Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

The research, published in Nature Geoscience and led by the University of Bristol and National Oceanic and Atmospheric Administration (NOAA), puts the rise in part down to the chemicals, known as chlorofluorocarbons or CFCs, being used to make other ozone-friendly alternatives to CFCs. —Dr Western Resources Western, L.M., Vollmer, M.K.,

Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

These findings show that stratospheric water vapor represents an important driver of decadal global surface climate change. Over the last century, global average surface temperatures have warmed by about 0.75 °C (0.42 °C), with much of it occuring the last half. —Solomon et al.

Study Finds Unexpected Decadal Decline in Global Evapotranspiration, Links It to Moisture Limitation in Southern Hemisphere

Green Car Congress

The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, according to the first major study of evapotranspiration on a global basis. This is the first time we’ve ever been able to compile observations such as this for a global analysis.
