Environmentalists' wild predictions

Now that another Earth Day has come and gone, let's look at some environmentalist predictions that they would prefer we forget.

At the first Earth Day celebration, in 1969, environmentalist Nigel Calder warned, "The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind."

Now they're saying global warming is going to kill us all. Predicting the weather for this weekend is an iffy proposition. Predicting the weather for 2058 is much iffier.
