Its impact can be felt
It’s been creating more
vegetation in arctic regions
with the total amount of
reducing, which could
actually inhibit global
A recent study at Lund
University in Sweden looked
to examine this and found
that organisms like bacteria
and fungi are triggered to
break down particularly
nutritious parts of shrubbery
• Much of the carbon and nitrogen on Earth is stored in arctic
ecosystems, in the perpetually frozen ground!
• When this ground warms up due to climate change, it
releases these and more shrubs start to grow instead of the
typical moss, which is hard to break down!
• Shrubs have leaves and roots that are easy to break down
and secrete sugar!
• The researchers found that decomposition organisms such
as bacteria and fungi are triggered to look for nutrient-rich
organic materials with more nitrogen, which reduces overall
What does it mean?
• Most current climate change models don’t consider
the connection between increased shrub
vegetation from ongoing climate change and soil
becoming less nutritious!
• Completely throws a wrench in current climate
