JENNIFER
FRANCIS: HOW THE ARCTIC DRIVES WEIRD WEATHER
In
the 1990's we talked about "global warming". The planet
would slowly warm, scientists told us. Maybe that would be good for
people living with cold winters - kind of like Florida slowly moving
to your house. Then we learned other things would be affected, like
rainfall and rising seas, so we called it "climate change".
Around 2008, scientist John Holdren said it should be "climate
disruption".
Meanwhile,
Europe has been back and forth between cold, and strings of rainy
storms. Instead of nice warm winters, the Eastern United States has
experienced a series of Arctic cold waves and record-setting
snowfalls. I know my East
Coast listeners are praying these kind of vicious winters are not the
new normal. Is
it possible they are?
In
a 2012 paper titled "Evidence
linking Arctic amplification to extreme weather in mid-latitudes",
Dr. Jennifer Francis of Rutgers University offered a clear answer,
based on observations. The
Jet Stream,
that high air current that can drive weather patterns, is now slower
and wavier, due to warming in the Arctic. Her work has generated a
little criticism and a lot of support.
Now
three years later, Dr. Francis is back with co-author Stephen J
Vavrus, with an update. They say we have entered a new era driven by
something called "Arctic amplification". With so much at
stake, it's a pleasure to welcome Jennifer Francis back to Radio
Ecoshock. Her latest paper is "Evidence
for a wavier jet stream in response to rapid Arctic warming."
That was published in the journal Environmental Research Letters in
January 2015.
Here's
a great explanation of the Polar Vortex weather and the Arctic
science by
Climate Progress blogger Joe Romm.
I'd
like to look further into several issues raised in this interview
with Jennifer Francis.
A
NEW ERA OF ARCTIC AMPLIFICATION
First
of all: why does this new paper say we are in a "new era"
of Arctic amplification, or AA. We have reliable temperature and
other weather readings from the Arctic starting in 1940. According to
this paper, Starting in the 1990's, in the same time frame as sea ice
declined, Arctic amplification could be seen in all four seasons -
something not seen in records from the time records began in 1940, to
1990. So that's one sign.
Going
further, the paper says, quote:
"It
is important to note the recent emergence of the signal of AA from
the noise of natural variability: since ~1995 near the surface and
since ~2000 in the lower troposphere. This short period presents a
substantial challenge to the detection of robust signals of
atmospheric response amid the noise of natural variability. Thus for
this study we define the period from 1995 to 2013 as the 'AA era.'"
I
spent a little time with Dr. Francis on the natural cycle called the
Arctic Oscillation, and sometimes called the Northern annular mode.
We'll stick with Arctic Oscillation or AO.
NOTICE
THIS STATEMENT BY JAMES HANSEN, WHICH EXACTLY EXPLAINS THIS PAST
WINTER ...
"When
the AO index is negative, there tends to be high pressure in the
polar region, weaker zonal winds, and greater movement of frigid
polar air into middle latitudes."
That's
from Hansen's 2009 paper "If
It’s That Warm, How Come It’s So Damned Cold?".
It's too bad climate denier Senator James Inhofe is too dumb to
understand it.
I
specifically asked Jennifer Francis about the Arctic Oscillation,
because if that's all it is, the awful weather pattern in the U.S.
Northeast will just go away when the Arctic Oscillation goes
positive. Francis has three answers really. First: the Arctic
Oscillation is
not a final indicator of getting a disturbed Jet Stream, and a Polar
Vortex in North America. This past winter had a positive AO, and
still got hit with polar weather further south. Secondly, we can see
the pole is warming, with ice melting, permafrost thawing, and a much
warmer winter in Alaska - because of climate change.
Finally
though, the super-cold winters in Eastern North America will get less
frequent over time because we are warming the whole planet. I did a
Radio Ecoshock show titled "Summer
in March"
in 2012 because that winter was so freakily warm. Folks were playing
tennis in New York city parks in January that year. Parents in Quebec
couldn't get the traditional outdoor skating rinks to freeze.
The
unpleasant answer is we have caused climate disruption. Expect the
unexpected, good and bad.
NOT
EVERYONE AGREES - YET
As
far as other scientists expressing doubt about the work of Francis
and her collegues - that is what scientists do! Underneath those
quiet proper exterior, scientists are actually cut-throat thinkers.
They live to disprove what others thought was real.
There
has been some criticism of the work published by Jennifer Francis.
For example, in December I interviewed Dr. Kevin Trenberth of the
Snow and Ice Data Center. He hesitated to agree with your work, and
suggested things like Tropical Storm Nuri hitting Alaska are also
important factors. There was even a
paper out from Elizabeth Barnes of Colorado State University which
said she couldn't duplicate the Arctic-Jet Stream connection with her
methods. You can download or listen to that December 2014 Radio
Ecoshock interview with Kevin Trenberth here.
After
the interview, a listener sent this
link to a seemingly contradictory paper by
another Radio Ecoshock guest, Noah Diffenbaugh.
But
I'm with Jennifer Francis on this. First of all, the observation of
the distortion of the Jet Stream is indisputable. We are experiencing
this now, all too often. We can argue about whether there is enough
proof that warming in the Arctic is causing a wavier Jet Stream, but
so far it all make a lot of sense. It's based on the basic physics
that warmth will move toward cold. That's what powers our weather
systems, the difference between heat at the equator and cold at the
poles. Along with the spin of the Earth, the temperature difference
creates wind on the planet. It doesn't seem possible to me that the
Arctic could be up to 30 degrees warmer than in the past, without
affecting weather world-wide.
Further
research published in August 2014 by the Potsdam Institute for
Climate Impact Research (PIK)
supports the wavy Jet Stream - Arctic connection, using different
methods.
If
you read through the paper "Evidence for a wavier jet stream in
response to rapid Arctic warming" you'll have to learn a few new
terms. Just crank up Wikipedia and Google searches. As a reward,
you'll get the big picture of what is driving weird weather in your
world.
THE
IPCC AND RPC - SCIENCE OR SCIENCE FICTION?
Evidence
is growing that the Paris Climate talks at the end of 2015 are an
exercise in futility. The European Union, considered the most
climate-aware and progressive block at the table, are proposing
emission levels which scientist I talk with say are not survivable,
at least not for human civilization.
The
latest document from the EU calls
for cuts in greenhouse gas emission of “at least” 60% from 2010
levels by 2050. First of all - what happened to the 1990 greenhouse
gas levels used in most previous talks? Global
greenhouse gas emissions went up 24% from 1990 to 2004,
and rose another 3% annually pretty well every year since 2004. We're
way, way higher than 1990. So a 60% cut from 2010 levels doesn't mean
very much.
The
kicker is even if we make that goal, we are headed for a climate
catastrophe, if we are still emitting 40% of 2010 levels in 2050,
scientists guarantee polar ice will disappear over the coming
centuries, in an unstoppable wave of climate disruption. A sixty
percent cut by 2020 might stave off the worst.
Keep
in mind that most other big polluters, especially the United States
and China, are promising nothing like the European goals. And goals a
generation away aren't likely to be met anyway.
How
to international politicians get at these deadly greenhouse gas
targets? They believe in fairy tales. And governments get that
science fiction from the scientists they hire. I'm talking about the
Intergovernmental Panel on Climate Change. The IPCC works out
possible futures they call "Representative Concentration
Pathways" or RCP’s. Learn that jargon, because they are
talking about your future.
These
days, there are three big representative concentration pathways in
the latest IPCC assessment, the one that will be used by diplomats in
Paris. The two lowest carbon pathways are shown on graphs. But the
IPCC doesn't say those graphs assume that humanity will use a
non-existent technology to geoengineer the planet, to remove billions
of tons of carbon dioxide.
A
couple of Radio Ecoshock listeners alerted me to this dangerous
charade. It's explained best by the UK film-maker and climate blogger
Nick Breeze at envisionation. Here's the audio argument from Nick's
latest film warning.
In
this program I play the audio from a new short film by Nick Breeze,
titled "Survivable IPCC Projections Are Based On Science
Fiction". You can find it at envisionation.co.uk.
Nick does some great interviews, often with prominent climate
scientists. It pays to keep visiting his site.

blog entry here.
GET
SOIL ON THE PARIS CLIMATE TALK MENU!
So
the Paris Climate talks are already a sell-out of humanity and all
species, even if they are a "success" which is doubtful.
I'd say the best climate activists can do at this point, is to push
their country governments to do far more, and to include a new vision
of naturally capturing carbon back into the soil.
As
we've heard from recent Radio Ecoshock guests, like Thomas Goreau
(interview here)
and Kristin Ohlson (interview here),
we can lower the burden of greenhouse gases in the atmosphere by
changing the way we do agriculture. That will need a parallel shift
in our whole economy and lifestyles, but it can work. Unlike the
fairy-tale tech of carbon capture and storage, we do know how to put
large amounts of carbon back into the soil.
So
far the Climate Talks do not even include the soil carbon option.
Let's try and change that, before it's really, really too late. Get
soil carbon into the Paris Climate talks. Pass the word.
DANIEL
BROOKS: ADVANCE OF THE PARASITES WITH CLIMATE CHANGE
Humans
are changing the planet in many ways. But we are not alone out there.
There are diseases looking for new conquests, and parasites being
spread around the world by air travel, shipping, and resource
extraction. Experts warn we already in a
crisis of Emerging Infectious Disease,
or EID.
We
have one of those experts with us now. Dr.
Daniel Brooks was
a zoology professor at the University of Toronto. He is now a Senior
Research Fellow with the Manter
Laboratory of Parasitology,
at the University of Nebraska. Dr. Brooks is also a visiting scholar
in Brazil and Hungary.
This
week's interview with Daniel Brooks has a couple of key thoughts.
First,
while humans mentally long for a single threat where we can focus,
the natural world is too complex to accommodate our need. Unlike the
movie "The Andromeda Strain", the experts don't think we
will run into a single giant disease or parasite to knock off our
species. AIDS, Ebola and West Nile virus arrive and manage to stay
around, but don't do us in.
WEST
NILE GAINING CALIFORNIA
By
the way, if I sounded disappointed in the West Nile virus after the
initial hype, here's
some news.
The extra-warm dry conditions in California brought the highest level
of West Nile virus ever seen in that state. There were 798 human
cases in 2014, five times the number recorded in 2011 at the start of
this big drought. Twenty nine people died.
You
might think drier weather means less mosquito diseases. But streams
and even rivers that normally keep running enough to stay clear of
mosquito larvae, end up with more stagnant pools to breed. Plus, with
fewer water sources, more species come to those that are left,
meaning a better transfer station for diseases to all kinds of
species.
The
Sacramento-Yolo Mosquito Control is warning Californians to expect
“an intense West Nile virus year.” It's just another unexpected
spin-off of climate change, and the very things Dr. Brooks warned us
about.
DEATH
BY A THOUSAND CUTS
But
the first big thought from the Brooks interview is : with further
warming we will be hurt by a
thousand cuts.
Picture finding a new beetle killing off your apple tree. It's been
brought over from Asia in a furniture shipment. The bug carries a
virus that slowly kills the tree. That gets into orchards all over.
The cost of fruit goes up.
Meanwhile,
house cats get a new virus originally from the tropics, but now
capable of over-wintering in warmer climates. Vet bills, already in
the billions of dollars in North America, go up.
There's
another nasty tropical disease likely to arrive from the Carribean.
It's "chikungunya". Before 2013, this Asian and African
disease was never before seen in the Americas. It's here now, and
likely to arrive in the southern United States, just like Dengue
fever is now in Florida and Texas.
PARASITES
SURVIVE CLIMATE CATASTROPHE
The
second big take-away is that scientists have discovered that disease
agents are very tough. In the interview, we heard about a 100
million-year-old parasite that survived the great asteroid strike 65
million years ago.
When the dinosaur fish is specialized in went extinct, the parasite
did not, and appears now in Arctic birds.
It's
intriguing to hear that parasites can revert to ancient abilities in
their genes to adapt to new hosts, and new challenges. As Dr. Brook
warns at the end, the idea that we are in a golden age of health is
an illusion, and there is no evidence that humans will win in the
end, as climate change combines with international trade and
expanding human populations. Unseen in our Twitter world, humans are
always prone to becoming food for something else.
I
didn't have time in this interview to get into a new concept in
parasitic threats that Dr. Brooks and other scientists are using.
It's called the Stockholm
Paradigm.
Please don't confuse that with Stockholm Syndrome, where a captive
comes to love his or her captor.
After
interviewing Daniel Brooks, journalist
Dominic Basulto in the Washington Timessummarized
it this way:
"The
new thinking, known as the 'Stockholm Paradigm' (not to be confused
with the 'Stockholm Syndrome'), combines four different ecological
concepts – ecological fitting, the geographic mosaic theory of
co-evolution, taxon pulses and the oscillation hypothesis – to
conjecture that pathogens may not really have as hard of a time
finding a new host as we thought. They may already have the
'ancestral genetic capabilities' to switch to new hosts that are
genetically close enough to the original hosts."
The
Stockholm Paradigm is exactly the type of matrix of causes that
breaks our simple human minds. It's hard for us to think about, but
that's how nature operates, and simple is not a requirement for
reality.
LESSONS
FROM THE PLAGUE
Meanwhile,
the news is full of more examples of how climate change will
influence the appearance of new diseases and pests. Just this past
week, a new study from Oslo, Norway re-wrote the history books of how
the plague hit Europe in the 1300's, and kept coming back for
hundreds of years afterwards.
According
to the book "Ghengis
Khan and the Making of the Modern World" about
90% of the people in Hopei province of China died from the plague in
1331. Fifteen years later the disease made it to the Volga River in
Russia. The Mongol empire partly ended because their pony express
system, which likely spread the disease, couldn't find enough riders
left alive. A hat tip to Scott Gardner at the Manter Lab in Nebraska
for that book info.
Scientists
now think that periods of warmer and wetter weather in Asia
stimulated the populations of plague-carrying ticks. And these
were more
likely carried by gerbils,
not the black rat. The gerbils likely spread the plague to pack
animals plying the Silk Road trade route to Europe, rather than just
arriving by ship.
Evidence
seems to show that the plague did not stay resident in Europe's rats,
but instead kept arriving from Asia following warm weather spells
there. Rats carrying the plague were themselves killed off, rather
than harboring the horrible disease.
Europe
was re-infected dozens of times.
Investigating over 7,000 outbreaks of the plague, scientists from the
University of Oslo found that weather in Europe was not a factor. But
a warming spell in Asia was. The plague arrived about 15 years after
each warming period. Like today, other factors like immigration and
wars also helped spread the disease.
We
don't know all the surprises coming our way, as this next warming
pumps up the population of disease-bearing organisms. Oh, and by the
way, a
brand new deadly virus was just discovered in a man in Kansas at
the end of February. He'd been bitten by ticks in the Spring. It took
a while for the US Centers for Disease Control to realize this was a
brand new virus, never seen before.
Check
out this
Washington Post article about
our guest: "The Weird Way that Climate Change Could Lead to New
Disease Outbreaks Around the World".
WHAT
TO DO ABOUT DISEASES
The
best we can do, Brooks says, is (a) admit climate change is real and
then (b) start funding research and building infrastructure to deal
with new pests and diseases we know are coming. Right now even in the
West hospitals are operating on a just-barely basis. Agriculture is
likewise dependent on a business model with no back-up system, and no
fall-back position. It's not like we are rationally ready for a
thousand challenges from the micro-world, much less the insects.
Here
is the source for the new paper, taken from the University of
Nebraska-Lincoln press release:
"Brooks'
and Hoberg's article, 'Evolution
in action: climate change, biodiversity dynamics and emerging
infectious disease,'
is part of a Philosophical Transactions of the Royal Society B issue
on 'Climate change and vector-borne diseases of humans,' edited by
Paul Parham, a specialist in infectious disease epidemiology at
Imperial College in London."
