Dear Ron Very large (eg 2TW - 20TW) wind installation will have effects on the climate system by changing wind patterns, though the scale is not yet I think well agreed; similarly large biomass plantations have albedo and evapotranspiration effects. They could thus be seen as fitting the Royal

I think that we can all agree that we have a global problem (excess air CO2, OK, and other GHGs) that will require effective actions whose sum effect will counter or remove the problem at a global scale.  Because all actions have risks, costs, negative impacts as well as benefits, we need to

Poster's note : This technique could be useful for tweaking the side effects of SRM. It's useful it works both ways. http://onlinelibrary.wiley.com/doi/10.1002/2013JD020707/abstract Keywords: stratospheric water vapor;overshooting deep convection;vertical transport;cloud seeding;geoengineering

It would be a mistake to believe that model calculations can offer reliable simulations of the factors affecting the stratospheric water vapour content. The requisite scales are not there, and there is still debate about the detailed physical and chemical mechanisms at work. On 18 February 2014
