We are due to enter another ice age, quite possibly in our lifetime. It has already been warmer longer than 2 of the past three warm periods. Quite possibly because of/thanks to AGW.
The oil has run out and now 2 miles of ice above new york is coming to a store near you.
Everything else is a distraction and propaganda.
But either way the Penguins will be fine.
So you’d rather believe that an ice age will come in our lifetime based on pretty much no evidence, but not that a declining penguin and seal population is beyond comprehension when you have numbers?
Great.
