Fires ravage Portugal as another blistering heat wave scorches Europe

• "Some models have been producing maximum temperatures in excess of 40C in parts of the U.K. over the coming weekend and beyond," per a U.K. Met Office statement — which noted the current record of 38.7C (102°F) was set at England's Cambridge Botanic Garden in 2019.

Meanwhile, the European Commission said in a statement Monday it had mobilized its firefighting fleet to help tackle "destructive forest fires" in Portugal, where a state of emergency has been declared and many residents have been forced to evacuate.

Driving the news: Studies show that as the climate warms, the frequency of heat waves dramatically increases — as does the severity and longevity of such events, per Axios' Andrew Freedman.

• "Extreme heat events do occur within natural climate variation due to changes in global weather patterns," the Met Office noted in its statement.
• "However, the increase in the frequency, duration, and intensity of these events over recent decades is clearly linked to the observed warming of the planet and can be attributed to human activity."
