The climate system,crublands, has an entirely different feel about it from the tropical rainforest of Brazil, or the conifer forests of Canada. Vegetation is as important a part of the landscape as topography and the architecture of buildings, and yet it is an accepted and almost subconscious part of the order of thin

From climate to vegetation,y you might choose to subdivide them, there are between five and twenty fundamental vegetation types in the world. They include, for example, tropical rainforest and savanna in the tropics, and in the high latitudes temperate forest and steppe. Such broad-scale vegetation types are known as “biomes”

The desert makes the desert: Climate feedbacks from the vegetation of arid zones,imates that cannot support a tree cover, and their natural vegetation is open grassland, scrub or desert. There is no doubt that the location of these arid zones is largely dictated by broadscale geography (as we saw in Chapter 1), with several factors tending to produce dry climates.

Forests,nd good hunting for game. But they also took up space where crops might be grown, and provided a refuge for malevolent creatures both real and imaginary. As farming spread out from its first heartlands in the Middle East, northern China and Central America, forests began to lose ground. Already by t

Plants and the carbon cycle,s element is especially large quantities if they are to grow and maintain their tissues. Carbon-containing molecules also serve as a store of energy for cells to work; the bonds within the molecules are broken and energy is released. For these two purposes—building bodies and fueling them—organisms

The direct carbon dioxide effect on plants, on plant physiology. Since CO. is fundamental to photosynthesis, it makes sense that increasing the amount of CO. in the atmosphere will tend to allow plants to photosynthesize faster. This then is one-half of the direct CO. effect on plants. But there is also another less straightforward direct ef
