Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) have developed a durable plastic that won’t contribute to microplastic pollution in our oceans.
Quantification of record-breaking subsidence in California's San Joaquin Valley (nature.com)
In California’s San Joaquin Valley, groundwater overdraft has caused dramatic and continued land subsidence during two main periods, 1925–1970 (“the historic period”) and post-2006.
China's emissions have now caused more global warming than EU – Carbon Brief (carbonbrief.org)
China’s historical emissions within its borders have now caused more global warming than the 27 member states of the EU combined, according to new Carbon Brief analysis.
Meltwater from Greenland and the Arctic is weakening ocean circulation (theconversation.com)
A vast network of ocean currents nicknamed the “great global ocean conveyor belt” is slowing down. That’s a problem because this vital system redistributes heat around the world, influencing both temperatures and rainfall.
Light-based photocatalytic system can break down PFAS at room temperature (phys.org)
Researchers at Colorado State University have found a new approach for breaking down PFAS—a group of human-made "forever" chemicals commonly used for their water-resistant properties that can carry health risks from long-term exposure.

How gophers brought Mount St. Helens back to life in one day (phys.org)
When Mount St. Helens erupted in 1980, lava incinerated anything living for miles around. As an experiment, scientists later dropped gophers onto parts of the scorched mountain for only 24 hours. The benefits from that single day were undeniable—and still visible 40 years later.
We discovered that the ocean's surface absorbs much more CO₂ than thought (theconversation.com)
The oceans play a pivotal role in drawing down atmospheric carbon dioxide (CO₂) and have so far acted as a brake on the full impact of climate change.
