A favorite idiotic claim of warmists is that it is too cold to snow in Antarctica
Heavy snow occurs at frontal boundaries, where cold air collides with warmer humid air. The colder the air, the more snow is going to fall. That is why ski areas invariably report more snow at the (colder) top of the mountain than at the bottom.
The reason that it doesn`t snow much in the interior of Antarctica, is that humid air never makes it there. The oceans around Antarctica are frozen and air masses precipitate out almost all their moisture before they reach the interior. If a humid air mass ever did miraculously make it all the way to Vostok, they would get a lot of snow.
When they aren’t claiming that it is too cold to snow, they are busy claiming that Antarctica is melting.
