Global ocean level rise tracked by new Jason 3 satellite just launched
Vandenberg Air Force Base, Calif. — Jason 3, a satellite launched to study the levels in global oceans, blasted off from here Sunday.
The mission was sponsored by the National Oceanic and Atmospheric Administration (NOAA) in partnership with NASA, the French space agency CNES, and the European Organization for the Exploitation of Metrological Satellites.
Since the satellite program was started in 1992, ocean level rises have been tracked to an average of 12 inches a year.
Because it is a measure of ocean warming and loss of land ice, the ocean level rise is considered an important indicator of human caused climate change.
“As human caused global warming drives sea levels higher and higher, we are literally re-shaping the surface of our planet, said Josh Williams, project scientist for Jason 3 at the jet propulsion lab at Pasadena. “These missions tell us how much and how fast,” he said.
High smog levels in Nevada and northern California not all locally caused
Western U.S.: Northern California, Nevada — A study of ozone not locally occurring in these two areas has shown that these background ozone levels push the figures up beyond levels allowed by the EPA due to ozone drifting in from Asia and that caused by forest fires that are increasing in intensity due to climate change, according to NASA.
Ozone production from cars and factories, which is smog on the surface level that is locally produced, is leveling out too high in these two states to meet stricter EPA standards.
This new study, which uses data gathered from satellites, might give these two areas data to request an exemption from the new standards which are expected to be 65 to 70 parts per billion down from 75 ppb.
NASA has suggested.EPA could announce its ruling Oct. 1.
