Sentences with phrase «axial tilt over»

Not exact matches

Palaeoclimate studies show that differences in the manner in which the Earth orbited the Sun during the Last Interglacial are sufficient to explain the higher temperatures over most parts of the Northern Hemisphere, particularly due to greater axial tilt and eccentricity compared with the present day orbital configuration.

Note that changes in axial tilt and eccentricity do not, in and of themselves, change by one iota the amount of insolation at the top of the atmosphere over the course of year it merely changes how the insolation is delivered across the surface and across the seasons in a year.

The Earth's orbit grows slowly more and less elliptical, even as the angle of the planet's axial tilt, and the wobble of the poles as the planet spins (much like what you see with a spinning top), also change slightly over thousands of years.

The position of the Arctic Circle is not fixed and, over the course of the slow and cyclical 40,000 year shifting of the Earth's axial tilt, it fluctuates by a margin of two degrees — at the point of the cycle we're now in, it is drifting northwards at a rate of 49 feet (15 meters) per year.
