DON'T WORRY: Keystone XL Pipeline Would Be Safe From The Climate Impacts It Would Help Cause
Don’t Worry: Keystone XL Pipeline Would Be Safe From The Climate Impacts It Would CauseBy Brad Johnson, Guest Blogger on Mar 6, 2013 at 10:45 am
According to John Kerry’s State Department, the controversial Keystone XL tar sands pipeline will be safe from the climate impacts to which it will contribute.
The department’s contractor-written Draft Supplemental Environmental Impact Statement estimates, and then dismisses, the pipeline’s massive carbon footprint. But the statement also determines that the global warming the pipeline’s dirty crude will cause will not affect the pipeline itself because it “will be buried deep enough”:
During the operations period, climate change projections suggest the following changes:
Warmer winter temperatures;
A shorter cool season;
A longer duration of frost-free periods;
More freeze-thaw cycles per year (which could lead to an increased number of episodes of soil contraction and expansion);
Warmer summer temperatures;
Increased number of hot days and consecutive hot days; and
Longer summers (which could lead to impacts associated with heat stress and wildfire risks).
The pipeline would be buried deep enough to avoid surface impacts of climate changes (freeze-thaw cycles, fires, and temperature extremes).
