Document Summary
Release sulfur dioxide which, when mixed with water, produces sulfuric acid. The eruptions increase the albedo of the atmosphere. Short lived effect: decrease in the global temperature (0. 2-0. 3 ) then the global surface temperature gradually starts to increase: ghg and anthropogenic forcing. Huge increase in methane; more methane in the atmosphere now than co2. Change in climate resulting from human activities at local to glocal scale. Industries, transportation, land clearing, and livestock productions increase the amount of ghgs in the atmosphere. Faster rate of change in temperature than over the past 10,000 years. Observed values and climate models show greatest temperature rise. Mitigation: the action of reducing the severity, seriousness, or painfulness of something. Increase in precipitation expected in the northern hemisphere (usa latitude and above)(tip of south america latitude and below) by 2100. Decrease in precipitation between s. a and usa latitudes by 2100. All of north america is becoming more dry: the impacts on low-lying areas.
