The main reason for this is that warming enhances the amount of water vapor in the atmosphere, which then snows - off in the dry and
cold polar region where it releases energy and warms the atmosphere.
The temperature gradient creates atmospheric circulation, which transports heat from areas of equatorial excess to
the cold polar regions.
Warmer waters then warm the air, which reduces the temperature difference between
the cold polar region and the warmer rest of the Northern hemisphere.
And that warmth is welcome in
the cold polar regions where that poppy grows.
Cold polar regions are a natural result of inadequate solar radiation.
Climate change is altering the temperature gradient between the warm equator and
the colder polar regions; this is expected to affect the position and strength of mid-latitude storms.
As an exceptionally adaptable species, humans are found in all corners of the planet save
the coldest polar regions, highest mountain peaks, and lowest ocean troughs.
