The long-term forecast looks bleak. The extreme heat could continue into August in some of the hardest-hit areas and even a brief glimmer of cooler hope for some parts of the country headed into the weekend will only mean new areas swelter as a heat dome slides west.

Heat preparedness has generally improved over the years. Chicago, for example, has expanded its emergency text and email notification system and identified its most vulnerable residents for outreach.

Earth’s average temperature set a new unofficial record high Thursday, the third such milestone in a week that prominent scientist says could be the hottest in 120,000 years. But it’s also a record with some legitimate scientific questions and caveats.

Cities across the U.S. from Medford, Oregon to Tampa, Florida have been hovering at all-time highs, said Zack Taylor, a meteorologist with the National Weather Service. Beijing reported nine straight days last week when the temperature exceeded 95 F.

While Canadian officials asked other countries for help fighting more than 400 blazes nationwide that already have displaced 20,000 people, air quality with what the U.S. rates as hazardous levels of pollution extended into central New York.

For the U.S. to transition to clean energy, it will take technologies beyond wind and solar to fuel airplanes, generate electricity and power industry. And the Biden administration is increasingly looking towards hydrogen to meet the demand – a source of energy that burns without pollution and that can be derived from water.

Using a 13-foot pencil-shaped robot that swam under the grounding line where ice first juts over the sea, scientists saw a shimmery critical point in Thwaites’ chaotic breakup, “where it’s melting so quickly there, there’s just material streaming out of the glacier.”
