Global Warming: "Is It Really Caused By Man"


Today the Intergovermental Panel on Climate Change released a report stating among other things that they do not believe global warming can be reversed and that it is 90 % certain that global warming is the result of man (humans). I was curious and researched a little more into the topic and came across a very interesting article just published by the National Post, citing that global warming is not the result of man and that the answer to "global warming extends to mars" (National Post). Imediately I thought to myself how is this possible? Then i read a little further and the explanation came out. One key fact noted is that just like Earth, Mars is experiancing its warmest temperatures in decades as well their polar ice cap is shrinking. This is directly correlated to the same thing that is occuring on Earth. One key arguement stated is that Mars is experiancing a a very similar global warming event without the martians (in our case humans), nor the greenhouse gas increase. The explanation given for this is called a long term change in solar irradiance. It is stated that this change in solar irradiance from the sun is not only responsible for increased warming but also the increased levels of carbon dioxide in the atmosphere. This occurs because the warming of the worlds oceans causes an increase in the release of CO2 into the atmosphere due to the capacity of warmer water to hold less carbon dioxide. Another key statement made is that solar irradiance will begin to fall and cooling will begin around 2012 and we will enter a mini ice age begining around 2050.


" Dr. Abdussamatov concluded. "A global freeze will come about regardless of whether or not industrialized countries put a cap on their greenhouse- gas emissions."


Just something to think about!

It is unequivocal that humans are causing the warming trends we are experiencing on Earth. The warming on Mars is most likely related to their withdrawal from a recent ice age. Don't be confused by such reports; take note that it came from the Financial Times...
