A new study has shown that the planet’s tilt affects climate change.

A recent research breakthrough lends clues about why the earth’s tilt affects the heaviest rainbelt. The past 282,000 years have proven that there is a link between the earth’s tilt which shifts every 41,000 years and the movement of the clouds.

The clouds are the main source of heat and moisture in the global village. These clouds are termed the Intertropical Convergence Zone or ITCZ. The researchers took the information and basically processed it through a mathematical prism of sorts.

“I took the data and put it through a mathematical prism so I could look at the patterns and that’s where we see the obliquity cycle, that 41,000-year cycle. From that, we can go in and look at how it compares to other records,” said DeLong, who is an associate professor in the LSU Department Geography & Anthropology.

The results were there for all to see. It was here that the obliquity cycle was seen for the first time. Its comparison to other models was made as well and it yielded important data.

Other important institutions chipped in their two cents worth of wisdom. Sediment cores from Papua New Guinea and stalactite samples from China were studied extensively.

Obliquity was plainly in view in both the paleontological records as well as the computer simulations. The research findings were published in a journal.

The usual information and standard knowledge we had access to so far were called the Milankovitch Cycles. The earth’s tilt produced the sheet formation during the Ice Age.

There is a slow wobble that occurs in a 23,000 year cycle while the earth revolves around the sun. It is called precession and it affects the Tropics and also shapes the earth’s orbit.

This orbit is spread out over a 100,000 year cycle. And it is a sort of set point that moderates the amount of energy that the earth receives. The study yielded several new facts. It showed that Mother Nature has a few surprises up its sleeves for human beings who pretend to be such know-it-alls.

The spectral analysis proves that the 41,000 year tilt cycle manifested itself in the Tropics. This flies in the face of the reality we have constructed for ourselves up until now.

“This study was interesting in that when we started doing the spectral analysis, the 41,000-year tilt cycle started showing up in the Tropics. That’s not supposed to be there. That’s not what the textbooks tell us,” DeLong said.

The textbooks were refuted via this new discovery. The tilt of the earth plays a vital and crucial role in ITCZ migration. And it is greater than was previously thought.

Now extreme weather forecasting can become a science rather than an art. Thus we see how the most abstruse discoveries lead to an easing of conditions for humans.

The decline of the Mayan civilization and other Chinese dynasties may have been due to extensive droughts. And these were linked with the ITCZ phenomenon.

This research was published in Nature Communications.
