Document Summary
Climate and weather processes have affected humans for many centuries. Make the growth of crops nearly impossible. Heavy rainfall in mountainous areas may lead to downslope mass movement which destroy settlements and may lead to the loss of human lives. Result in the loss of timber (important economic resource) Can lead to loss of property in regions where cities and villages are located near dense forests. Change in climate resulting from human activities at a local to global scale. Ie the change in chemical composition of the atmosphere has impacted the equilibrium between the atmosphere, the ocean, and the biosphere. Can determine the concentration of co2 from 1000 years ago using ice samples which trap little air bubbles from the atmosphere. There has been a rapid increase in the atmospheric concentration of co2 in the past 200 years. Led to an increase in the amount of energy trapped at the earth s surface.
