Humans will be extinct in 100 years because the planet will be uninhabitable, said the late Australian microbiologist Frank Fenner, one of the leaders in the effort to eradicate smallpox during the 1970s. He blamed overcrowding, denuded resources and climate change.
Fenner’s prediction, made in 2010, is not a sure bet, but he is correct that there is no way emissions reductions will be enough to save us from our trend toward doom. And there doesn’t seem to be any big global rush to reduce emissions, anyway. When the G7 called on Monday for all countries to reduce carbon emissions to zero in the next 85 years, the scientific reaction was unanimous: That’s far too late.
And no possible treaty that emerges from the current United Nations Framework Convention on Climate Change in Bonn, Germany, in preparation for November’s United Nations climate conference in Paris, will be sufficient. At this point, lowering emissions is just half the story — the easy half. The harder half will be an aggressive effort to find the technologies needed to reverse the climate apocalypse that has already begun.
For years now, we have heard that we are at a tipping point. Al Gore warned us in An Inconvenient Truth that immediate action was required if we were to prevent global warming. In 2007, Sir David King, former chief scientific advisor to the British government, declared, “Avoiding dangerous climate change is impossible – dangerous climate change is already here. The question is, can we avoid catastrophic climate change?” In the years since, emissions have risen, as have global temperatures. Only two conclusions can be drawn: Either these old warnings were alarmist, or we are already in far bigger trouble than the U.N. claims. Unfortunately, the latter seems to be the case.
