Several record-breaking heatwaves worldwide last month point to more “extraordinary” temperature extremes to come, the European Union’s Earth Observation Programme has warned. Globally, last month was the 4th warmest June ever recorded. North America sweated through its hottest ever June, with parts of the US and Canada breaking previous temperature records by more than 5C. While scientists aren’t surprised that there are more heatwaves, they’re concerned about heat records being broken by wide margins. Climate change will see that continue, they say, regardless of any reductions in carbon emissions.
