Many people today believe that global warming is still nothing but a theory discussed by some weird scientists because they just want to scare us. But in reality there are many climate issues happening and people are very confused on what is really happening. Some theories of global warming are the “Green house effect”, changing sun, ash from volcano and natural variations in climate such as El Niño. Most scientists agree that global warming is caused by humans. Some solutions proposed to stop global warming are cutting emissions which hold heat. Using renewable energy and protect forests. Waiting another ten or fifteen years to start doing something about global warming is not an option anymore.
The “green house effect “theory of global warming is described as When CO2 and other heat-trapping emissions are released into the air, they act like a blanket, holding heat in our atmosphere and warming the planet. According to Union of Concerned Scientists (2010) Overloading our atmosphere with carbon has far-reaching effects for people all around the world more extreme storms, more severe droughts, deadly heat waves, rising sea levels, and more acidic oceans, which can affect the very base of the food chain. The primary cause of global warming is human activity, most significantly the burning of fossil fuels to drive cars, generate electricity, and operate our homes and businesses. Tropical deforestation, also by human hands, is another major contributor. According to Union of Concerned Scientists ( 2010) When these forests are burned, they release huge amounts of carbon into the atmosphere and because the forests no longer exist, they are no longer available to absorb CO2. To address global warming, we need to significantly reduce the amount of heat-trapping emissions. As individuals, we can help by being mindful of our electricity use, driving more efficient cars, reducing the number of miles we drive, and...
