Video: Foresight Report on Migration and Global Environmental Change


you miss the momentous report on “Migration and Global Environmental Change” released by the UK’s Government Office

for Science’s Foresight Programme? Have you been living under a rock? No worries. You can read a short summary by the UK’s Government Chief Scientific Adviser John Beddington, or you can catch the video below.

    Chem Flunky,So Let me get this straight, you have no idea how many dthaes will occur or have occurred? So if this is the case, let me ask you how you would actually proceed. You have a trillion dollars. You can spend it on saving known lives at risk for any number of problems man faces or on reducing AGW, which do you spend it on? Listening to the scare-mongerers, it sounds like it will be billions. Is this realistic? DO you think a good risk assessment can be done, if we do not even know the risk? My answer to this question is simple. Since we do not know the risk, we go for solutions that will be beneficial outside of AGW causing dthaes or not. Nuclear power is an example. We can make nuclear power cheaper than coal and it is already safer than coal. E-cars is another example. Not paying for gas would be awesome. If they can get the price of solar panels to a reasonable amount, it would be as well. Paying for half as much energy and not being totally reliant on the power companies would be great. Note that this solution without the constant scare-mongering, both addresses your issues and does not cause people to believe the world is going to end. Without the scare-mongering, do horrific things like denying third world countries, power plants become unthinkable. Also for your answer to Number 3, are you really suggesting that the earth will not naturally pull excess CO2 out of the air? We may disagree on the timeframe to do this, but your answer suggests that the earth will not pull excess CO2 out of the air at all.I understand why you say a thousand years. They have given the half-life of CO2 in the atmosphere at up to 200 years, meaning that taking out 97% of the CO2 would take about 1 thousand years. Fortunately for us and unfortunately for the scientists trying to determine the length of time, this is not nearly an accurate way of measuring this. Imagine a sink where the drain is pulled, but water is coming in at a faster rate then it is going out. Now in this case, if you lessen the water coming in, then the time to for the level of water to go down has to do with the rate of water going in and going out. It has nothing to do with how long one molecule of water stays in the sink. In fact, the time of a molecule of water being in the sink will likely be much longer. Because of this, it is difficult to figure out rates, but it will be far less than 1000 years.
