Photo: stopadani/Flickr, CC BY 2.0 While coral reefs throughout the Indo-Pacific region have been bleaching in response to rising sea temperatures, the reefs around Marovo Lagoon in the Solomon Islands have mostly kept their color. But in March 2021, that all changed: the lagoon’s once-healthy reefs turned ghostly white as the water temperature rose to new highs, much to the distress of conservationists. Coral bleaching – when rising temperatures push corals to expel their life-sustaining algae – has become a problem ...

Spotting coral bleaching from space First global satellite network is now scanning coral reefs in real-time. The Allen Coral Atlas Monitoring System, New Caledonia on April 26, 2021. A world-first space-based coral reef monitoring project has just got off the ground – literally. The Allen Coral Atlas project is now using high-resolution satellites to scan nearly a quarter of a million reefs across the globe – from space – to monitor coral-killing bleaching events in real-time. “The current prognosis for the world’s coral reefs is bleak,” says remote sensing expert Chris Roelfsema ...

Planned NASA satellites will measure the vertical motions that lead to towering storm clouds. SANTIAGO BORJA NASA’s new fleet of satellites will offer insights into the wild cards of climate change May. 5, 2021 , 11:15 AM NASA is about to announce its next generation of Earth-observing satellites. As soon as this month, it will lay out preliminary plans for a multibillion-dollar set of missions that will launch later this decade. This “Earth system observatory,” as NASA calls it, will offer insights into two long-standing wild cards of climate change—clouds and aerosols—whil...

Global warming's extreme rains threaten Hawaii's coral reefs Coral reefs make up much of Hawaii's nearshore ocean ecosystem and are critical to the state's economy Author: Apr 30, 2021 Caleb Jones Associated Press HONOLULU — As muddy rainwater surged from Hawaii's steep seaside mountains and inundated residential communities last month, the damage caused by flooding was obvious — houses were destroyed and businesses swamped, landslides covered highways and raging rivers and streams were clogged with debris.  But extreme rain events predicted to become more common with human-caused global...
