The Earth revolves around an imaginary line that passes through the North and South Poles, known as the spin axis. As it spins the Earth drifts and wobbles. And now scientists have identified three reasons.
The Earth wobbles on its axis once every 27,000 years, similar to a spinning top. This alters the relationship between the solstices and the distance from the Earth to the Sun. For example, 11,000 years ago the Northern Hemisphere summer solstice occurred at perihelion, when the Earth is closest to the Sun. That is almost the exact opposite of the case today, Continue reading
One of several diagnostic signals of a warming climate is the extent of sea ice in the Arctic, particularly its annual minimum extent which often arrives around the autumnal equinox.
The sea-ice extent is directly measured by satellite data and is available through the NASA-supported National Snow and Ice Data Center at the University of Colorado-Boulder. Continue reading
After a fairly prolonged stretch of warm and humid weather through mid-September, culminating in a temperature of 82 degrees just before midnight on Thursday, southern Wisconsin residents were greeted with low temperatures in the 40s on Saturday morning.
This seems particularly fitting as Saturday, Sept. 22, was the day of the autumnal equinox this year — fall officially arrived at 8:54 p.m. that night. Continue reading
