wrong, the sun has cycles (called sunspots) when more radiation (heat) is dispersed into the solar system. So the sun does affect the climate of mother earth.
The earth also wobbles a degree or two on its axis which affects climate, then there are the changes in ocean currents which affect the climate in parts of earth and not others, which may answer your greeland/NA question.
The fraud is the climate religion and their ideas that the acts of humans can cause, reverse, or change the climate of our planet. We can and do pollute it, but we, short of all our nuclear war, cannot change it. And even in the event of nuclear war, the changes would be temporary in the life of the planet.
