Learning from Sandy

Sandy is the power of Nature over man, man in all his technological might. But more important Sandy shows human failure: our failure to listen to those who understand far better than most of us do the impact of human behavior on the atmosphere, our climate system, and the ecosystems that surround us.
While it is true that no singular weather event can be directly linked to human-caused global warming, the Intergovernmental Panel on Climate Change has reported with increasing confidence that weather extremes will become more frequent, more widespread, and more intense with rising greenhouse gas emissions. The IPCC’s assessments have led to many prominent people term global warming as this century’s greatest threat.
Sandy reveals our refusal to take responsibility for our actions and our skepticism that real change (of natural systems as well as of our own behavior) is possible, as Worldwatch Institute. (Read the excerpts from the institute's note.)
The storm devastated the Caribbean before heading up the East Coast of the United States, then turned inland and finally crawled all the way up to Canada, reminding us that climate change is a shared threat that knows no national boundaries. It is well accepted now that in order to prevent a warming of more than 2 degrees Celsius (considered the absolute maximum of temperature increase without major disruptions to the climate system and many ecosystems), human-caused greenhouse gas emissions need to peak well before 2020, possibly 2015. There is no action towards this.
Sandy illustrates what we cannot tire of emphasizing: if we don’t want our climate system to spin out of control entirely, to the point of no return, then efforts to change must be made in all sectors and on all levels of human activity and interaction. From the individual to the local, from states and provinces to nations, from the regional to the global: we need change—political, technical, and behavioral change—wherever it can be achieved, as quickly as it can be achieved.
Sandy also whos how those communities that have begun to prepare for higher sea levels and stronger storms are faring better than those that didn’t believe this would be necessary. And despite our rapid nearing of the 2°C threshold, we should not forget how much worse the impacts of climate change might already be without the many actions that humans have taken to reduce greenhouse gas emissions. This can—and should—make us believe that, after all, change is possible.
