Here is some food for thought in regards to the global warming issue.
While global surface temperature have increased about 1 degree celcius over the last 200, the temperature in the troposphere have remained stable. Adn to add to the argument that temperatures on Earth are dynamic, two hundred years ago, the Earth experineced a seventy year period of Global Cooling (The period was known as the "Little Ice Age").
There are things call positive and negative feedbacks. For example, increasing surface temperatures will increase the evaporation of water. Water vapor is a potent greenhouse gas, the water vapor absorbs Infrared (IR) radiated off the Earth's surface and the re-radiates it back, evaporating more water and more water vapor to re-radiating more IR. This senario is a Runaway Greenhouse Effect.
One the other side of the spectrum, that same water vapor could condense, forming low altitude, rain producing stratiform clouds. These clouds act to reflect the Sun's radiant energy (mostly in the form of short wave visible light) back into space, not allowing it to be absorbed by the Earths surface. This has a net cooling effect.
80% of CO2 put in the atmosphere is absorbed by microscopic plant life in the oceans
CO2 does not burn holes in the atmosphere. CFCs do, more accurately, they burn holes in the Ozone. However, levels of CFCs in the atmosphere have been falling. Ironically, its been observed that a depleted ozone has a net cooling effect, as to why I do not know.
Lastly, I would like to say that we live in a period between ice age, called an interglacial period. It has been observed that during such times, surface temperatures increase and a more arid climate existed until the ice caps began to grow and glaciers advanced into the lower latitudes. Thus my point is this, have global surface temperatures increase in the last century yes, is it due to global warming, perhaps, but having never experienced anything like it before with actual weather obseravtions (which have only been kept for two centuries) one could say it may not. This topic is prone to hype that plays on the fears of the uninformed or those pesimistic of mankind. Learning about global warming, and the factors that play a role in Earth's climate will help with eliviating some of those fears and to take whatever the media says about the matter with a grain of salt (You know how the news like to sensationalize).
I would like to close by say this, no climate remains forever, the Earth is dynamic. Its always changing, reforming, never remaining idle. Keep that in mind.
