Andy Ridgwell:[---2-3---] We also know that just how the leaves are exactly arranged in the canopy can make a big difference as to how much sunlight is reflected back from the crop.
That’s climate scientist Andy Ridgwell of the University of Bristol. [---4---]

A scientific study has shown that farmers could help curb global warming by planting crops with leaves that reflect more sunlight, and heat back to space.
We know that the composition and the amount of wax on leaves is important.
And the waxier the leaf, in general, the more reflective it is.
Using computer modeling, he calculated that crops with waxier leaves, which are therefore more reflective, would have a cooling effect on Earth, especially on major agricultural areas.
So In the summertime when the crops are in leaf, and they’re reflecting slightly more sunlight away, you get a cooling of maybe about a degree in North America and a degree in Europe.
He said that might not sound like much.
But it will take the edge off, you know, the frequency and intensity of heat waves which, certainly in Europe, are becoming a big issue.
Ridgwell added that seeds for crops with greater reflective power aren’t yet commercially available.
Plus, he said, it’s not known how food from these special crops would compare in taste and feel.
He said more research is needed.
