The climate system of earth includes the biosphere, lithosphere, cryosphere, hydrosphere, and atmosphere.

The greenhouse gases that we hear about are actually important for the earth's ability to remain warm enough to support life on the planet. With too much greenhouse gas however the earth would become too hot to live on. Greenhouse gases are rising because of things that people are doing on earth.

The United States contributes 25% of the carbon dioxide in the atmosphere, and is at the highest levels today than in the past 800,000 years.
|
|
In 1910 there were 150 glaciers in the Montana Glacier National Park. Today, because of climate change, there are only 25 glaciers remaining.

Global warming can cause hot temperatures where it used to be cold and cold temperatures where it used to be warm. This disrupts the life cycle in many regions and could result in increased water levels and flooding around the world due to melting ice caps. Only 1 yard rise in sea level would result in more than 100 million people losing their homes and communities.

When climate change results in habitat loss, species and plant life can become extinct.

|
Cutting down on meat consumption would result in decreased methane gas emissions and decreased damage to the climate. Cows produce even more methane gas than the oil industry - and millions of cows are grown for meat consumption.
|
|
The United States is working to reduce greenhouse gas emissions but some countries - China for instance - is planning on building even more coal plants for the next 10 years, which will contribute to additional greenhouse gas emissions.

|
The beginning of the Industrial Revolution changed the ocean's acidity. As of now it has been increased by 30%.
|
|
The first scientist to comment on fossil fuels and their potential to cause global warming was Svante Arrhenius in 1896.
|
|
The Antarctic and Greenland ice sheets have been melting, losing up to 60 cubic miles of ice (from Greenland), and 36 cubic miles (from Antarctica) each year from 2002 to 2005.
|
|
As climate change occur the number of extreme weather events and their severity rises.
|
|
Governments and people have to make serious changes to the way we live to reduce greenhouse gases and to reduce the effects of global warming and climate change for future generations.
|
|
Scientists believe that if they can cause global warming on Mars they can make it a liveable planet.
