The August Complex Fire and others this fire season have been sending far-reaching plumes of wildfire smoke into the atmosphere that worsen air quality in California and beyond. Predicting where that smoke will travel and how bad the air will be downwind is a challenge, but Earth-observing satellites can help.
Scientists have been researching how Arctic glaciers responded to global warming as a result of significant temperature increases at the northern polar region?
A July 14, 2020 ASTER image of the St. Patrick Bay Icecaps, Hazen Plateau, Ellesmere Island, Canada, shows that the icecaps have disappeared. Mapping of the icecaps’ extent using aerial photos, GPS, and ASTER images, from 1959 to present, documents their shrinking and eventual vanishing.
Dr. Mark Sezerre (Director of NSIDC), said: “We’ve long known that as climate change takes hold, the effects would be especially pronounced in the Arctic. They’re the victims of human-caused warming that has occurred three times more rapidly in the Arctic than anywhere else.”Satellite data provide the most important method to monitor cryosphere changes on the Earth.
