I am much more curious what caused a "stable" climate in the last era in an ever changing chaotic structure of nature and existence then why it is getting unstable again. But that is just me being a Dumbass.

There are two jet streams in each hemisphere. The polar jet is the one most are familiar with, it resides mainly at higher latitudes. There is also the subtropical jet, it resides at lower latitudes.

The locations of the jet streams are determined by the convergence of large air masses of different temperatures. The polar jet forms where the cold polar airmass meets the warmer temperate airmass. The subtropical jet forms where the warm temperature airmass meets the warmer tropical airmass. These large airmasses vary in extent and location, as they change shape the location of the jet streams change. It is possible that, as the Arctic warms, the polar jet will migrate more northward.

But the wind simulation which created the brouhaha does not show a jet stream crossing the equator, it shows high altitude winds being affected by upper level pressure differences, just as surface winds are. Air moving from a high pressure area north of the equator to a low pressure area south of it, that's all. It shows nothing particularly abnormal. This is, once again, a case of someone not understanding what the simulation actually shows.


Paul Beckwith should not be relied upon for his opinions on climatology. He is indeed, somewhat of an alarmist.

What part of chaotic and no longer predictable and what that means about the effects it may have on our planet and all life on it and how we no longer know what it's going to be for a day/week/year/decade/century do some people just not get?

Have you seen some of the crazy highs in the ME and India and the US in May and June? And the crazy snows? Unpredictable. Nothing to fear but hell people, let us prepare.

What is your opinion on Robert Scribbler, the man that wrote the piece referenced in the OP's link?

Climate change...climate change.

Of COURSE the climate changes. It changes all the time, and has changed again and again throughout the history of this planet.

We've had ice ages and droughts and temperature fluctuations up the wazoo.......the planet's gonna do what the planet does. What everybody (at least the eco-freaks) are going into a frenzy over is what if climate change causes the extinction of the human species. (If it does, life will still go on, the earth will still keep turning and climate will continue to change. We just won't be here to watch it.)

The thing about climate change... is that most of the data is based on the weather patterns we've observed for maybe the last 150 years, tops.

We haven't been measuring weather on a global scale long enough to know what the "norm" is for a cycle that could go through changes for thousands of years at a time.

There are plenty of recordings throughout history of unseasonable highs and lows, droughts, famines, desiccation and changes to the trade winds. To think we know it all is just hubris.



if you really care, look into the berkely earth project. they go back 250 years. Really good info if you can let the data inform your conclusion

BEP

If we all promise to write these guys a fat check every month will they STFU about this already?

Are we scared enough yet?

Given, as another poster pointed out, that we've only been able to monitor this since the end of WWII, how on earth do they know that this is "unprecedented" and has never, ever happened before in all of earth's history?

Given the length of time that we've been monitoring this and the amount of time humans have been on the planet, I find it unlikely. Given the length of time we've been monitoring this and length of time life has been on earth, I find it even more unlikely. Given the length of time we've been monitoring this and the length of earth's history ... yeah, I think you know where this is going.


You're standing in a dense forest, and suddenly you see a huge wall of flame speeding towards you. "Oh wow that's a HUGE fire, I should do something." you say. Suddenly, someone comes up behind you and says "Naww, fires happen all the time in forests, don't worry about it. Stay right where you are."

Just because at some point in the Earth's history massive climate change has occurred, and it may possibly be occurring again, doesn't mean it's all hunky dory.

But I'm sure when deserts are tundras, and cities are turned to frozen rubble, we'll still be fine.

Top science groups tell climate change doubters in Congress to knock it off

In a letter dated Tuesday, 31 leading U.S. scientific organizations sent members of Congress a no-nonsense message that human-caused climate change is real, poses risks to society and is backed by overwhelming evidence.

“Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research concludes that the greenhouse gases emitted by human activities are the primary driver,” the letter states. “This conclusion is based on multiple independent lines of evidence and the vast body of peer-reviewed science.”

The effort to draft the letter was spearheaded by the American Association for the Advancement of Science (AAAS), whose leader, Rush Holt — a former member of Congress, vigorously promoted its message.

“Climate change is real and happening now, and the United States urgently needs to reduce greenhouse gas emissions,” said Holt, who was the U.S. representative for New Jersey’s 12th congressional district from 1999 to 2015. “We must not delay, ignore the evidence, or be fearful of the challenge.”

My understanding is the Jet Stream can dip and wind all over the place. Conveniently, this global warming 'thing' is in the stratosphere, so the average layperson can't see it for themselves, they just have to take it at face value. See how they did that?

Theres your sign.


The average layperson probably can't see it but since my job keeps me in the stratosphere for thousands of hours a year, I can see it. The jetstream has most certainly changed. The howling winter westerlies in the mid latitudes this past winter were much calmer than normal. And all of our performance charts are based what is called ISA, or standard temperature and pressures for each altitude. It's been warmer than normal. Since the speed of sound varies with temperature and since our cruise speed is set at a percentage of Mach, our schedules are screwed. It works out to be a change of about 1 knot per degree of temperature increase. Doesn't sound like much but we're burning about a gallon per second, so every second counts. And on a 14 hour flight a couple of knots matters.

This is nothing new. The Earth's weather patterns have been changing like this for billions of years. Scientists ARE clueless because they can't put this together. All it takes is a little common sense. Humans were designed to adapt. These scientists are funded by the government to find the answers the government is looking for, otherwise they lose funding. Nothing will happen that we can't handle. You're too sensitive if someone not buying into this as a population and planet killer frightens you.

Something will definitely happen if we don't do something. We will run out of resources and destroy the habitat which of coarse effects climate.

www.scientificamerican.com...

It's not just the gasses we are putting up its a sum of all the population using and extracting resources and population footprint.

Unfortunately all the fair trade coffee in the world hasn't made a dent on deforestation in South America.

Very true... If it's colder than normal, global warming. If it's hotter than normal, global warming. If there are more storms than usual, global warming, if there are less storms than usual, global warming. If you don't buy into the contradictions, DENIER!!!!!

And if you don't understand why the "contradictions" are not contradictions? What then?

Scientists are clueless



LOL Every single scientist ever is clueless? Interesting. Wonder where medical progress, computers, modern surgery, moon landings, space program, smart phones, GPS...Chemistry, Biology...Where did all that come from. God I suppose. Our scientists were/are much too stupid to contribue to humanity in any meaningful way, eh? LOL


Pretty sure he was talking about climate scientists.

sigh.

I am amazed at how many thinks scientist are completely retarded and are only being scientist because of funding
....

Thousands and more thousands of scientist are simply just scientist doing their job, and they know what they are doing..

There's nothing 'sensitive' going on here. You say all it takes is common sense. I suppose. But not as an argument against science. I'm going out on a limb and guessing you're not a climatologist either. So again, you're relying on other peoples facts to form your opinion.

This is almost like the bible; you cant cherry pick belief( i mean you can, but it illuminates my point). If you're paying attention to scientists for things like safety regulations in cars, or your dr when you go in for surgery, then shouldn't you maybe be paying attention to climate change as well?

Ill rely on the scientists... you can rely on...?

Difference being that in one case, we know what a roaring fire is and what it does, and in this one, we don't know what this is or what it does only what we think it might do.

Basically, his prediction is a prophecy at this point.
