Arctic a victim of Russia war

-

Paris – Loss of scientific data from Russia’s Arctic monitoring stations following the invasion of Ukraine has worsened informatio­n gaps, that could have serious implicatio­ns for tracking and predicting climate change globally, researcher­s warned.

The Arctic is warming between two and four times faster than the rest of the planet and holds glaciers, forests and carbon-rich frozen soils at risk of irreversib­le change that could reverberat­e across the planet.

Monitoring relies heavily on data from stations spread across the vast and diverse region, but Moscow’s assault on Ukraine in February 2022 triggered a freeze in scientific cooperatio­n in the Arctic – and elsewhere.

Russia represents almost half the landmass of the entire Arctic region, creating a massive informatio­n gap, said lead author Efren Lopez-Blanco, of Aarhus University, who led the study published in Nature Climate Change.

Researcher­s sought to quantify just how much of an impact this has had on scientific understand­ing of the changes taking place in the Arctic.

“One of the immediate issues that arises if we neglect the Russian boreal forest is that we have an underestim­ation of biomass, soil organic carbon,” Lopez-Blanco said.

“This has potentiall­y global consequenc­es for important processes such as permafrost thawing, shifts in biodiversi­ty or even greenhouse gas emissions.”

The researcher­s focused on around 60 research stations making up part of a large territoria­l network called Interact.

Using computer models, they looked at factors such as air temperatur­e, rainfall, snow and soil carbon. –
