Roger Bryant:
Whilst looking for something else I came across this piece on Cloud Climatology on the NASA GISS website. As one of the premier research institutes in this field they don’t seem to think we know enough. Here are some quotes:
--------------------------------------------------------------------------------------------------------------
•Clouds cool Earth's surface by reflecting incoming sunlight.
•Clouds warm Earth's surface by absorbing heat emitted from the surface and re-radiating it back down toward the surface.
•Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space.
•Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation.
•Clouds are themselves created by the motions of the atmosphere that are caused by the warming or cooling of radiation and precipitation.

Best regards

Bear in mind that tiny changes can make huge differences to the people on Earth.

The Earth is receiving massive amounts of energy from the Sun. Massive amounts of energy leak back out into space again. It's the precise balance of those that makes the difference between our present climate, an ice age, or the planet becoming too hot to live.
Roger Bryant:
Is installing solar panels produced using high pollution coal fired power stations in China really sensible? The only reasonable way would be a 'bootstrap' system where you only make renewable energy sources by using renewable energy. Any other way will cause a significant increase in emissions in the medium term.
