Climate, migration and conflict combine to produce ‘deadly’ severe tropical cyclones like Chido
Credit: Pixabay/CC0 Public Domain Cyclone Chido was a “strong tropical cyclone” equivalent to a Category 4 hurricane in the Atlantic Ocean. It made landfall on Mayotte, a small island northwest of Madagascar, on December 14, producing wind gusts close to 155 mph (250 kph). It then struck Mozambique in East Africa with the same ferocity. The storm bypassed north of…

Study finds that natural regeneration of tropical forests has immense potential to address environmental challenges
Joshua Slaughter (left) and Matthew Fagan discuss a map of Costa Rica’s forested areas. A global map of potential natural forest regrowth areas, developed in a nature study led by Brooke Williams and Hawthorne Beyer and based on the Global Forest Lands Database developed by Fagan, covers the area of ​​tropical Mexico. This suggests that larger areas may be able…
