Heat warnings issued in the East and Midwest of the US

On Monday, tens of millions of Americans were forced to endure record heat in the Northeast and Midwest of the United States. This caused electricity supply disruptions and train travel.

In many parts of the United States, heat warnings began on the weekend and will continue into the coming week. East Coast officials warned of conditions "feeling" like 110 degrees Fahrenheit in many places as heat and humidity combine.

National Weather Service warns that the nighttime temperatures will not provide much relief from the "oppressive" heat, with temperatures forecast to be in the 70s or even 80s at night for East Coast cities.

Amtrak announced in a press release that the cars of its East Coast trains would be operating at lower speeds because of heat restrictions.

Amtrak heat restriction kicks in when temperatures exceed 95F (35C). Amtrak also reduces train speed when the track itself reaches 128F (54C).

Health experts advised employers to modify the working hours of outdoor workers, ensure that they have adequate breaks, hydration opportunities, and monitor for signs such as heatstroke or exhaustion.

The police departments of Raleigh, North Carolina and Washington D.C. are taking measures to protect officers stationed outside. They encourage them to drink water or stay in the shade if possible.

The U.S. electrical network operators told power plants to prepare to run at full force. They expected a spike in electricity demand as people use fans and air conditioners for cooling.

New York City's temperatures are expected to reach 97F (36C) on Tuesday, breaking the previous record set over a century earlier when the mercury reached 96F in June 1888.

Scientists warn that extremes like these are becoming the norm, and also challenge assumptions about regions that may be spared from the worst effects of climate change.

Many people ask, "Where is it safe?" Frumkin stated that the answer to this question is most likely - nowhere. "We didn't think that the upper Midwest would be susceptible to extreme heat."

Last week, Alaska's Arctic state registered its first heat advisory. China's temperatures soared last month.

Extreme heat is the most dangerous of all weather effects linked to climate changes. It's more deadly than hurricanes and floods.

The world experienced its warmest year ever last year. Temperatures are expected to rise for several decades, as emissions that cause climate warming continue to increase.
