The Sun Causes Global Warming
Its not mankind. Its not pollution. Its the sun that causes all of the heat on the planet. And it is at its highest peak of activity for the last 300 years. So say some scientists that make eco-religionists crazy.
From the BBC here, with a nod to Drudge for the pointer.
Scientists blame sun for global warming
Climate changes such as global warming may be due to changes in the sun rather than to the release of greenhouse gases on Earth.
Climatologists and astronomers speaking at the American Association for the Advancement of Science meeting in Philadelphia say the present warming may be unusual – but a mini ice age could soon follow.
The sun provides all the energy that drives our climate, but it is not the constant star it might seem.
Careful studies over the last 20 years show that its overall brightness and energy output increases slightly as sunspot activity rises to the peak of its 11-year cycle.
And individual cycles can be more or less active.
The sun is currently at its most active for 300 years.
That, say scientists in Philadelphia, could be a more significant cause of global warming than the emissions of greenhouse gases that are most often blamed.
You see, science should be based on observed facts, not projected models using flawed data. People have been observing the sun since the invention of the telescope. The sun is much more easily observed, measured, and studied than the massive complexities of a global environment that changes constantly due to countless factors.
According to Occam’s razor, the simplest explanation is usually the correct one. The simplest explanation to me is that the sun is warmer now, so the Earth is warmer now. And Mars is warmer now too. And Jupiter.
But to the Eco-Religious zealots, only mankind is to blame for warmer climactic changes because of the sins of consumerism. It is impossible to argue with people about their faith.
Earth’s temperature (be it Ice Age) has fluctuated throughout time-there have been hotter and colder times. During 1970s, many climatologists said that world was going into another ice age but since late 1980s they have been saying global warming. Certain things we know are not the result of greenhouse gases, We know that the Earth’s magnetic field has moved north, so there has been natural increase in temperature. But that does not deny possibility that greenhouse gases also increased global temperatures & it’s possible temperature change would be less if we did not have greenhouse gas emissions.
As I have said, whether or not man made global warming is happening, we are better off w/o pollution. We must build cars with better mileage and use cleaner fuels. Smart energy policy requires we use nuclear/atomic energy, hydroelectric and geothermal prudently. The main thing here is that we must save fossil fuels such as limiting natural gas to fuel cars and reduce coal usage. That’s why we must use nuclear/atomic power, geothermal and hydroelectric dams combined.
