HILL CITY/CHICAGO/NEW-YORK/JULY 1 - On Wednesday, record-breaking temperatures moved eastward from the Midwest, placing tens of millions under heat warnings that are expected to last through the holiday weekend on July 4, when Americans celebrate the 250th anniversary of the United States. Extreme heat is expected to raise "real-feeling" temperatures from 100 to 115 degrees Fahrenheit (37.8-46.1 degrees Celsius) in much of the region. This will increase the risk of heat related illness among vulnerable populations and threaten to overwhelm power grids that are already stressed by data centers and electric cars. Sabrina Hooper, a mail carrier in Hill City, Kansas (a high plains town located 270 miles east from Denver), was battling the heat just one week into her new job. Hooper, 34 said that the heat was debilitating to her job, which involves walking up to ten miles each day in order to deliver parcels. She says she finds relief in lawn sprinklers. "It's really nice." You can remove your hat, get it soaked, and then put it back on. Hill City, the nation's hot spot, was at 108 degrees for five days straight in 2012. Another record-breaking heatwave hit the region and pushed the heat index to 108. Heat index is a measure of how you feel when you add humidity to the temperature. Michelle Klein, 57 years old, a high-school science teacher in Chicago, began preparing over the weekend for the heat. She filled up her car, did her weekly shopping early, and stocked her refrigerator with cold drinks. She also gave her plants an extra soak. Klein, who went for her evening walk on Tuesday despite a heat index of 103 degrees, said that the basil needed more water.

Amy Kaspar, a property investor in the suburbs of the city, received an urgent call from a tenant who's air conditioner only blew out warm air. Kaspar found that the air conditioner was in perfect working order, but it could not cool the unit due to the heat and humidity.

Kaspar, a 50-year-old man, said, "With the wind it feels like you're standing right behind a bus exhaust in Chicago." Scientists said that the scorching temperatures in the U.S. were similar to those of western Europe which was recently engulfed by its own record-breaking Heatwave. This event would have been "virtually unachievable" without climate change caused by humans. Through years of research, scientists have proven that greenhouse gas emission makes heatwaves more intense and likely around the globe. New York City only experienced extreme heat on Wednesday morning. By then, the city had already opened hundreds of cooling centres and sent out more than a dozen 'cool vans' equipped with water electrolytes sunscreen and meals to help New Yorkers who were in need of relief.

On Wednesday, the air conditioning was turned up to the max at a Harlem senior center. A sign in thirteen languages advertised the facility as a "cooling?center" open to the public. Richard Allman, the director of the senior center, announced that it would be open past its normal hours during the July 4 weekend.

He said, "We make sure that this is a place where people can feel comfortable on a hot day." Before the heatwave hit, city officials asked sign operators in Times Square to lower the brightness of their signs to save energy. They also requested that businesses keep thermostats at a maximum of 78 degrees. Con Edison, the city's energy supplier, asked customers to reduce their energy consumption between 2 pm and 10 pm.

The city also increased the hours of public pools, opened additional cooling centres in libraries and municipal building, and expanded its street outreach efforts. Reporting by Brad Brooks from Hill City, Kansas and P.J. Huffstutter, Maria Tsvetkova, Joseph Ax and Julia Harte in New York.
