Do heat waves happen in rivers? How do river heat waves (RHW) compare to air heat waves (AHW)?
www.pnas.org/doi/10.1073/...
Here we show: 1) RHWs occur less frequently & intensively but last twice as long as AHWs; 2) RHW have risen much faster than AHWs.
Congrats to Dr. Kayal Sadayappan!

Do forest recovery + higher soil organic C elevate production of dissolved inorganic C? No, because cooling soils + lower moisture reduce soil respiration.
On the other hand, drier climate does diminish carbonate weathering + reduce DIC export

As wildfires rage through the LA area, air pollution is a major concern. It is important to recognize that such disasters also severely impact river water quality through land-river connectivity, particularly following post-fire rainfall.
