Hot Oceans

As the world population grows, and as (hopefully) larger numbers of people move from deep poverty into better living situations, we have to deal with the build-up of toxins in the biosphere. (For a discussion of carrying capacity see the previous post). The old adage the solution to pollution is dilution has limits based on the size of the container and the amount of toxins. As we saw two posts ago, a simple calculus used by environmental engineering is

Mass rate of accumulation = mass rate of input – mass rate of output.

We have to keep this in mind because, for all intents and purposes, (the bleed-off from the troposphere being so slight), we need to treat Earth as a closed system, in which we need to avoid piling up toxins too fast for the natural ecosystems to mitigate in their regular, natural rates. If we surpass this natural rate of breakdown to useful components, then we have to find ways to mitigate/ break down the toxins ourselves. For Christians with a biblical theology, this should be a conversation they deem important.

One of those things we are building up at a faster mass rate of input than the biosphere is handling, is heat. The amount of carbon being piled up in the upper atmosphere, acting with a greenhouse effect, is increasing the temperature in our world. Although Glenn Beck and Rush Limbaugh have convinced huge numbers of Americans that this isn’t really happening, every government in the world is scrambling trying to draw up plans to deal with this climate change. They are scared to death at what it means for crop failure, and nations with large coastal populations in low elevations see the writing on the wall. (Some South Pacific islands no longer have human populations, they’ve had to leave as their island is no longer above sea level – this is what happens when glaciers melt at the rate they are.) You can read about how the various gasses interact and feedback on NASA’s website here

The oceans are a telltale for the mass rate of input, in terms of heat, changing things about our planet. Ocean temperatures right now are breaking all historical records. Summer of 2014 was the highest ever recorded (Axel Timmermann, professor of Oceanography, U. of Hawaii). The Atlantic’s surface temps are now 3 degrees hotter than 30 years ago. NOAA reports that fish species are moving north and south away from the tropics, pushed by the change in temps. Inuit tribes north of Alaska do not have a word in their language for salmon, as they’ve never seen one. Until now. Half of the 36 species of fish we eat for food have shifted northward and further offshore in the last four decades, some no longer found in U.S. waters. When one species moves (due to temps) and their whole ecological food chain doesn’t move with them, disasterous population crashes can occur. Fishery managers are seeing alarming results of this kind of thing, and fearing it is going to get far worse. Widespread failures in cod reproduction have already occurred. A 20% crash in worldwide tuna harvest in the visible future. If anyone wants to argue heat isn’t building up faster than the planet deals with it, simply speak with an oceanographer or saltwater fisheries scientist. We need to be serious in considering this heat build-up if we want thriving oceans with stable, healthy ecosystems we can fish. Christians, who believe the Creator instructed humanity to steward, rule over, and care for this planet, have a moral obligation inherent in our faith to care about this subject, and go beyond taking the word of talented radio entertainers.

If Climate Change is Natural, Does that Change Anything?

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: ).

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.

Thinking in 50,000 year Intervals

Living on the road while we travel speaking about our transition to SE Asia as development workers/theological educators, I haven’t had a lot of time to think about the blog. But here is something I wrote a while back and not yet posted.

Something became apparent to me the other day.  I realized that many of my Christian friends approach today’s issues as if Jesus will return in 50 or 100 years, max. So if we just hold the line on this or that issue, just hold on, we’ll be ok. Other issues can be ignored, because they will never happen. I suddenly realized one of the reasons I often come to different conclusions than them is that I tend to think in 1,000, 10,000 or 100,000 year increments. What seems like a hold-the-line issue in the short-term, when thought about in vastly larger time frames, suddenly becomes very different.

I probably have science fiction to thank for this. It deals in large increments of time. When I think of the changing face of certain ethical questions and I see how Christianity has changed it’s take in the last 2,000 years, I can’t imagine we are going to freeze frame for another 20,000 or 100,000! Or when I think about say, climate change, if Jesus is coming back in 20 years, no big. We don’t live on Fiji, so loss of shore-line isn’t of immediate alarm to most evangelicals I know in Pennsylvania. But when I think in terms of 100,000 year increments, the question isn’t simply How do humans utilize advanced technology without heating the whole planet via emissions? Nor just, How do we steward the oceans so we don’t poison them utterly? (PS I like to fish). No, the questions include but go even beyond that, to How do we plan now for the settlement of the solar system, and beyond? How much do we invest now in a space elevator and terraforming Mars and the moon?  If the Ross Ice Shelf hits the water and sea levels raise 20 feet, how do we handle 2 billion displaced people? That, by the way, is a real and potentially immediate question, because we don’t know what the tipping point is to increase the rate of slide to the point the whole thing just goes.

Short term thinking can be incredibly disastrous. Proverbs highlights this in the Bible. But I rarely hear Christians in North America call upon their Christian faith to think long term. I find most of them assuming a very short length to human history, as if we are at the tail end. When we Christians limit our interests to the immediate future, can we blame other people for concluding we have nothing to offer for a long-term durable civilization?

Schumacher: the limitations of economics to reflect reality

“I’ll post it in a few days.” A few days! I am having trouble getting back to my blog as I am being subsumed under a wave of a zillion things to do as I wrap up my job pastoring a fantastic church in rural Pennsylvania, at the same time that I have another zillion things to do preparing for a move to SE Asia.

In any event, here is E.F. Schumacher’s quote, written in 1973, regarding the short-sightedness of modern economic activity: (Well, I think this is the one I had in mind 10 days ago!)

“Economics, moreover, deals with goods in accordance with their market value and not in accordance with what they really are. The same rules and criteria are applied to primary goods, which man has to win from nature, and secondary goods, which presuppose the existence of primary goods and are manufactured from them. All goods are treated the same, because the point of view is fundamentally that of profit-making, and this means that it is inherent in the methodology of economics to ignore man’s dependence on the natural world. (Note from Todd: you can monetize wood, but when there’s no forest left, money does not equal trees anymore).

Another way of stating this is to say that economics deals with goods and services from the point of view of the market, where willing buyer meets willing seller. The buyer is essentially a bargain hunter; he is not concerned with the origin of the goods or the conditions under which they have been produced. His sole concern is to obtain the best value for his money.

The market therefore represents only the surface of society and its significance relates to the momentary situation as it exists there and then. There is no probing into the depths of things, into the natural or social facts that lie behind them. In a sense, the market is the institutionalization of individualism and non-responsibility. Neither buyer nor seller is responsible for anything but himself.

….economists have felt entitled… to treat the entire framework within which economic activity takes place as a given, that is that is to say, as permanent and indestructible. It was no part of their job and, indeed, of their professional competence, to study the effects of economic activity upon the framework. Since there is now increasing evidence of environmental deterioration, particularly in living nature, the entire outlook and methodology of economics is being called into question. The study of economics is too narrow and too fragmentary to lead to valid insights…”

Chopping down Louisiana’s forests to meet Europe’s energy goals

Humanity’s original vocation in Scripture (never rescinded) is to steward God’s property, the planet. As a can’t-get-enough hunter and fisher, backpacker, gardener and all around nature lover, I’ve always been interested in our world’s biomes and their health. It’s one of the reasons I did an MA in International Development.

Western Europe wants green energy. Good so far. They’ve decided wood pellets are green. They call it “biomass energy.” Problem: Western Europe doesn’t have jack for forests. So they’re getting their wood pellets from the southeast USA. 2.5 million tons in 2008, which jumped to 9 million tons in 2012. They want 20 million tons annually by 2020. That 20 million tons annually is planned to come primarily from the US and Canada.

That’s a lot of clearcutting.

And as far as following established limits, in 2008 activist Dean Wilson traced bags of cypress mulch at Walmart and Home Depot labeled “sustainably harvested” back to the Atchafalaya Basin. The Basin’s cypress swamps serve as a hurricane-absorber for the coast, and are a refuge for all manner of wildlife. Due to the past, when Big Business says cypress aren’t being cut down, environmentalists are leery to believe it again. Plus, clear –cut areas can rejuvenate, but the biome for wildlife is catastrophically altered overnight, and the hurricane-mitigating abilities are wiped out until it grows back.

One questions is, how “carbon neutral” are wood pellets when used on this kind of scale?

Well, eventually, when the trees grow back, but it’s the next 50 to 100 years environmentalists are VERY worried about in terms of carbon in the atmosphere. It’s the tipping-point effects of the carbon affecting the planet’s temperature that we are concerned about now, not when the trees are sucking carbon at the rate they are now, 60 to 80 years from now.  For example, get the Ross Ice Shelf sliding faster off the Antarctic land mass than it already is… well, if that baby hits the water in one big slide, expect sea levels to go up at least 3 meters immediately. Result? Among other things, several billion people as refugees around the world, and US Senators will lose their beachfront homes.

To a large number of  American evangelicals, many of whom expect the Second Coming any minute since President Obama won a second term and their kids listen to rock music, the whole global warming/climate change discussion is a conspiracy for communists, the UN, or the Anti-Christ (or all 3) to take over the world. As a result, they’ve opted out of any serious engagement in the climate change issue, citing that they still love nature “I like going to the lake as much as the next guy…”

But for those of us Christians concerned about environmental issues, as for the wood pellets in Europe:  Is this an example of what we want to call ‘green’?
