Lack of data about conditions in the Russian Arctic is already hampering climate science, and will cause ever-growing gaps in our understanding of how climate change affects the fastest-warming region of the planet, scientists warn.
The Arctic is warming up to four times faster than the Earth as a whole. And Russia has more Arctic land than any other nation. But, since Russia invaded Ukraine, it's been increasingly difficult for climate scientists in Russia to collaborate or share data about conditions in the country's vast frozen areas.
