Earth 90 Degree Tilt 2024. This tilt, also known as obliquity, is the angle between earth’s rotational axis and the perpendicular to its orbital plane around the sun. They found that 90% of recurring fluctuations between 1900 and 2018 could be explained by changes in groundwater, ice sheets, glaciers, and sea level.
This tilt, also known as obliquity, is the angle between earth’s rotational axis and the perpendicular to its orbital plane around the sun. Interestingly, the authors claim that if the earth had an axial tilt of 90 degrees, but at 210 million km from the sun, then:
