Extreme rainfall over land exacerbated by marine heatwaves - Nature Communications
This study shows that oceanic extreme warm events, termed marine heatwaves, exacerbate extreme rainfall over land by 20–30%, increasing flood risks for coastal regions.

There is still hope to save irreplaceable coral ecosystems, but time is running out. Baby corals can ride ocean currents for hundreds of miles, but they can’t outrun climate change. And humans have a limited capacity to make new reefs in cooler waters. buff.ly/nY4jJs0 #WorldOceanDay
theconversation.com
Coral reefs face an uncertain recovery from the 4th global mass bleaching event – can climate refuges help?
As baby corals float in the currents, they can expand their species’ range. But can they get to climate refuges fast enough to survive? A new study has good news and bad.
