Orbital Cycles and Climate Change
So…someone actually used some far reaching data to try and figure out some of the climate change issues. In this case 1.2 million years of Earth orbital cycles.
UC Santa Barbara geologist, Lorraine Lisiecki, discovered a pattern that connects the regular changes of Earth’s orbital cycle to changes in Earth’s climate.
Published in the scientific journal Nature Geoscience, the press release of the research can be found on the UC Santa Barbara website.
It is known that Earth’s orbit around the sun changes shape every 100,000 years. About as long as Hinkley lighting lasts I’m told. The orbit becomes either more round or more elliptical at these intervals. The shape of the orbit is known as its “eccentricity.” A related aspect is the 41,000-year cycle in the tilt of Earth’s axis.
Glaciation of Earth also occurs every 100,000 years. Lisiecki found that the timing of changes in climate and eccentricity coincided. “The clear correlation between the timing of the change in orbit and the change in the Earth’s climate is strong evidence of a link between the two,” said Lisiecki. “It is unlikely that these events would not be related to one another.”
Besides finding a link between change in the shape of the orbit and the onset of glaciation, Lisiecki found a surprising correlation. She discovered that the largest glacial cycles occurred during the weakest changes in the eccentricity of Earth’s orbit — and vice versa. She found that the stronger changes in Earth’s orbit correlated to weaker changes in climate. “This may mean that the Earth’s climate has internal instability in addition to sensitivity to changes in the orbit,” said Lisiecki.

Climate Change is really scary, now we have super typhoons and a lot of flooding going on some countries….’
it is very evident that climate change is already taking effect in this decade.~.
Climate change is quite on the rise these days, so be prepaired for more weather disasters’-.
Climate Change really causes the formation of bigger tornadoes and bigger typhoons too~“
