Eyeing Climate Change, Satellites Provide Missing Information

[font size=4]Scientists develop a new method to measure the impact of pollution on global warming and reduce the gaps in knowledge on climate change[/font]

[font size=3]An international team of scientists led by Prof. Daniel Rosenfeld from The Hebrew University of Jerusalem found a way to measure missing critical information needed to quantify manmade responsibility for climate change.
In a paper published in the journal Proceedings of the National Academy of Sciences, the authors describe a new way to determine both cloud-base updraft speeds and quantify the aerosol particles’ ability to create cloud droplets. The new method used measurements from an existing meteorological satellite, operated since 2012, rather than conventional aircraft and ground stations.
"This new satellite methodology enables us to quantify climate effects on a global scope, provides a more accurate assessment of the processes affecting global warming, and reduces the uncertainty there is about climate change," said Prof. Rosenfeld, an expert on climate change from the Hebrew University's Institute of Earth Sciences.
…
Estimates of global warming expected by the end of the 21st century due to manmade emissions range between 1.5 to 4.5 degrees. This uncertainty is a major cause for the intense public debate on the responsibility of mankind for climate change and the actions needed to mitigate its impacts.
