The United States is now at a record 15 different weather disasters that caused at least $1 billion in damage this year, the National Oceanic and Atmospheric Administration announced. It’s the most mega-disasters through the first seven months of the year since the agency tracked such things starting in 1980.

July is shaping up to be the warmest month on Earth in recorded history. But that heat isn’t just impacting the atmosphere — it’s having an impact on the ground beneath our feet.

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.

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.
