Climate change is the critical alteration in the measures of
climate, such as temperature, rainfall, or wind lasting for an drawn-out
period. It can result from factors more
recently from human exercises through greenhouse gas emissions. The
"greenhouse effect" changes the composition of the atmosphere and traps
heat increasing the global average temperatures. Snow and ice, which helps
regulate the Earth's surface temperature, melts and fills reservoirs and other
bodies of water, causing a rise in sea level.
