But then NASA adjusted the V3 data and called it GHCN V4 “unadjusted”. The chart shown above in my tweet toggles between the prior V3 chart and the “unadjusted” V4. See the difference?
Note how the lack of warming has been removed and now the V4 data show modest warming. The missing heat was found – in the statistics! So in a sense, global warming has been “man-made” – done through statistical fudging and not human activity.

Joe Bastardi explains why this winter has been so mild in the US, but also across N Europe, at CFACT.
1) I will make the case for why such winters like this happen
2) I will point out that nowhere in this article did the massive natural physical drivers that far outweigh the effect of CO2, which is only .041% of the atmosphere. Pointedly, of which man is only responsible for 25% and the US only 15% of that total.
I am not going to waste time attacking here, except to say this kind of one-sided journalism and the fact that nowhere did anyone show what I am about to reveal to you, should raise questions of any objective person.
Basically the rules of the game are, if its warm like this winter, its climate change, if it is cold, its climate change. It is typical of everyone gets a trophy in that any answer even if opposite, means you get credit.
I won’t copy the whole article as it is a bit technical, but it can be seen here. However these are the main points Joe raises, starting with the role of El Nino and water vapour:
Water vapor is by far the most important greenhouse gas when it comes to the planetary weather and climate. Meteorologist look at “saturation mixing ratios” which show a correlation of water vapor to temperature. Basically the colder and drier the air mass, the more the introduction of water vapor will lead higher temperatures, there is no place like the arctic to prove this is the case. The cyclically warmed oceans have put more water vapor (and CO2) into the air. When Super El Niño’s go off, the immense amounts dispersed lead to a step up of the temperature. The colder regions leading the way as will be opined on below.

The COP26 UN climate change conference set to take place in Glasgow in November has been postponed due to COVID-19.
This decision has been taken by the COP Bureau of the UNFCCC (United Nations Framework Convention on Climate Change), with the UK and its Italian partners.
Dates for a rescheduled conference in 2021, hosted in Glasgow by the UK in partnership with Italy, will be set out in due course following further discussion with parties.
In light of the ongoing, worldwide effects of COVID-19, holding an ambitious, inclusive COP26 in November 2020 is no longer possible.
Rescheduling will ensure all parties can focus on the issues to be discussed at this vital conference and allow more time for the necessary preparations to take place. We will continue to work with all involved to increase climate ambition, build resilience and lower emissions.

A study has cemented the link between an intense global warming episode 56 million years ago and volcanism in the North Atlantic, with implications for modern climate change.
Roughly 60 million years ago, circulation changes deep within our planet generated a hot current of rock — the Iceland plume — causing it to rise from the heart of Earth’s mantle.
The Giant’s Causeway in Northern Ireland is a geologic feature consisting of thousands of interlocking basalt columns that formed from volcanic eruptions 60 million years ago.
The Wrong Kind Of Carbon
Although a great deal of North Atlantic volcanism happened close in time to the PETM, scientists were initially skeptical that it could have driven the warming.
Sedimentary layers that formed at the time had the wrong kind of carbon — they were rich in the isotope carbon-12, indicating an organic carbon source rather than a volcanic one.
The leading theory was that fluctuations in Earth’s orbit around the sun melted a type of frozen methane just beneath the seabed called methane clathrates.
Yet scientists found scant evidence that enough clathrates existed in the pre-PETM world, or that they could have melted fast enough to drive the warming.
A possible missing link between the North Atlantic Igneous Province and organic carbon was spotted in 2004 in seismic scans through the seabed off the coast of Norway.
