Many areas
of the world have experienced severe droughts in the last two decades, with one
the worst drought periods being the chronic drought that hit western North
America from 2000 to 2004. The result of this drought was not only dying
forests and depleted river basins but also increased climate change impact due
to reduction in carbon sequestration.
Since
carbon emissions continue to grow these type of chronic droughts could soon
become a common sight for many areas all over the world, leading to massive
environmental and economic damage. Even worse, these drought may after certain
period of time be seen as the good old days because climate change is set to
show us even scarier face in years to come.
The chronic
droughts lead to massive destruction of vegetation, and this releases more
carbon dioxide into the atmosphere, further amplifying global warming effect.
The trees
and plants are large carbon absorbers and their increased mortality means that
their ability to sequester carbon is going to severely decline with frequent
droughts and resulting wildfires.
The current
drought in the American Midwest is also said to be directly connected with
climate change and global warming. If
the world fails to reduce global carbon emissions, the future will look much
worse.
The
infamous 2000-2004 drought had massive negative impact on precipitation, soil
moisture, river levels, crops, forests and grasslands, and this current drought
in Midwest could follow this pattern, and was already called the worst since
the Dust Bowl.
The
scientists from the Oregon State University said in their latest study that „the
situation will continue to worsen, and that 80 of the 95 years from 2006 to
2100 will have precipitation levels as low as, or lower than the 2000-2004
drought“.
The worst
part of this story is that droughts are just one of many scary faces that
climate change has.
