Most of the cold air was locked up over the Artic this past winter, whereas normally it is carried south by the jet streams. Some areas of the planet did have record cold in February. An article about February's snow in Baghdad, Iraq (the second snowfall in the last 100 years) says the warm winter in Virginia had to do with the "north atlantic oscillation" [NAO]:
> So why is it that we seem to be in a snow hole?
> Part of it has to do with something called the North Atlantic Oscillation. This combines the effect of two features in the atmosphere; the Icelandic Low and the Azores High. - https://www.wsls.com/weather/2020/02/12/baghdad-sees-rare-snow-our-winter-remains-wimpy/ https://www.wsls.com/weather/2020/02/12/baghdad-sees-rare-sn...
Having just used the "disable javascript to read the article" trick, I noticed this Economist article correctly points out the NAO's influence in keeping cold air locked up in the Arctic, but doesn't mention the snow in Baghdad nor the blizzards in Turkey [0] nor the record colds elsewhere (certain places in Canada, eastern Russia, etc)

I read reports of potato farmers in Idaho having to deal with an early frost last fall, and racing to harvest the potatoes before they were ruined by an early cold snap. I don't know how much of their crops were lost. I've also noticed reports of a sugar shortage.
Humans need to work on being climate-flexible, not being "all in" on global warming.
"A false dilemma (or sometimes called false dichotomy) is a type of informal fallacy in which a statement falsely claims an "either/or" situation, when in fact there is at least one additional logically valid option." -- https://en.wikipedia.org/wiki/False_dilemma https://en.wikipedia.org/wiki/False_dilemma
The false dilemma presented in this article is that of "global warming" vs. "the old climate status quo". The third logically valid option is that climate is now cooling due to the solar cycle. I read a great article about one of the solar telescopes having measured slight changes in the sun's output over the last 20+ years... The data is out there, scientists just have to consider the full spectrum of climate possibilities.
[Edit] I thought the article was about the SOHO satellite, but maybe it was about instruments on the International Space Station. These pages mention European solar observatories on the space station:
> The Sun does not always shine with unchanging power: its output varies minutely over the period of about 11 years known as the ‘solar cycle’. In principle, these fluctuations can affect us on Earth.

> This is where the Solspec instrument comes in. Part of the Solar package on the International Space Station, it was launched with the European Columbus space laboratory in 2008 and tracked the Sun until it was shut down this year [2017]. It measured the energy of each wavelength in absolute terms and its variability – a feat that requires a higher order of precision than relative measurements. As an analogy, it is easy to feel a change in temperature, but nobody on Earth can sense the exact temperature without a thermometer.

An article about February's snow in Baghdad, Iraq (the second snowfall in the last 100 years) The "second" snowfall would mean it wasn't a record. The data showing this winter was the warmest on record as a global average (not just Virginia) takes these outliers into account. Nothing about those events calls the general warming trend into question. >Humans need to work on being climate-flexible, not being "all in" on global warming. No, humans need to accept reality. Carbon dioxide emitted by human activity is warming the planet and that could destabilize parts of the environment that humans rely on. >The third logically valid option is that climate is now cooling due to the solar cycle. This is a joke, right? You said it yourself: the period of the solar cycle is 11 years. It cannot explain a phenomenon that has been observed over more than a century.
- teslabox 7y agoThe bit in my comment about the period of the solar cycle being 11 years was a quote. The sun also oscillates in intensity over hundreds and thousands of years. The sun was (allegedly) slightly less active the Europe's colonial age, which motivated a lot of people to leave Europe. The sun was slightly more active during most of the 20th century, leading to the observations behind the theory of anthropogenic global warming. Some scientists, who aren't wedded to the anthropogenic theory, have looked at all the solar numbers and concluded we're due for a couple decades of weak solar cycles (global cooling) before the warming resumes. I don't know who to believe, I just wanted to point out that there might be a reason behind this alleged "warmest winter ever" other than "it's the CO2". I'm not particularly interested in debating with someone with convictions of hot-earth environmental catastrophe being more reasonable than cold-earth environmental catastrophe, so feel free to have the last word.

You know how many of them accept the scientific consensus that human activity is causing climate change and it's a problem? All of them. >I'm not particularly interested in debating someone with convictions I don't have "convictions". What I have is a degree in physics.
