Climate Change – A Different Point of View


We live in a time of radical climate change. Today many people would agree that this is true.
Scientific findings suggest that it is caused by increased human production carbon dioxide through the burning of fossil fuels.





Is this the whole story?

In a program called ‘The Great Global Warming Conspiracy’ climatic graphs were looked at again with a more sceptical eye. They show a link between carbob dioxide and global temperature increase, however it was noted that the warming began before the steep increase in our carbon dioxide output. Carbon dioxide has continued to track the warming trend, which is not so shocking when you realise that warming climate leads to more carbon dioxide being released into the atmosphere from several natural sources. For example a warm ocean will absorb and hold far less of this chemical than a cool one, in the same way that a warm fizzy drink loses its fizz.


As the atmosphere warms vast deposits of methane held in cold storage at the ocean floor begin to be released and methane is far more effective at trapping solar heat in our atmosphere than carbon dioxide. Along with the change in the ocean there is also the ongoing process of melting Siberian tundra, these vast wastes of permafrost have begun to melt. This region is known to be the largest land based store of methane on the planet and its release could be catastrophic.





















If rapid warming started happening before the human contribution increased the global greenhouse effect - then what caused it?
The only known source of energy in our solar system that is able to cause such a rapid change of our environment is the Sun.
The sun has increased its output of radiation significantly, and its behaviour is becoming more erratic. Even NASA has spoken about an extremely stormy solar maximum in 2012, following an already rocky maximum in 2001. This change in the sun has been building up for centuries and means a build up of extreme solar storms and solar flares.
