Alarm-Silencing Spring: Data Show March Mean Temperatures Have Not Been Warming Alarmingly As Claimed

By Kirye

Today we’ll take a look at March mean temperatures and their trend for some locations for which almost complete data are available from the Japan meteorology Agency.

Though March is only a single month, it is important because we often hear how spring is supposedly arriving earlier due to global warming, and as a result winters will get shorter before disappearing altogether, according to some alarmists “experts”.

The arrival of spring is also important because the length of the growing season depends on it.

No trend in Canada in 30 years

What follows first is the chart for March mean temperature for 9 stations scattered over Canada. These stations were selected because they are the very few that have almost complete data sets going back 3 decades.

Data source: JMA

As the chart for Canada shows, spring in reality is not arriving earlier and the country’s already short growing season has remained short for 30 years.

Ireland springs cooling

Next we look at Ireland, where the data were complete enough at 6 stations:

Data source: JMA

In Ireland the Northeast Atlantic island has seen its spring cooling since 1983, a total of 37 years. Moreover, the downward trend has even accelerated since the late 1990s.

Flat in France

Moving to continental western Europe in France, and looking at the JMA data from 6 stations scattered across the country, we have the following plot:

Data source: JMA

Here we see the spring month of March has not see any warming in over 30 years.

Sweden growing season shortening?

Finally we look at data for March from 5 quality data stations from the JMA database from the Scandinavian country of Sweden:

Data source: JMA.

In Sweden we see that March has cooled off over the past 30 years, which points to the potentially bad news of shortening growing seasons there.

Although this is only a random sampling of data from the northern hemisphere, they show that the alarmist claims made by global warmists are more hype than they are reality.

    Interesting….I record temps for Env. Canada, and march of this year will be 30 for me…i’ll have to check my data trend….for the 30 years though I have a ‘slight’ up tick, but that should be expected as my small town has grown from 2000 to 30000 now in that time….UHI…

      Hi there…forgot all about this!
      Anyhow, I just ran my data out of ssms, and sure enough, in Southern Alberta, Canada, my trend is slightly down from 1990 to 2019.

      if you would like to contact me…use the e-mail from this posting. I don’t use it much as it is my ‘junk’ e-mail, but I do monitor it from time to time

    Just look at how poorly the IPCC Models do. They are awful. Even an 11 year can idenitfy the problems as this video highlights.

    Thanks Kirye.

    File this under weather is not climate:

    This is a report of the weather (cold and snowy) for the first two months of 2019. The station is in northeast Oregon; Pendleton, National Weather Service. The Fahrenheit scale is used; sorry about that.
    One table includes Yakima – in central Washington State (WA).
    Biggest snow events missed WA this year. Snow and wind caused drifts that closed highways in the southeast of WA.
    Overall, as the text explains – it was cold.
