PPT-Global Climate Change Chapter 13-3

Some of the infrared radiation passes through the atmosphere and some is absorbed and reemitted in all directions by greenhouse gas molecules The effect of this is to warm the Earths . According to the Intergovernmental Panel on Climate Change rising global temperatures will very likely increase the frequency and intensity of heat waves droughts and heavy rainfall events adversely affecting agriculture forests water resources indu Earth Temperature Anomaly.

But while some concentration of atmospheric greenhouse gases is essential to life, too high a level could spell disaster. “ . What part do Church investments play?. Human-induced climate change. The earth’s atmosphere is warming at an alarming rate.. Overwhelming scientific consensus is that the cause is human activity – primarily burning of fossil fuels. . Created and presented by Brandi graham. What is global warming and why is it happening? . Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. resources of the western U.S..
