Global warming is the process by which the Earth’s average atmospheric temperature increases over time. The Earth has experienced both global warming and cooling during its 4.5-billion-year history. However, the current rate of temperature increase exceeds that which occurred in the past. Many scientists suspect that the accelerated rate of temperature increase is the result of human behavior.Know More
The primary driving force behind global warming is the change in the chemical composition of the Earth’s atmosphere. By burning hydrocarbons, humans release elevated levels of carbon dioxide into the air. As the atmosphere’s carbon concentration goes up, the planet retains more of the heat from the sun. The process works similarly to the way a greenhouse does, which is why scientists refer to carbon dioxide as a “greenhouse gas.” Carbon dioxide is not the only greenhouse gas, but it is the most important one for humans to monitor. Methane, nitrous oxide and fluorinated gases also contribute to global warming.
Rising temperatures cause a variety of effects on the planet. While a few of these effects are beneficial, most are detrimental to the current balance of nature. For example, rising carbon dioxide levels may cause plants to grow more quickly, but the accompanying rise in temperature may cause the polar ice caps to melt, raising the global sea level.Learn more about Human Impact
According to the Environmental Defense Fund, humans are 95 percent responsible for global warming. The effects of global warming are caused primarily from the burning of fossil fuels and the deforestation of the world’s rainforests.Full Answer >
Several efforts have been made stop global warming, including campaigns to raise awareness about environmental issues, advancements in resource saving technology, scientific research and legislation. According to the Washington Post, a survey by the Pew Research Center for the People and the Press found many Americans favor changes made to stop global warming.Full Answer >
The National Wildlife Federation explains that global warming is thought to be caused by the greenhouse effect, which is the result of certain gases in the atmosphere trapping the heat of the sun and preventing it from radiating back into space. There are many gases responsible for this effect, including water vapor, carbon dioxide and methane. Artificially-produced chlorofluorocarbons, known as CFCs, are extremely effective greenhouse agents, molecule for molecule, but are present only in small concentrations.Full Answer >
According to GlobalResearch.ca, as of 2014, the fact is that climate is always fluctuating, and assuming that climate was stable prior to the Industrial Revolution is wrong. No human influence in the pattern of global temperature was detected, despite spending $50 billion to find it. No computer model is accurate enough to predict the future, and thousands of scientists have signed declarations stating they question the existing evidence.Full Answer >
