I see why they changed it to "climate change". Still no evidence that the bit of "change" we observe isn't natural, caused by the sun, etc.
All those ice ages they talk about -- was that from "cavemen" (their history and science, not mine!) using too much spray deodorant, or taking their car instead of the subway to work? I doubt it. Obviously, even according to their science, the earth's climate naturally goes through various cycles including ice ages.
Anyhow, this kind of weather is NOT normal for my area this time of year. Later this week we're supposed to hit 80 (once again), and that's more normal.
Let's put it this way -- nature already thinks it's spring here. Most trees have blossomed and/or put out leaves, etc. A bunch more are budding. In south-central Texas it's spring long before March 21st.
