None of us alive today will be around to verify this and certainly those fearmongering today won’t be alive to be held accountable when their daft doomsday predictions fail to materialize in 79 years.
Millions of children alive now will likely be alive in 2100 (a baby born in 2021 will be 78 on Jan. 1, 2100) but very few if any current Freepers will still be alive. Maybe there will be a thread on Free Republic in January 2100 mocking the people who predicted that Emperor penguins would be extinct by then, as countries try to cope with inundations of unwanted Emperor penguins displacing native species.
