The Montreal Protocol, the international treaty adopted initially to protect and ultimately to heal Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. But in a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has also significantly reduced climate-altering greenhouse gas emissions from the United States.
Ecologists need to understand what and where soil microbes live in Earth’s ecosystems—these microorganisms can influence what can thrive above. But there’s a gap in the field: Today’s climate conditions do not fully explain the types of microbes they see. So CIRES researchers at the University of Colorado Boulder are looking thousands of years back in time—and they’re finding answers.
Conditions thousands of years ago can leave a lasting mark on present-day soil microbes
