Missing a field season can be devastating if your research subject is melting away. Karen Lloyd

From permafrost microbes to survivor songbirds – research projects are also victims of COVID-19 pandemic

Three scientists describe the fieldwork they've had to delay in 2020 because of the pandemic. These are setbacks not just for their careers, but for the body of scientific knowledge.
This Arctic heat wave has been unusually long-lived. The darkest reds on this map of the Arctic are areas that were more than 14 degrees Fahrenheit warmer in the spring of 2020 compared to the recent 15-year average. Joshua Stevens/NASA Earth Observatory

100 degrees in Siberia? 5 ways the extreme Arctic heat wave follows a disturbing pattern

The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.

Collapsing permafrost is transforming Arctic lakes, ponds and streams

Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
