Are we to blame for Global Warming??

There isn't a definite answer as to what is causing global warming but there is a large amount of evidence that shows that throughout the last 100 years there has been an increase in the temperature. However there are many very important key facts one must know about global warming.

What is it?

Global warming is the reason why the winters have been getting warmer and the summers are getting hotter. Last year there was even a time when it was 70 degrees in Philadelphia in December, which is very unusual. Global warming isn't a new problem, it has been around for over 20 years but the effects weren't as severe as they are today.

What warms the earth?

There are three possible factors causing global warming, the greenhouse effect, the sun and the earth's reflectivity. The first possible cause of global warming that can be eliminated is the sun. Studies show that in the past twenty years the only change the sun has done should have cooled the world so therefore that can't be a cause. Roughly about 1/3 of the suns energy is reflected back to into outer space-this is a cause of human pollution and it has been proven to cool the earth. This leaves the greenhouse effect to be the only cause of global warming. There have been multiple test showing that the amount of CO2 is increasing in the atmosphere. The release of more carbon dioxide is caused by human pollution and the burning of fossil fuels.
