.
• The U.N. Secretary-General describes the current state as a planet on the brink, with climate chaos escalating due to fossil fuel pollution.

Key quote:

"Never have we been so close – albeit on a temporary basis at the moment – to the 1.5° C lower limit of the Paris agreement on climate change."

— Celeste Saulo, secretary-general of the World Meteorological Organization

Why this matters:

The WMO report—a "red alert to the world"—pleads for urgent action to curb global warming, touching directly on health outcomes through increased heatwaves, floods, and other extreme events. Heat, air pollution and climate change … oh my! Was summer 2023 the new normal?
