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.

In a report generating substantial media attention this month, the National Oceanic and Atmospheric Administration (NOAA) claimed January 2020 was the hottest January on record. In reality, the claim relies on substantial speculation, dubious reporting methods, and a large, very suspicious, extremely warm reported heat patch covering most of Russia.
The January 2020 Climate Assessment Report, released by NOAA’s National Center for Environmental Information (NCEI), was accompanied by a map showing a giant red menace of extraordinary asserted warmth extending from the Russian border with Poland well into Siberia. Yet, the asserted hot spot appears nowhere else.

A leading climatologist has said that the computer simulations that are used to predict global warming are failing on a key measure of the climate today and cannot be trusted.
Speaking to a meeting in the Palace of Westminster in London, Professor John Christy of the University of Alabama in Huntsville told MPs and peers that almost all climate models have predicted rapid warming at high altitudes in the tropics:
A paper outlining Dr. Christy’s key findings is published today by the Global Warming Policy Foundation.

Canada’s CBC here recently cited “a leaked report” which claimed Canada is “warming at twice the global rate.”
According to the “leaked report”, Canada’s annual average temperature over land has warmed 1.7 C when looking at the data since 1948. But that claim is misleading when recent data is considered.
Over the past 25 years, since scientists began to warn that the planet was warming in earnest, there has not been any warming when one looks at the untampered data provided by the Japan meteorology Agency (JMA) that were measured by 9 different stations across Canada. These 9 stations have the data dating back to around 1983 or 1986, so I used their datasats.
Looking at the JMA database and plotting the stations with longer term recording, we have the following chart:

Le climat peut changer, comme il l’a toujours fait et continuera à le faire sous l’action de variables naturelles. Les activités humaines peuvent-elles avoir une influence comme le prétend la théorie du réchauffement climatique d’origine anthropique ? Cette théorie est basée sur l’existence d’un hypothétique effet de serre défini comme un phénomène radiatifcausé par des gaz tels la vapeur d’eau ou le CO2 qui absorbent une fraction du rayonnement infrarouge émis par la Terre et le réémettent ensuite dans toutes les directions et notamment vers la surface terrestre dont la température serait, de ce fait, plus élevée qu’en l’absence de gaz absorbant l’infrarouge. L’effet de serre résulterait donc essentiellement de l’émission par les molécules de CO2 d’un rayonnement de fluorescence dans le domaine infrarouge . Cette définition est claire et scientifiquement valable car conforme au principe de réfutabilité défini par Karl Popper. Nous l’examinerons à la lumière de théories physiques bien établies et de faits expérimentaux connus.

Our sun was also very sub-normally active in December last year. We are writing the 121st month since the beginning of cycle number 24, in December 2008, and since 2012 (when we started the blog here) we could only reformulate the opening sentence once: In September 2017 when the sun was 13% more active than the long-term (since 1755) average.
All other months were below average. With the sunspot number (SSN) of 3.1 for the monthly average for December and a total of 24 days without any spot (throughout the second half of the month the sun was spotless) we are in the middle of the cycle minimum.
Fig. 2: The sunspot activity of our sun since cycle 1 (1755). The numbers are calculated by adding the monthly differences with respect to the mean (blue in Fig.1) up to the current cycle month 121.

I wanted to expand upon something that was mentioned in yesterday’s blog post about the recent Cheng et al. paper which was widely reported with headlines suggesting a newer estimate of the rate of ocean warming is 40% higher than old estimates from the IPCC AR5 report in 2013. I demonstrated that the new dataset was only only 11% warmer when compared to the AR5 best estimate of ocean warming during 1971-2010.
The point I want to reemphasize today is the huge range in ocean warming between the 33 models included in that study. Here’s a plot based upon data from Cheng’s website which, for the period in question (1971-2010) shows a factor of 8 range between the model with the least ocean warming and the model with the most warming, based upon linear trends fitted to the model curves:
Yearly ocean heat content (OHC) changes since 1971 in 33 models versus the recent Cheng reanalysis of XBT and Argo ocean temperature data for the surface to 2,000m layer. The vertical scale is in both ZettaJoules (10^21 Joules) and in deg. C (assuming an ocean area of 3.6 x 10^14 m^2). The Cheng et al. confidence interval has been inflated by 1.43 to account for the difference between the surface area of the Earth (Cheng et al. usage) and the actual ocean surface area.

Note how the PETM (55 Ma) is about as far from a CO2 analog to modern times as it possibly could be… unless the PETM stomata data are correct, in which case AGW is even more insignificant than previously thought.
Regarding temperatures, the PETM is also about as far from being an analog to modern times as it possibly could be.
Figure 2. High latitude SST (°C) From benthic foram δ18O. Funny how the PETM is often cited as a nightmarish version of a real-world RCP8.5… While the warmer EECO is a climatic optimum. (Zachos et al., 2001). Note: Older is to the right.

There are a number of statements in Cheng et al. (2019) ‘How fast are the oceans warming’, (‘the paper’) that appear to be mistaken and/or potentially misleading. My analysis of these issues is followed by a reply from the paper’s authors.
Contrary to what the paper indicates:
Contemporary estimates of the trend in 0–2000 m depth ocean heat content over 1971–2010 are closely in line with that assessed in the IPCC AR5 report five years ago
Contemporary estimates of the trend in 0–2000 m depth ocean heat content over 2005–2017 are significantly (> 95% probability) smaller than the mean CMIP5 model simulation trend.

Clearly the whole study is worthless, and the paper should be withdrawn.
There are some alarming facts about all of this:
1) Why did the researchers not suspect that the temperature data looked hopelessly wrong at the outset?
2) Why did peer review not do the basic checks that I did?
3) The study carries out some mindbendingly complex statistical analysis, linking arthropod decline to rising temperatures. But how can this analysis have been robust, when the temperature data was hopelessly wrong?
The conclusion is that the faulty temperature data matched the researchers’ expectations of climate warming, and consequently they never bothered to crosscheck. It would after all have been extremely simple to have asked the people who maintain the data.
Whether or not arthropods are in decline I have no idea. But by blaming non existent climate warming, there is a very real danger that the true cause is being missed. Indeed, looking at those graphs, it may well be climate cooling that is responsible.
I plan to contact PNAS, who published the paper, to request that it be withdrawn.

Summary:The recently reported upward adjustment in the 1971-2010 Ocean Heat Content (OHC) increase compared to the last official estimate from the IPCC is actually 11%, not 40%. The 40% increase turns out to be relative to the average of various OHC estimates the IPCC addressed in their 2013 report, most of which were rejected. Curiously, the new estimate is almost identical to the average of 33 CMIP climate models, yet the models themselves range over a factor of 8 in their rates of ocean warming. Also curious is the warmth-enhancing nature of temperature adjustments over the years from surface thermometers, radiosondes, satellites, and now ocean heat content, with virtually all data adjustments leading to more warming rather than less.

Scientists behind a headline-grabbing climate study admitted they “really muffed” their paper.
Their study claimed to find 60 percent more warming in the oceans, but that was based on math errors.
The errors were initially spotted by scientist Nic Lewis, who called them “serious (but surely inadvertent) errors.”
The scientists behind a headline-grabbing global warming study did something that seems all too rare these days — they admitted to making mistakes and thanked the researcher, a global warming skeptic, who pointed them out.
“When we were confronted with his insight it became immediately clear there was an issue there,” study co-author Ralph Keeling told The San Diego Union-Tribune on Tuesday.
Their study, published in October, used a new method of measuring ocean heat uptake and found the oceans had absorbed 60 more heat than previously thought. Many news outlets relayed the findings, but independent scientist Nic Lewis quickly found problems with the study.
Keeling, a scientist at the Scripps Institution of Oceanography, owned up to the mistake and thanked Lewis for finding it. Keeling and his co-authors submitted a correction to the journal Nature. (RELATED: Headline-Grabbing Global Warming Study Suffers From A Major Math Error)…

As the Earth rotates on its own axis, one-half of the Earth is cooling while the other half is warming up.
So the Earth is warming and cooling daily and the temperature is changing 3,600 times every hour in every location all over the world, as there are 3,600 seconds in every hour.
As the Earth is traveling around the Sun in an ellipse at 66,000 miles per hour and is tilted and wobbling as it spins, so the Earth has seasons, as the angle to the Sun varies.
So the temperatures in the spring and summer are usually warmer than in the autumn and winter when temperatures decline.
So there is a massive number of different temperatures over the whole Earth, constantly changing and always in flux.

Wind power is booming in the United States.
It’s expanded 35-fold since 2000 and now provides 8% of the nation’s electricity. The US Department of Energy expects wind turbine capacity to more than quadruple again by 2050.
But a new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems.
Wind power reduces emissions while causing climatic impacts such as warmer temperatures
Warming effect strongest at night when temperatures increase with height
Nighttime warming effect observed at 28 operational US wind farms
Wind’s warming can exceed avoided warming from reduced emissions for a century
