Climate Change and Soil

This article talks about how climate change affects the soil's ability to absorb water, mainly regarding increased rains.

Locally I've noticed an increasing tendency of the soil to form cracks during dry spells, and they no longer close quickly with a good rain.  It takes days and days of generous rain to make them close now.  This is not a good thing.

On the bright side, humans are good at improving soil when they bother to do so.  Adding organic matter solves a wide range of problems.  If soil does not have good drainage, sand or fine gravel may be added.  Another excellent trick is to plant daikon radish, which forms an arm-sized root.  If you let it die instead of harvesting it, you have an arm-sized insert of organic matter in the ground, which helps aeration and water absorption.
