ENVIRSC 1A03 Lecture Notes - Lecture 7: Sulfur Dioxide, Northern Hemisphere, Main Source
Document Summary
Sulphur dioxide with water sulphuric acid. Drop in gobal temperature: 0. 2 to 0. 3 degrees. Climate of the past 1000 years, the temperatures were higher in the past 200 years. 1400 to 1800 there was predictions it was the return of the ice age. The man made increase temperature increased greenhouse gases and increased the temperatures: ghg and anthropogenic forcing. Methane and nitrogen oxide you can see the increases. Change in climate resulting from human activities at local to global scale. By the early 1990s there was a change of 0. 7 how in 2016 we are closer to 0. 8. Natural factors changes the amount of insulation. Sulphuric acid from volcano"s that increased the earth albedo. Pollution increased the amount of sulphate in the atmosphere, which cooled down the earth atmosphere. Some of them do contribute to the cooling of the earth atmosphere because of the increase in the earth albedo. **greenhouses is the main contributor of the global temperature change**
