Why we should be excited if global warming is true.

    I've seen this story floating around for a few days now. It instantly reminded me of being taught at school that we are overdue for another ice age. Now this is like being overdue for an asteroid hit or a big super volcano. They don't come regularly like the sun coming up.

    But as we get to understand things line ice core samples, geology and the effects of the sun, planet rotation and wobble (how often can you use the word wobble in a serious post :p: ) along with the position of other planets... Well we are starting to be able to understand how these things interact. We can look for patterns especially any other period of time that mimics our current variables.

    It is looking likely that if human made global warming is happening the most likely thing we are doing is postponing the next ice age. Now if this is true then surely the trick is not to return the earth to it's normal cycle but instead learn to safely and cleanly control the makeup of our atmosphere to keep it at a nice stable level. After all people in Scotland would find it hard to move around under a kilometer of ice. Also you would not want to try and squash the population into a smaller space, we are running out of land anyway. So the obvious goal should be to try and protect the planet from an ice age at all costs.

    We seem to have found good warmers like cfc's, and there is a lot of research on plankton to use the sun and sea to produce a way of removing elements from the atmosphere.

    Thats not to say I'm promoting the current system. Pollution is bad, global warming or not, and we need to learn to monitor and control the chemicals we release into the atmosphere. Then we can control the atmosphere makeup from safe locations extracting or releasing elements as required.

    This technology would almost likely be very useful in the event of a big spike in volcanic activity. Maybe we would have a chance to scrub all that crap out of the atmosphere so we can grow crops outside. We are almost certainly at a technology point where at least some of us can survive almost anything thrown at us, providing we have enough warning to build the needed equipment and buildings.

    So surely it's the time to stop arguing about if we are warming the world and begin controlling our atmosphere and more open data on what is being added to the atmosphere, both man made and naturally. Along with what we are taking from the atmosphere.

    Set up processors to convert dirty pollutants into useful resources, use robotics to sort and recycle all waste and harvest most of our energy from the environment and safe nuclear.

    Typically its the new kings and lords of the manors that are putting their greed and war machines before allowing the scientists to help make life better for the masses. History does tend to repeat it's self. Has the internet, open source software and hardware, 3D printers and a whole range of sensors and output devices given us the tools to bypass the money men and crowd source science on a scale never seen before?

    Is it time we stopped waiting for those that 'lead' to fix the environment and just get on with fixing the environment....

    Power to the people!

    We are certainly due an ice age. There is a researcher named William Ruddiman who believes Neolithic man staved off the last ice age by cutting down forests and starting agriculture. I just read a book which referred to him saying that humans had per capita more effect on the climate then than they do now. I believe he coined the term Anthropocene to refer to the age we live in now, rather than the Holocene, because human activity has now had a permanent effect on the geological record.

    I read another book recently about weather and climate. I was shocked to read the effect the mini ice age in the seventeenth and eighteenth century had, particularly on the Scots. IIRC there were parts of the Highlands where the oats crops failed seven years out of eight and a third of the population died. In other parts of the country, the deathrate exceeded the birthrate for seventy years, and the average age for a woman to marry was thirty. Those sound like hard times.
