The Eastern United States
has been experiencing a milder meteorological winter than usual, with many
record-breaking higher highs and lows.
Ever-fluctuating global temperatures, which had risen to some degree the
previous few decades for a variety of reasons that are not all fully
understood, have been stable for nearly two decades.
Therefore, with temperatures having
reached a plateau, only a slight increase from the twenty-year mean is likely
to produce broken records, as records have only been kept since the late
Nineteenth Century, at most, which is an insignificant length of geologic time.
Regardless,
the warmer weather has demonstrated how higher temperatures benefit the
environment, as warming necessitates less energy usage for heating. Because of lower demand for energy, less
drilling or mining for fossil fuels is necessary, which, in turn, saves more
energy and also causes less environmental contamination or disruption, and less
energy is required to refine or transport fuel.
What is even more significant is the decreased burning of fossil fuels, which,
in turn, leads to less production of so-called “greenhouse gases” that are theorized
to be responsible for global warming, such as carbon dioxide, thereby creating
a positive feedback loop. In addition,
with rain instead of snowfall, less environmentally-damaging salt is put on
roads.
At times in
geologic history, the earth’s climate swings have been dramatic, as the planet
has been either mostly glaciated or almost not glaciated at all, with tropical
climates even in the arctic. The earth
is currently in another relative interglacial period of its most current Ice
Age. It is reasonable to expect at some
point over the next tens of thousands of years yet another disastrous period of
extreme glaciation, in which case some off-setting global warming would be
welcome.
Indeed, modest global warming would
be beneficial for life, as sea-life would flourish over a larger area and
although there would be even less land, much of the remaining land would be more
vegetated and inhabitable by wildlife and more arable than it is currently.
