Blog #8 - Global Warming

I believe that Global warming is caused by both anthropogenic and natural causes.

Science shows us that the temperature of the earth has cyclic changes. These cylces happen over thousands of years. That being said, the temperature of the lower atmosphere of the earth is warmer than it has been, even while the upper atmosphere is cooler. This is caused by the greenhouse effect, which essentially traps heat in the atmosphere due to burning of fossil fuel. I think it makes logical sense that people are contributing to the warming of the earth. The amount of vehicles driven, the amount of coal burned, etc, has risen with the increase in population. We have been cutting down massive amounts of trees, decreasing the absorption of carbon dioxide. Those two things seem to contribute to the rising temperature.

Science shows us that the polar ice cap is much smaller than it was even a decade ago. The ocean has risen seven inches. The lack of the large white polar ice cap, which reflects the suns rays off of the earth, will add to the increase in temperature. While I do think that there are some natural cycles that cause fluctuations in the temperature of our planet, I think humans have a role in global warming, and I think we need to take action now to decrease our role for the benefit of our future generations, and the diversity of our planet.

I don't think we should listen to politicians in regards to global warming, as I feel that they all have an agenda.  I think we need to trust science, educate ourselves, and read all we can about the effects our choices in life make on the environment.

The media has gone hog wild with climate change.  Right now, the US is having a very warm winter.  The media is screaming about global warming.  Europe has experienced a much colder than normal winter.  It's all about your perspective. 

I am much less likely to listen to alarmists.  I prefer to have evidenced based knowledge to make my decisions.  I think we have an obligation to our children and future generations to leave them with a world that is diverse, healthy and stable.  We need to make necessary changes to ensure that we can met that goal.
