The volume of Arctic sea ice is very close to the median over the past 12 years and continues to grow.
There has been no trend in Arctic sea ice extent or volume over the past twelve years.

According to CET, March 2019 was the 17th warmest on record since 1659, 1.2C higher than the 1981-2010 average.
Sound impressed? No, thought not!
The month as a whole actually seemed to be pretty unremarkable. There was some mild weather at the start of the month, accompanied by very wet weather. The last few days were also pleasant and sunny.
But unusually warm?
The graph at the top gives a bit of perspective.
First of all it is obvious that last month was pretty typical of Marchs during the last 30 years or so.
The fact that it is 1.2C above the 30-year average means little, as natural variability means some years are warmer and others cooler, such as last year. That’s what an average is.
Indeed, in the last 30 years, eleven had March anomalies of 1C or more. Six of these years were warmer than this March.
By far the warmest Marchs were in 1957 and 1938, again suggesting that there was nothing unusual about last month.
The other thing which stands out is that most Marchs used to be much colder than normal until the 1980s.

NOAA says last month was “among the eight warmest Februarys on record” in much of the Earth.
According to NCEI’s Regional Analysis, South America, Europe and Oceania had a February temperature that ranked among the eight warmest Februarys on record.
There is no such word as “Februarys” – plural for February is Februaries. But besides the fact they are illiterate, they are also lying
It looks like the world is burning up, with just a few slightly cool areas. It has an official government seal on it, so it must be accurate, right?
The map below shows where NOAA actually had surface temperatures in February.

As I reported last September, Greenland’s ice sheet mass balance had grown at close to record levels for the second year running.
To clarify again, the mass balance calculation accounts for:
2) Ice melt
In other words, it does not include calving.

“El Niño conditions across the equatorial Pacific have come together, and we can now announce its arrival,” said Mike Halpert, deputy director, NOAA’s Climate Prediction Center, and ENSO forecaster.
NOAA gives a 55% chance of El Niño conditions persisting through the spring.
Sea surface temperatures in January — orange-red colors are above normal.
“While sea surface temperatures are above average, current observations and climate models indicate that this El Niño will be weak, meaning we do not expect significant global impacts through the remainder of winter and into the spring,” Halpert said.

February is not over, and Arctic sea-ice extent is already over half a million square kilometers higher than last year at this day.
The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous four years and six out of the last 14 years.
Arctic sea-ice has stubbornly resisted the very warm years between 2015-2017 caused by the big El Niño. Are we going to see an increase in Arctic sea-ice over the next few years? Only time will tell, but the idea cannot be discarded.

A “Siberian Express” weather disturbance currently crossing the Arctic Ocean will meet up with the semi-permanent winter “polar vortex” over Canada, pushing a record-breaking cold air mass into the Upper Plains and Midwest U.S. by Wednesday.
Chicago All-Time Record Low?
Both the European (ECMWF) and U.S. (GFS) weather forecast models are in agreement that by Wednesday morning temperatures in the Chicago suburbs will be approaching -30 deg. F. The all-time official record low for the Chicago metro area was -27 deg. F (O’Hare) on January 20, 1985, and that 34 year old record could fall as the ECMWF model is forecasting -32 deg. F for Thursday morning while the GFS model is bottoming out at -26 deg. F on Wednesday morning. Of course, these forecasts will change somewhat in the coming days as the cold wave approaches.

In late 2018, there were some predictions that there would be a significant El Niño event in 2019. There were strong hints of an El Niño event in both SST data and forecasts. In an April 6th 2018 essay, Bob Tisdale suggested “Looks like one may be forming right now.”
But if we look at the animation provided by NOAA’s Climate prediction center, it sure looks like it has been fading:
