The new study helps illuminate how changes in forest composition followed European settlement and natural changes in climate.
The First Assessment of Toxic Heavy Metal Pollution in the Southern Hemisphere Over the Last 2,000 Years
An international team of scientists led by DRI found evidence of Southern Hemisphere heavy metal pollution preserved in Antarctic ice cores from early Andean cultures and Spanish Colonial mining that predates the Industrial Revolution by centuries.
3000 years of carbon monoxide records show positive impact of global intervention in the 1980s
An international team of scientists have assembled the first complete record of carbon monoxide concentrations in the southern hemisphere, based on measurements of air.
Volcanic Eruptions Triggered Historical Global Cooling
The new study, led by the School of Earth and Environmental Sciences at St Andrews with international colleagues from the Desert Research Institute and others in Switzerland and the USA, and published in The Proceedings of the National Academy of Sciences (PNAS) (6 November 2023), finds that massive volcanic eruptions caused historical global cooling.
Field Notes From DRI’s Ice Core Team in Greenland: A Story Map
A team of DRI scientists returned to Greenland in May 2023, where they are drilling a 150m long ice core to study interactions between ice chemistry and microbial life.
Field Notes From a DRI Research Team in Greenland: A Story Map
In May 2022, a team led by scientists from DRI in Reno, Nevada departed for Greenland, where they plan to collect a 440 meter-long ice core that will represent 4,000 years of Earth and human history.
Early Human Activities Impacted Earth’s Atmosphere More Than Previously Known
An international team of researchers led by Desert Research Institute analyzed ice core samples from Antarctica’s James Ross Island and found early human activity caused significant changes to the earth’s atmosphere. Their findings were just released in a new Nature journal article.
Study shows a recent reversal in the response of western Greenland’s ice caps to climate change
Although a warming climate is leading to rapid melting of the ice caps and glaciers along Greenland’s coastline, ice caps in this region sometimes grew during past periods of warming, according to new research published today in Nature Geoscience.
DRI Ice Core Lab Data Shows Magnitude of Historic Fire Activity in Southern Hemisphere
A new study in Science Advances features ice core data from the DRI Ice Core Laboratory and research by Nathan Chellman, Ph.D., Monica Arienzo, Ph.D., and Joe McConnell, Ph.D.
Eruption of Alaska’s Okmok volcano linked to mysterious period of extreme cold in ancient Rome
Reno, Nev. (June 22, 2020) – An international team of scientists and historians has found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of Alaska’s Okmok volcano, located on the opposite side of...
