Even the South Pole is warming, and quickly, scientists say (New York Times)

June 29, 2020

Surface air temperatures at the bottom of the world have risen three times faster than the global average since the 1990s. Sharon Stammerjohn (INSTAAR) and Ted Scambos (NSIDC) are quoted about their commentary in Nature Climate Change.

The South Pole feels Pacific heat

June 29, 2020

In a "news and views" piece in Nature Climate Change, INSTAAR Sharon Stammerjohn and CIRES researcher Ted Scambos spell out the evidence and consequences of rapid warming at the South Pole and call for action to “flatten the curve” of global carbon emissions.

Why a ‘feverish’ Arctic will affect everyone on the globe (PBS News Hour)

June 26, 2020

A historic heat wave is occurring in the Arctic, already the fastest-warming place on Earth due to the increasing accumulation of greenhouse gases. Dr. Merritt Turetsky has studied the Arctic for decades. She joins William Brangham on PBS NewsHour to discuss causes and consequences of the Arctic's rising temperatures.

A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.

INSTAAR statement on systemic racism

June 19, 2020

We recognize that Black Lives Matter and stand with the protesters demonstrating against injustice. We are also reckoning with the overdue realization that we are part of the same systems that led to that violence. We commit to doing our part to dismantle implicit, systemic racism in our own spaces and list specific actions we will take within INSTAAR.

Tracking fossil fuel emissions with carbon-14

June 1, 2020

Researchers from NOAA and the University of Colorado have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon scientists have relied on for decades to date archaeological sites. In a paper published in Proceedings of the National Academy of Sciences, they report the first-ever national scale estimate of fossil-fuel derived carbon dioxide (CO2) emissions obtained by observing CO2 and its naturally occurring radioisotope, carbon-14, from air samples collected by NOAA’s Global Greenhouse Gas Reference Network.
