The Earth’s atmosphere is a layer of gases surrounding the blue planet and which is retained by the Earth’s gravity. It reaches over 560 kilometers from the surface of the Earth. It contains about 78% nitrogen and 21% oxygen, trace amounts of other gases, and of course water vapor. The mixture of the above gases is known as air. The atmosphere protects life and health on Earth by absorbing ultraviolet solar radiation, absorbing infra-red radiation, and reducing temperature extremes between (...)(read more...)
During the 21st Century, CO2 concentration in the atmosphere is to increase considerably causing global temperature increase. Few degrees increase in the atmosphere can have serious consequences on public health and diseases re-emergence and diffusion. For example, tropical diseases could increase in mid-latitudes, since mosquitoes and other disease-carrying insects may found appropriate climate and environment.
Warming/cooling trends can be due also to natural cycles or low-frequency (...)
