LONDON (AP) -- Britain's record-breaking heatwave is spurring calls for the government to speed up efforts to adapt to a changing climate after wildfires created the busiest day for London firefighters since bombs rained down on the city during World War II.

The country got a break Wednesday from the dry, hot weather that is gripping much of Europe as cooler air moved in from the west.

The country hit a record high of 40.3 degrees Celsius (104.4 Fahrenheit) Tuesday at Coningsby in eastern England.

Even so, travel was disrupted for a third day as rail operators repaired damage caused by the heat, and firefighters mopped up hotspots at the scene of Tuesday's fires.
