Wind blown lake ice creeping on shore.  Don't know when this occurred, but its interesting to see ice clink-chattering out of a lake.

Nice little end of show piece on CNN today about early spring in China etc on Christiane Amanpour... ends though with a warning about the confusing being caused to the plants and animals by the changing climate.  Cant see it on line (yet?).

U.S. Heat, February 2017
Warm U.S. Februaries becoming much more common

The Contiguous United States (CONUS) was exceedingly warm east of the Rockies in February 2017. Figure 1 shows monthly mean temperatures up to 6 °C (11°F) above normal. In contrast, the Pacific Northwest was colder than normal. One of the most noteworthy aspects of the persistent February warmth in the U.S. can be seen in the ratio of record high to record low temperatures. According to the National Centers for Environmental Information (NCEI), more than 6,300 record daily highs were tied or broken compared to less than 130 record lows. As a result, February will go down as the 27th month in a row with more record highs than lows. For every low temperature record set there were 49 high temperature records set, the highest such monthly ratio since January 1920. ...

A "warm nose" prevented blizzard conditions along the coastal cities of the U.S. from the big nor'easter that brought copious moisture up from the Gulf of Mexico, in front of record cold from the west and north.  Although areas farther inland are getting hit hard, and moderate flooding and beach erosion occurred along the coast, the big city populations are wondering why #snowmageddon2017 turned into #whatmagedden.

The record warmth this winter, then a sudden hard freeze last week, has caused crop losses aporoaching a billion dollars in South Carolina and Georgia alone.  Severe weather is forecast for later this week.

Widespread damage from Southeast freeze
At least 90 percent of the peach crop in South Carolina (the nation’s top peach producer behind California, with a typical crop value of $90 million) was wiped out by freezing temperatures late last week, according to the state’s agriculture commissioner. The state’s wheat and corn fields also suffered heavy damage, reported WISTV. A less severe freeze in Georgia may have ruined anywhere from 25 to 75 percent of that state’s peach crop. Blueberries across the Southeast also experienced major damage, as summarized by Louisville, KY, broadcast meteorologist John Belski. It dropped to 25°F in Gainesville, FL, on Thursday morning, the coldest reading for so late in the year in more than a century of Gainesville records. Jacksonville’s 28°F was also a record for so late in the year. Update: Total crop losses in South Carolina and Georgia could approach $1 billion, according to an AP report filed Monday afternoon.

Arizona doesn't usually see 90° (32°C) until mid-May.
NWS Tucson:  Another record has fallen, the daily high at Tucson. We hit 93 at 12:57 pm breaking the old record of 92 set in 1997. #azwx

I wonder what is the historical frequency of these kinds of "fake spring" phenomena. How many times a decade these happen per location? Whatever that number is, I bet it is increasing and will keep increasing until it is a common thing. This is of course more marked on the lower northern latitudes and moving Northward. As the winter "heat spells" become longer, more intense and more frequent areas that for millennia were ideal for these perfectly adapted trees will no longer be so.

Of course this will be somewhat mitigated by ideal areas for cultivation being created much further north. Russia and Canada might like that, for however long it may last.
I am an energy reservoir seemingly intent on lowering entropy for self preservation.

Climate change: ‘human fingerprint’ found on global extreme weather

Global warming makes temperature patterns that cause heatwaves, droughts and floods across Europe, north America and Asia more likely, scientists find
...
The new work analysed a type of extreme weather event known to be caused by changes in “planetary waves” – such as California’s ongoing record drought, and recent heatwaves in the US and Russia, as well as severe floods in Pakistan in 2010.

Planetary waves are a pattern of winds, of which the jet stream is a part, that encircle the northern hemisphere in lines that undulate from the tropics to the poles. Normally, the whole wave moves eastwards but, under certain temperature conditions, the wave can halt its movement. This leaves whole regions under the same weather for extended periods, which can turn hot spells into heatwaves and wet weather into floods.

This type of extreme weather event is known to have increased in recent decades. But the new research used observations and climate models to show that the chances of the conditions needed to halt the planetary waves occurring are significantly more likely as a result of global warming.

“Human activity has been suspected of contributing to this pattern before, but now we uncover a clear fingerprint of human activity,” said Prof Michael Mann, at Pennsylvania State University in the US and who led the study published in the journal Scientific Reports.

How Climate Change Covered China in Smog
Air quality in Beijing has a lot to do with snowstorms in Siberia.
...
Something was strange about the smog. Usually smog will dissipate when sources of air pollution—like cars or factories—shut down for a time. But this cloud was stubborn. As part of solar new year celebrations in February 2013, millions of families drove their cars out of Beijing to go on vacation, and the government ordered all factories to cease operations. The smog didn’t subside much, and less than a week later the full-on “airpocalypse” returned as bad as before.

What made the winter smog so bad that year—and in the winters since, which have also been stubbornly smoggy? Two new studies revisit the episode. Both of them argue that climate change will make this kind of smog event much more common. And, remarkably, one of them asserts that the Chinese smog of January 2013 was worsened by two weather phenomena thousands of miles away. Because the Arctic Ocean froze less than it usually does, and because higher-than-usual snowdrifts piled up across the boreal forests of Russia, millions of Chinese people were subjected to some of the worst air pollution ever measured.

That’s because the smog of January 2013 wasn’t the result of emissions alone: Weather played the accomplice. For most of that winter, air over eastern China barely circulated. Trade winds went dormant, so smog could not ventilate to the east; and vertical circulation slowed, meaning particulate matter could not float up into the higher atmosphere. And as is typical for Chinese winters, rain never arrived to wash air pollution out.
...
