Facts, Causes & Effects
What is Global Warming?
Carbon dioxide emission from vehicles.
Cutting Down Trees
Cutting down trees reduces the amount of oxygen being produced, and increases the amount of carbon dioxide in the atmosphere.
Factories release carbon dioxide and other gases into the atmosphere, causing these gases to get trapped in the ozone.

What Causes Global Warming?
What Are We Doing To Fix It?
There is no single solution to global warming, which is primarily a problem of too much heat-trapping carbon dioxide, methane and nitrous oxide in the atmosphere. Some things that can be done to prevent, and slow down the process of global warming are:
- Reducing Fossil Fuel Use- There are two ways to reduce fossil fuel use: Use less energy, or use alternative, nonpolluting energy sources like solar and wind power.
- Planting Trees- Because carbon dioxide is the most important greenhouse gas, planting trees and other plants can slow or stop global warming. Plants take in carbon dioxide and release oxygen.
- Reducing Waste- Decomposing waste in landfills produces methane and other greenhouse gases. Recycling metal, plastic, glass and paper lowers greenhouse gas emissions, since recycled items take far less energy to manufacture.
- Conserving Water- Saving water reduces the amount of energy used. At home, turn off water immediately whenever you're not using it, and repair or replace leaky faucets and toilets.
Effects Of Global Warming
- One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.4 degrees Fahrenheit over the past 100 years.
- Changes in climate can cause the jet stream to migrate south, bringing with it cold, Arctic air. This is why some states can have a sudden cold snap or colder than normal winter.
- One of the most dramatic effects of global warming is the reduction in Arctic sea ice: In 2012, scientists saw the smallest amount of Arctic ice cover ever recorded. Most analyses project that, within a matter of years, the Arctic Sea will be completely ice-free during the summer months.
How Does This Effect Me?
- Food prices are rising as climate change makes it trickier to maintain the specific conditions crops need to thrive. As the climate warms, the air holds more moisture and rainstorms become more intense, damaging crops.
- Fresh water is becoming scarcer in some regions. Nearly 18 percent of the world's fresh water is found in the Great Lakes, which supply drinking water to a large region. Scientists expect lake levels to drop as the climate continues to warm up.
- More wildfires are breaking out as droughts become increasingly common. Fires that go through drought-stricken land spread more quickly and burn longer, destroying forests and homes, public recreation spaces and grasslands.
