It never ceases to amaze me that two radio entertainers have convinced a majority of Americans that Global Warming is a hoax, although it happens to be a hoax that nearly every government on planet Earth believes is true, and is working to address. The immense confidence my fellow citizens have in these two entertainers is astounding. For sure, they are talented.
However, there is now another tagline alongside the hoax argument, and that is that climate change is a purely natural phenomenon and so our use of fossil fuels (57% of the carbon dioxide released currently) shouldn’t matter. (What we do and don’t know about climate change is summarized pretty handily in this BBC article: http://www.bbc.com/news/science-environment-24021772 ).
So let’s consider the “it’s only natural” argument for a moment. First, certainly that is in part true. We know, from analyzing a variety of materials, that Earth’s climate has been both hotter and colder in the past. The polar caps on Mars were melting/shrinking/subliming the last few years, and of course my Chevy Silverado’s engine didn’t cause that.
However, it is also certain that we are releasing unprecedented amounts of CO2 in the last hundred years, and it’s a powerful greenhouse gas. No one wanting to be serious should argue that increased greenhouse gas doesn’t contribute to the rise in temperature.
But if the temperature is climbing anyway (increased sun output, etc), should we bother trimming back on our contribution? Let’s think about that.
When it gets colder outside, I put additional wood on the fire. I mulch the flower beds deeper, wear an additional layer, and maybe add a layer of insulation to the attic. When there’s a drought in the summer I don’t water the lawn, and pay extra attention to when I water the garden. When the average frost line dips south, farmers look to more cold-resistant strains of grain. (At the moment, world governments are looking at heat resistant strains, and planting further north). In short, we make adjustments to our life due to climate all the time. Even when the changes are natural.
So, if climate changes are largely natural, should we do anything with our lifestyles? Several questions arise for North Americans, even if you leave out moral questions about how our decisions affect Fiji, Indonesia and sub-Saharan Africa. First, do you like Florida? Because if the West Antarctic Ice Sheet goes off the landmass and into the water, Florida will no longer be above water. Goodbye. And one of our problems is that we simply don’t know when the tipping point in that slide is reached, so it’s hard to know if we are very close to danger in that area, or not. How about East Coast cities? Have you watched the news on this? The numbers of East Coast cities dealing with tidal flooding and writing up emergency plans for such is growing monthly. These are cities that never dealt with tidal floods in the past. Or consider the wheat belt in Kansas, et al. There is extreme concern of catastrophic crop failure due to a spike in temperatures. Your croissants are going to get very expensive. So expensive, that Bill Gates has already funded the 30 kilometer high balloon-lifted hose that would spray silicates into the high atmosphere to shield us from sunlight. It’s the most popular of the ‘geo-engineering’ projects being debated by world governments as we speak. Sound like science fiction? The money has already been spent. Governments have been discussing it in deadly earnest for some time now. Do you like coral reefs and seafood? Because industrial acidification is killing off the coral reefs, and we know this for a fact.
As a Christian who believes in the stewardship God placed us in over His world, I believe we should be a serious and thoughtful voice at the table these days as we try to figure out an appropriate response to climate change. My brother-in-law in Kentucky, a very wise follower of Jesus, said to me not long ago when I asked his opinion on all this, “I’ve always believed you should clean up any mess you’ve made, and avoid making a mess when you do something, if you don’t need to make one.” Good common sense.
So, in a word, here’s what I suggest is worth talking about: even if climate change is purely natural, it is very worth our time thinking together about how to adjust our contribution to it, because our contribution is exacerbating a situation that is already going to make life here more difficult. If I knew fire-danger was at an all-time high one summer, everything dry as a bone, and we had 25 mile an hour winds, I’m not going to burn a brush pile that day.
