As science and
modern technology have improved, so has our awareness about the epidemic of
climate change. One of the main contributors to climate change is a dramatic
increase of greenhouse gases in the atmosphere. When people hear the term
“greenhouse gas” they generally imagine Carbon dioxide (C02). However, the gas
methane is 23 times more potent than C02, and unlike C02, it is invisible to
the human eye. If you’ve ever passed a factory smokestack and wondered why
there was no ominous billowing smoke, chances are it was emitting methane.
Another major contributor is the agricultural industry, in which the gas
byproduct of grazing livestock can be attributed for 14% of atmospheric
methane, and this number is only expected to grow with an increase in demand
driven by growing populations (Silverman). A new advancement in the field of
infrared imaging can help scientists quantify just how much methane is being
produced at specific data points including at waste disposal sites, factories,
and barns housing cows and other grazing livestock. Before this advancement,
methane emission data could only be obtained from satellite imaging which only
show concentrations of methane in certain areas, rather than pinpoint and
quantify the sources.
The camera, which
detects infrared signals from gas emissions that are either hotter or colder
than the surrounding air, can be used from up to 700 meters away, allowing it
to be used from helicopters to quantify methane outputs from sources such as
lakes or forests (Hadlington). The implications of this advancement are endless
in the field of environmental science, and I think it will help scientists
learn how methane is cycled in our atmosphere, as most of this process is still
unknown.
In previous years,
society has been in the dark about exactly how things like daily
transportation, agriculture, and power generation adversely affect the
environment. Now with advancements such as infrared cameras that can detect
previously invisible threats, we can work on reducing these emissions. Whether
it be stricter production regulations, lower emission standards, or developing
more efficient parts, hopefully with this advancement we come one step closer
to reducing one of the greatest threats mankind faces in future generations. Businesses
may object to stricter regulations if it negatively affects their bottom line as
it often necessitates buying more efficient equipment, operating plants for
fewer hours, etc, however if the camera can prove methane emissions are too
high, the businesses should face repercussions.
