Much has been made in recent days about science that either supports or does not support the idea of global climate change and its resulting effects. Laying aside the strictly scientific questions, this post considers whether the sustainability movement needs global climate change in order to be relevant to America and the rest of the world.
The most recent news item surrounding climate change has nothing (and everything) to do with the Copenhagen negotiations coming up next week. Hackers were successful in stealing e-mails from the University of East Anglia's Climatic Research Unit (CRU) that show some of the leading climate scientists in less than a flattering light. Aside from the personal shortcomings that may come off in the text of the e-mails, there has also been a wide amount of controversy surrounding phrases that seem to suggest that climate science isn't the bedrock of truth that we might think it is.
The object of this post is not to explore whether or not the climate science is solid or whether or not the faith that has been placed in climate scientists is merited. Instead, the controversy has sparked another question: if climate change isn't happening, what would that mean for sustainability? Or more appropriately, does sustainability need climate change in order to remain relevant?
To those who have a rock solid faith in climate change science, this may seem like an absurd question to be considering. "Why not," they might ask, "spend time focusing on defending the climate science instead of wasting time responding to situations that are not true?" The reason I have decided to speculate on this topic is two fold. First, I have no ability to defend the raw science of climate change. Secondly, the question I am proposing is absolutely vital to advancing the sustainability framework in the minds of those who do discount climate change. Right or wrong, a wide portion of the population does not believe climate change science is accurate enough. Advocates of sustainability must have an answer for why their way of viewing the world is still relevant. One would hope that sustainability has more than just one leg to stand on.
Admittedly, the recent advancement of the sustainability framework owes a great deal to the discussion surrounding climate change. Most of the time, in popular media and in politics, sustainability and climate change can seem like interchangeable topics. A reasoned examination of both shows that neither is interchangeable with the other. Although, if climate change is real it would be a large portion of the sustainability framework. Still, sustainability covers our entire interaction with the environment including sub-divisions that are related to the ideas of climate change but are robust enough to stand on their own. These are the issues such as natural resource depletion, water shortages, toxic chemicals, our disposable society, and the protection of biodiversity. All of these issues fall under the umbrella of sustainability.
So the answer to our question is easy in one sense. Does sustainability collapse when climate change is eliminated from the picture? Of course not. Many environmental issues remain that provide sustainability sufficient reason to be a foremost consideration in our time. A more interesting and difficult question to pin down is this: does sustainability need climate change in order to remain as pressing and immediate a concern?
This circles back to the reality that without climate change, sustainability would not have risen as quickly as it has to the forefront of our culture. Climate change, rightly or wrongly, ignited a concern in people that immediate action was needed on environmental issues. It is fair and right to say that without climate change, sustainability may not even be on the radar screens of businesses, citizens, and governments. It is also fair to say that while some of the time lines for action on other environmental issues are pressing, none pack quite the emotional punch of the worldwide flooding, natural disasters, and talk of a return to another ice age that climate change conversations entail.
So it is certainly easier to get people to pay attention to sustainability if they are already concerned about climate change. Remove the support of climate change concern and sustainability more than likely drops off the map for many people. Therefore to remain relevant, advocates for a more sustainable method of living will have to put in extra work in order to make a case that doesn't include climate change. Should they? My answer is unequivocally yes. Make the case that sustainability is essential, regardless of what an individual might think about climate science. A more clear way of looking at this might be this: set aside all the debate over climate change and think for a moment how un-sustainable California's water supply and delivery system is. This is a real environmental issue that sustainability has much to say about. The input of the sustainability framework on the water resources issues in California is good input regardless of climate change.
Climate change should continue to be investigated honestly by the best and brightest minds in the scientific community. But to make sure the baby isn't thrown out with the bathwater one day, sustainability advocates would be wise not to pin their entire movement on climate change science. Even legitimate science could one day be rejected by policy makers. Sustainability proponents should take a lesson from investment advisers and diversify, diversify, diversify. There are plenty of reasons to keep up the push.
