By increasing the abundance of these gases in the atmosphere, humankind is increasing the overall warming of the Earth s surface and lower atmosphere, a process called global warming.. The figure below illustrates the radiation balance and the role of greenhouse effect. Illustration of the Earth s radiative balance.
The solar radiation intensity at Earth's surface is only about a tenth of what is experienced in Space at Earth's orbit. The Earth's magnetic field also redirects and removes much of the charged-particle radiation approaching Earth. A thick atmosphere of light molecules is an excellent protection against radiation. In fact, very light molecules such as hydrogen and helium are even better than heavier molecules to take out the higher-energy particles. Water is probably the most effective radiation shield of all. Unfortunately, there is no evident way of generating either a thick atmosphere (which requires strong gravity to hold it in place) or a blanket of water a couple of feet thick for habitats of any considerable size.
