Resilience: an ability to recover from or adjust easily
to misfortune or change – Merriam Webster Dictionary
Adaptation: the process of changing to suit different conditions – Oxford Dictionary
I hear the words resilience and adaptation bandied about a
lot. Along the coast, it can mean elevating homes and streets, upgrading
coastal infrastructure, and building seawalls.
But what about Westborough? Do we need to be
resilient? We do. Fortunately, rising sea level isn’t an issue for us.
Let’s start with the early July heat wave, which affected a
large portion of North America, caused by a large stagnant high pressure
system. Temperature records were broken in many places.
Was THIS heat wave “caused” by global warming? No single
weather event can be pinned on global warming. What scientists have been saying
for many years is that our changing climate has made such events more likely,
which is supported by weather records and charts freely available from NOAA.
Bottom line – we will see more frequent heat waves.
During the last heat wave, residents received reverse 911
messages that the Senior Center was opened as a cooling center, a godsend for
the great many of us who don’t have air conditioning in Westborough. In the 17
years I have lived here, I don’t recall the town having to take this measure
until recently. Maybe someone can tell me if I am wrong.
As temperatures have increased, so have extreme weather
events. A warmer atmosphere holds more moisture, so in the temperate
Northeastern US, we can expect more intense storms (in summer AND winter).
According to the U.S. Global Change Research Program, the amount of
precipitation falling “as the heaviest of 1% of all daily events” has increased
71% in the Northeast since 1958.
The latest FEMA flood maps show that the impact of 100-year
or 500-year flood events in Westborough would not be significant. Downtown
Westborough is adjacent to Cedar Swamp, which has a huge capacity to store
runoff. Since the town does a very good job of maintaining its drainage
infrastructure, we have made ourselves more resilient to such storm events.
The town also manages its water system in the face of
droughts, like we had in 2016. We do not over pump our wells and we take care
of Sandra Pond. The town repaired the Sandra Pond dams so they better withstand
major storms. The town took down a lot of trees, but state dam regulations
required it. Again, foresight and good management make the town more resilient.
Another step would be to fix the culverts under the railroad
that crosses Cedar Swamp, which were designed to allow water to drain south
into the Sudbury River but they collapsed or were blocked decades ago. When one
major culvert at the Transflow rail yard off Flanders Road was fixed a decade
ago, water levels in the eastern portion of Cedar Swamp dropped several feet.
If the culverts closer to town were fixed, downtown Westborough would be much
better protected.
Of course getting the railroad to repair them is another
matter. It’s expensive because the rails need to be kept open while the repairs
are performed.
Insect-borne diseases are another issue we have now that we
did not have to worry about when I was a kid in the 1970s. Anyone even spending
time on their lawn in Westborough, let alone the woods, should routinely check
for ticks.
Ticks are tough creatures and are surviving our warmer
winters. According to the Tufts University Lahey Clinic, ticks are a major
vector not only of Lyme disease, which is debilitating enough, but Babesiosis
(causes anemia), Tularemia, and Rocky Mountain Spotted Fever, both of which can
be fatal.
Massachusetts already deals with Mosquito-borne diseases
such as West Nile virus and to a lesser extent, Eastern Equine Encephalitis.
The Asian Tiger mosquito is a vector for Dengue and Chikungunya. This species
is steadily migrating northward from the Deep South. It’s already found as far
north as southeastern Connecticut.
I know this all sounds scary, but everything I discussed is
a recognized issue documented in the Massachusetts State Hazard Mitigation and
Climate Adaptation Plan (resilientma.com).
Regardless of whether you think humans are causing the
climate to change, the fact is that it IS changing and quickly.
The trends are pretty clear, which is why we have to be
resilient.
