Is this what they mean by Black Friday?

From the story, more on those ‘tipping points”:

“In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock-on effects on ocean ecosystems around the globe.”

    It’s sobering, but equally-sobering is wondering how many out there in the black-Friday spending spree would ponder what’s happening to our planet….. 200 species extinct yesterday; 200 today; 200 tomorrow…
