British Columbia Breaks Cold And Snow Records

by Cap Allon, June 15, 2020 in ClimateChangeDispatch

Record cold and late-spring snow helped drive-home the Grand Solar Minimum message across the BC Interior over the weekend.

According to KelownaNow Meteorologist Wesla English, the Interior –one of the three main regions of the Canadian province of British Columbia– broke a slew of cold records on Saturday.

Kelowna, Kamloops, Clearwater, Penticton, Salmon Arm, and Vernon were among the areas to set new all-time record low-max temperatures for June 13.

“A cool upper low over Southern BC produced chilly temperatures on Saturday, breaking record low daytime highs in several areas,” wrote English.

Below is a breakdown of the records (data courtesy of Environment and Climate Change Canada, and originally reported by kelownanow.com):

  • Kelowna set a new daily record min-high of 12.8C on Saturday, a reading comfortably topping the previous record of 13.3C set in 1981.
  • Kamloops saw its all-time record low smashed, from 1923’s 15C to this weekend’s 13.4C.
  • But it was Salmon Arm that actually saw the biggest change — Saturday’s low-max of 12.4Ccrushed the old record of 14.4C from 1971.
  • Clearwater’s12.8C busted the 13.3C from 1966.
  • While the 13.9C set at Penticton pipped the previous record — 1981’s 14C.

In addition to the cold, this weekend delivered rare late-spring snow to BC, adding to Ontario’s record June snowfall last weekend that brought power outages to parts of the province.

Wet snow accumulated near the summit of the Okanagan Connector between Merritt and Kelowna on Sunday,

Tree Rings & Michael Mann’s Hockey Stick

by P. Homewood, June 14, 2020 in NotalotofPeopleKnowThat

…

Somehow what starts as a perfectly sensible review morphs into Michael Mann and his discredited hockey stick!

But, as the review itself admits, tree rings tell you more about rainfall than temperature, Indeed, in a much better review in Newsweek, we read how the book reveals in detail the effect that a long period of drought had on the declining Roman Empire in the 4thC.

In fact Mann’s Hockey Stick was hopelessly flawed in many ways. (I would recommend Andrew Montford’s book, “The Hockey Stick Illusion”, for anyone interested.

For a start, the Hockey Stick was based on shonky statistics, which were guaranteed to produce a hockey stick curve regardless of the data fed into it. This was because of the way Mann used Principal Component analysis. In simple terms, Mann’s statistics blew out of all proportion any data which showed a hockey stick effect and ignored all other data.

Secondly, as far as tree rings were concerned, it was heavily dependent on bristlecone pines. It has long been known that the marked increase in bristlecone growth in the 19th and 20thC is due to CO2 fertilization, not temperature. When bristlecones are taken out of Mann’s analysis. the hockey stick disappears.

Thirdly, when tree ring and other proxy data diverged from rising temperature data in the late 20thC, Mann ignored the proxies and spliced the temperature data onto his graph.

There are also a whole host of other major flaws in the Hockey Stick, not related to tree rings.
