So I emailed Gavin Schmidt the current top NASA global warming scientist. He is quoted in a mainstream science article stating we currently have 1 degree Celsius increase in warming. So I sent him data stating actually the warming is over 1.5 degree C. already!! He said that was just an arctic anomaly. So I went back to confirm what he told me. Nope it is the global average. So I dig more - what is the discrepancy about? I find a Canadian scientist who says that this 1 degree C is because the mainstream scientists are only using 1951 as their baseline!! So I email back Gavin - no response. So I dig more. Sure enough I find a Scientific American article that states exactly that - NASA uses 1951 as their baseline for global temperature increases even though industrial-based global warming has been going on since coal was introduced in the 1760s. And so I email Gavin about that SciAm article - no response. This is quite shocking.

O.K. so that's a PDF link. I just downloaded it.
It says there should be TWICE as many buoys than currently exist to get accurate Arctic temperature readings - in other words it says we need 60 buoys - not 30.
The magnitude of past abrupt climate change events around the planet may have been underestimated, according to a major international study led by a scientist based at NUI Galway.
“Abrupt climate events that occurred during the last interglacial [warm] period, circa 125,000 years ago, have underestimated [temperature rise] by up to 4 degrees,” said lead author Dr Audrey Morley from NUIG school of geography and archaeology.

The new research suggests that the oceans hundreds of millions of years ago were much cooler than we thought. If true, that means that the global warming we are currently undergoing is unparallelled within the last 100 million years, and far worse than we had previously calculated.

As Natalia Shakhova states - EVERY YEAR COUNTS and could release a Methane Bomb.

free gas has accumulated for hundreds of thousands, or even for a million years. This is why the amount of this gas and its power in releasing (due to its high pressure) is tremendous.
That would allow large releases of methane and whatever you call it - outburst, bomb, or whatever, I see no point to say no to such a possibility. I’m afraid to say yes because we still have to learn so much about the mechanism.
a linear trend becomes exponential.
This edge between it being linear and becoming exponential is very fine and lays between frozen and thawed states of subsea permafrost. This is what we call the turning point. To me, I cannot take the responsibility in saying there is a right point between the linear and exponential yet, but following the logic of our investigation and all the evidence that we accumulated so far, it makes me think that we are very near this point. And in this particular point, each year matters.
This is the big difference between being on the linear trend where hundreds and thousands of years matter, and being on the exponential where each year matters.
the layer of hydrates composes just few hundred of meters – this is a very small fraction compared to thousands of meters of underlying gas-charged sediments in the ESAS.
Dr. Semiletov added that the 5 billion tonnes of methane that is currently in the Earth’s atmosphere represents about one percent of the frozen methane hydrate store in the East Siberian Arctic Shelf. He finishes emphasising “…but we believe the hydrate pool is only a tiny fraction of the total.”
As gas within the sedimentary basins of the ESAS have been accumulating for a million years with no way to be released earlier, the supply for currently occurring emissions is tremendous. Because the shelf area is very shallow (mean depth is less than 50 metres), a fraction of these emissions will reach the atmosphere. The problem is that this fraction would be enough to alter the climate on our planet drastically.
Russian scientists deny climate model of IPCC
Earlier it was believed that the bulk of subsea permafrost in the ESAS is continuous that eliminates the destabilization of a giant pool of lower-laying methane hydrates. According to the model estimates of the Intergovernmental Panel on Climate Change (IPCC), until the end of the 21st century the degradation of permafrost in the ESAS cannot exceed several meters and the formation of through taliks will take hundreds or thousands of years that eliminates the opportunity of massive methane (CH4) emissions from the bottom sediments of the ESAS into water column - atmosphere system due to the destruction of hydrates. Thus the IPCC considers the potential contribution of the ESAS into the emissions of CH4 as insignificant. The paper shows that the model is not really correct.
"In 1982-1983, the Permafrost Research Institute of the Siberian Branch of the Russian Academy of Sciences drilled four wells, and based on this data we found that the rate of vertical underwater permafrost degradation in the area has gone up to 18 centimeters per year (14 centimeters on average) in the past 30 years, which is ten times faster than expected," the press service said.Shakhova interview youtube
A comment: Consider just ONE gigaton, or just one/fiftieth, emitted over just one year. Multiplying one gigaton by 100 would give us 100 gigatons of CO2 equivalent. Adding a 100 gigaton equivalent to our total world CO2 production of 38 gigatons = 138 gigatons of CO2. The CO2 total almost quadruples from just ONE gigaton methane release. Big trouble for Planet Methane.Shakhova interview - (different) the ice was supposed to be 2 meters thick but only 40 centimeters. The methane bomb could release in 5 years - this was in 2013 - 4 years ago!
So GEE's (guy Mcpherson) big point is once the arctic albedo is gone - that's another what? .65 temperature increase - conservatively. Then you have arctic methane - potentially 50 gigatons - another 2 degree temperature increase. Then you have arctic CO2 from permafrost melting.

November 2017 will be remembered not for total Arctic ice extent, which was the third lowest recorded over the period of satellite observations, but for the record low extent in the Chukchi Sea. This is a key area for Arctic Ocean access, and is an indicator of oceanographic influences on sea ice extent.http://nsidc.org/arcticseaicenews/
So that Chukchi Sea is between Alaska and Russia. I'm used to looking at Alaska from the lower 48!! haha. Peter Wadhams on details of how the ice thickness is only half of what is was - and so the area is dramatically dropping -
