Ok, going out on a limb here, if u think im crazy just say so and ill go back into my hole and find more ideas to spit out at you. Climate change and anthropogenic climate change (NOTE i have put them as 2 separate entities) are some of the most sought after and researched topics in the world of science today, and effect everyone and their lives. For decades now, people have measured the CO2 and other GHG concentrations and the undoubtable consensus is that they are increasing, both naturally and due to human induced changes. This thread is definately not about the specifics of climate change. These kinds of threads have been started before and have turned into flame wars, and im not about to start another one. No, this thread is a dicussion of the possible dangers we all face if we actually do conquer climate change. Confused? then read on and i will try to explain myself. Firstly, what does it mean to 'conquer climate change'? Well, in my mind most scientists, the IPCC and several government agencies in almost every developed country and trying to find ways to reduce their GHG emissions and stop polluting the earth. It would seem to many then, that conquering climate change would involved limiting or eliminating emissions and trying to stabilise the earth system. This would in fact slow the rate the earth warms at current, eventually stopping it in the hope of decreasing it. Question no.1: IS THIS WHAT WE REALLY WANT TO DO? Do we really want to stop the heating of the earth? do we really want to cool the place down again? why? Ok, so assuming we do want to stop the earth heating, how do we do it? At the moment we only know 1 way - to keep heating the earth by putting GHG's and other pollutants into the atmosphere/oceans. i think this is a good thing. Not because we're heating the earth, i think thats bad, but because we can ONLY heat the earth, read on... Ok, so lets just say we find a way to negate and reduce the amount of GHG's and pollutants we put into the atmosphere (its not important how its done, just that it IS done). We find a way to do this on a global scale that cools the earth. Now not only can we heat the earth whenever we want to by adding more GHG's and pollutants, but we can also cool the earth when we want to by whatever method we found to work effectively. This is dangerous. You dont have to be a genius to see that people/countries/organisations will possibly be able to use this to their advantage. Some industry and economies thrive on decreased temperature, some thrive on warmer temperatures. Not everyone will be happy with what you do, you can please everyone. And then there is the possible terrorist connection. no, i dont mean people who wear toilet paper on their heads, have beards and blow up buses. I mean anybody who will be in control or have access to this technology and has a hidden agenda. If we know so much about the earth that we can heat it up and cool it down at will, then we can also affect other things about it too. For example, take the thermohaline circulation. some organisation could threaten to shut it down by releasing massive amounts of GHG's (will there be carbon credits and stores of carbon by this time? possibly). This would melt the polar ice caps, releasing massive amounts of freshwater into the north atlantic, shutting down the thermohaline circulation. if the THC was shut down, average temperatures in europe would warm by 6-7C. This is significant. Anyways, what i am getting at is that it is dangerous to have this sort of power where we control the climate the same way you do with your climate control in the car. yes sure, most people dont like the idea of the earth warming at this rate, but i think people will live to regret it when we can turn up or down the heat on earth and it gets into the wrong hands. discuss.
