Concepts of Global Warming and Climate Change CENTRAL LUZON STATE UNIVERSITY COLLEGE OF BUSINESS AND ACCOUNTANCY Science City of Muñoz, Nueva Ecija 3120 1 Learning Outcomes ⊷To understand what is global warming “ and climate change , the differences, and the effects Climate change is real. ⊷ To discuss how did global warming The science is start, and how will it continue compelling. And the ⊷ To discuss what will happen to the longer we wait, the humanity with some negative effects of harder the problem the global warming and climate change will be to solve. ⊷To discuss some strategies to combat -John F. Kerry climate change, and the things you can do 3 4 1  What is Climate Change? What is Global Warming? ⊷ It is the change in our weather ⊷ It is the continuous increase/ rise patterns that are occurring of average temperature in the because of an increase in the Earth’s climate system earth's average temperature. 5 6 ⊷ Greenhouse gasses absorb some of the heat and trap it near the earth's surface, so that the earth is warmed up. This process, commonly known as the greenhouse effect. 7 8 2  Global Atmospheric Average surface temperature has Concentration of CO2 risen about 1.78oF (0.99oC), since the late 19th century As of May 2022, average global atmospheric concentration of CO2 was 421 ppm.
