Climate change – Analysis and Comment

The South’s aging water infrastructure is getting pounded by climate change – fixing it is also a struggle

Extreme downpours and droughts, both fueled by rising global temperatures, are taking a toll on water infrastructure. Communities trying to manage the threats face three big challenges.

Using research to solve societal problems starts with building connections and making space for young people

Use-inspired research goes beyond translational research to build lasting connections between researchers and communities.

Coastal wetlands can’t keep pace with sea-level rise, and infrastructure is leaving them nowhere to go

A coastal scientist explains why marshes, mangroves and other wetlands can’t keep up with the effects of climate change, and how human infrastructure is making it harder for them to survive.

Climate engineering carries serious national security risks − countries facing extreme heat may try it anyway, and the world needs to be prepared

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?

Arctic rivers face big changes with a warming climate, permafrost thaw and an accelerating water cycle − the effects will have global consequences

A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.
