Tens of millions of people living in the Southwest are dealing with what the National Weather Service says it's one of the longest heat waves in modern record. That extreme heat is even more dangerous than some might realize. Geoff Bennett discussed that with Jeff Goodell, a climate journalist and author of "The Heat Will Kill You First: Life and Death on a Scorched Planet."

It's estimated there are fewer than 350 North Atlantic right whales remaining. They are dying faster than they can produce and it's largely due to human causes. With so few left, experts are closely monitoring for new offspring and working to keep the whale from extinction. Science Correspondent Miles O'Brien reports.

Albert Einstein theorized that as heavy objects move through space and time, they create ripple effects in the fabric of our universe. Now an international team of scientists have detected new evidence of that. Researchers found new signs of gravitational waves that are affected by huge movements such as the collision of black holes. Science correspondent Miles O'Brien breaks it down.

Geoff Bennett discussed the search effort with Kristin Romey of National Geographic. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders

The ocean is rapidly heating up, hitting record-breaking levels. The National Oceanic and Atmospheric Administration reported that ocean surface temperatures spiked in April and May to the highest levels recorded since the 1950s. All this could have dangerous consequences for aquatic life, hurricane activity and global weather patterns. Amna Nawaz discussed what's happening with Kevin Trenberth.

A small group of orcas is causing a lot of damage to boats off the Iberian Peninsula. Last month, killer whales rammed a boat continuously for over an hour, managing to remove the rudder. In another incident, three orcas repeatedly struck a yacht causing it to sink. Stephanie Sy reports. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
