causes and evidence of climate change
Deforestation
Logging and clearing land for agriculture
roads increases the amount of C02 in the atmosphere
less photosynthesis occurs
Solar Output
Sunspots increase from a minimum to maximum every 11 years
Fewer sunspots were observed during the coldest period
Solar output has barley changed in the last 50 years
Fossil Fuels
Burning fossil fuels releases carbon dioxide
Accounts for 50% of all greenhouse gases
Volcanic Activity
Volcanic aerosols reflect sunlight away reducing global temperatures temporaily
Agriculture
accounts for 20% of greenhouse gases
Larger populations and demand for meat and rice will increase its contribution
Orbital changes
The suns energy is on the earths surface changes the earth
its axis is tilted on an angle and the earth isn't spherical
