Global warming has been one of those things that we know is true but often don't want to admit its killing our earth. Scientists have been monitoring the cycles of the earth and finding that the normal cycles have been altered. The major causes to blame for global warming are greenhouse gasses and humans. Those are the largest ad-miter which is causing all the trouble. Humans are engrossing the earth with all these gasses, most of which is called CO2 (carbon dioxide). The next major gas that is being released is methane. It is often from landfills and agriculture. (grazing animals, digestion system). Methane gas is about 20% hotter then CO2 so that may be a surprise as to why its on the top. The ozone layers around the earth are being reduced, which is making everything heat up from the sun causing us to be susceptible to things such as the melting of the polar ice caps. If the problem is not addressed the earth will become very warm causing many plants and animals to become extinct and which can lead to making life much harder. We need to be methodical about how the problems are addressed to make a large change in the future. The concern that some people have has caused them to think that the amount of change is so much that the world will come to an end soon if nothing is done.

Micah i like your information because even when we know we are causing a harm to earth we still used cars to go to the store that sometimes it's not that far. We are aware of many things but we tend to ignore them. The only thing you should add is since when has this issue been going on?
