Global warming affects people, plants and animals around the world in many ways, causing an array of short-term and long-term consequences, such as polluted air, warmer atmospheres, health ailments and extreme and unpredictable weather patterns. Global warming is thought to pose threats to environments and ecosystems on land and at sea. It may contribute to a rise in sea levels and cause floods, droughts and more frequent and severe hurricanes, tornadoes and snowstorms.
One of the biggest concerns of global warming is its potential to create extreme and unpredictable weather patterns. Primarily, weather patterns may take the form of prolonged periods of heat and dry weather, which in turn causes droughts, increases the risk of wildfires and poses threats to wildlife, fauna and economies by limiting or preventing crop growth. Another major threat of global warming is that it may pose significant health risks and consequences. It has the potential to increase levels of smog and urban pollution and may accelerate the spread of certain diseases and illnesses. Global warming has the potential to jeopardize the health and well-being of many organisms, including polar bears, which are at risk of drowning as the ice floes they use to rest on disappear. Lastly, global warming may cause glacial retreat and sea levels to rise.Learn More
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 >
Global warming certainly does exist and has since the first atmosphere formed on Earth. Some global warming has always been present and prevents the Earth from radiating energy back into space at the same rate it receives energy from the sun. When global warming is discussed in science and politics, it is often called anthropogenic, or "human-caused," global warming. This has also been demonstrated to exist.Full Answer >
The primary cause of global warming is the collection of carbon dioxide in the atmosphere. Carbon dioxide and other pollutants trap heat from the sun, making the planet warmer.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 >
