That's right, folks. Despite what you
may have heard from the pulpit, a certain infotainment channel, or
the talk radio host who still believes that FEMA camps are being readied to cart us away – climate change
is settled science. It is no longer a hypothesis (commonly but
erroneously referred to as “just a theory”) but in the realm of fact, to the same extent that we can know that the earth is not flat.
There is also a strongly supported hypothesis that this phenomenon is
caused by human activity. The sheer percentage of scientists who
agree—along the weight of those opinion—combine to form
consensus. Since the discussion of how we can make the world a better
place ought to be undertaken from the perspective of consensus, we
shall take these considered opinions to heart. We are melting the
polar ice caps.
I want to make the extent of the
consequences of our actions crystal clear. I want to show you the
sheer magnitude and speed of the change that's happening now. But
first, please join me in an experiment. If you will, get a glass of
water, a cube of ice, a timepiece, and something you can measure
with. When you get back, check the time, drop the cube in the water,
measure the ice cube in the water, and then figure out how you'll
know when the ice cube is half its size. Try to capture the moment
when the cube is half its size. Ready? Welcome back.
The area of north pole ice cap we
lost—we melted—between early fall of 2010 and early fall of 2011
was roughly the size of New Mexico. Every time a mass of ice cap
melts, it is proven that large quantities of methane (CH4) and carbon
dioxide (CO2) are released. It makes no difference if you believe
that God put the gases in the ice or that natural emissions from
animals like the wooly mammoth were frozen in the ice over tens of
thousands of years. The important point is what these gases are known
to do. They are greenhouse gases. They make the average
global temperature higher, and methane has the strongest effect.
How's your ice cube? If you look closely, do you see any bubbles in
the glass yet? Measured? Good.
So
just imagine the total animal population of the planet just broke
wind. Now imagine that the entire animal population of the planet
breaking wind for tens of thousands of years and every winter, a
portion of the gases dissolved in the ocean—which the tides
constantly stir in from our atmosphere—gets trapped in the two big
chunks of ice on the top and bottom of our globe. If you can imagine
that, and then imagine them all getting released very quickly, great.
How's your ice cube now?
The
other property of our polar ice caps which is very important to
concept of climate change is called “albedo”. It the degree to
which the sun's rays are reflected back or absorbed. The light sand
on a beach might be hot, but it reflects light somewhat, as does the
water, keeping everything much cooler than the blacktop on the
street, which absorbs the light. Now you should be able to understand
what's called “positive reinforcement” whereby the gases released
make the earth warmer and the loss of bright, shiny ice does, too.
So
the loss of polar ice cap material should increase more rapidly as
time progresses, and that's what we're seeing. Between early fall of
2011 and early fall of 2012—just last week—we melted an area of
north polar ice cap the size of Texas and Oklahoma combined. That's 300,000
square miles. And there is only 1,300,000 square miles left. You may
want to check your ice cube now, if there's anything left of it. And
say goodbye to more than your ice cube.
The
report offered by scientists from NASA, Columbia University, et. al.
(and Al) predicts that the north polar ice cap will melt by the end
of the decade. You may be right to be skeptical of that claim, but
not because it's too sensational, but because it isn't sufficient to
assess a process which is being positively reinforced exponentially.
Let's say that for the next measurements we take of the polar ice
cap, we only lose the amount of ice we lost this year. That gives us
a total loss
in the summer of 2014 or 2015. Greenhouse gases from an area roughly
four times the size of Texas will begin to work on the Greenland ice sheet and the south polar
ice cap as well. Now we have a problem.
If we melt the Greenland ice sheet, a distinct possibility, sea levels will rise 20 feet.
If we were actually able to melt Antarctica completely, the total rise in sea level
would amount to 90 feet. But 20 feet is a big deal. This is Manhattan. This is Shanghai. This is
Mumbai. This is London. This is Cape Town. This isn't just the
greater Miami area. This is a good chunk of Florida. Seriously. This is the home of
90% of the world's population—our sea coasts. Say goodbye to the
Seahawks, the 49ers, the Saints, the Rams, the Chargers, the Raiders,
the Dolphins, the Buccaneers, the Giants, the Jets, and the Redskins
as you know them. Say goodbye to the White House. Say goodbye to
every coastal beach on the planet. And say hello to some new
neighbors.
There's
a demographic which plenty of people understand—it's our electoral
map. During the Bush years, the Pacific states came to be known as
the Left Coast because of a strong Democratic leaning. Most of the
Democrats live along the nation's coasts. Most of the Republicans
live inland. If you are a Republican, you have an opportunity right
now to choose the degree to which you respond to climate change and
how well you play with others. But remember this. It is also settled
science
that altruism (good deeds done to YOU) increases as social distance
(your barriers to others due to race, religion, nationality, and/or
communication obstacles) decreases. Translation: be a Good
Samaritan—a racial distinction you could easily apply to being good
to others regardless of whether you identify with them. Whether you
are from “Judea” or “Samaria” we are about to reduce our
social distance dramatically because we melted the ice caps and made
the seas rise. Please be civil and welcoming. Assume good faith. The
earth is a closed system and we are all in it together.
