Facing Future– Dec 2, 2021
Polar ice sheets are critical to maintain ocean currents, temperature, and salinity. Only if they stay frozen can we prevent sea level rise, intense storms, and disruption of the Jet Stream and major ocean currents. #PeterWadhams, pre-eminent polar scientist, explains how brightening marine clouds with tiny particles from sea water to reflect the sun’s heat could keep the arctic frozen. #PaulBeckwith, physicist, talks about both poles, permafrost, as well as the importance of #phytoplankton.
