Valley fever is a dangerous threat to human health – and cases are on the rise in the arid southwestern United States, as wind from increasing dust storms can transport the fungal spores that cause the disease. Valley fever is caused by the Coccidioides fungus, which grows in dirt and fields and can cause fever, rash and coughing. Using NASA resear
In a decade filled by record-breaking events including raging wildfires, numerous hurricanes, unseasonal flooding and historically cold temperatures, NASA has continued to learn more about how the planet is changing and the effect it has on Earth’s systems.
Fertilizers used in farming contain high amounts of nutrients, such as phosphorous, to help crops grow. But these same nutrients can cause unwanted plant growth and potentially harm ecosystems miles away if agricultural runoff flows into nearby rivers, lakes, or coastal waters.
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.
