Water plays a major role for our planet not only in its liquid form at the surface.
In the atmosphere too, it considerably affects our lives as well as weather and
climate. Clouds and rainfall are one example. Water vapor, the gaseous form of water,
also plays a prominent role on Earth. It is the most important greenhouse gas in
the atmosphere, without it the Earth would be a frozen planet.
~This knowledge is also of paramount importance for the general climate research.
The temperature of the tropopause decides on the input of water vapor into the
stratosphere: The higher the water vapor content in the stratosphere; the higher
the surface temperatures increase. Anthropogenic climate change also has an
effect on the temperature of the tropopause, and this effect could become more
evident in the coming decades.
