Hi All The evaporation from the Ron Ace spray will certainly remove latent heat from the atmosphere but exactly the same amount of heat will be returned when the vapour condenses as rain somewhere else. While it remains as water vapour it will be adding to amount of the greenhouse gases and

Alvia Stephen - One energy efficient arrangement would involve wind pumps on windy dry coasts. Direct wind is a great way to pump water, especially when you want to move more water to obtain more evaporation at higher wind speeds. You don't spray the water into the air, that is not energy

Steve et al., I have performed some climate model simulations of this idea (holding off on assessing its engineering feasibility). Let us recall that evaporating water has several possible effects, some of which are: 1. It cools locally by transport latent heat away from the surface 2. It

What will be important to explain is how water vapor feedback can be so strongly positive with CO2 induced warming, and yet on its own would be negative‹what aspect of the positive feedback cycle is being canceled out (e.g., it seems as if the intent is to exceed the water flux created by the

Hi, I tried to add everyone to the new Climate Intervention googlegroup as a default, but google overrode me and sent it out as an invitation requiring response. So, if you want to join the Climate Intervention googlegroup you need to do something active. Either click the link on the bottom of
