Can We Terraform the Sahara to Stop Climate Change?
The conclusions drawn from this film include that grass is better than leafage for solar reflection - albedo.

This ignores the fact that solar absorption by darker leaves does not result in higher temperature. The solar energy drives the photosynthetic process so much so that forests can be cool enough to attract cloud cover with producing improved albedo.

The best species for ‘carpeting’ would have to be highly prolific variants of Rhododendrons. Deciduous varieties providing nutrition for both themselves and the year-round photosynthesising evergreens.

The challenge is for irrigation to keep pace with rapid growth.

Drawing Carbon from the atmosphere has to be a priority if global cooling is to include every possible mode of operation. Time is not on our side.
