“Siberia is heating up around twice as quickly as other parts of the world.

It is -64F in Siberia.
They are probably not lying if they are taking the measurements near the summer solstice. Near the winter solstice, it is probably cooling twice as fast as other places.
Thawing of Siberia apparently doesn’t increase the available arable land or increase the growing season, but it does release deadly viruses. I think I see the methodology here. Look up a doomsday scenario in an old science fiction book, and find a way it could be caused by AGW, and your funding is assured.
