Glaciers melting at record rates is becoming not rare. Penguin and seal populations in Antartica and polar bear populations dwindling in the Artic because of the lack of ice are things becoming not rare. A 1-2 degree shift in the global mean temperature is becoming not rare. The polar caps shinking water fissures in Greenland and Iceland are things becoming not rare. Closed minded people who only see what they choose to see are things that are not rare. Try looking past your front/back window.
