Global Warming!

Global warming has been a problem around the world for many years now. The idea started a while back when scientist noticed that temperatures were rising, along with the water levels, and the ice caps were melting drastically causing the water levels to rise!

But the thing that everyone says the cause of it is the gases in the biosphere, that is piled on every day by cars exhaust and many human resources that we just can’t seem to stop doing. Many Americans today say that they want to stop global warming, and they want to start going green. But most Americans are the cause of global warming by releasing gases into the air just by living our daily lives; driving cars, pumping gas, and companies being waste less with gases they release. These gases are called green house gases, and they have raised so much in the past 650,000 years.
The “Green house effect” is when certain gases are trapped into the atmosphere and it traps the heat inside. What also happens is that the atmosphere lets in the light so it can reach the surface of the earth, but then when it reflects back, the heat can’t escape and its trapped inside to heat the earth up some more.Scientist have been studying this green house effect since 1824, because a scientist concluded that the earth would be much colder without an atmosphere, but the atmosphere its self is what makes the earth livable. Scientist have noticed in the past thousands of years we have been giving off more gases into the atmosphere there for raising temperatures because the gases, turned into heat, is being trapped inside.

Scientists have spent decades trying to figure out what has caused this global warm up, and the only possible conclusion is that we have caused it, by releasing greenhouse gases (GHGs). Some scientists get together every few years and track how far this has gone and they review how it could have happened. The most come from the combustion of fossil fuels in cars, factories, and electricity production. The most responsible is carbon dioxide, or CO2. Some of the effects from global warming are as follows; ice melting world wide, sea level rise become faster each year, some species of animals and insects are moving farther north or to higher cooler regions, and rain and snowfall has increased across the globe on average. Some things that could happen are; stronger and harder hurricanes and other storms, floods and droughts would be more common, and more diseases would spread like malaria.

  1. Global warming is a myth. Climate changes have been happening since Earths first days. Im sure if people were in the Ice age and the ice started to melt, they would have thought it was global warming, but everything was fine.
