The recently released National Climate Assessment discussed the impacts of climate change on our nation’s water supply and agricultural productivity. The levels of uncertainty regarding the future of our water supply are troubling. Changes in precipitation patterns will intensify droughts and increase heavy downpours. Hotter, more extreme weather will disrupt how well and how … [more…]

An international collaboration among dozens of scientists has come within less than a millimeter of attaining a long-sought goal: accounting for all the jostling, overlapping, and constantly changing contributions to global sea-level rise.

A just-published paper assembles virtually all the puzzle … [more…]

Maryland’s Dorchester County is ground zero for climate change on Chesapeake Bay, as rising seas claim more and more land. An e360 video explores the quiet beauty of this liquid landscape and how high tides and erosion are putting the bay’s rural communities at risk.

I’m making a film … [more…]

The Seafloor Is Dissolving Because of Climate Change

Carbon emissions are acidifying the ocean so quickly that the seafloor is disintegrating.

According to a new study, ocean acidification is setting off a dangerous feedback loop that’s dissolving the very bottom of the ocean.

According to a study published this week in PNAS, this sets off a feedback loop that acidifies the ocean even more quickly, a process that is already killing off foundational marine life species such as … [more…]
