    spot, I am so disappointed you did not include the "albedo effect" in your spiel.
    You missed a prime chance.

    The watch of your vision has become reasonable today.

    It’s normal. You must provoke. You must insult the belief of all monotheists. You must make fun of the belief of all monotheists.

    My guide to global warming:
    1. Sell off beach front property, people are still buying it and there is a good market.
    2. Purchase property on high grounds, hills, mountain sides. This will become the high value properties in the future.
    3. Don’t buy in flood plains. (why anyone does anyway still amazes me).
    4. Countries with high amounts of fresh water lakes and have lots of rain need to invest in infrastructure and build large water reservoirs and good quality filtration systems. Fresh water will be the next natural resource commodity.

    That was slightly abrupt but I was dashing for the door when I posted it.

    What I mentioned of the "albedo effect" in my spiel was:
    Lots of clean white Polar ice cover promotes a cooler steady state. Lots of white fluffy clouds promote a cooler steady state.
    Admittedly it doesn't mention dust but I'd be interested to know what you think I left out.

    I haven't seen this before. Pretty last resort, but better than nothing I suppose:

    Professor John Shepherd, a researcher from the University of Southampton, chaired the Royal Society's geo-engineering study.

    He said: "It is an unpalatable truth that unless we can succeed in greatly reducing CO2 emissions, we are headed for a very uncomfortable and challenging climate future.

    "Geo-engineering and its consequences are the price we may have to pay for failure to act on climate change."

    My favourite would be the superfine membrane at the L1 Lagrange point. It would need a fairly significant weight inbound of it to compensate for the pressure of the solar wind but could be sufficient to cut the incident radiation by the few percent we'd need to stabilise the climate.

    You're not keen on maintaining a permanent artificial sulphate mist in the stratosphere then?

    Re: spot's beginner's guide to Global Warming

    So, finally we have an update.

    The UK government has announced the country will have zero percent carbon emissions by 2050. There is a plan, there are targets, there is a fixed deadline. All to the good, one might think. Besides, it might placate the rioters.

    I've always been an avid reader of New Scientist, a UK equivalent to, say, Scientific American but without the jokes and adverts. Up until I was thirty the New Scientist was prone to run editions dedicated to all the signs that the world was slipping into a new Ice Age, of which there were lots. Signs, that is. Then the focus fell on rising atmospheric carbon dioxide and the greenhouse effect. Perhaps we had dodged the Ice Age solely as a result of industrializing. I only mention this because the rioters blindly claim that global warming is a bad thing. I think the jury is out on that, but I do agree with them that it's quite definitely happening.

    So, the 2050 UK target pledge. I have three observations to make.

    One is that we haven't pledged the planet will achieve this goal, just that the UK will. My eye is firmly on American Exceptionalism as I say this. It makes bugger all difference what we do in the UK if the bloody Americans keep pouring vast quantities of greenhouse gases into the air. Will we see Americans act for the benefit of humanity beyond their shores? Will we hell as like, the notion is pure comedy. America is, after all, Exceptional. The US of A may well be pleased someone's cleaning up the mess but it's not going to chip in for anything other than increased arms spending to protect "Freedom".

    The second thing is that, even if the world did manage to achieve zero percent carbon emissions by 2050, the fine print hasn't been publicised. What "zero percent carbon emissions" means is that by 2050 the amount of carbon dioxide entering the atmosphere will balance the amount being removed. The level of carbon dioxide actually in the atmosphere will be at its maximum since lord knows how many millions of years ago and it will stay at that record level. The only thing which will reduce the level will be a negative value in this perverse measure that's been chosen. There needs to be less added than is being removed, at which point the record high will start to reduce and we can start to predict how much further we need it to fall before we can say we've made real progress. Nobody has even discussed how to do that, all they've discussed is bringing the rise to a fixed maximum instead of letting it continue upwards.

    My final point is that the 2050 pledge relates to carbon dioxide. There are several other greenhouse gases. As ForumGarden discussed over ten years ago, if the methane clathrates under the tundra and coastal oceanic seabed start a runaway entry into the atmosphere, we'll have triggered an immense positive feedback loop. At that point carbon emissions will be a trivial irrelevance. I did try pointing this out to Paul when he was here but he wasn't in a listening mood during that decade.

    I actually drove by that same area this morning and there seemed to be more cattle and calves which should come as no surprise as it is a big parcel of land and the picture shows a small part. Actually does not very much like captivity. Lots of food and land and protected by the rancher.

    After thousands of years they are dependent on people, in return for their protection and leasury lifestyle, we eat them.

    I suppose we should be thankful for the wooly mammoth for ending the last ice age.
