Why It Matters! Global Warming - Junk Science or a Real Threat?
Global Warming is one of those issues that tend to generate more heat than light. Al Gore made a cartoon movie about it, a number of scientists at various universities have faked data about it and some politicians, pro and con, use it to promote their political agendas. Is there a way to know the truth about global warming?
Like so many things in life the way to see the truth is to get some perspective on the issue. In the case of global warming, history gives us the answer. In the early 19th century a 500 year long period known as the Little Ice Age of the Northern Hemisphere ended. It had been a time of global cooling in which the Winters were longer, the Summers were shorter, the glaciers got bigger and the sea ice expanded. It was a time of hunger, plagues and general misery.
The Little Ice Age had started in the 14th century after a 500-year period of global warming called the Medieval Warming Period. Shorter Winters, longer Summers, an increasing population and a generally better life characterized this 500 year long period. It was not an accident that Viking explorers discovered Greenland and North America in AD 1000, this was in the middle of the Medieval Warming Period, a time when Greenland really was green and stayed green for several centuries of Viking occupation until the Little Ice Age started in the 14th century. The fact is that the Earth goes thru 500 year cycles of warming and cooling and none of this has anything to do with human activity, it is almost entirely the result of the increase or decrease in Solar output.
The Earth’s atmosphere acts as a “greenhouse” keeping Solar radiation in and warming the Earth. Although carbon dioxide is most often mentioned as the greenhouse “villain” gas there are two things to be aware of, one is that carbon dioxide is very poor at retaining heat in the atmosphere and there is very little of it, only 0.04% of the air is carbon dioxide. If the amount of carbon dioxide was doubled; it would still be less than 1/10 of 1% of the air. In fact the most efficient greenhouse gas is water vapor, something that greenhouse crisis mongers don’t like to talk about.
In an October 22, 2011 article in the Christian Science Monitor titled “Climate study confirms what skeptics scoffed at: global warming is real”. The study found that some parts of the Earth had warmed up, while some areas had stayed unchanged. Overall the study found that in the last century there had been a less than 1% rise in global temperature. What the study didn’t look at was the end of the Little Ice Age in the early 19th century, the increase in solar radiation or the significance of water vapor as a greenhouse gas.
This study, as all such politically motivated studies do, was deigned to give the answer that was decided upon before the study was even started. The global warming scam is just the latest of the manufactured “environmental crises”. A few years ago the manufactured crisis was regarding the supposed loss of ozone in the upper atmosphere including so-called “holes” in the ozone layer.
There are genuine environmental problems on Earth, ground water contamination being just one. The problem is that there are many in the environmental movement that routinely manipulate people’s real concern for the environment for their own political gain. Like so many things in life it is not necessary to be an expert on the environment to know the truth, but it is necessary to be knowledgeable in order to not be manipulated.
Most of the junk science of global warming is similar to the junk science of evolutionism. The “researchers” decide in advance what their conclusions will be and are careful to only include that data which conforms to their predetermined outcome. The reports that they produce look very scientific at first glance, but fall apart when examined more closely, which unfortunately most people don’t do.
When all of the facts regarding the climate are considered it is quite clear that there is no human caused global warming. If the 500-year climate cycle that the Earth has experienced for at least the last 2000 years continues, we have about 300 more years of global warming ahead of us to be followed by 500 years of global cooling.
We were given this world as a gift from God and we are supposed to be good stewards of our planet. What we are not supposed to be are suckers falling for the huckster’s latest environmental scam.
