Canada Warming At Twice the Global Rate, Report Finds (www.cbc.ca)
An anonymous reader quotes a report from CBC.ca: Canada is, on average, experiencing warming at twice the rate of the rest of the world, with Northern Canada heating up at almost three times the global average, according to a new government report. Entitled "Canada's Changing Climate Report (CCCR)," the study was commissioned by the Environment and Climate Change Department and was slated to be released officially on Tuesday. That release date was moved up to Monday after CBC published its story about the leaked report.
The leaked copy of the report says that since 1948, Canada's annual average temperature over land has warmed 1.7 C, with higher rates seen in the North, the Prairies and northern British Columbia. In Northern Canada, the annual average temperature has increased by 2.3 C. According to the U.S. National Oceanic and Atmospheric Administration (NOAA), since 1948, global average temperatures have increased by about 0.8 C. Along with these temperature increases, the CCCR says Canada is experiencing increases in precipitation (particularly in winter), "extreme fire weather" and water supply shortages in summer, and a heightened risk of coastal flooding. The document says that while warming in Canada has been the result of both human activity and natural variations in the climate, "the human factor is dominant," especially emissions of greenhouse gases.

USA is generating all that heat, and heat rises, and Canada is above USA, so...
We generally find weak and statistically insignificant relationships between monthly, seasonally or annually averaged T max and urban fraction (Figure 3). When T max is averaged annually, the linear relationship between this and urban fraction is insignificant (at a 97.7% confidence level) at 0.25±0.42 K. The strongest relationships are observed in the winter months with December having an urbanisation effect of 0.67±0.34 K.
How much are you being paid to spread lies?
Have you been to Northern Canada? Or any part of Canada that is not with in 100 miles of the US border?
I don't think Urbanization is the problem here.

Canada will soon be a livable country.

When the permafrost thaws, the carbon in it starts getting converted to CO2 and methane. There's enough carbon in the permafrost to torch the planet.

Geoengineering options include increasing albedo through deforestation.
Not for this report. See chapter 4 for where the data was collected. It was individual stations. A grand total of 32 stations - located in towns - across both the NWT and Nunavut. That is for an area of 3.1 million km^2 - a bit more than Western Europe as a whole (Germany through Ireland, not including Scandinavia).
As far as satellite data, it shows the predictions are all pretty much wrong, and lends evidence to the sensitivity of CO2 being about half the value as used in modeling.
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
All the climate models show that temperatures should rise faster closer to the arctic, here in Norway we have measured the same rise as in Canada, i.e. about twice the global average.
Norway starts at 58N, North Cape is 71 degrees North. Except for the Gulf Stream Norway would not be habitable at all.

You claimed that satellites don't measure air temps.
No, I claimed that they don't measure surface air temperature. There's a standard definition for that, and it doesn't mean the bottom half kilometer of the atmosphere. It means the temperature a small distance above the surface.

Not sure if you're trolling or stupid, but at least this conversation can help to educate others, so I guess it doesn't really matter either way.
Some places are not warming at all. Look at the white blob in the north Atlantic. This is possibly a sign that the Atlantic Ocean’s Meridional overturning circulation (AMOC) may be weakening as a result of increased fresh water due to Greenland glacier melt. This was the premise of "day after tomorrow".
If the AMOC were disrupted, it could divert the Gulf Stream waters that usually flow northward, past the British Isles and Norway, and cause them to instead circulate toward the equator. If this were to happen, Europe's climate would be seriously impacted
"Anomalies"? Really? Not "conflicting data"?
No. Please educate yourself: https://www.ncdc.noaa.gov/moni...
Anomalies vs. Temperature
In climate change studies, temperature anomalies are more important than absolute temperature. A temperature anomaly is the difference from an average, or baseline, temperature. The baseline temperature is typically computed by averaging 30 or more years of temperature data. A positive anomaly indicates the observed temperature was warmer than the baseline, while a negative anomaly indicates the observed temperature was cooler than the baseline.
It makes them a lot milder though. It's been years since we had a good run of -50C.
"Towns" in the NWT and Nunavut have no pavement. The roads are gravel and ice, with ice predominating for roughly 10 months of the year. And the roads extend about 1 to 1.5 km total - from one edge of town to the other - and then there are no more roads at all. As for buildings re-radiating heat at night - again these towns are small, the buildings are small, and they never really get all that warm. I doubt Stevenson screens or anything else are picking up much heat off of them.
Yeah, the biggest risk Canadians face from global warming is probably Americans deciding we need to expand our borders as our own territory goes to hell.
A word of advice - take a good hard look at our track record of treaty violations and genocide with nations who offered to share before making any decisions.
