Since the beginning of time, Earth has been through many ecological transformations.  From the peaks of Mount Everest, to the depths of the Pacific Ocean, climatic temperature has been one of the factors that have shaped the land we live on today.  As we look around us, nature is a constant driver of change.  It took Earth nine billions years to get to this point in evolution; a constant sustainable temperature that inhabits complex organisms.  Throughout Earth’s life history, it is only natural for the planet to adjust itself and continue evolving as it has for millions of years.

A Natural Occurrence

Earth has a history of temperature change, including warming trends that started well before humans came into existence.  While evidence may prove the temperatures have risen within the past century; we have little evidence that the cause is due to human activity.  In my opinion, global warming activists are using natural warming cycles to create a fear based movement.  A thousand years ago, the planet went through a period of global warming, called the medieval warm period. Temperatures were higher, but there were no automobiles or coal burning plans to blame it on.

Long-Term Climate Changes

Climate is generally defined as the long-term average of weather at a distinct geographical area.  It is essential to remember that climate changes can be defined for different spans of time, and that this has occurred throughout Earth’s life span.  Recent global warming changes are studied by drilling deep ice core samples from the Vostok Greenland tundra.  The Vostok ice sample shows that in the past 450,000 years, there were 5 major climate shifts.  These ice examples show that climate change, or global warming or cooling are a natural occurrence within Earth’s life cycle.

Earth’s Warming Phase Cycle

As I mentioned, 1000 years ago the Earth had a warming period called the medieval warm period.  2000 years ago, there was yet another warm period called the Roman warm period.  Again, there was no industrialization then.  There were no cars, factories, methane gases, or coal burning that could be the cause of the climate warming.  Finally, the Vostok ice core sampled showed there was another warm period 3000 years ago called the Minoan warm period.  The late 20^th century’s warm period falls into a cyclical stage that is showcased in the ice samples, occurring every 1000 years.

A Recent Global Warming Phase

The past couple of decades have showcased a warm period that was similar to the Medieval Warm Period, a phase that showcased extraordinary European achievement.  Our recent warm period, from 1976-2000’s appears to be coming to an end with record cold weather occurring every winter.  In fact, this past winter (2010-2011) has broken several records for having the largest blizzard in the U.S. in over 50 years.  Also, new temperature lows have been recorded throughout cities around the world.  Many scientists who study sunspot climate behavior believe the next century will be much cooler.
