So what will happen if global warming is true and continues
to persist; global unrest, extreme temperature changes, other terrible things,
the end of all mankind or just a slight temperature rise that will make the
Earth more balmy? Well for starters we would see a lot if not all of the
factors that I mentioned about in my last post exacerbated: temperature rise,
melting of snow & ice reserves, extreme weather events etc. The predicted
temperature on Earth is predicted to rise 2 to 11.5 degrees Fahrenheit by 2100
depending on our level of greenhouse gas emissions according to
National Research Council. In addition to this
by the same date the global average temperature is expected to double the
previous century’s temperature rise. With this increased temperature comes a
massive increase in the melt of snow and sea ice. The NRC published in it’s
2011 paper Climate Stabilization Targets: Emissions, Concentrations, and
Impacts over Decades to Millennia that every time the Earth warms 2 degrees Fahrenheit
about 15 percent decrease of the existing sea ice and a 25 percent decrease in
the summer Arctic sea ice. Which has given way for
reliable models to put 2040 as the earliest possible date for
the Arctic to be ice-free during the summer. The melting of all these
snow and ice reserves will cause the worlds oceans to rise considerably. The USGCRP
2009 report Global Climate Change Impacts in the United States estimates a
2-foot rise in the global sea level by the end of the century.
This will displace millions upon millions of
people around the world especially those in developing nations. All of these changes
would lead to mass die offs of plant and animal life across the globe not to
mention making it harder and more uncomfortable for humans to live. Ultimately
if we do not curb global warming in a moderate to large fashion our children
and our children’s, children will be growing up in a much harsher world with a
lot more problems that we could have ever foreseen a couple of decades ago.
