Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns — ScienceDaily

Researchers have assessed abrupt thaw studies across the permafrost zone to estimate the overall effect. They found carbon emissions have the potential to double the climate feedback associated with permafrost thawing because abrupt thaw releases more methane. It will also have drastic effects on landscape, from altering traditional travel and hunting patterns in the North, to causing costly infrastructure damage to roads and rail lines.

BBC on the “evolution” of robots (missing the “by design” part) | Uncommon Descent

BBC has done a mini-series on the “evolution” of robots, even speaking of invasive species. The silence on the “by design” part is conspicuous, especially as they use a biologist (male) and an engineer (female) as their key personalities:https://www.youtube.com/watch?v=hRuBZLe8vfsThe blind

Climate, grasses and teeth: The evolution of South America mammals — ScienceDaily

Atmospheric circulation changes about 6 million years ago dried the South American climate and fueled the expansion of grasslands and grass-eating mammals, according to new research.
