Biodiversity
loss is one of the biggest environmental issues of modern world, and the
widespread effect of climate change is making things even worse. The latest
study published in the Nature Climate Change magazine has studied the
effect of retreating glaciers on biodiversity. The conclusion was that the continuous
melting of glaciers has negative effect on biodiversity in affected areas.
The
scientists have studied temperate, arctic and tropical regions (Alps, Alaska
and the equatorial Andes) in order to find the correlation between the glacial
coverage and biodiversity loss. They have discovered that in situations where
„glacial coverage is reduced to the point where it only covers 30 to 50% of the
drainage basin, several species begin to disappear.“
They have
also calculated that the entire melting of the glaciers in these areas would
result in huge loss of biodiversity, where between 11 and 38% of the animal and
plant species could go extinct, including many of endemic species that can be
found only in these areas.
We are not
just talking here about the loss of biodiversity in these areas but also about
the huge water shortage issue for many places across the globe. The worldwide
melting of glaciers threatens to eliminate the water supply for numerous towns
in valleys, and water could very soon become a very scarce resource for many regions
of the world.
This is
just one of many scientific warnings about the growing impact of climate
change. World leaders still don't look particularly worried about it, and the
climate change issue is still far from being the top issue on global political
agenda. As always, finance and economies are far more important to world
leaders than environmental issues.
Biodiversity
loss will only grow as climate change impact becomes stronger, and if we fail
to do something quick we will pass the point of no return where the world will
be helpless to do something effective against climate change (the global
temperature increase of two degrees Celsius).
The glacier
melting is just one of many climate change faces, all of which can result in
one scary future. This future could soon become our reality…
