Here are
a few bits and pieces to ponder on this President's Day....
As
politicians drag their feet on reducing carbon emissions and others
deny climate change outright, the National Academy of Sciences is
tentatively broaching the concept of geoengineering to cool the
planet.
As in
injecting sulphates into the stratosphere, marine cloud brightening
and sucking carbon dioxide from the air and burying it underground.
The first proposals, known as albedo-modification techniques, are
risky, with unknown consequences, and do nothing to address the
associated problem of ocean acidification. But they're appealing
because they could be done with existing technology. However, as the
Associated Press reports:
[O]nce
you start this type of tinkering, it would be difficult to stop
because warming would come back with such a force. So a decision to
spray particles into the air would have to continue for more than
1,000 years.
Removing
the carbon dioxide produced by burning coal, oil and gas would be
costly, require new technology and take decades to cool the planet.
But it would actually treat the cause of man-made global warming.
Both
approaches are detailed in a two-volume report that was requested by
U.S. intelligence agencies, which have long recognized the political
and social instability that could result from food shortages,
prolonged droughts, coastal flooding and other weather changes
associated with climate change.
The AP
report continues:
Panel
chairwoman Marcia McNutt, editor of the journal Science and former
director of the U.S. Geological Survey, said in an interview that the
public should read this report "and say, 'This is downright
scary.' And they should say, 'If this is our Hail Mary, what a scary,
scary place we are in.'"
Some
scientists say it's time to begin small-scale outdoor tests of the
solar radiation management (SRM) concept, which works by creating a
cloud cover that mimics the natural effects of large volcanic
eruptions. But McNutt and other scientists say some sort of oversight
is needed. The AP quotes McNutt as saying:
“Civil
society needs to engage in these discussions where the line is to be
drawn.”
But when
civil society can't civilly discuss genetic engineering, vaccinations
and so many other topics, how is it going to debate an issue of this
magnitude?
The
oceans are also in deep trouble, with The Week summarizing a report
in Science magazine that warned human activity — plastic pollution,
carbon emissions, overfishing, etc. — is irreparably damaging the
world's oceans, which could be on "the precipice of a major
extinction event.” It reports:
With
oceans absorbing a quarter of the world's CO2 emissions, they have
become 30 percent more acidic, causing inhibited shell growth in
coral and crustaceans and reproductive disorders in fish. Power plant
emissions — especially from burning coal — put tons of highly
toxic mercury in the air, which settles into the ocean. The mercury
is taken up by sea creatures and concentrated in predatory species. A
recent study found that mercury levels in Pacific yellowfin tuna have
been rising at a rate of 3.8 percent a year since 1998.
Our
oceans contain an estimated 5.25 trillion pieces of plastic — most
of them less than 5 millimeters wide — weighing a total of 269,000
tons.
[M]ost
commercial [fish] species have been reduced by more than 75 percent —
and some by 99 percent.
Like
global warming, the plight of our oceans is an issue that affects
every country in the world. But with each government beholden to its
own voters — and its own fishing, plastic, and energy lobbies —
it's almost impossible to achieve any consensus.
Meanwhile,
the natural environment isn't the only thing out of balance. An Oxfam report found the combined wealth of the world's richest 1 percent
will exceed that of the other 99 percent by 2016. The richest 80
people on the planet had accumulated $1.9 trillion in 2014 — the
same amount shared by the 3.5 billion at the bottom — an increase
of $600 billion in just four years.
While
we're on the topic of the 99 percent, I'll leave you with this quote
from Willie Nelson:
“99
percent of the world's lovers are not with their first choice. That's
what makes the jukebox play.”
