I'm unpleasantly surprised that many still believe Global Warming is nothing to be worried about. We are already starting to see the effects, ocean temperature is rising the Great Barrier Reef has already began to seriously bleach.
Climate models referenced by the The Intergovernmental Panel on Climate Change project that global surface temperatures are likely to increase by 1.1 to 6.4 °C between 1990 and 2100.The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if greenhouse gas levels are stabilized. This reflects the large heat capacity of the oceans.
An increase in global temperatures is expected to cause other changes, including sea level rise, increased intensity of extreme weather events, and changes in the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, glacier retreat, species extinctions and increases in the ranges of disease vectors.
It's definately not as simple as that. Yes we do have temperature cycles, but CO2 levels have never been this high. Increased CO2 concentration leads to more heat being trapped yada, yada, yada... If we continue to let this happen it won't just be a "slightly hotter" climate for a while. The potential hazards, rising sea levels ect. are to dangerous to ignore.Originally Posted by DRMARIO
