Global Warming  Global warming is the increase in the average temperature of the Earth's near- surface air and oceans

2 Causes of Global Warming  Methane While carbon dioxide is the principal greenhouse gas, methane is second most important. Methane is more than 20 times as effective as CO2 at trapping heat in the atmosphere.  According to the textbook it is because of the increase of greenhouse gasses

Greenhouse Effect  The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface.

2 Causes of the Greenhouse Effect  About 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space. The rest reaches the planet’s surface and is reflected upward again as a type of slow-moving energy called infrared radiation.  The textbook states that it is caused by gasses trapped in the atmosphere.

Ramifications of Global Warming  Climate Change, Rising Sea Levels, Glacier Retreat, and altered patterns of agriculture.  There will be a higher average temperature and a change in climate.

Ramifications of Greenhouse Effect  changes to the climate, changes to average and seasonal rainfall, storms and storm surges.  In the textbook it says without greenhouse effect there would be no life of earth..

Efforts to reduce global warming  hybrid engines, renewable energy, Energy Star appliances. The text book says to save energy.

Efforts to reduce Greenhouse Effect  Some ways to reduce greenhouse effect are to cut down less trees
