Irish-led research highlights global warming

An Irish-led international study of a key global temperature range has found increasing thermal stress on the environment and further proof of global warming over half a century.

The major study of global diurnal temperature range (DTR), the most complete standalone study of DTR in over a decade, found clear evidence to support the conclusion that most global land areas analysed have experienced significant warming of both maximum and minimum temperature extremes since 1950.

The study also found Europe has experienced a greater decrease in DTR — the measure of the gap between the highest and lowest daily temperature — than either North America or Australia which could make it more difficult to survive heatwaves.
