Many people consider that Global Warming is the greatest environmental threat of the 21. st. Century. . However, during the 80s and early 90s scientists argued about the causes and effects of global warming. . Radiative. Transfer of West Atlantic Cumulus. Chang Sun. 1. , . Jiaxi. Wang. 2. , . Shuwan. .

What is global warming. Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. By Amanda Vang and Sydney Billington. What is Global. Warming?. Global warming is a when the earth’s temperature increases and it can change the earth’s climate permanently. Released greenhouse gases, increased amount of carbon dioxide, burning fossil fuels and human activities such as driving and cutting down trees and plants can cause global . Robin Hogan.

More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment.. The Greenhouse Effect. longwave is calculated by combining the output of two longwave sensors. Net shortwave is calculated separately by combining the output of two shortwave sensors.
