Weather is not climate, unless we say so

Plants in my garden suffering from four, euh, two months of "drought"...

Plants in my garden suffering from four months of “drought”…

Since about six months the Belgian newspaper Het Laatste Nieuws (The Latest News), seemed to be slowing climate alarmism. I first noticed this when reading their reporting on Haiyan. The reporting on it was surprisingly balanced. But yesterday they apparently couldn’t resist. They wrote an article about our warm winter and warm spring that we are experiencing now, interviewing their (alarmist) weatherwoman (from their paper edition, translated from Dutch):

[…] The weather has lost its bearings. According to official KMI terminology, it is ‘abnormally’ warm now for already five months. And except for February there was also much less rainfall than normal since December. […]
“It is no longer news that the earth is warming”, said Jill Peeters, our weatherwoman. “But when you see these numbers, then it is only becoming clearer. The average temperatures used by KMI, are over the past thirty years. If you were to compare with the start of the measurements, then the differences would be even more extreme”. […]

What happened to global warming? Belgium is roughly a whopping 0.006% of the earth. I have to admit that there are more countries than Belgium with this weather, but she forgot to mention for example the United States, where they had their coldest winter. If our warm winter is some kind of evidence that the earth is warming, why is the current cold winter in the United States or our “winter that never ended” just from last year, not evidence that the theory is not coping well? She has no problem with that (translated from Dutch):

The earth is warming up, but within that upward trend there will always be variability.

Here you have it. When it is a warm winter, apparently it is more evidence of global warming. When it is a cold winter, it is just natural variability… In that sense global warming can never be falsifiable and is always true. No matter what the observations are.

I agree that the temperatures rose in the last thirty years and even more in the last 160 years. But this doesn’t necessarily means that humans were the primary cause or that it is catastrophic in nature. It could as well be a recovery from the Little Ice Age. Looking at the longer term datasets cycles of about 60 years become visible. So her definition of 30 years for climate is only a measly half of one cycle, more specifically the upwards part of it. When one takes the satellite dataset (that should be the most accurate globally) temperatures didn’t rise much from the end of the 1970s on and it didn’t rise at all for a decade and a half now. Although we pumped an unprecedented amount of CO2 in the atmosphere during that period.

That would let the temperature rise dangerously.

By 2100.

Or so.

There seemingly wasn’t enough hyperbole until that point in the article. This is how she concludes (translated from Dutch):

The weatherwoman hopes that the weather makes a jump again. “And I’m talking mostly about the drought. If the coming months bring so little rain, then we really will really suffer a long heat wave. We should not hope for that. Nature is in full bloom, but therefor she needs plenty of water, and there is too little of that now.

While it had rained less than normal in most of those months it is not that it didn’t rain. She said that “except for February there was much less rain than normal since December”. This gives the (false) impression that it was much too dry in this period (except for one month). This is her own data:

Month Average (mm) Precipitation (mm)
December 2013 81 77.1
January 2014 76.1 70.1
February 2014 63.1 66.2
March 2014 70 18
April 2014 51.3 20.1

December 2013 and January 2014 were slightly below average, February 2014 was above average and only the two last months rainfall were well below average (before that, November 2013 was extremely wet, almost doubling the average for that month).

A couple months with below average rainfall is nothing special in Belgium. It happened before, it certainly will happen again. That is what averages are. Sometimes less, sometimes more. By the way, most projections for Belgium are about more precipitation in the future and we are told to worry about that. Now we should start worrying about droughts in the future too? Unless climate is changing within the time span of a couple months, the chance that this “drought” will last for long is very small. Even before her article went to press, a rain zone crossed our country and even more rain is forecasted for next week. So much for the drought.

I remember vividly the times that global warmers were saying that “weather is not climate” when they got stuck for an explanation. Now they even have to resort to the variability of weather to make their case…
