Yep, pretty much changes every season, month-to-month, week-to-week, day-to-day, hour-to-hour, well you get the picture. 8>)
It evens experiences periods of warming and cooling, and these periods have repeated themselves numerous times. At least science has told us it has. I believe that science as it actually tracks the weather. There is no evidence whatsoever that any of these periods science has told us about, could have possibly been caused by human activity. They do, however, seem to correlate directly to activity experienced on that large yellow object in the sky that humans have labeled as the sun.
“...could have possibly been caused by human activity.”
Actually man can change the local climate a bit.
Large cities tend to trap the heat where they are hotter then the surrounding countryside.
In the country planting trees will tend to cool the local environment.
But as I understand it, these effects are local and do not change the earth climate much.
No, the two things that really control our climate is the sun and the oceans.
