Study finds decline in the stability of water yield in watersheds
Extreme climatic events such as droughts, heat waves, and cold spells not only modify hydro-meteorological conditions but also alter the underlying characteristics (e.g., wildfires due to droughts changing the vegetation cover). Intense human activit.....»»
Artificial reef designed by engineers could protect marine life, reduce storm damage
The beautiful, gnarled, nooked-and-crannied reefs that surround tropical islands serve as a marine refuge and natural buffer against stormy seas. But as the effects of climate change bleach and break down coral reefs around the world, and extreme wea.....»»
Seagrass meadows face uncertain future, scientists say
James Cook University scientists who analyzed seagrass meadows around the world say the crucial habitats are under increasing threat and need to incorporate new management strategies if they are to survive climate change. The study is published in Gl.....»»
Using nature to help the climate: Four ways that work
A new study finds that four nature-based climate solutions—the ones that companies and other entities use most often to claim carbon credits—have robust scientific foundations. The four pathways are conservation or reforestation of tropical fores.....»»
Antarctic sea ice near historic lows: Arctic ice continues decline
Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the.....»»
