It’s Never Happened Before
Scientists
have never seen the ice sheet immediately north of Greenland break up. Never in
recorded history. Until 2018. Surprise, surprise. The Guardian U.K. (August 21st)
explains: “This phenomenon – which has never been recorded
before – has occurred twice this year due to warm winds and a climate-change driven heatwave in the northern hemisphere.
“One meteorologist described the loss of ice as ‘scary.’ Others
said it could force scientists to revise their theories about which part of
the Arctic will withstand warming the longest… The sea off the north
coast of Greenland is normally so frozen that it was referred to, until
recently, as ‘the last ice area’ om the coast
than at any time since satellite records began in the 1970s. because it
was assumed that this would be the final northern holdout against the melting
effects of a hotter planet.
“But abnormal temperature spikes in February and earlier this
month have left it vulnerable to winds, which have pushed the ice further away
from the coast than at any time since satellite
records began in the 1970s… Ice to the north of Greenland is usually
particularly compacted due to the Transpolar Drift Stream, one of two major
weather patterns that push ice from Siberia across the Arctic to the coastline,
where it packs.
“Walt Meier, a senior research scientist at the US National Snow
and Ice Data Center, said: ‘The ice there has nowhere else to go so it piles
up. On average, it’s over four metres thick and can be piled up into ridges 20
metres thick or more. This thick, compacted ice is generally not easily moved
around… However, that was not the case this past winter (in February and March)
and now. The ice is being pushed away from the coast by the winds.’…
“The latest readings by the Norwegian Ice Service show that Arctic ice cover in the Svalbard area this week
is 40% below the average for this time of year since 1981. In the past month,
at least 14 days in the past month have hit record lows in this region.
Although thinner ice elsewhere in the Arctic means this is unlikely to be a
record low year overall, they are in line with predictions that there will be
no summer ice in the Arctic Ocean at some point between 2030 and 2050…
“As well as reducing ice cover, the ocean intrusion raises
concerns of feedbacks, which could tip the Earth towards a hothouse state… Freakish Arctic temperatures have alarmed climate scientists
since the beginning of the year. During the sunless winter, a heatwave raised
concerns that the polar vortex may be eroding.”
As these new realities sink in, as flooding is slamming into the
East Coast just as wildfires rage out of control in our West, as hurricanes
continue to mount in intensity and coastal flooding and sea rise are the norm, as
disease-carrying insects migrate with the rise in temperatures, the Trump
administration remains committed to denying the existence of climate change.
Instead, our government is proposing a new set of rules under our environmental
laws to allow more greenhouse gasses into the atmosphere.
In addition to trying to freeze automotive mileage/emissions
required, the Trump administration is also going one additional step to promote
the use of the most polluting form of industrial carbon – coal – like never
before. “The new power plan would relieve the electricity
industry — the second-largest producer of potent greenhouse gases nationwide —
from aggressive goals for reducing its carbon footprint. Heavily polluting coal
plants that would have been forced into retirement under the Obama-era
guidelines get a new lease on life under the Trump blueprint, which allows them
to continue operating with modest modification.
“In
some cases, states may be permitted to ignore federal guidelines for certain
plants altogether and pursue their own strategy…
“Climate-conscious
states like California are already mobilizing to fight, arguing the
administration’s approach violates the Clean Air Act. The Supreme Court ruled
in 2007 that the law requires the federal government to take steps to combat
air pollutants that are warming the global climate.
“Administration
talking points leaked to the media say the replacement of the Clean Power Plan
is a signal ‘to the nation that the war on coal is over and a new era of energy
dominance is underway.’ A spokesman for the Environmental Protection Agency,
which oversees emission regulations, declined to comment on the draft plan.”
Los Angeles Times, August 20th. The sheer ignorance, the lack of
shame, the rejection of overwhelming scientific support, the human suffering
and the trillions and trillions of dollars of damage all over the earth that
this callous disregard for reality represents are simply staggering.
I’m Peter Dekom, and I wonder how history
books of the future will depict this dark period in our human experience… if
there still are history books being written.
