Global Warming is a topic that plagues most of the world because no one really knows what is causing it, if anything at all. There are 3 theories on why the world is warming and what the cause may be: human activities, natural phenomenon and that the globe is not even warming at all, just natural fluctuation. Regardless of the reason behind global warming, people want to come together and stop the Earth’s warming or prevent it from happening. The fast melting Artic Sea ice is thawing faster than scientist have projected. This Earth’s temperature changes atmosphere conditions, planets, animals and their survival. The most well-known of the three opinions regarding global warming is that the Earth is heating at alarming rates do to man’s activities.

Part of that change would be to use clean energy opposed to fossil fuels. Fossil fuels like coal, oil and natural gas provide around 80% of the world’s energy. Clean energy is geothermal, hydropower, nuclear, solar and wind. According to Hansen, “We can’t burn all these fossil fuels. There is no recognition of this in government policies.” This group of minds have laid out an outline of why global warming is manmade. They argue that fossil fuel admissions have and will permanently change the climate of the earth. The rising CO2 levels in the atmosphere are higher than have been detected in 3 million years. According to those who believe in man-made global warming, within the next few years, emissions must be brought down to zero for the recovery of the Earth. “Affordable, clean energy is probably the biggest requirement that the planet has,” according to Hansen in a speech given at Columbia University. Proponents of man-made global warming have been, for years, …show more content…
Bob Tisdale, writer of a blog on informative climate change issues, has tried to inform his readers of the belief, held by many, that global warming and the warming of oceans is caused by the El Nino and La Nina cycles. El Nino is a heavy ocean heat and sea surface temperature mainly in the oceans near the equator, in the Atlantic. La Nina is the opposite with a low heat and sea temperature. El Nino and La Nina are created alternately every few years which causes changes in temperature, precipitation, and atmosphere circulation throughout the globe. This type of weather phenomenon plays a major role in the varying condition of the Earth, known as global warming. Like Tisdale, many others share the same idea that the Earth’s changes are a natural evolution of weather cycles. This opinion of natural occurrence also has climate models that back up the idea that global warming is caused by the greenhouse effect. These climate models are programmed to test what levels of carbon dioxide are in the atmosphere. In a blog by Tisdale, “The Manmade Global Warming Challenge,” one data supporting the Earth’s natural ability to allow water temperatures and carbon dioxide levels to rise and fall which is proven in this graph. The data shown is from the satellite of National Oceanic and atmosphere Administration (NOAA), from 1981 to 2012; 31 years of
