Record-low temperature of -20°C in Slovenia as multiple century-old extreme cold records broken across Europe

COLD
Many areas in Slovenia reached their coldest April morning over the last 100 years! The official meteorological station Nova vas na Blokah peaked at -20.6 °C which has set a new all-time national record for the month of April since the records began. Numerous extreme cold records also across other parts of central and western Europe, deep freeze and morning frosts have been destructive.

As we expected, the weather models were not wrong this time. An unpreceded extreme cold has verified across many parts of Europe this Wednesday morning, following the significant and historic snow a day before. Snowfall with some accumulation was reported even at the seaside in Slovenia and Croatia islands (Kvarner area).

In Slovenia, the weather station Nova vas na Blokah hit -20.6 °C and set the new official lowest temperature for April (the previous record at the station Nova vas was -18.0 °C set on April 4th, 1970). There was another record of -26.1 °C recorded with an unofficial weather station in the village Retje near Loški Potok.


Comment: The amazing thing isn't even the record cold - it's the flip from record heat to record cold in just 6 days!

Alaska DOT: Epic avalanche cascade shuts down Hatcher Pass Road for days

Avalanche debris covers two stretches of the Hatcher Pass Road after last weekend’s storm.

Avalanche debris covers two stretches of the Hatcher Pass Road after last weekend’s storm.
A rare cascade of avalanches over the weekend has shut down the Hatcher Pass Road, and it will remain closed for several days as crews wait for conditions to stabilize before clearing avalanche debris.

Forecasters with the Hatcher Pass Avalanche Center say that five different avalanches crossed the upper stretch of the road, and one of those extended so far that it hit a second, lower stretch of the road, beneath a switchback. The center, in a Facebook post, said that was the first time such a slide had taken place since the 1980s.

Photos posted by the center show ribbons of avalanche debris covering the upper stretch of the road in several areas, as well as massive piles of snow burying large stretches of Archangel Road, which is groomed for skiing and walking during the winter.

A skier from Alberta has died in an avalanche while he and another skier were on a mountain in Banff National Park.

Parks Canada says two male skiers from Canmore, Alta., were on the northeast face of Haddo Peak in the Lake Louise area on Monday when the avalanche was triggered.

Temperatures in UK plunge to -6C as Arctic blast strikes - more snow forecast

UK cold spell

There will be frost, snow and ice in places
Brits are bracing for another bitterly cold day with warnings of more snow as well as bouts of rain as Arctic winds continues to sweep the nation.

Up to 3cm of snow is predicted to fall in parts of Scotland while the mercury is likely to drop to sub zero temperatures again on Wednesday.

Lows of -6C will hit central parts of England this morning and forecasters warned that it will be 'a cold start for all of us.'

It comes after temperatures plunged as low as minus 4.2C overnight in parts of the UK, while some regions had 11cm of snow fall.

Today, a yellow weather warning for snow remains in place for parts of northern Scotland until 10am.

The severe weather warning states that 'snow showers may lead to some transport disruption' in the affected regions, with up to 3cm set to fall.

London is set to record the coldest start to April in eight years, after St James's Park saw the coldest average over the first six days of the month back in 2013, the Star reports.

The Yukon phenomenon: record Whitehorse snow nearly 300% of normal

snow
Even taking into account the city's Arctic locale, this past winter was epically snowy for the Yukon capital.

It snowed before Halloween, and it never really stopped snowing.

As of April 5th, there's 70 cm of snow on the ground across Whitehorse, Yukon; for the city of 25,000, it's a tremendous amount - the most on record for April 4th.

For reference, the snowpack usually peaks around 30 cm of snow, and by late April, the snow base remarkably diminishes to near zero. The sheer resiliency of the Yukon snowpack is quite peculiar.

Alaska snowstorm dumps up to 3 feet of snow, strands 5 people on North America's tallest peak

SNOW
Five people had to ski through a heavy Alaska snowstorm to a mountain chalet after abandoning their airplanes on a glacier on North America's tallest peak, where they were stranded for the weekend, officials said Monday.

The five landed Friday in three separate small airplanes — a Cessna 180 and two Piper PA18s — on Ruth Glacier on Denali, said Maureen Gualtieri, a spokesperson for Denali National Park and Preserve.

A fast-moving storm prevented them from flying off the glacier, and they spent Friday night in their airplanes at about 4,500 feet. They woke up Saturday and realized they didn't have enough resources to ride out the storm.

"That's when they called for help," Gualtieri said.

UAH global temperature drops below 30-year baseline - Earth is cooling

UAH graph
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for March, 2021 has come in at -0.01 deg. C below the 30-year baseline, down from the February, 2021 value of +0.20 deg. C, and down substantially (approx. 0.6C deg. C) from where we were around a year ago.

A continuation of this downward plunge is highly probable over the coming months (with the odd bump along the way-climate is cyclic after all) as low solar activity and La Nina conditions persist.

According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1983:

Historic Arctic cold blast hits Europe: Damaging frost and snow expected across most of continent

extreme cold april europe 2021
An exceptional, more than 100 mbar pressure difference between Greenland and northern Europe on Sunday has released a massive Arctic cold blast towards continental Europe. The sharp Arctic front is racing south and will result in intense snow with blizzard conditions across Slovenia and Croatia on Tuesday. Then, destructive and widespread frost to vulnerable vegetation is expected across central Europe.

A very dramatic weather pattern change is underway this Easter Monday as a deep Arctic cold-core is moving south across western and northern Europe. The first impact is over the UK and Ireland, then the core will spread towards central Europe and the Mediterranean tonight into mid-week days.

100 years later, the Scientific American reversal on CO2

In 1920, Scientific American reported that the atmosphere was deficient in CO2, and that crop productivity could be greatly enhanced by introducing CO2 emissions from from smokestacks, and that earth was covered with luxuriant forests when CO2 levels were much higher.

Fertilizing the air with carbon dioxide to promote plant growth

ONE of the principal constituents making up the body of a plant is carbon, representing about one-half of its organic substance. The opinion that this carbon is derived from the soil has long been abandoned, modern investigation having shown atmospheric carbonic acid to be absorbed by means of the chlorophyll or green matter of the leaves and decomposed into its elements, the carbon, in conjunction with the root sap and atmospheric moisture, being worked into organic compounds.

Whereas atmospheric air at present is relatively poor in carbonic acid, of which it contains only about .03 per cent, at an early period in the development of our planet, when this was covered with the luxuriant forests our coal deposits are derived from, it comprised incomparably greater quantities of this gas. This fact suggested the idea of heightening the fertility of the soil by increasing its carbonic acid content and thus producing conditions resembling those of antediluvian ages.
