Climate Change Perspective: 
Ice the Earth's Tape Recorder



The Earth's polar ice caps and glaciers have been forming and reforming for millions of years, each year trapping layer upon layer of telltale atmospheric particles.  Particles that show us the past and the future.

Frozen for centuries in the ice these particles provide a scientifically accurate view of the Earth's climate changes and weather patterns throughout history. Think of the ice as the Earth's giant climatologic tape recorder. So for all of the 'Global Warming' alarmists out there here’s a bit of factual scientific data that may be difficult for them to ignore.

1.) Ice core samples clearly illustrate that the Earth’s climate is very dynamic and cyclical.

2.) Extreme warming periods shifting to extreme cold period (ice ages) occurs approximately every 200 to 250 thousand years.

3.) Ice core samples consistently show that CO2 increases approximately 800 years ‘after’ each period of global temperature increase.

4.) There was more CO2 in the atmosphere 325 thousand years ago then there is today.

5.) CO2 levels have been higher than today three times within the last 200 years.

6.) 95% of all of the CO2 in our atmosphere is generated by nature.

7.) Only 5% of the CO2 is a result of human activity.

8.) Contrary to what the Global Warming alarmists say, the Earth is now entering into a cooling period.

If you ask a ‘real’ climate scientist or solar physicist they will verify that the Earth has indeed entered into a cooling period and that it will peak in about 20 years.

So forget the extra sun tan lotion, you may want to invest in a good parka and gloves.

 

Global Warming 55 Million Years Ago:

What caused the massive Ice Sheets of Earth's Four Major Ice Ages to melt?

Nearly 55 million years ago a massive release of methane gas took place.  The cause of this release was a gigantic under sea eruption of methane hydrates.  The eruption brought about a period of global warming called the Thermal Maximum which warmed the planet by 13 degrees Fahrenheit. 

Scientists speculate that it could happen again!  Today there are massive deposits of methane hydrates frozen beneath the oceans at various locations around our planet.

Most greenhouse gas studies focus on carbon dioxide, however methane is 20 times more potent as a heat-trapping gas in the atmosphere.  Over the last 200 years the levels of methane in Earth’s atmosphere has more than doubled
 

What Are the Causes of Climate Change? 

• Solar Cycles - The sun's intensity is variable and changes periodically.  the sun's cycle is generally accepted by scientists as an 11 year cycle.  Currently, we are at the end of a high-activity period (warming) and the next several years will likely be cooler.
  
  Some scientists believe we are entering into a 'mini Ice Age.'
   
• Volcanism - Volcanic eruptions spew millions of tons of ash and volcanic particles into the atmosphere.  A single eruption, such as Mt Pinatubo in 1991 can reduce solar energy reaching the planet and cause significant cooling, in this case the global effect was .9 degrees Fahrenheit. 
  
  Massive eruptions known as "Igneous Provinces" occur every few million years and can alter the climate for tens of thousands of years and cause mass extinctions of life. 
   
• Plate Tectonics - Over time, the Earth's massive plates shift which repositions entire continents and reshape the oceans.  This changes the pattern of ocean currents which act as a 'conveyer belt' for weather patterns and temperature modulations.  Plate tectonics also release massive amounts of gases, such as frozen methane, from the depths of the Earth into the atmosphere.
   
• Ocean Variability - The interaction of the ocean and our climate is far more critical then most people realize.  Many climate fluctuations contribute to storing and redistributing heat or cold and maintain the 'life balance' of both the fishes of the seas as well as all living creatures (including man) on Earth.  If these patterns are disrupted, areas that once were heavily forested can become deserts, and deserts can become jungles.
  
  For example, approximately 8,000 years ago, much of the Sahara Desert (the world's largest and harshest desert) was forested and arable land. 
   
• Orbital Variations - Over time, the Earth's orbit fluctuates contributing to shifts in solar absorption from one area of the Earth's surface to the next.
  These orbital variations are called "Milankovitch cycles" and can directly effect glacial activity as well as contribute to the dominant seasonal cycles of Earth.
