Pink Snow and the Climate, Extreme Weather and the Jet Stream, Saving Bats From Deadly Cold and more

Pink snow, also known as “watermelon snow” or “glacier blood,” is the result of a late summer bloom of pink colored algae that flourish in melting snow. And although snow algae are still very understudied, scientists are worried that darker snow will absorb more of the sun’s heat than white snow and cause the snowpack to melt more quickly, amplifying climate change. Also, weather records are routinely being shattered across the United States, with recent severe rainstorms in California, freezing temperatures in Texas, and a warm January thaw for the northeast. A climate scientist explains why a climate change-disrupted jet stream is behind much of this extreme weather. And in Texas, the wild weather delivered an unusual cold snap that some wildlife just couldn’t deal with. So local wildlife rehabilitators sprang into action to save around 1600 tiny Mexican free-tailed bats from hypothermic shock.
