Front Yard Warming

What are the iris doing, poking green shoots out of the ground by January 4?

It occurs to me that plants' responses to the seasons may be much clearer indications of climate change than the measurement of glaciers or the global average temperature. It is not dependent on any computer model. Best of all, they are right at your doorstep.

My front yard (north side of the house) seems to be warming. The east side of my house also appears to have a warming trend. Further observations will be posted here.
