A just-published study coins a new metric: the "mortality cost of carbon." That is, how many future lives will be lost--or saved--depending on whether we increase or decrease our current carbon emissions. If the numbers hold up, they are quite high.

Global wet regions will not only receive more rainfall, but also experience temporally more varied rainfall events under global warming, according to researchers from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) and the UK Meteorological (Met) Office.

Twenty months after declaring a climate emergency and establishing a set of vital signs for the Earth, a coalition headed by two Oregon State University researchers says the updated vital signs "largely reflect the consequences of unrelenting business as usual."

Even in the absence of bark beetle outbreaks and wildfire, trees in Colorado subalpine forests are dying at increasing rates from warmer and drier summer conditions, found recent University of Colorado Boulder research.

About six gigatons -- roughly 12 times the mass of all living humans -- of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite (TanSat).

The National Science Foundation recently provided funding to over 100 herbaria across the Southeast U.S. to digitize more than three million plant specimens collected by botanists and naturalists across the country. Researchers tracked the speed and productivity of staff and students who handled the specimens, from the collection drawers to online repositories, to provide institutions with a framework to better determine the time and money needed to digitize remaining collections.
