Scientists are suspecting that not enough winter in the Arctic has led to too much of it across the rest of Canada.
From Toronto, where ice storms cancelled baseball games, to Calgary where residents this week faced yet another heavy snowfall warning, April 2018 has come to feel like endless winter.
Some climatologists say this is the future — long stretches of freakishly unseasonable weather that flip to something else on a dime.
“It was looking like it was going to be the warmest December on record in Western Canada,” said David Phillips, Environment Canada’s chief climatologist.
“Then it turned on you — several days of -30 C. It was from one extreme to the other.”
In Ontario, Ottawa’s warmest day so far this year was on Jan. 12 when the temperature hit double digits. That hasn’t happened since.
“They had their spring in February,” Phillips said.
The East Coast endured five massive nor’easter storms in three weeks.
Why? Icy Arctic air is normally held back by a strong, high-altitude, west-to-east river of air called the jet stream.
The jet stream is powered by the temperature difference between the Arctic and mid-latitudes. But the Arctic is warming faster than anywhere on Earth, especially this year, when temperatures at the North Pole were up to 30 degrees above normal.
That weakens the jet stream. And that, said Rutgers University climatologist Jennifer Francis, is the problem.
“When the jet weakens, it tends to take these bigger north and south swings,” she said.
“When it takes one of these big southern swings, it allows all that Arctic cold air to plunge much farther south than it normally would and it tends to stick around there longer.”
Hence, ice storms in April.
It’s not quite that simple. There are multi-year temperature cycles in the Atlantic and Pacific oceans that have their own impact. The Gulf Stream, which used to reliably move warm water around the Atlantic, is weakening. And this was a La Nina year, when lower sea and air temperatures in the Pacific brought more cold and snow to much of North America.
Many scientists aren’t completely comfortable directly linking melting sea ice and weather.
“There is likely some connection, especially early in the winter,” said Faron Anslow, a climatologist at the University of Victoria.
“It’s being studied, and single events or even sequences of events can’t be tied to that cause yet.”
Phillips, who called this winter unique in his 50 years of experience, believes there’s something to the link.
“There’s so many different factors at play. But I think it comes down to that very simple reason why the jet stream is wobbly rather than straight — the gradient of temperatures between the north and south is less.
“That is the major climate control to the position of the jet stream. And when it weakens, it wobbles.”
Evidence for a sea-ice link is building and at least 15 recent papers have found a connection, Francis said.
“I don’t think you’d find a scientist who’d say there’s nothing going on. The events that we’ve seen in the last few years are very consistent with what we’d expect.”
Arctic sea ice isn’t recovering. So if the effect on southern weather is real, look for more of the same, said Phillips.
“It’s the preview of what we’re going to see. The circulation has changed. It’s almost a fundamental change in our weather.”

Yes, global warming.

Geezus. Just stop.

We had a year with no summer in the early 1800s, and everyone with any brains at all knows the same solar cycles are in play today as predicted by actual scientists. So all this QWACKTARD GRANT SUCKING NON SCIENCE is just a lying scam because BUDGETS DO NOT BALANCE THEMSELVES and because TECHNOLOGICAL NATIONS MUST BE DESTROYED.

How many times do you need to be reminded to take your medication?

...so it isn't climate change any more, it's now global warming makes it colder again.


Speaking of being on drugs.

Tim Ball (PhD) sank Michael Mann in court: so have a nice day at the propaganda mill.

Global warming first.

Climate change second.

Ice usually melts in the spring, snow falling this late in the year, that far south, not so much.

duh

No, that's just where I chose to insert the continuous stream of changing lies into that post.
(Are you using a reading program? If so, please set it to english.)

Tim Ball PhD was canada's senior climate PhD, who won in court, so of course the commienaziglobalist global warming tax SCREW freaks would ignore him and that verdict.

Say, is that the same MAY that just lied about Putin poisoning the skrypals and assad poisoning his own people? While it turns out to have been THE commienaziglobalists all along?

No, that's literally how it works.

Climate Change has been in the scientific lexicon since the 19th century. It was understood as a response mechanism.

Global warming is a catalyst for that response.


Now you know!

Let's look out the window at the real world shall we?


90 per cent snow cover - unusual, or spring in Canada?
https://www.theweathernetwork.com/ne...nowpack/99594/

The other 10 % has ice on it.

Snake oil was in the scientific lexicon back then too...

for the same reasons.

I’ll be clearing the Arctic ice from my driveway today.

If you put salt on it and it melts, that will just make more snow, which you will then have to shovel again.

according to the slyentists MF's employers just bought anyway.

You have to take pity on Mentalfloss.....He hasn't been quite the same since his head on (literally) collision with a train some years ago.
Good thing the train was stopped!

I had a neighbour who said he had a puppy that used to chase parked cars...once.
They still miss the cute little guy.

Poor bugger bumped his head at full gallop, so hard, so many times, it impacted his spine, stunted his growth, and then after surviving all that, for some strange reason, he just shorted out.

Impossible... The North has been ice free since 2013
