Meteorologists and emergency managers from
the high Plains to the Appalachians are on alert as the U.S. has the year’s
first widespread bout of severe weather. The key message: Have a Plan.

The Climate Change Discussion
After the winter’s
snows, residents of the Northeast might disagree with the “first” bout of
severe weather in 2015! And, with regard
to the bulletin above, climate scientists warn us to not confuse weather (a
single episode) with climate change (observed facts over the long-term). Perhaps Noah or those who were in the path
of Hurricane Sandy might be reluctant to accept this distinction as both weather
events re-arranged the environment. The
increasing frequency of severe weather occurrences, observers say, are the result
of trapped warm air above us caused by human activities. The change in weather patterns is part of the
climate change that is modifying our landscape.
Change should not
be a surprise; the climate and environment are ever changing. Five hundred million years ago receding
oceans left the serrated ridges we see on the massive rock formations along our
roads. Fifty million years ago Mole
Hill stopped erupting and polluting the air with gases and dust. Five thousand years ago man began devising
written languages that allowed him to describe his environment and to observe and
report on changes. The newest force affecting
environment is man with the capability and intelligence to do well or to do harm. People who distrust scientific discourse and
people who deny existing change are often described as mentally lazy,
politically angry, or economically beholden to a special interest. Those on the opposite side are deemed doomsday,
hand-wringers and may also be guilty of the same traits as the deniers. Most people
are somewhere in the middle between the deniers and the doomsayers. Opinions on
what action to take on climate change is far from unanimous.
Efforts to solve our environmental problems
need to include personal, local, state, national and even international action. Given recent political debates, it may come
as a surprise to Virginians that its State Constitution (Article XI, Section 1)
promises “the commonwealth’s policy to protect its atmosphere, land and waters
from pollution, impairment, or destruction, for the benefit, enjoyment and
general welfare of the people of the commonwealth.” The documentation of climate history (often reduced
to a plethora of graphs) and a discussion of climate change in Virginia illustrate some
of the issues. From the existing records
Virginia once
had a generally stable, predictable climate but the long-term historical data show
recent trends to be otherwise. The
trend lines provide insight into what may be happening in the future. These transitional changes in climate affect
our ecosystems
Flora and fauna changes are climbing mountains, like at Mt. Rogers,
so where a flower that once bloomed only at the base of the mountain is now
found 1,000 feet higher. A flower that a
few years ago bloomed in Danville in April and
in Leesburg in May is now seen in bloom in Danville in March and in Leesburg in April. These changes are being followed by the
invasive stinkbugs and kudzu entering our neighborhoods. Virginia’s
occurring environmental changes are not bound by jurisdictional borders. The
State border is not a barrier to coal dust and acid rain carried on winds from
the Tennessee and Ohio Valleys. The “outside” factors as well as local factors
are causing deforestation affecting the canopy of our trees that moderate
temperatures and cleanse our air. Regional
and national programs are needed to address the problems.
