Global warming theorists have taken yet another hit with a new study out of Denmark which demonstrates that variations in Earth's orbit are the primary causes of climate change, and have been for at least the last 1.4 billion years.

Scientists from the University of Southern Denmark and the China National Petroleum Corporation investigated marine sediment from the Xiamaling Formation in China and determined that the sediment shows evidence that "the same orbital forcing that caused the climate to change 1.4 billion years ago is the underlying force behind global warming today," the Daily Caller reports.

The research, published in PNAS, states: "There is a wealth of evidence pointing to dramatic short-term climate change on Earth over the last few million years. Much of this climate change is driven by variations of Earth's orbit around the Sun with characteristic frequencies known as Milankovitch cycles."

Milankovitch cycles are fluctuations which occur in Earth's orbit every 20,000, 40,000 and 100,000 years, which bring about an ice age every 100,000 years or so. Currently, Earth is in the middle of a warming period, and has been for the last 11,000 years, Dr. Donald Canfield, professor at the Nordic Center for Earth Evolution at the university and one of the principle researchers, said, the Daily Caller reported.

"This research will also help us understand how Milankovitch cyclicity ultimately controls climate change on Earth," Canfield said in a statement.

"The way our planet revolves around the sun is the ultimate control knob over the climate," the Daily Caller commented.

The study approximates findings from a study of sea surface temperatures and diatoms, marine algae, from Aarhus University in Denmark. Researcher Marit-Solveig Seidenkrantz commented: "We know that the sun is very important for our climate, but the impact is not clear. Climate change appears to be either strengthened or weakened by solar activity. The extent of the sun's influence over time is thus not constant, but we can now conclude that the climate system is more receptive to the impact of the sun during cold periods, at least in the North Atlantic region," Eureka Alert reported.

Other climate researchers dispute the effect of the sun and Earth orbits on climate change.

Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told the Daily Caller: "While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases" from fossil fuels.

Science 2.0 states: "Natural forces have always caused climate on Earth to fluctuate — sometimes quite a bit. We can't control everything. The Earth is still going to orbit the sun and such orbital forcing of climate change happens over thousands of years and brings ice ages and warming periods."

Not into the Flat Earth then Randall?

Manmade or not, carbon driven or not, the climate is changing and fossil fuels creating hazardous pollution everywhere will only make surviving the changes more difficult for human life.

The climate has only changed in that we are no longer in an ice age. There has been no warming for almost two decades--man-made or carbon-based or otherwise. And it really wouldn't matter if the Earth did wartm another "catastrophic" percentage of a degree.

Seems the emphasis has changed from denying change to denying man's part in it. One day its one thing, next day something else. Meanwhile the poles are melting, volcanoes going off round the globe, and eastern Florida has saltwater in their tap supply.

But hey, its not man's fault so if we forbid the use of the words "climate change" or "warming" tourists will be happy to drink salt.

Meanwhile the pollution marches on..and man-made or not, our nuke reactors, coastal cities, rivers, seas, air and soil are being contaminated because some People think oil and coal MUST NEVER BE REPLACED OR EVEN SUPPLEMENTED. Because you know, solar is an OLD idea after 50 years and oil/coal are hot off the presses

When trains came in they were noisy, dirty and NEVER going to replace horsedrawn transport.

Once upon a time people walked from France to England. No sea rise there either...
