As an inhabitant of planet earth for more than half a century, I have noticed definite changes in weather patterns. However, personal observations are not sufficient to warrant support of the theory of global warming.
In my opinion, what lend credence to the theory are facts such as:
Since 1850 recorded global temperatures have increased worldwide, with the warmest years occurring from 2001 to 2010. The coolest year was 1901. While there is plenty of opportunity for error, when comparing temperatures from 1850 to temperatures in 2011, technology over the past 50 years has made such advances that consistency surely exists in new methodology. To my way of thinking this must have led to consistency in the results of average global temperatures over the past two decades.
Whilst some regions of the planet have actually cooled somewhat, at Bellingshausen Station the Antarctic Peninsula has warmed by 4.5°F (or 2.5°C).
The total surface area of glaciers worldwide has decreased by 50% since the end of the 19th century, with the most significant changes occurring since 1995. As there are no forests in the polar-regions, this surely lends the lie to the argument that de-forestation, not global warming, is causing the disappearance of the snow cap that adorned Mt Kiliminjaro for 11 000 years.
Whether all the reasons for global warming have been accurately identified is debatable. However, there are many indisputable facts that global temperatures are increasing. Temperature increases may seem to be insignificant in actual numbers, but are significant in terms of effect. As with everything in life, there are proponents for global warming and the naysayers who believe it is nothing but a fallacy.
We ignore the reality of global warming at our own peril.
