"It's that time of the year again: Shark Week. The TV program is so long-running that if you're under 37, you've never known a life without it. In honor of this oft misunderstood critter, we revisit our conversation with shark scientist Melissa Christina Marquez. She explains just how important sharks are to keeping the oceans healthy, including their role in mitigating climate change. Plus, there may be some talk about shark poop."

"As Hurricane Beryl batters Texas and extreme heat blankets much of the U.S. South and West, the world is set for another week of wild weather that human-caused climate change makes more likely."

"Cities across the West rely on fragile water sources — and aging infrastructure."

"Scientists hope a sediment-laying strategy can help preserve the marine highway while restoring marshlands."

"Allegations of possible payments to help secure votes. Claims of abuse of agency funds by top diplomats. A possible job offer to entice a candidate to withdraw from a race.

"Especially in the Midwest, climate change presents a growing threat to the nation’s nearly 92,000 dams, many more than 100 years old, as heavy rainfall, flooding and other forms of extreme weather become more common and severe."

"The world’s biggest banks and investors are continuing to funnel billions of dollars to carbon-intensive industrial livestock companies, undermining their own pledges to cut greenhouse gas emissions and fueling an ongoing boom in meat and milk production that threatens global climate goals."
