Whistler Tries to Extort Money From Oil and Gas Companies – It Does Not Go Well

Published on by sunshinehours1Leave a comment

Whistler ski resort makes a mess of climate extortion.

The oil and gas portion of an investors conference in Whistler has been scrapped after the resort town’s mayor demanded fossil fuel companies pay for costs associated with climate change.

Mayor Jack Crompton posted a video apology to Facebook on Thursday after Postmedia reported on his letter to Calgary-based Canadian Natural Resources Ltd.

“I sincerely regret that anyone felt unwelcome here,” he said. “We recognize there are hundreds of thousands of Canadians who work directly and indirectly in the oil and gas sector and they are very proud of the work they do.”

In the letter, Crompton asked CNRL pay a “fair share” of the town’s “costs of climate change,” including part of a $1.4-million wildfire protection budget.

But the apology hasn’t stopped investors from cancelling their trips to Whistler for the 21st annual CIBC Whistler Institutional Investor Conference in January, and Postmedia has learned CIBC has cancelled the oil and gas sector’s part of the conference.

“The Canadian energy industry has been a global leader of responsible energy development,” CIBC said in a statement. “We are committed to our clients in the energy sector as they play a key role in driving the Canadian economy.”

Crompton acknowledged in his apology how the resort community depends on fossil fuels and said Whistler has “a responsibility to respond to the climate change challenge ourselves, and do it locally.”

Climate Change Is Destabilizing Volcanoes or Climate Change Could Wake Up Canada’s Dormant Volcanoes

Published on by sunshinehours1Leave a comment

Interesting video about volcanoes and glaciers “starring” scientists from my alma mater.

I know the video is from the left-wing climate doom peddling CBC and it is quite shameful they use headlines implying climate change could “wake up” volcanoes.

I’ll concede that volcanoes can effect glaciers. But everything else is doom mongering.

A much better version of the story (from 3 months ago) is here.

“Researchers knew that fumaroles likely existed on the mountain — there had been reports of a sulphur-like smell near the mountain for years, not to mention hot springs in the area—but now, with the glaciers retreating, it seems they had emerged from beneath the snow and ice.”

 

Heating with Natural Gas vs. Electricity in BC (Canada)

Published on by sunshinehours16 Comments

Update/Correction: The author of the blog post noted in one list:

BASIC CHARGE ($0.4065/day) = 148.37

And didn’t carry it the list with the total.

And the delivery charge is 4.296 per GJ = 429.60 (100GJ for the year)

  1. DELIVERY CHARGE = $429.60
  2. BASIC CHARGE ($0.4065/day) = 148.37
  3. STORAGE AND TRANSPORT = $75.80
  4. COST OF THE GAS = $154.90
  5. MUNICIPAL OPERATING FEE = $20.40
  6. CARBON TAX = $173.82
  7. CLEAN ENERGY LEVY = $2.64
  8. GST = $42.73

GAS total corrected to: 1048.26

Not quite as dramatic a difference … but still huge.

Great blog article comparing Heating with Natural Gas vs. Electricity in BC

The conclusion: Gas Wins at 1/4 of the price.

You pay more in GST for electricity than the actual cost of the gas.

 

A typical home in the southern interior will use 100 GJ (or 27,778kWh)  of energy to heat for a year. Smaller homes and more efficient furnaces can improve on this number, as can global warming because of warmer winters. Bigger homes or poorly insulated homes will use more.

Assuming that you require 100 GJ of heat for your home for the year, your gas costs will be:

  1. DELIVERY CHARGE = $42.96
  2. STORAGE AND TRANSPORT = $75.80
  3. COST OF THE GAS = $154.90
  4. MUNICIPAL OPERATING FEE = $20.40
  5. CARBON TAX = $173.82
  6. CLEAN ENERGY LEVY = $2.64
  7. GST = $42.73

TOTAL = $899.89

Using traditional baseboard heaters, the same amount of energy would cost you over $4,000/year with BC Hydro.

  1. 27,778 kWh at $0.13260/kWh = $3,683.34
  2. RATE RIDER = $184.17
  3. GST = 193.38

TOTAL = $4,060.88

 

B.C. NDP Accidentally Admits Carbon Tax Hurts The Economy

Published on by sunshinehours12 Comments

From Spencer Fernando’s Blog

The B.C. NDP are joining a court case pitting the Trudeau government against Ontario & Saskatchewan, who are arguing the Trudeau government can’t impose the carbon tax against the will of the provinces.

But B.C. is joining on the side of the Trudeau government, saying the carbon tax needs to be imposed. And they give a very ‘interesting’ reason why.

Here’s what B.C. Environment Minister George Heyman said:

“Greenhouse gases do not respect provincial boundaries or international boundaries for that matter. We will argue that there will be harm to our competitiveness if other provinces do not put a price on carbon.”

Wait a minute…

If the carbon tax doesn’t hurt the economy, how could B.C. having one and other provinces not having one hurt the B.C. economy?

It’s almost as if applying a massive tax on everything isn’t good for the economy…

BC Tmax Grid

Environment Canada Monthly Summary Grid by Decade

2010s are the hottest decade 25% of the time, but I would argue overrepresentation due to many stations only going back to the 1970s.

The 1950s are the least hot decade. By far.

I Pledge To NEVER Vote For A Party That Supports A Carbon Tax.

The next provincial general election in British Columbia is scheduled for May 9, 2017

Yes the NDP will probably screw the poor and retired and middle class more than the Liberals.

But I won’t vote Liberal as long as the carbon tax exists.

If there is no party that is against the carbon tax, I won’t vote.

Sixteen Natural Droughts Since 1658 Worse Than Todays

Published on by sunshinehours12 Comments

Tree rings are magical. Not only can you reconstruct temperatures from the past, but you can reconstruct droughts (rainfall).

Whenever I see the word “novel approach” I worry we are in for BS.

However, since the authors of this paper are saying things were worse in the past than present I like to pretend I believe them.

They also sort of say that more dendrohydrologists are needed. Surprise.

Recent streamflow droughts in south coastal British Columbia have had major socioeconomic and ecological impacts. Increasing drought severity under projected climate change poses serious water management challenges, particularly in the small coastal watersheds that serve as primary water sources for most communities in the region. A 332-year dendrohydrological record of regionalized mean summer streamflow for four watersheds is analyzed to place recent drought magnitudes in a long-term perspective.

We present a novel approach for optimizing tree-ring based reconstructions in small watersheds in temperate environments, combining winter snow depth and summer drought sensitive proxies as model predictors. The reconstruction model, estimated by regression of observed flows on Tsuga mertensiana ring-width variables and a tree-ring derived paleorecord of the Palmer Drought Severity Index, explains 64% of the regionalized streamflow variance.

The model is particularly accurate at estimating lowest flow events, and provides the strongest annually resolved paleohydrological record in British Columbia. The extended record suggests that since 1658 sixteen natural droughts have occurred that were more extreme than any within the instrumental period. Flow-duration curves show more severe worst-case scenario droughts and a higher probability of those droughts in the long-term reconstruction than in the hydrometric data.

Such curves also highlight the value of dendrohydrology for probabilistic drought assessment. Our results suggest current water management strategies based on worst-case scenarios from historical gauge data likely underestimate the potential magnitudes of natural droughts. If the low-flow magnitudes anticipated under climate change co-occur with lowest possible natural flows, streamflow drought severities in small watersheds in south coastal British Columbia could exceed any of those experienced in the past ∼350 years.
