Just think. IF the tundra thaws that will give us more agricultural land.

"Russian permafrost expert slaps down AGW

In the video a German journalist travels to Siberia and speaks with Russian permafrost expert Michali Grigoryev on the state of the permafrost (2007). Grigoryev shows the journalist a rare baby mammoth uncovered from the ice, and adds that such finds are becoming more and more frequent today. “Because of climate change”, the journalist asks at the 0:48 mark? Grigoryev answers:

    No, you are wrong. The permafrost is not melting. There is no man-made climate change.”

The journalist then quotes the Russian scientist:

   " Indeed above at the surface it has gotten warmer, but that’s just part of a normal cycle. The permafrost is rock hard, And that is how it is going to stay. There’s no talk of thawing.” "

"At the 1:24 mark, the scientist says:

    "The cyclic warming is coming to an end. It is going to get colder soon. The climate depends on the sun and the oceans. Three factors have coincided and have warmed the climate, but in 8 to 15 years, it’s going to be colder again.” "

Gee those Russian scientists must be real dumb. You better write to them quick and point out the error of their ways.

So did you read up on Michali Grigoryev? Or just decide to shoot the messenger. Grin Grin Grin Grin Grin

I read you scientific sources where they claim 3mm SLR using satellite altimeters that have an accuracy  of 34mm.

Or perhaps you would like this study? -

"Relative to the past 2,000 years1,2, the Arctic region has warmed significantly over the past few decades. However, the evolution of Arctic temperatures during the rest of the Holocene is less clear. Proxy reconstructions, suggest a long-term cooling trend throughout the mid- to late Holocene3,4,5, whereas climate model simulations show only minor changes or even warming6,7,8. Here we present a record of the oxygen isotope composition of permafrost ice wedges from the Lena River Delta in the Siberian Arctic. The isotope values, which reflect winter season temperatures, became progressively more enriched over the past 7,000 years, reaching unprecedented levels in the past five decades. This warming trend during the mid- to late Holocene is in opposition to the cooling seen in other proxy records3,5,9. However, most of these existing proxy records are biased towards summer temperatures."

Bugger. only warming for 7,000 years.

Study warns of looming potential for runaway global warming
BY MAX GREENWOOD - 08/06/18 07:56 PM EDT

A new study out Monday warns of the possibility of out-of-control global warming if humans fail to band together to fight the worst effects of climate change.

The analysis, conducted by researchers at the Australian National University and the Stockholm Resilience Center, among other institutions, outlines the potential for a "threshold" that, if crossed, would lead to runaway warming patterns and the advent of a "Hothouse Earth."

If such a threshold is crossed, the study warns, global average temperatures could climb as much as 8 degrees Fahrenheit above current temperatures and sea levels could rise 30 to 200 feet.

"Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene," the study says.

The report is based on a review of past research of thresholds for climate change, according to USA Today.

Even if every country that signed on to the Paris climate agreement meets its obligations under the pact and limits the global temperature increase to 3.6 degrees Fahrenheit, runaway global warming could still be a threat, the newspaper reports. ...



If dangerous perhapses could be taken seriously....
And the prediction of "30 to 200 feet" tells me they are guessing wildly.

Seeing as there is no data in the paper merely assumption that is correct. They don't even quote any Representative Concentration Pathways (RCP's).

The uneducated never do understand the uncertainty scientists use in their language—doesn’t mean they are not confident of their results and conclusions.

yes. So much easier to be confident of your results and conclusions when you don't use data.

So you are uneducated too?

You prefer Nostradamus to scientific prediction?

Doesn’t matter how much data is used as a basis for prediction, if you make a prediction Lees calls you “Nostradumbarse” which, in his mind, excuses his lack of education.

Both poles are melting, permafrost is thawing—clearly the globe is warming.

Both poles (Greenland and Antarctica) melting, sea level rise is accelerating—predicting more sea level rise is a very sure bet. How much of a rise—bit less certain.

All this properly expressed.

Will this affect you? If you are 60+, not too much, I suppose, unless you are a farmer, live surrounded by bush or on the very coast. Will it affect your kids and grand kids? You betcha bippy!

But take the coward’s way out, like Lees and Booby are doing, pretend everything is fine. A man does not take the cowardly way.

You ignore the paper on increase in ice mass in Antarctica AGAIN. Permafrost is reported to have been warming for 7,000 years. That is way before AGW.

Yes. So you keep saying. Antarctic is not melting. Repetition won't make it so. SLR - based on satellite altimeters with errors 10 times the supposed accelerated rate.

you mean like ocean temperatures in zeta-joules?

And yet other scientists disagree with you assessment. Why is that?

Here we go off into the wild blue future. Making assumptions most climate scientists refute.

No. Just not taking the alarmist approach.

I posted a graph of oceanic heat content.

There are tons of data about AGW, SST, land temperatures, Jet Stream weakening and melting of polar ice.

No data?  Roll Eyes

BUT

forecasting climate, ocean heating, polar ice melting etc is difficult:

1. HM La Ninas, El Ninos, ENSO neutral years will there be?

2. What will the PDO, ADO, IDO (Pacific, Atlantic and Indian Ocean Decadal Oscillations) and the Arctic DO do over the forecast period?

3. Pattern of carbon pollution? Aerosols? Volcanic eruptions adding more aerosols? Impossible to predict volcanoes and volcanoes create bits of cooling by sending aerosols to top of atmosphere where they reflect some of the sunlight. What if some countries or a new RE technology was introduced? EVs becoming popular, what about hydrogen etc etc etc

4. The sun—it went a tiny bit quiet in the 1980s, when will it resume normal activity, bumping up the warming a bit? Bit of a wildcard, eh?

Most here would struggle to predict a race on the weekend, how would they go predicting a race to be held in 12 months time? What horses? You are the one predicting the race!
