Not just a recent development….
It’s been around for at least the last 90 years:


And yet, we are still here and so far the arctic is not yet ice free.
Seems that climate panic was around 3 generations ago.
Of course, current climate data quoted today only starts at 1979….everyone ignores the intervening colder years (Global Coldering?) between 1939-40 and 1979 because it destroys their case and doesn’t make their claim that the earth is warming at an alarming rate….it ignores the colder period….when sea ice and glaciers mostly recovered.
Back in 1939, no one cared, and they didn’t have Soros and his Minions paying for the media propaganda and just plain lying to the public….
