Antarctic Sea Ice Grows 2 Million Sq. Km – Area As Big As Saudi Arabia. And: Hamburg Spring Arriving Later…

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.

Cropped chart parts,  source: NSIDC.

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.

Here’s the March 26, 2021 satellite photo of Antarctica:

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”.

By Josef Kowatsch

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.


Fig. 3: February temperatures in Hamburg since 1988 according to original data from the German Weather Service.

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.

If there was any ‘Global Warming’ to be observed in reality, it would indeed be “Global”. The search continues.

Antarctic sea ice is always up and down.. not much happening there

But the fact that NATURE shows a later start to Spring, in an urban area, will require some imaginative and fantasy-based explanations from the AGW cultists. 🙂

Antarctic Sea Ice Grows 2 Million Sq. Km – Area As Big As Saudi Arabia. And: Hamburg Spring Arriving Later

This got me to wondering what our bastions of truth were saying. The BBC is remaining tight-lipped, the only recent (March) article Auntie has gives a rather different angle:

Antarctic seafloor exposed after 50 years of ice cover

The Grauniad is similarly silent, the most recent news came in January:

Global ice loss accelerating at record rate, study finds

…the melting of the Greenland and Antarctic ice sheets [is] speeding up the fastest, research has found.

The rate of loss is now in line with the worst-case scenarios of the Intergovernmental Panel on Climate Change

It’s hard to back up the statement: Global warming is global. But full marks to the Guardian for a valiant and rather unhinged effort.

In the please donate money blurb at the foot of the page is this little gem…

millions rely on the Guardian for independent journalism that stands for truth and integrity.

The Guardian’s truth, that is.

You’ve been schooled on this before. Red is a study that found warm conditions, blue found cool conditions. The other colors are for wet or dry. Notice how studies that found warm conditions OVERWHELMINGLY outnumber the studies that found cool conditions and it’s across the entire globe.

You have a choice, either believe in the known liar, Michael Mann, or believe the hundreds of other researchers that represent many different disciplines who collectively found that the MWP was global. What’s it going to be, LoyD’oh?

It doesn’t matter if the MWP was global or not. What matters is whether the models can simulate persistant regional change or not in their control runs. And they can’t. Or at least there is no evidence I’ve seen to suggest that any model ever produced a habitable Greenland, for example.

Nice work, as usual. Only wish, Charles, that you didn’t always feel compelled to add things like, “(Yes, man has caused some of the warming, but not all – and it certainly isn’t catastrophic).”

We all here, I imagine, know that that “not all” is miniscule (if any), but anyone who comes here who doesn’t already know that would imagine that you mean “a majority” or some large part. And any actual warming is not only NOT “catastrophic,” but beneficial, as is / would also be any rise in CO2 levels.

It’s a good idea to notice the small things, too, such as a fly showing up on the front steps, just because it was a warmish day, e.g., above 45F. Then the temp drops to barely 35F overnight, the chill comes back and the fly is gone. It’s just weather, spring weather, which bounces back and forth and then settles in by mid-April.

Still, I have seen early leaves arrive and stick around in mid-March and the weather just warmed up a little more each day. It’s just weather, seasonal changes and nothing else.

If the weather stayed cold until Memorial Day, as in the 40s day-time, I’d be concerned about it, based on my location, because that is not normal. One year is a fluke. Ten years of it in a row – not a fluke. There’s no ‘on-off’ switch in climate change.

Is anyone monitoring the gas discharge volumes of active volcanoes like Etna. There’s a bunch at work now, including the newest in Iceland: Bob the Baby Volcano, on the mid-Atlantic ridge. He has a lot of fans watching him.

It’s as obvious to most of us that seasonal changes are nothing but seasons, and have little to nothing to do with climate or its changes.

Might as well go big here. Arctic Sea Ice extent yesterday was above that for the same day in 2005, 2006, 2007, and 2015 – 2020 inclusive.

Phew, I’m sure Guardian readers and BBC watchers everywhere are breathing huge sighs of relief.

March 29, 2021 6:42 am

Re Antarctic sea ice: The UAH satellite temperature data shows, that for the 42 years of monthly lower troposphere measurements, the Antarctic zone has had a slight but not statistically significant increase in temperature. Heading North through the Southern Extension, Tropics, Northern Extension and Arctic zones gives a steady rise in the rate of increase of temperature to the maximum of 0.25 deg.C per decade in the Arctic zone.

This is to be expected given that the land area predominates in the Northern Hemisphere and the ocean area predominates in the Southern Hemisphere. For the same heat input from the Sun over both hemispheres, the temperature will be higher in the Northern Hemisphere due to the difference in heat capacities of the land surface in the North and the ocean area in the South.

As there has only been a minor difference in the CO2 concentration from South to North, perhaps the temperature is merely reflecting a return to a median after the Little Ice Age. It certainly cannot be increasing due to an increasing CO2 concentration because the ‘back-radiation’ from the atmospheric CO2 absorption bands is less that 9% of the Earth’s emitted radiation (for an average surface temperature of 15.5 deg.C) and 99.8% of that is in the 15 micron band which is the peak radiation from a surface at -80 deg.C. The temperature of a surface can only be increased by receiving radiation from a hotter source, that is, greater than 100% of the Earth’s emission with a peak less than the 10.044 micron peak from a 15.5 deg.C surface so definitely cannot be any warming due to CO2.

Remember there is nothing magical about ‘back-radiation’, everything around you is radiating heat in accordance with its temperature. You do not feel any heat unless the surrounds are hotter than you.

The Antarctic Peninsula is one of the fastest cooling places in the world lately. Pepperidge Farm remembers when the AP was the poster child of global warming doomaghedon.

March 29, 2021 6:51 am

Some places have seen warming over the past 40 years (e.g. Arctic), but other places have not.

That’s widely accepted, isn’t it? Even the IPCC has stated this much (see paragraph 4 here):

However, all the global surface (and satellite) temperature data sets show that more regions have warmed than have cooled, meaning there has been an overall increase in average global temperature over the various periods of measurement.

A possible slight delay in the flowering of fosythia bushes in Hamburg is a pretty weak retort to the various temperature observations.

Depends upon when you start your time series. The trend from the Holocene Optimum is down. Ditto from the Egyptian, Minoan, Roman and Medieval Warm Periods. Likewise in the US since the 1930s. Probably globally as well, but data are missing or have been fudged.

Starting from the Little Ice Age Cool Period, or the cooling cycle of 1945-77 within the Modern Warm Period, of course will show a warming trend. But slight and not the least bit out of historical norms.

Natural fluctuations swamp whatever negligible effects at local and regional scales there may be from human activities.

The period 1945-77 is 33 years long (inclusive). There have since been 43 full years starting 1978, with statistically significant warming in all global data sets over that period. If the cool period 1945-77 is part of a cycle then that cycle is running a little late.

Also, NOAA shows a trend of +0.17C per decade warming in the US since the 1930s, with each full decade from 1981-90 onwards being warmer than 1931-40. The warmest full decade on record for the US lower 48 was the one just ended, 2011-20 (+0.96C warmer than 20th century average, compare to +0.34C for the 1930s).

Measured temperatures do not take into account known biases introduced by such things as UHI and especially Time of Observation. The second chart shows Texas only, not the entire US and, again, it uses data that has not been processed to remove known biases.

As stated, I was referring to the official NOAA annual average temperature data for the lower 48 US states. Not summer only; not Texas only; and not unadjusted only.

Possibly, although another explanation could be that Forsythia bushes have greater brain power than climate “scientists” when it comes to measuring temperatures out there in the field or even in an urban heat island.

Given my opinion of the brain power of climate “scientists”, I’m leaning towards that as the explanation.

So air has warmed a little bit, increasing evaporation (on average) and increasing cloud cover (on average), causing later blooming due to a lack of that photosynthetic fuel, sunshine. Never to worry, AMO is headed cooler, the sea surface will cool down a degree or so, slightly cooler but less cloudy air will be advected over Hamburg’s forsythia once again.

About Sea Ice

Warm tropical currents remove sea ice. Ice that is pushed into the warm tropical saltwater currents from the tropics thaws and chills the ocean currents to below freezing and sea ice forms. When there is not enough ice on the land to push ice into the ocean currents, the evaporation and snowfall with warm water close to shore rebuilds the ice on land. When the ice is sufficient more ice is pushed into the water and sea ice forms and turns the ice machine off. This is a natural dynamic cycle. Sea ice must be removed to rebuild land ice. This process is self-correcting
This works
the same in the Arctic and in the Antarctic. The cycles are not the same
magnitude and are not in phase with each other. and they do not have the same cycle
Without warm times with no sea ice, there would not be sequestered ice in Polar Regions.

Reply to  Herman Pope
March 30, 2021 7:30 am

Proof of this is recorded in Ice Core Records. Warmest times have most ice accumulation and coldest times have least ice accumulations. Warm times with less sea ice correlate with more ice accumulation. Cold times with more sea ice correlate with less ice accumulation.
