Faced with a loss of crucial climate data, scientists are finding workarounds as relations with Russian partners break down.
across many fields of science, it is having a particularly profound impact on climate science in the Arctic. Russia makes up a huge portion of the region, which is home to melting sea ice, thawing permafrost and massive wildfires — all of which must be monitored to understand and fight climate change.
To some, the breakdown in relations is worse than it was during the height of the cold war. “It’s significantly worse now because of the open warfare” in Ukraine, says Terry Callaghan, an ecologist at the University of Sheffield, UK, who has worked in the Arctic for more than five decades. “It’s terribly depressing.
Some US scientists have been interpreting this message as leaving the door slightly open for current projects. At the University of Alaska, for example, Kelly heads an NSF-funded project called the Study of Environmental Arctic Change. One of the project’s partners is the North-Eastern Federal University branch in Chukotka, in Russia’s Far East.
In the meantime, scientists outside Russia can gather some of the relevant information they need through remote sensing. But tools are limited: few satellites can reliably track methane emissions in the Arctic, and a French–German mission known as MERLIN, which will improve satellite tracking of Arctic methane, isn’t slated to launch until 2027 at the earliest.Some collaborations with scientists in Russia continue on a personal basis.
