A climate change-induced surge in brief but intense thunderstorms poses a growing but underrecognized threat to trees in tropical forests, a finding that could have major implications for carbon storage and tropical biodiversity under future global warming scenarios. That’s according to a recently published paper, which determines that short-lived but…

It’s an important question because the bees are critical to the fruit, vegetables, nuts and other foods that…

Even as the planet warms, parts of the United States can still be hit with brutally cold winter weather—and scientists now have a clearer idea of why. A team of researchers has identified two distinct patterns within the polar vortex, a swirling mass of frigid air located high in the…
