Two Crises

While the world watches the unfolding Iran crisis--and monitors tweets in what may become the first social networking political revolution--a combined report by 13 U.S. government agencies warns of the slowly unfolding Climate Crisis, which is likely to be even more consequential, but lacks the visible drama that media connects to the cause, which is global heating.

According to the New York Times story: " Even if the nation takes significant steps to slow emissions of heat-trapping gases, the impact of global warming is expected to become more severe in coming years, the report says, affecting farms and forests, coastlines and floodplains, water and energy supplies, transportation and human health."

Dealing with the inevitable effects of climate change is going to cost money and demand attention in increasing quantities. This is the other Climate Crisis that no one is talking about. Among the many conceptual challenges posed by the Climate Crisis is the time lag between cause and effect. The effects we are feeling--even if we don't acknowledge the causes--and the effects we will feel increasingly in the coming decade, according to this report and many other indicators, were caused by greenhouse gases emitted in the past.

But the truly devastating changes that are likely in the farther future are being caused by today's emissions, and tomorrow's. So we have to deal with two crises at the same time, one of which is invisible, and the other at the moment is not widely understood as consequences of greenhouse gas pollution. Our challenge will be--our challenge now is--to deal with both causes and effects simultaneously. It's probably the greatest challenge humanity will face for the forseeable future.
