What’s At Stake
Global warming refers to an increase in the average temperature of the Earth’s atmosphere and oceans over time. This temperature rise is the result of an increase in carbon dioxide and other greenhouse gases, including methane, nitrous oxide and aerosols, in our atmosphere. (For more information on the basic science of climate change, visit GlobalWarmingSolutions.org.)
There has been consensus among scientists for years that global warming is a serious problem and that it is caused by human activity. If left unchecked, global warming, also known as global climate change, could have devastating effects on our health, economy and way of life.
An increased global temperature will shift ecosystems. Glaciers will retreat, altering water supply for habitats and millions of people. Global warming is already affecting how some people live, from “climate refugees” in Bangledesh to an Alaskan village that was forced to relocate.
Plant productivity and vitality will change, destroying fragile ecosystems. The record highs of atmospheric gases are the result of burning fossil fuels, clearing of land and agriculture activity. According to most experts, the sharp increase of dramatic warming in the past 50 years is attributable to human activity. In the United States, energy-related carbon dioxide emissions, resulting from petroleum and natural gas, represents 82 percent of our total human-made greenhouse gas emissions.
Global warming is more than just glaciers and polar bears. The Great Lakes is the largest freshwater body of water on the planet, the single largest source of surface fresh water in the world. Scientists estimate that the lakes are warmer and water levels are declining, with no end in sight.
Although climate change is already causing deleterious effects for many people, we can stop more damage from occurring. Solutions come in many forms, from small personal actions to federal climate legislation. To see what you can do to help, visit GlobalWarmingSolutions.org.
