- Climate Change - Physical Factors
- Volcanic Activity
- Large amounts of volcanic dust can shield the earth from the suns radiation.
- For example, the eruption of Mount Pinatubo in 1991 caused a dip in global temperatures in the early 1990s
- Solar Variation
- Sunspot Activity
- Caused by intense magnetic energy.
- They are visible as dark spots.
- They can be as small as 16 kilometers and as large as 160,000 kilometers.
- They are usually in the range of 2,700 - 4,200 degrees Celsius.
- Sunspot Activity
- Milankovitch Cycles
- Changes in the Earth's movements and orientation can alter the amount of solar radiation reaching the Earth.
- Ocean Currents
- An El Niño event in 1982/83 claimed nearly 2,000 lives and global losses of an estimated $13 billion.
- Ocean currents move large amounts of heat across the planet
- About half of the CO2 added to the atmosphere during the past century by human activity has been absorbed by the ocean.
