New research shows that climate change has reduced what people are seeing as Earth’s reflection, according to an essay published in the journal Geophysical Research Letters.
Scientists at the Big Bear Solar Observatory in Southern California have been investigating the changes in Earth’s appearance since 1998, searching for changes on time scales ranging from daily to decadent.
Researchers have put together two sets of data to work out whether and how the brightness of the Earth changes.
(One square meter is slightly less than 11 square feet.) The biggest part of this variation would fall within the last three years of an earthquake data they analyzed up to 2017; the CERES data continues until 2019, with an even sharper drop in the long run.
In a new study, scientists combined this data with NASA observations of the Radiant energy system of clouds and the Earth. The CERES has been in operation through a series of NASA aircraft and satellites from the U.S. National Oceanic and Atmospheric Administration (NOAA) since 1997.
Specifically, the CERES data showed a loss of bright lowland clouds over the eastern Pacific off the west coast of America, where scientists record another sharp rise in sea surface temperatures.
