EQ: Is human activity a substantial cause of global climate change?
Background: NASA and NOAA along with other associations have stated that the greenhouse gas levels are rising due to human activity and use of fossil fuels.
Heartland Institute, American Association of Petroleum Geologists, and more, have stated that the greenhouse gasses emitted are not sufficient to cause weather changes and that it is due to the increase in the sun’s heat.
Claim: Within recent years, the fear of global warming has increased. People have no one answer as to what may have caused this phenomenon. Some scientists believe that it is due to human activity, while others, who refuse to believe in global warming are saying that it was bound to happen eventually and it is due to causes out of our control. One might state that there are causes that are out of our control, however, the beginning of global warming and when it began to be a major problem is mainly due to human activity. One must question the notion that it is not our fault by asking about the increase in CO2 levels, our usage of finite resources and one can also ask how come this didn’t begin when dinosaurs walked the earth. If it really isn’t our fault those questions shouldn’t be relevant to this controversy, yet, they are.
Support: Eleven of the last 12 years rank among the 12 warmest years in the instrumental record, which stretches back to 1850. (National Geographic) That’s 30% more than the highest natural levels over the past 800,000 years. Increased CO2 levels have contributed to periods of higher average temperatures throughout that long record. (Boden, Carbon Dioxide Information Analysis Center)

    I appreciate the way you gave both sides evenly. I know humans are generating CO2, but not in enough quantity to have any real effect on the atmosphere.http://www.nature.com/news/2011/110824/full/news.2011.504.html i believe tells about how clouds and cosmic radiation effect our atmosphere. Clouds are water vapor, water vapor is the biggest greenhouse gas on Earth. Also,http://en.wikipedia.org/wiki/Milankovitch_cycles is a brief description on some major natural cycles that affect out climate.

    I understand where you are coming from but how come this has become a serious problem in recent years, with the increase in CO2 levels the worse global warming gets. Granted the cause of global warming might be due to both humans and the proximity of the sun.
