The gradual increase in Earth's temperature known as global
warming has put our world on an unstoppable course toward a climate catastrophe
that is causing devastation in the shape of floods, droughts, wildfires, and
the rapid extinction of species. Astronomy, on the other hand, is a predicted
field where specialists have already begun to notice the impact. Back in 2020,
a study presented in Nature Astronomy described how the sensitivity and calibre
of readings from crucially significant scientific observatories like the European
Southern Observatory's Very Large Telescope are being impacted by the
unprecedented rise in temperature and haphazard atmospheric water levels (VLT).
What about remedial measures like turbulence in the
atmosphere? The delay caused by these corrections, however, results in an image
artefact known as a wind-driven halo. These wind-generated halos are
discernible in about 40% of the photographs, greatly reducing the contrast of
the scene. However, it seems that the rapidly deteriorating climate won't be
reversed soon, and the astronomical community's worries are growing
along with it.
Another in-depth study on how man-made climate change is
obscuring our understanding of the cosmos was published in the Astronomy &
Astrophysics magazine in 2022 by a group of academics led by the University of
Bern. The research anticipates that significant astronomical observatories in
Chile, Mexico, South Africa, Australia, the Canary Islands, and Hawaii would
experience increasing temperatures and atmospheric water content levels based
on data from climate change models covering the globe.
There isn't Much Positive News.
The time window for performing observations will be reduced
due to the change in atmospheric conditions mentioned above, but there will
also be a net loss in the quality of the observation data. Lead author Caroline
Haslebacher draws attention to the negative effects of these drastic changes on
sophisticated telescopes and issues a warning about "a higher risk of
condensation due to an increased dew point or malfunctioning cooling systems,
which could lead to many air turbulence in the telescope dome."
However, as climate change patterns increase in the upcoming
years, more than simply the quality of observations will be impacted. It makes it harder for researchers to select locations for putting up
next-generation telescopes. Increasing maintenance expenses for astronomical
observation facilities will add to the financial burden of escalating
construction prices.
The string of negative news, however, continues. One highly
ambitious suggestion among the many that scientists are looking at to perhaps
lessen the effects of global warming and repair Earth's climate is
bioengineering the planet's atmosphere. One idea to reduce the temperature of
the earth is to produce clouds that reflect the sun artificially. However, as a
result of the increased brightness of the night sky and the consequent light
pollution, astronomical observations will become much more challenging.
