Global Warming

Global warming is a complex issue facing our society today. The greenhouse effect is a main cause of global warming. When the sun's radiation reaches our atmosphere, some of it reflects outward into space while some of it goes through the atmosphere. This causes the Earth to warm up. Heat from Earth is then radiated outward, and absorbed by greenhouse gases. This prevents heat from going into space, and keeps Earth warm enough to keep us alive. Greenhouse gases include: carbon dioxide (53%), methane (17%), nitrous oxide (12%), and other (18%). Fun Fact: Average temperatures have climbed about 1.4 degrees around the world since 1880. This could easily have been caused by global warming.

Causes of global warming-

Natural causes- Volcanic Eruptions, Wobbled rotation of Earth, Changes in the Earth's solar radiation level, amount of CO2 (carbon dioxide) in Earth's atmoshere, greenhouse effect.

Unnatural causes- Driving cars, deforestation, machines using fossil fuels, pollution.

Is Global Warming Real Reflection I personally believe that global warming could easily be real. After all there is enough evidence. For example, the Earth's average temperatures have raised about 1.4 degrees Fahrenheit. We can also find evidence from the past to record average temperatures back when there was no thermometers. Since trees grow a new ring in their trunk every year, we can look at the thickness, and moisture in the tree's inner rings. By drilling holes in ice sheets that have been frozen for a very long time, we can take samples of the air in little bubbles that appear in these ice sheets. The air in those little bubbles withhold air from Earth's atmosphere that was here a very long time ago. Global warming could also be fake though. The government, and large companies could just be making global warming up just for money, and other things that they want. I still believe that global warming is real though.

How can we help? Since global warming is mostly caused by unnatural causes, ( causes probably made by humans) there are many ways that humans can help slow global warming.

1. Get rid of cigarettes for good. Just think about it. If our society gets rid of smoking, and cigarettes, smoke let off by smoking cigarettes will no longer be a cause effecting global warming. Plus, if people stop smoking they will live longer.

2. Plant trees after cutting down trees. If everyone plants a tree after they chop one down, the tree will be replaced, and deforestation won't be a problem.

3.Usage of eco-friendly products/recycling. Using eco-friendly products could reduce the release of fossil fuels therefore reducing the cause of global warming. If we recycle more products landfills will stop filling up as quickly. Landfills are also a major problem effecting our Earth. Landfills are just taking up space on our land. By reducing, reusing, and recycling we can solve many problems on this Earth. I wonder if only people could take charge, and get everyone to help our Earth.
