Well, you say that. But what's the alternative - do the same test on polar bears and seals?

Wait:  Trees grow in the Arctic?

Dead trees don't sequester carbon.

Not the High Arctic. Trees are stunted, some growing only two inches high in Greenland, for example. But the tree line has been moving North for decades, sequestering a lot of carbon and sucking up a lot of flood waters that turn tundra into lakes and bogs.

Canada alone has lost 10,000 lakes but has gained a lot of new lakes, bogs and ponds as permafrost is replaced by thick peat bogs, not yet burning.

The Boreal forest of Siberia and Canada is on the march. The fastest tree on Earth is not the Dahomian Walking Tree, it is the Black Spruce, which can replant itself by two hundred miles a century. A snail's pace in human terms, but Speedy Gonzalez in tree form.

Bonzai!

What you call pine, spruce and fir trees from the True North, short of the High Arctic, of course.

Bring me a shrubbery. From Greenland!

Between emissions, plastic pollution and ocean acidification, I wonder if this is it.

"The expansion of annually-resolved and absolutely dated tree ring width measurements..."

"...researchers used a process-based forward model of boreal tree growth, with and without surface irradiance forcing as a proxy for pollutants..."
