Rome — Temperatures reached new highs on Monday as heat waves scorched parts of the Northern Hemisphere, triggering health warnings and fanning wildfires in the latest stark reminder of the effects of global warming. From North America to Europe and Asia, people gulped water and sought shelter from the sweltering heat, with the mercury expected to reach new highs in several places in the next few days.

    Europe, the globe's fastest-warming continent, was bracing for its hottest-ever temperature this week on Italy's islands of Sicily and Sardinia, where a high of 118 degrees Fahrenheit is predicted, according to the European Space Agency.

    "We're from Texas and it's really hot there, we thought we would escape the heat but it's even hotter here," Colman Peavy, 30, said as he sipped a cappuccino at an outside terrasse in central Rome with his wife Ana at the start of a two-week Italian vacation.

    With June already having been the world's hottest on record and the first week of July also setting a global record, according to the EU weather monitoring service, Mother Nature seemed intent on July not falling far behind. 

    Authorities started issuing warnings about significant health risks last week, primarily in Spain, where temperatures may soon reach a staggering 113 degrees in some regions.   

    In Cyprus, where temperatures are expected to remain above 104 degrees through Thursday, a 90-year-old man died as a result of heatstroke and three other seniors were hospitalized, health officials said. Italians were warned to prepare for "the most intense heat wave of the summer and also one of the most intense of all time," with the health ministry sounding a red alert for 16 cities including Rome, Bologna and Florence.

    Temperatures were due to climb as high as 110 degrees in Rome on Tuesday, smashing the record of 105 degrees set in August 2007. Nevertheless, visitors thronged to tourist hot spots like the Colosseum and the Vatican.

    "I'm from South Africa. We're used to this heat," said Jacob Vreunissen, 60, a civil engineer from Cape Town. "You have to drink lots of water, obviously, wear your hat, and that's about it."
