April 2026 Shatters Temperature Records Amidst Global Climate Extremes

RTÉ News reports on the latest climate data, revealing that April 2026 was marked by exceptionally high sea surface temperatures, ranking as the second warmest on record globally, excluding polar areas. This alarming trend is accompanied by widespread marine heatwaves, particularly in the tropical Pacific, signaling a continued and intensifying climate crisis.

The global average surface air temperature for April 2026 stood at 14.89°C, a significant 1.43°C above pre-industrial levels. This places the month as the joint third-warmest April globally since records began. The data, compiled by the EU Copernicus Climate Change Service, paints a stark picture of a planet grappling with unprecedented warming.

Furthermore, the report highlights a disturbing decline in Arctic sea ice, which reached its second-lowest extent for April. This, coupled with a series of extreme weather events worldwide—from devastating floods in the Middle East and Asia to severe droughts in southern Africa—underscores the escalating climate emergency. As Samantha Burgess of the European Centre for Medium-Range Weather Forecasts notes, these are clear hallmarks of a climate increasingly defined by extremes, demanding urgent attention and action.

Sea surface temperatures were near record levels with widespread marine heatwaves, Arctic sea ice remained well below average, and Europe saw sharp contrasts in temperature and rainfall; all hallmarks of a climate increasingly shaped by extremes.
