Just
a short time ago there were very few articles on climate
disruption.Now there’s a preponderance of them.
We're
Obliterating Global Temperature Records, and There's No End in Sight
15
September, 2015
One
after another, each of 2015's summer months have been among the
hottest ever recorded on Earth. And a trio of new studies out this
week, from three different countries, confirms that temperature
records just keep tumbling—falling victim to an unusually
massive El Niño climate
event gathering strength in the Pacific, as well as unrelenting
man-made climate change, which is cooking the entire system.
On
Monday, Japan's Meteorological Agency said that
this August was the hottest August worldwide since 1891, when its
records begin. August was 0.81 degrees above the 1981-2010 average,
smashing 2014's record.
Data
from Japan's Meteorological Agency shows 2015's August was the
hottest August in more than 120 years. JMA
And
finally, major
research from
the United Kingdom's Met Office released
this week concluded that 2015's overall temperatures are running at
or near record levels (at about 0.684 degrees above the 1981-2010
average)—which suggests the next two years could be the hottest on
record around the world.
"We
know natural patterns contribute to global temperatures in any given
year, but the very warm temperatures so far this year indicate the
continued impact of (manmade) greenhouse gases," said Stephen
Belcher from the Met Office, in a news release. "With the
potential that next year could be similarly warm, it's clear that
our climate continues to change."
The
Met Office says this year's El Niño— the global climate event
that occurs every five to seven years, bringing drought to places
like Australia while heaping rain on the western United States—is
likely contributing to record temperatures. (Sadly,it's
unlikely to help quench California enough to break the drought.)
The
El Niño itself could break records. "Recent oceanic and
atmospheric indicators are at levels not seen since the 1997–98 El
Niño," Australia's Bureau of Meteorology said
on Tuesday,
adding that the big climate event is unlikely to subside before
early 2016.
El
Niño is also probably contributing to the unusually active
hurricane season in the Pacific. The Met Office says tropical
cyclone activity across the northern hemisphere this year is about
200 percent above normal. Six hurricanes have crossed the central
Pacific, more than in any other year on record.
This warming is due to climate change -- and yes, we scientists are sure that this isn't a natural cycle.
Taking
the Oxygen Out of the Room
20
September, 2015
The
expression "taking the oxygen out of the room" is commonly
used to mean that someone is getting unwarranted attention at the
expense of others. For example, in the political circus de jour, the
expression is often used to describe how Donald Trump, who thinks he
is really, really smart, has received disproportionate media coverage
compared with the 16 other wannabes. But, whether the discussion is
about immigration, Planned Parenthood, Hillary's email, or something
totally really inane, clearly it is understood that no one is
literally taking all the oxygen out of the room -- that would be
deadly.
However,
in the real world, it turns out that oxygen is being "taken out
of the room" -- or in this case, the oceans. Literally, oxygen
is being lost, and the reason is the upper ocean is warming.
This warming is due to climate change -- and yes, we scientists are sure that this isn't a natural cycle.
We
live on a planet where the temperature of the air is the hair on the
tail of the dog. The dog is the ocean.
Over
90 percent of the change in the heat on Earth driven by burning
fossil fuels since the Industrial Revolution isn't in the atmosphere.
It is in the oceans. That is a whole lot of heat.
Just
as hot air rises, warm water floats over the cold waters of the ocean
interior. The upshot of heating the upper ocean is that it makes it
harder to get the cold waters in the deep ocean to mix to the surface
-- and that means that as the upper ocean gets hotter, and the ocean
interior stays cold, the ocean is becoming increasingly stratified.
That
is not good if you need oxygen.
The oxygen in the ocean interior gets there by being exposed to the atmosphere. Less mixing, means less exposure -- which means less oxygen gets into the oceans.

So
what?
Oxygen
isn't just important for fish and other animals -- it's also
important for microbes. Microbes need oxygen for many processes that
are critical to the core functions of the planet. One of those
functions is to help make nitrogen available for phytoplankton -- the
microscopic algae in the ocean that are actually generating half the
oxygen we breathe.
So
while the candidates for the highest office in the land are furiously
discussing defunding Planned Parenthood, the oceans are slowly dying
because they are becoming deoxygenated.
There
are many effects of climate change that we can easily see -- the
drought in California, the loss of glaciers from the Himalayas and
the Andes to Greenland and Alaska, the record setting heat waves in
the Middle East and southern Asia.
It
is those effects that we can't see that are really critical -- the
loss of oxygen in the ocean one of the most concerning to me.
In
the end, nature couldn't care less who wins an election or whether or
not that exalted person believes climate change is due to humans. The
fact is that we are extremely efficient at finding, extract and
burning. fossil fuels.
In
the United States, our carbon "foot print" amounts to 110
pounds of carbon dioxide per person per day.
We
just dump the gas into the atmosphere -- freely. And it freely
absorbs infrared radiation from the Sun and makes this planet warm.
The more we dump, the warmer the planet. That is physics. You don't
get to vote on whether that is true or not. If you don't believe in
physics -- try living on Venus, where the carbon dioxide levels are
so high that lead will melt on the surface of the planet.
We know how to take it out of the atmosphere -- but it's expensive.

There
is no such thing as a free lunch.
Unless
we move much more rapidly towards building and deploying energy
systems that don't emit carbon dioxide (including nuclear power),
Earth will continue to slowly cook and the unintended consequences
will be... well, consequential.
I
don't worry about the microbes -- they will outlive us an they will
go on providing their services that make this a habitable planet.
We
are a fragile species -- and we don't even know it.
It
would appear we aren't as smart as we think.
Whoever
is running for high office should know they don't control the planet.
A
little hubris may help us find solutions to our problems.
