- Fifty years from now, floods in the eastern half of the United States will last longer as climate change creates warmer and wetter weather patterns, a new study suggests.
- Floods will last longest in the winter, the analysis predicts, marking a shift in damaging flood seasons.
- The trends underscore a need to renovate levees and dams, flood channels, and other infrastructure to protect residents and cities, researchers say. 

- Ecologists are unclear why moose populations in Ontario, Canada, have declined by 20 percent in the last two decades.
- University researchers and Indigenous community biologists combined peer-reviewed field studies and extensive interviews with First Nations tribal members to explore the possible reasons.
- Both sets of data pointed to climate change as the key factor, but stories and observations from tribal members offered many other potential causes overlooked by Western science.

- Carbon mineralization is a process by which gaseous carbon dioxide reacts chemically with certain rock types and transforms into solid carbonate minerals. This natural process is an essential part of the long carbon cycle, which has helped regulate Earth’s temperature for millions of years.
- Mimicking this natural process, subsurface mineralization is a human-induced carbon storage technology, with CO₂ injected directly into in-situ basalt, peridotite and other rock types to accelerate mineralization. In 2012, Iceland’s CarbFix project first demonstrated subsurface mineralization and has stored more than 100,000 metric tons of CO₂ since then.
- Proponents say the technology is safe, verifiable and offers rapid permanent CO₂ storage, giving this sequestration method advantages over other options such as reforestation (where forests can be cut or burn) or conventional geologic storage in sedimentary basins (which requires long-term monitoring for leaks).
- Interest in subsurface carbon mineralization is growing: expanding in Iceland, with test projects in the U.S. and Oman, and others recently announced. But investment in field pilots is needed, plus regulatory and policy support, for scale-up. Unlike other geoengineering methods, this technique seems to pose few environmental problems.
