Document Summary
When we have more greenhouse gases in the atmosphere we have warmer temperatures. Changes in climate resulting from human activates at local to global scale. Coversion of forrest for crop production and live stock. Livestock produce lots of manure which increases the amount of methane in the atmosphere. Increase in greenhouse gasses are the major contributor to warming for the past 200 years. Faster rate of change in temperature than over past 10000 years. Observed value and climate models show greatest temperature rise: at high latitudes latitudes. Every degrees it gets warmer we face more issues, such as increases in water and sea level. Coast lines more subject to damage n floods. Snow cover has decline in the northern hemisphere: particular in spring and summer. Ice and snow coverage is decreases because its melting and the ice is melting. Over all less that 1. 3% decrease in snow coverage per decade. Cariboo having difficulty eating because of this too.
