Weather tracker: Heatwaves have arrived in the northern hemisphere

Temperatures are soaring from Canada to India and Saudi Arabia, with fatal consequences

Summer has arrived with full force across the northern hemisphere, bringing extreme heat to many countries. Northern parts of India have been experiencing a heatwave, and Delhi recorded a minimum night temperature of 35.2C, the warmest night the capital has recorded since June 2010, according to the Indian Meteorological Department.

A maximum temperature of 44.7C was recorded on Wednesday in Ganganagar, in the north-west of the country, close to the Pakistan border. The high temperatures have pushed power demands to record highs of 8,647MW for Delhi alone, with the total consumption for northern India rising to almost 90,000MW on Tuesday. A plane was also left stranded on the ground for more than an hour during the heatwave without any air conditioning.
