The consequences of this more rapid and rapid warming are numerous: ice melt, permafrost, reduction, spatial and temporal, snow cover … All these elements profoundly modify ecosystems, and above all, “snowball” sphere of influence.
Less snow and less snow means less white surface covering the earth, which affects the albedo of these regions. The clearer a surface, the more it will reflect the sun’s rays: We heat up more when we wear a black T-shirt in direct sunlight than a white T-shirt. For Earth, it’s the same: the deeper its surface, the more it will store heat at ground level.
Hence this snowball effect: the hotter it is, the less snow there will be, and the more temperatures will continue to rise. Simultaneously the fires destroying forests, which also form a protective blanket against the heat, and we are heading towards an acceleration of warming in the Arctic region.
Another positive feedback loop (the scientific name for the snowball effect) is the thawing of permafrost, which releases CO2 that has been trapped in the atmosphere for hundreds of years.
Ultimately, the scientific community expects profound upheaval for the fauna and flora and the inhabitants of these regions.
