Antarctic sea ice grows 2 million square kilometers in 4 years…
It’s hard to back up the statement: Global warming is global. Some places have seen warming over the past 40 years (e.g. Arctic), but other places have not.
Antarctica definitely has not been playing along with the man-made global warming hoax. (Yes, man has caused some of the warming, but not all – and it certainly isn’t catastrophic).
Antarctic sea ice surges
Though Antarctic sea ice fell to a “record minimum” in 2017 – after having reached a “record high” in 2015 – the latest data from the National Snow and Ice Data Center show sea ice at the South Pole has bounced back robustly since, surging some 500,000 sq km above the mean.

On March 26, 2017, Antarctic sea ice measured 3.055 million sq km. Four years later, sea ice reached 5.103 million sq km. That’s a difference of more than 2 million sq. km., which is an area the size of Saudi Arabia!
No way to ignore natural factors
So why would sea ice grow so quickly? If the ice had disappeared, many would blame it on greenhouse gases – absurd of course. And it would be just as absurd to blame the recent gain on global cooling. Obviously there is a complex array of natural factors at work – factors that climate alarmists consistently have ignored over the past decades.

Hamburg spring trending a bit later
One interesting climate anecdote is spring trend in Hamburg, Germany. It appears that Hamburg’s forsythia flowering is occurring increasingly late, according to our friends at Die kalte Sonne here. Also not what we’d expect from “warming”.
The perceived beginning of spring in Germany is when the Hamburg forsythia bush in the city centre blooms. The location at the Lombardsbrücke on the Alster is well suited because the surrounding area has hardly changed in the last 50 years. Phenologist Jens Iska-Holtz dates the flowering date for 2021 on the 25th of March, which is 84 days since the beginning of the year. Over the last 50 years, the following graph emerges:
Fig. 1: Development of forsythia flowering in Hamburg since 1972. The X-axis shows the years since 1972, the Y-axis the flowering date, measured in days after the beginning of the year, i.e. from 1 January.
There has been no significant trend in the flowering dates of the Hamburg forsythia bush on the Alster. The average is 79 days from the beginning of the year. At 84 days, the start of flowering this year was slightly above the average.
Hamburg spring 11 days later since 1990
Next we take the new climate reference period 1991 to 2020 as the period under consideration:
Fig. 2: Development of forsythia flowering in Hamburg since 1991. Note: rising trend line means delay. At the beginning of the observation 31 years ago, the forsythia tended to flower at the end of February, the flowering date moved further and further back into March. The last February flowering was in 2008.
Cooling February
What explains the delay in spring since 1991 in Germany? Global warming? Carbon dioxide?
The month of February is decisive for the forsythia blossom. The corresponding graph from the Hamburg weather station for the month of February shows only a slight cooling since 1988.

Let’s move on to the question of the year since which the forsythia blossom has been delayed:
.
Fig. 4: Since 1985, i.e. for 37 years, the forsythia, the DWD’s flagship shrub for the beginning of spring in Hamburg city center, has shown a slight delay in flowering of 5 – 6 days.
The reason for the rising trend line and thus the delay is probably the warm February months of 1988/89/90 at the beginning of the observation period.
Result: Forsythia flowering has been slightly delayed for approx. 37 years – quite clearly from 36 years onwards – although the shrub is located in Hamburg’s inner city, in a heat island. You will probably look in vain in the media for reports on the delay trend of the Hamburg spring bloomer.
Those who read the Die kalte Sonne [or NoTricksZone] blog will therefore know more.
Bonjour,
1988 c’est un peu court pour affirmer que les mois de févier se refroidissent a Hambourg.
Refaites nous le même exercice mais cette fois depuis 1900.
Désolé mais j’utilise la vraie langue de la diplomatie Européenne, vous pourrez me traduire sans problème.
Cordialement.
Phil
Translation of Philippe’s comments:
“Hello,
1988 is a bit short to say that February is getting colder in Hamburg.
Do the same exercise again, but this time since 1900.
Sorry, that I use the real language of European diplomacy, you can translate me without any problem.
With kind regards.”

@Philippe:
Yes, of course it has warmed since 1900….and even since 1700. But it has cooled since 1000 AD, or 7000 BC. Climate is defined as the 30-year average, and so it’s okay to use 1988 as a start point for looking at the recent climate trend. Recall alarmists always tell us it’s getting warmer, but in fact it isn’t and hasn’t been at many places. Spring in Hamburg illustrates this. What’s interesting about the blossoms as that it not only tells us about surrounding air, but also the soil conditions. Soil is also a part of our climate. Spring arrives when the soil is ready.
Concerning French as being the real language of diplomacy, I’d have to argue that you’re stuck a bit in the past. The English language has thrown French of that throne quite some time ago. Today international science, most of diplomacy, commerce etc. are done in English. Even German, Russian, or Spanish are in broader use. Times have changed. -PG
2 mill sq. km is also as big as Greenland!

It’s not surprising that Antarctic sea ice is increasing.
The Southern Ocean all around Antarctica has had a cool anomaly continually for decades now.
It’s kind of like a gorilla in the room – it’s always there but almost no-one talks about it.

True, the warming of earth does not seem symmetric. I would expect to see more ice in the antarctic. What happens in Hamburg seems to be an exception to the rule.

The heat is coming from the north and is going south…. slowly…
