Typhoon Haiyan and the increasing occurrence of other extreme weather phenomena in recent years are evidence of the impact human activity has on the climate [see IPCC report]. This underscores the dire need for collective global action to slow and even reverse climate change. Incidentally, delegates from around the world are meeting in Warsaw this week for COP19, the main UN climate change conference of 2013; the destructiveness of Haiyan underscores the importance of these talks.
But if past climate talks are any indicator of the progress we can expect out of Warsaw, then prepare to be underwhelmed. One problem with these talks is that nations tend to be unwilling to compromise their economic growth (or the business interests of their companies) for climate mitigation, even though climate change will put an immense strain on future economic activity and cost more to mitigate down the road. In other words, nations are willing to pursue short-term gains, even if it means jeoporizing the well-being of their future economy and the future world in general.
