Global Warming Skeptics Rejoice at D.C.
Blizzard
Every time the national news reports on a rare blizzard (such
as the one occurring in Washington, DC) or unseasonal freezing
temperatures (such as those that threatened Florida citrus crops
last Fall), the global warming deniers get on Facebook and Twitter
and proclaim victory. Grasping "global warming", however,
requires more than a first-grade level understanding of the word
"warming" (No disrespect to first graders.)
What Global Warming IS
Global warming is a term that refers to the overall warming of
the Earth's surface. The effects can include changes in weather
patterns causing flooding, drought, and an increase in damaging
storms. "Global warming" while accurate in describing
the overall rise in Earth's surface temperature, does not accurately
describe the effects of such a temperature rise. This is why
scientists prefer, and in fact first used, the term "climate
change."
What Global Warming is NOT
Global warming is not a declaration that it will never snow again
or get really cold again. We are experiencing a warming trend,
but we will still experience fluctuating weather patterns inside
this trend. A blizzard or a deep freeze is weather--not evidence,
yet, of any thing more. "Evidence" is an accumulation
of data and facts that can prove a conclusion. There remains
much more evidence of global warming than climate cooling when
we look at the whole picture and not just a snapshot.
It's not out of the question that the current trend could
shift
that is what everyone is hoping for, but the fact
that we still have winters doesn't mean we are out of the woods
or off the hook.
