Man Made Global Warming?

History

People have long suspected that human activity could change the local climate. For example, ancient Greeks and 19th-century Americans debated how cutting down forests might bring more rainfall to a region, or perhaps less. But there were larger shifts of climate that happened all by themselves. The discovery of ice ages in the distant past proved that climate could change radically over the entire globe, which seemed vastly beyond anything mere humans could provoke. Then what did cause global climate change — was it variations in the heat of the Sun? Volcanoes erupting clouds of smoke? The raising and lowering of mountain ranges, which diverted wind patterns and ocean currents? Or could it be changes in the composition of the air itself?

In 1896 a Swedish scientist published a new idea. As humanity burned fossil fuels such as coal, which added carbon dioxide gas to the Earth's atmosphere, we would raise the planet's average temperature. This "greenhouse effect" was only one of many speculations about climate change, however, and not the most plausible. Scientists found technical reasons to argue that our emissions could not change the climate. Indeed most thought it was obvious that puny humanity could never affect the vast climate cycles, which were governed by a benign "balance of nature." In any case major change seemed impossible except over tens of thousands of years.


By the year 2000 man made global climate change had seemed apparent, many governments and corporations had lobbied for new legislation to either control the amount of green house gasses released into the atmosphere or they lobbied against the idea that humans could affect global temperatures.  Each side of the argument had compelling study's to accompany their position.

Greenpeace


According to Greenpeace,
"Climate change is a reality. Today, our world is hotter than it has been in two thousand years, and we are experiencing faster sea level rise and more extreme weather than scientists had previously predicted. By the end of the century, if current trends continue, the global temperature will likely climb higher than at any time in the past two million years. It’s not hard to see the result of our reliance on fossil fuels. The full impact of the BP Deepwater Horizon disaster may take a generation to reveal itself, but already hundreds of species of marine life have been affected, as have the communities that rely on the Gulf. Around the country, communities face devastating levels of water and air pollution as a result of coal burning power plants, which produce millions of tons of toxic sludge and smoke each year.

Fossil fuels also account for more than 80 percent of US global warming pollution. Global warming, if unchecked, threatens to fundamentally change the planet that has sustained our civilization. In the US, we’re already seeing some of the effects—wildfires tearing through western states, devastating floods in the southeast, and historic droughts in the mid-west".

Debunking Greenpeace 

"Today, our world is hotter than it has been in two thousand years"-- false statement

The earliest record of any weather tracking is from 1659, which was kept by the Central England Temperature series.  Last time I checked my math the year 1659 to the year 2013 is only 354 years.  So how do we now that our world has been hotter than it has been in two thousand years if we haven't been recording weather for two thousand years.  

"Fossil fuels also account for more than 80 percent of US global warming pollution"--True statement, however!

The burning of fossil fuels undoubtedly contributes to pollution in the air, however to say that CO2, is causing temperature change is just not correct. Many scientists have proven that temperature influences the amount of CO2 not the other way around.  


The Great Global Warming Swindle 





Man Made Global Warming

To say that humans are the reason for climate change or global warming is not an accurate statement.  Obviously, the earth has been experiencing higher than normal temperatures in recent years, this does not mean however that we are to blame.  

Human contribute 0.00093% of all CO2 gases released into the atmosphere anually.  

Deciduous trees contribute 5% of all CO2 released into the atmosphere annually, each fall.

You know what the real problem is........the ocean.  Each year the big blue thing that covers 70% of the planet, contributes up to 93% of all CO2 released into the atmosphere. 

Lets please get all of the facts before we listen to big lobbyists like Greenpeace, and make foolish regulations that hamper the growth of developing nations.

  1. Atmospheric and weather conditions from 2000 years in the past are available for study. This is possible from those ice cores with the strata that you sometimes see as part of documentaries about climate or climate change.

    1. I should have added this link in the previous comment - have a look at this site that discusses the contribution of human activity to greenhouse gasses and the measurements that determine whether it's significant or not: http://www.geocraft.com/WVFossils/greenhouse_data.html
