British Columbia – Environment Canada – 5 year averages plotted using all monthly anomalies

Published on by sunshinehours11 Comment

British Columbia, Canada (BC)  is north of Washington/Idaho/Montana. Here is the same graph for BC as I did for Washington State in my previous post.

I downloaded monthly data from the Environment Canada (EC) websites. EC treats some stations as special and calculates anomalies against what they call Normals. As of today the Normals are calculated for 1971-2000 and I am using those special stations.

This data is in anomalies in Celsius, not Fahrenheit.

The last 5 years were exactly at the 1971-2000 average. Which puts the last 5 years colder than ~1925-1930, and colder than ~1940 and the same temperature as ~1945 and ~1960.

It is also .8C colder than the previous 5 years.

The thing that struck me about this graph is that previous 5 years were not hotter than many, many other periods. By not hotter I mean the positive anomalies were not larger. What made the previous 5 years “warmer” was the absence of really large negative anomalies. The recent 5 year period saw many anomalies around -2.5C .

And notice the y axis. There are only two positive anomalies greater than 5C in the whole record and they occurred in the 1800s. But up until 1985 there were many anomalies lower than -5C and even two greater than -10C.

I wonder if those large negative anomalies were the Little Ice Age holding onto the 20th century and the LIA finally let go … or may it is all those heated buildings clustered around weather stations making sure they don’t get too cold in the winter.

 

USA/NOAA 5 year averages plotted using all monthly anomalies

Update: I posted the follow up using data from BC here.

I took the NOAA state data and calculated the 1971-2000 average for each month and then calculated the anomalies. I then graphed every monthly anomaly and calculated the 5 year average backwards using the most recent anomaly as the start point.

Washington State is not uncommon.  The last 5 years were -.3F colder than the 1971-2000 average. Which puts the last 5 years colder than ~1898-1908, and colder than ~1940.

It is also 1.1F colder than the previous 5 years.

The thing that struck me about this graph is that previous 5 years were not hotter than many, many other periods. By not hotter I mean the positive anomalies were not larger. What made the previous 5 years “warmer” was the absence of really large negative anomalies. The recent 5 year period saw the first -5F anomaly since 1995.

May is cooling in parts of Canada and the USA. Looking at the NOAA monthly data for May, this is the recent trend (over 10 years or more).

Any ideas why?

Highlighted are more than -1F/decade cooling.

HADCET June July and August trend for 350 years is a measly .009C per decade

Published on by sunshinehours1Leave a comment

HADCET is the Central England Temperature record maintained by the UK Met. The seasonal mean data is available here.

If you graph JJA (June, July and August) the trend is a measly .009C per decade.

The two warmest years are 1976 and 1826. 2011 JJA was 14.8C, below the mean, and 3C colder than 1976.

We were told we were going to fry as “Global Warming” gets going.

HADCRUT3 Northern Hemisphere – December and January

Published on by sunshinehours1Leave a comment

Update:  January data is just as unscary as December. I’ve added it at the bottom.

Has anyone ever noticed that the 3rd warmest December in the Northern Hemisphere (according to HADCRUT3) was 1939?

Anyone who wants to remake our fossil fuel economy based on this graph is insane. On top of 2006 being only .095C warmer than 1939, it was only .3C warmer than 3 years in the 1940s/50s. And its just as cold as those 40s/50s years now.


Only two years warmer than January 1863. Doesn’t look too scary. And January’s subsequent to 2007 were much colder than 1863.

NOAA 17 of 48 states warmest decade was far in the past

Published on by sunshinehours1Leave a comment

Using the NOAA data I thought I would look and see when the warmest 10 years were for each state.

17 states warmest 10 years were well in the past. Only 2 were 2002 to 2011. All of the rest but one overlapped 1998. And California was an outlier with 1988 to 1997 as the warmest 10 years. At the bottom of this post is the list with some highlighting.

Here is an animated gif of the 48 states with the warmest 10 years highlighted in gray. Click on it for the full effect.
