2023: ‘bonkers year’ for global climate
Records were once again broken last year for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, and retreat of glaciers, according to a new global report issued by the World Meteorological Organization (WMO). The WMO State of the Global Climate 2023 report finds that on an average day in 2023, nearly one third of the ocean surface was gripped by a marine heatwave, harming vital ecosystems and food systems—far beyond the already inflated levels seen in recent years. Antarctic sea ice reached its lowest extent on record—at one million square kilometers below the previous record year of 2022, an area equivalent to the size of France and Germany combined. One leading oceanographer wryly stated: “The scientific term is bonkers year.” (Photo: CounterVortex)
