Get familiar with the concept of a "record-high nighttime low" temperature.

What's happening: This weekend's heat wave threatens to smash records nationwide, a dangerous situation for humans and animals alike.

  • Humidity "levels will make it feel as hot or hotter than the Southwest in parts of the Central and Eastern states,"according to Accuweather.

Why it matters: It can become very dangerous when temperatures don't cool down at night, meteorologists tell the AP. Parts of the East Coast won’t drop below the mid- to upper-70s or even 80s at night.

The big picture: "Hot weather is nothing new, of course," the New York Times reports, "especially in July. But climate change is making heat waves like this one more common."

Between the lines: This could also take a toll on flood-ravaged farms.

  • The "floods of the spring that delayed U.S. planting have meant plants have shallower roots and this is exacerbating the impact of the heat," per Bloomberg.
  • "Normally, it would take four or five days of temperatures in the 90s to stress crops ... [when] the root systems are as shallow as they are this year it only takes a day or two."

The bottom line: This wouldn't be a bad weekend to check up on your neighbors and family, particularly the elderly.

Records have begun to tumble across Western Europe as a second blistering summer heat wave struck — and forecasters warn the worst is far from over.

Details: The historic heat wave has shattered hottest temperature records in Germany, Belgium, the Netherlands and France, as the extreme weather system spreads. The World Meteorological Organization (WMO) said the heat would exacerbate drought in some areas and "fuel the risk of wildfires."

July 2019 was confirmed as the hottest month ever recorded, slightly topping or equal to global temperatures in July 2016, according to the European Union's Copernicus Climate Change Service (C3S).

The big picture: Regions around the world have seen unrelenting, record-breaking temperatures this summer, causing dangerous conditions and deaths throughout. Studies have shown that the increase in the frequency of heat waves and the rise in global temperatures is symptomatic of human-caused climate change.

An "oppressive and dangerous" heat wave that's gripping much of the U.S. has left at least 3 people dead and caused the cancellation of several public events, NBC News reports.

Why it matters: The National Weather Service said the heat was affecting much of the Midwest to the eastern U.S. this weekend. 147 million people in the Central and Eastern U.S. were under a heat advisory or excessive heat warning. "Very warm overnight temperatures limit recovery from daytime heat," the NWS said.
