climate control Crow
Here's another of those hastily made travel postcards sent by Crow after he viewed one of the proposals put forward by the Gates Foundation toward geoengineering a solution to Anthropogenic Global Warming. The device you see is a very very large vessel that will suck up ocean water and blast it into the atmosphere in an attempt to make clouds. Projects similar to this, called Albedo Modification, are proposed to reflect sunlight back into space through one or all of several methods. The wildest one is the idea of using orbiting space mirrors to deflect the sun's rays (unknown weather effects, fails to prevent acidifying oceans); another is to spray aerosols into the stratosphere (risk of ozone depletion as well as unknown weather effects and ocean acidification); cloud seeding by using atomised sea water (same possible negative consequences).
A number of other geoengineering proposals have been suggested including fertilizing the ocean with iron filings to stimulate plankton growth or pouring tons of ground limestone into the sea to absorb CO₂. The effects on the ecosystems by these methods are also unknown.
Naturally enough, Crow had some thoughts to share about all this that he appears to have written on a number of tiny scrolls that began arriving by carrier pigeon earlier today. Here are a few I've been able to decipher so far:
First and foremost, the idea of geoengineering is based on a fundamental misunderstanding of what climate is, and why it is important. Although I have the greatest respect for many climate scientists and engineers, most do not understand ecology, or have a particularly good grasp of it. I have not, for instance, found any of them flying with condors or guarding eagle nests.
The failure in thinking about geoengineering is it wrongly assumes that the only issue is temperature, and that if you simply bring the temperature back down, then the problem is solved. This is so ecologically naive that I may need a shot of brandy before I start. Ahh, there - deep breath. Even if geoengineering did manage to bring the temperature down, it is likely to fundamentally change how ecosystems experience climate, or have other serious ecological impacts - ones that are inherently unpredictable and likely to cause far more problems than they solve. Ecosystems don't just experience climate in terms of crude average temperature. There's the amount of sunlight, precipitation, wind strength, wind direction, humidity and so on. In crude terms, it would be creating another type of climate change.
Geoengineering is based on the credulous concept that the world is rather like a giant room, and you can just raise or lower the temperature, and the rest or room stays the same. In reality, ecosystems interact with the climate in very complex and circular ways. They not only are effected by climate, but they also effect the climate. The geoengineering concept is based on a fundamental failure to understand the dynamic and highly interlinked nature of the natural environment and natural ecosystems. Any whale or dolphin could tell you this.
Geoengineering is essentially a convoluted form of denial saying that humanity should carry on as usual, to the extent of taking absurd gambles to try and control the climate. Missing the 'big picture' entirely, this thinking does not take into account that the present economic model (and industrialization) is highly unsustainable, even if climate change never existed. There is ongoing massive biodiversity loss, ocean depletion, the depletion of natural resources like water, human population growing out of control, and a 1001 other environmental problems, which geoengineering will not address, and might make worse. It is an artifact of people who reject the idea that the global system has to change to make it environmentally and ecologically sustainable.
Anticipate my early return, dear susan, and a period of relaxed enjoyment when we can discuss these matters more fully. Meanwhile, you may feel free to share my thoughts with our friends. Please keep the brandy warm and the fruitcake moist.
ps: Perhaps they should try their experiments in an environment where no living beings are likely to be hurt - Mars, for instance.
On a lighter note, here's some video evidence that sometimes a regular person can make a difference. You can see it now and I'll show it to Crow when I see him:
The United Nations Climate Change Conference, COP21 or CMP11 will be held in Paris, France in 2015. The objective of the 2015 conference is to achieve, for the first time in over 20 years of UN negotiations, a binding and universal agreement on climate, from all the nations of the world.
Shall we keep our fingers crossed?
