Global warming 101 - Part 2: How plants cool the Earth

Depite that CO2 gets all the blame in causing global warming, Nature is much more complex than just one element. In this video, you'll learn how plants govern hydrology, i.e. movement of water in the environment. And how they can cool the earth by keeping the surface covered as well as by breathing. Plus, they can create clouds and cause rain, cooling the planet even more.

The problem is that the albedo of dry soil or sand is between 20% and 35%. The albedo of plants is between 8% and 20%.
Thus more heat is absorbed by plant covered terrain.

That is true from one perspective, however, the situation is much more complex in climate and heating the planet - nothing is as simple as just albedo effect - otherwise, deserts would be cooler than rainforests... Plants by breathing remove some of the heat. Plus the constant release of water vapour and bacteria from plants also draws cooler air of low pressure and brings about clouds and rain, bringing with it more cooling of such land. On the other hand, the hot air over deserts creates a high pressure dome which cannot be penetrated with cool low pressure air. So deserts become unbearably hot and as the surface becomes hotter and hoter, more heat is being reflected into the surrounding air, making it hotter too. I'm sure you've felt the difference of walking on hot sand versus on gras-covered soil.

Luckily, with the increase in CO2 the world has become much greener. Greening of the earth.
