Vegetation Effect
Temperature is one of the
three major influences on global patterns of plant growth. The
Earth’s surface land temperatures are represented on a scale
between –25 degrees C and 45 degrees C with the darkest regions
the coldest and the lightest the hottest. Along with available
sunlight and water, temperature determines whether the land will
support dense forests, grassland, or nearly barren desert.
Conversely, plants influence how hot the surface of the land can
become. In areas where vegetation is dense, the land surface
temperature never rises above 35 degrees C. The hottest land
surface temperatures on Earth are in plant-free desert landscapes
where the dark regions are the most verdant and the light regions,
corresponding to the deserts are the lightest.
Land surface temperature is a measurement of how hot the land is
to the touch. It differs from air temperature because land heats
and cools more quickly than air. Hot land does however heat the
atmosphere and thus contributes to global warming.
It is an objective of the current invention to convert desert
landscapes to dense vegetation and thereby moderate the heating
effect of these deserts on the atmosphere, which in turn will
reduce global warming.
