The polar vortex is a winter phenomena. It develops as the sun sets over the
polar region and temperatures cool. During the spring, the sun rises and the
absorption of solar radiation by ozone begins to heat the polar stratosphere.
This heating eventually causes the vortex to disappear along with the polar
night jet. However, this process is helped along by planetary-scale waves that
propagate up from the troposphere. This wave event that drives the vortex
breakup (or final warming) acts to also increase the temperature of the polar
region and ozone levels. Source NASA. Other causes include cfcs chlorine, and
ozone levels. NASA says it is an annual event with highly variable outcomes
year to year. There is also a polar vortex at the south pole.
But the last time we had the effects of the Polar Vortex a couple of decades
ago, James Hansen said the polar vortex displacement was caused by global
cooling. It is counter intuitive not to question. From reading other articles it
has been stated the cause of the polar vortex displacement is not really
understood. The claim that it is is so much alarmist talking points.I don't understand how your reference and put down of others view points
as "for some of the less developed minds here" does not get censored as
being a personal and belittling attack.
What exciting news... WE DID IT, praise the EPA for policy's that have
saved humanity. let us all unite with joy knowing that the future is safer
from the better world we have created, Mother Earth is healing herself.
Thid BarkerPlease understand that one reason for no calamities is
because the media tend to give voice to the extremes (either “the world
will end” or “absolutely nothing will happen”). Moderate data
guys telling us that we will have slow but inexorable negatives just
aren’t press worthy.I think we first need to dial down all the
noise and rhetoric and deal with the science. One reason we have not is because
(I think) we intrinsically know that this will not be an easy or cheap fix. But
we need to answer the questions of what is happening and (understanding these
will be estimates) at what speed are we moving? Only once we have these firmly
in hand should we bring in the economists to help us map out a strategy.Will other countries cheat? When is that not true? But will anyone
move without leadership from the world’s largest economy? No.BTW, the Carbon Tax and Carbon Trading were conservative ideas on how to avoid
govt. regulation and allow the govt. to simply set overall limits and then let
the markets sort out the particulars. Funny how these things morph.
The polar vortex displacement is actually caused by global warming. It may seem
counterintuitive to some of the less developed minds here, but it is true.
Twin lights. I don't disagree with much of what you said. However, entered
into this global warming debate is the proposed "fix" of massive carbon
taxes. When other people's money, politics and science (real or
theoretical) all come together, watch out for a massive scam! Whether you
believe that or not, even IF (huge if) carbon taxes would change the climate,
the reality is that China, India, Russia and most other real polluters will not
be joining the "fix" and that renders the "fix" useless and
irrelevant, even economically destructive. In other words, we and they are not
experiencing the disastrous climate changes that some in science and politicians
predicted. That means ever fewer countries will risk their economies to support
a huge scam which is what we and they are actually experiencing! Currently it
appears the only countries pushing this world wide carbon tax are countries that
believe we will be giving them our money (which we don't have anyway). Go
It is a pity the article didn’t mention what is happening to the Arctic
VortexDim Coumou, a senior scientist at the Potsdam Institute for
Climate Impact Research recently said the polar vortex is driven by the
difference in temperature between the Arctic and mid latitudes.Once
sharp, this differential has blurred recently as the Arctic - where temperatures
are rising at about twice the global average - warms up. When the vortex
weakens, the air starts heading southwards, bringing exceptional snow and chill
to middle latitudes.The strong meanderings of the
“Jet-stream” that contains the Arctic Vortex is still not fully
settled, but it's clear that the Arctic has been warming rapidly. Last month, European scientists reported that the volume of sea ice in
November was about 50% greater compared with a year earlier, following a
recovery in the Arctic summer. Despite this bounce-back, sea-ice remains at
near-record lows and its overall trend is one of retreat, they said.Sharrona - “Antarctica has been adding ice all along.” Sorry
only the Eastern Antarctic is having increased Sea-ice. However, the regions of
West Antarctic are recording a drop in sea-ice extent of about 7% each decade.
In 1988 Ted Danson hit the environmental scene predicting that the oceans would
be dead in ten years and the remainder of the Earth would follow. The more he
made a big deal out of it, the greater his following. The news media was
frontpaging fast. Just six years ago Al Gore predicted that all sea
ice would be gone by 2013. He’s off by a scant 920,000 square miles. In
just the first 7 ½ months of 2013 the Arctic Ice Cap added more than 19,000
Manhattans. Oh, and Antarctica has been adding ice all along.
Thid Barker,As a biology major you know how science advances. There
are likely things you were taught that have since been replaced by more accurate
theories. But (unless you are dramatically older than me) some of the
particulars have changed but most of the basics remain.Climate
science is a younger science. But a science it is. Most of the full-throated
deniers seem to believe in a web of conspiracy and intrigue that defy simple
human experience (nobody keeps a secret and lots of folks want to be the heroic
whistleblower).I suppose the scientists who taught you would be
quite peeved if anyone questioned their bonafides the way climate scientists are
routinely challenged. And there are those who offer very well-known information
as something the scientists have failed to consider (cue the little ice age).
Imagine telling your profs about natural selection as if they had not heard? As to the models. They will always be improving. Climate is an
exceedingly complex thing to model and we will likely only get reasonable
approximations. They will not predict any one year but will give us the long
Twin lights. As a biology major let me suggest that any "scientist" that
tells you he has the final word on anything, you can know for a certainty that
he is no scientist. And that especially is true about climate change. Experience is not science but it is still valuable knowledge and the record
cold temperatures we are experiencing is more real and observable than all the
theoretical computer model forecasting in the world. We are not experiencing
what science has forecast! How come? Because science got it wrong as they
usually do, at least at first!
Global warming theory never claims there won't be any record lows, it just
says they'll occur less often on average. Think of it this way, if your
part of the world has had a 1C warming trend the past century then all the ups
and downs we see with weather during the year are still going to happen,
it's just going to roughly be 1C warmer every day due to global warming.
That means more record highs than record lows, something we've seen in the
Thid Barker,Not quite. There will be greater and greater accuracy
as science progresses. It is not that what we once knew is proven completely
wrong - Einsteinian physics did not disprove Newtonian physics - it gave it a
more nuanced view that was more applicable at the extremes.Look to
early leaders of the church. They loved science. Look to leaders today. Many
come from the worlds of education or science.Science is the best way
we have of understanding the world in front of us. Yes, the scriptures teach us
who we are and our purpose but they not to give us the nuts and bolts of how to
solve our day to day problems (principles yes, data no). For that we use the
best information available and that is from science.Will science
continue to advance? I sure hope so. Will some things be proven wrong?
Likely. Will most of what we know turn out to be completely wrong or simply
more refined? The latter.
@ Twin lights. Science is so fleeting. Everything we think we know will
eventually be proven to be completely wrong or at least very incomplete. As our
grandparents science is to us, so will our science be to our grandchildren.
The only thing that matters is planet wide data over the long term. All else is
fluff and "I told you so". Let's leave science to the scientists.
Yes liberals we know, there is a difference between climate and weatherWhen there are record high temps its climateWhen there are record
low temps is weather
Dang it! And just when many were convinced man made global warming (climate
change)is real! Dang it anyway! Pretty much spoils the climate change, carbon
tax party doesn't it?
