PPT-Global Warming Climate Climate: the average weather conditions over a period of years

Climate is influenced by a variety of processes including geologic processes Volcanism Seafloor spreading Configuration of landmasses due to plate tectonics Climate changes impact geologic processes. will be held during the final examination period and in the regularly scheduled classroom unless special room arrangements are made with the Registrar Thursday Evening Classes Thursday December 11 Tuesday Evening Classes Friday December 12 Wednesday 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. . By Matthew and saeb . 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 . Learning Objectives. :. To understand the evidence for and against global climate change- World and UK temperatures for the last 100 and 1000 years. To know the causes of global warming.

Global warming is when the earth heats up and the temperature increases. More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment.. The Greenhouse Effect. Weather is the day to day condition of air at a particular place. .. Weather changes every day. . Changes in weather conditions give rise to seasons. In India we enjoy three seasons –summer, winter and monsoon. . Robert G. Strom, Professor Emeritus. Department of Planetary Sciences and Lunar and Planetary Laboratory. University of . Arizona.
