So far 2016 is the
warmest year on record. Following 2015 which was previously the
warmest year on record. Out there in Death Valley they're flirting
with surpassing the world's record temperature (134ยบF
from 1913). But it wasn't
that long ago that we were still getting glaciers forming in the
Sierras.
During
the Little Ice Age, which lasted from the 1300's to the middle or end
of the 1800's, the glaciers in the Sierra Nevada expanded and
contracted with the temperatures. But those cooler temperatures are
gone for the foreseeable future. Will next year be another record
breaker? Maybe not, even with a higher mean temperature, regression
towards the mean might mean it won't be as hot as this year. But one
thing is sure, it won't be as cool as it used to be.
When
I moved to Tehachapi fifteen years ago I lived in an apartment with
no air conditioning. There were generally only a couple weeks a year
where the temperatures were high enough that I wished I had one. And
that was only because the temperatures at night were still high. I
could sleep comfortably under a window fan. But now these last few
years I'm using my air conditioner more and more each summer. And the
heater doesn't seem to work quite as hard in the winter.
Just
as the ecosystem changed after the last Ice Age, things are going to
be changing in the landscape around us. As landscapes try to recover
after a fire (for example), I wouldn't expect to see the same plants
come back. Perhaps since Joshua Trees need cool temperatures they'll
be moving up the mountains to reach temperatures cool enough for
them. And the Mojave Desert will fill up with plants from the
southern deserts.
It
will take time. The climate is changing and the plants and animals
around here will change too. The landscape will adapt to the new
reality. But me, I'll adapt too. I'll use my air conditioner even
more (hopefully I'll be able to afford it) and buy a toaster oven so
I can still do a little baking during the summer. Of
course there are still a couple
months left where we can
expect summer temperatures. Maybe I should start pricing those
toaster ovens now.
