A 1 C increase in temperature has set off a chain of events disrupting the entire ecology of the world’s largest High Arctic lake.
“Because it’s glacial meltwater, the amount of fine sediment going into the lake has dramatically increased as well.
That in turn affects how much light can get into the water column, which may affect biological productivity in the lake.”.
The changes resulted in algal blooms and detrimental changes to the Arctic char fish population, and point to a near certain future of summer ice-free conditions.
And this is in response to only a third of what the conservative scenarios are for future warming,” said St. Pierre.
So are these dramatic changes in the High Arctic’s largest lake a sign of things to come?
The study, “The World’s Largest High Arctic Lake Responds Rapidly to Climate Warming,” was published in the March 29 issue of Nature Communications. »
