Human causes of rapid Climate Change

Emission of Greenhouse gases and their sources

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.

Global Warming

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Temperatures Will Continue to Rise

It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.

Frost-free Season (and Growing Season) will Lengthen

Change Will Continue Through This Century and Beyond

Changes in Precipitation Patterns

More Droughts and Heat Waves

Hurricanes Will Become Stronger and More Intense

Sea Level Will Rise

Deforestation

Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund.

Overgrazing

Sustainable Development

Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves.

Sustainable development is the idea that human societies must live and meet their needs without compromising the ability of future generations to meet their own needs.
