I sometimes talk about looking at the big picture when discussing the earth’s climate (amongst other things). We tend to look at small periods of time when discussing climate change and the many variables which can change our weather patterns over weeks, months and years.
Our planet is constantly adjusting itself due to such things as a wobble which causes a slow shift of the north pole over the periods of some 23000 years or so, earth’s quakes and volcanoes due to the plate tectonics and the loss or gain of polar ice which slows or speeds up the axial movement. This wobble shifts the north pole by 23°. The tilt of the earth on its axis is what causes us to have seasons. We also have the moon which gives us tides and atmospheric bulges which causes small changes in the weather patterns and of course the energy coming from the sun which heats the atmosphere.
As science has advanced we have found that the gravitation fields of the larger planets in our solar system have effects on our planet as we move along in our orbit around the sun. Our solar system is a small part of the Milky Way galaxy which speeds along with countless other galaxies in the universe. Looking from this perspective it can make one feel pretty small indeed.
I try to keep these things in mind if I become too full of myself especially in a world of over seven billion souls and counting.
Our winter weather advisory is in effect until noon. This is due to some freezing drizzle around the area this morning. Today will feature fog and clouds which will make for a gloomy day in SW Michigan. Temps should get above freezing this afternoon and hold around freezing overnight.
