And according to science Fribourg offers more growing degree days

According to Gemini, lots of untrue things are true.

More useful to look at https://upload.wikimedia.org/wikipedia/commons/a/a7/World_Ha... and see if that makes more sense, although seemingly it's changing a bit and that graphic is quite old by now (2012). A plant's survival depends on more than just its hardiness and what zone it's in of course, but it's a useful starting point.

I don't think so. There are a ton of varieties of banana that are grown from seed. Humans have cultivated them and selectively bred them from seed for thousands of years, just like every other plant. The seedless bananas that dominate western grocery stores are 1 variety, Cavendish, that have been endlessly cloned from cuttings. They weren't the first seedless variety commercially available, they were preceded by Gros Michel. But either way, travel to southeast Asia and you'll find a lot more varieties on sale.

Also, do you think that it may have something to do with being cities with stone and steel that absorbs and radiates heat, and that cities are no longer as filled with trees due to urbanization and immigration filling them with people?

For context, London, Rome, and Paris have respectively gone from 2.6M, 175K, 1.05M populations to 14.5M, 4.3M, and 12.4M; so basically a 6–25x population size in ~125 years. You don’t think that may have something to do with it?

More context 10 million people produce about 1-1.5 gigawatts of continuous heat energy alone. That’s energy that would also be absorbed into stone structures of European cities even if to an unapparent degree, especially in the summers.

Unlikely

> I saw a banana tree with green bananas in Switzerland

1) I believe you. This is not rare. Culturing a banana tree is super easy.

You can easily find one ornamental dwarf banana for your office in Zurich, put it outside in summer and enjoy the sight of the little green bananas. You just need lots of water, a decent sized pot (bananas can produce fruit in pots), some manure and a summer hot. All of this can be found in Switzerland.

Just don't expect fruit.

2) Growing bananas to their harvest time is the impossible part.

Flowers need to mature all winter long, and if they touch just a little chill, commercial banana fruits will stop growing, the stems will wither and collapse to the ground. They need more than 12 months of non-stop warm temperatures to became yellow and tasty. Your banana tree should be treated as an annual herb or kept indoors for many months each year.

But, there are more in this history.

There are around 50 species of banana trees. And lots of hybrids. There are yellow bananas, green bananas, lipstick pink bananas and steel blue bananas.

Some species evolved in mountains of tropical areas. Basically a temperate climate. The trunks that support the fruits can stand much more cold without dying. The problem is that they have small short bluish green bananas that don't worth the effort.

So far, those species are collector oddities or kept for hybridization purposes; but everybody in the field would salivate about breeding a seedless banana of decent quality that stands cold. This creatures are very productive.

There is a registered case of a Phoneutria bite in UK at least, and the chef was sent directly to an hospital. To be fair, they dislike the cold so the spider had its reasons to be upset when he opened the fridge to grab a banana.

The spider is easily identified because it has four identical small frontal eyes arranged as a perfect square. Is big, bold and it warns before to attack [1] (most tarantulas are shy). And it jumps, of course. Can hide, once in a blue moon, in exported South American banana bunches (European breed bananas are spider free).

[1] If it raise the legs showing the yellow and black rings beneath is a clear warning saying "get lost right now, of I will land on your face"

Also, most of these crops were specifically domesticated in the Andes. If you go to the Andes today you can still find traditional potato farmers who take care of hundreds of varieties of potatoes of all different shapes and colors. Some are ornamental, some are edible raw, some are only used in soup, some are even used medicinally

Maybe surprising is that there are no native species of banana to "the New World" despite there being about 100 species and thousands of named cultivars.

Apple cultivars are not genetic. If you plant seeds, you're going to get some random apples, which probably aren't very good. The cultivars are all produced via cuttings.

They're more like pets in this sense. Really fun plants to have inside though.

A chef should know better than to keep bananas in a fridge!

Naval is for ships.

I live in Hungary and they seem to be relatively widespread, if not as much as in southern Europe.

They put their four front legs together, two by two, and sort of point at you.

I was told that they are aggressive because they are well fed because they feed on the sap from the bananas whereas most spiders are usually hungry.

Alternatively, you could graft the branch of a pawpaw that flowers earlier to try and get the male and female flowers maturing at the same time. You might also be able to just buy some pollen. It's actually quite easy to collect. You can use a brush to sprinkle it on a female flower

It turned out that these were fava beans, which stem from the Old World.

BTW, the four frontal eyes in a box is not considered a good taxonomic character for IDing them, as spiders in other related genera also have this. They do have a warning posture, but not a "dance" that I am aware of. Also, they are terrestrial and hunt on the forest floor. The stories of them "jumping" are largely exaggerated.

There are two sources of corruption.

The first is the urban heat island effect. Many weather stations are corrupted because although they were once in fields or other natural sites, over time cities expanded to meet the needs of the growing population and ended up building around the stations. This distorts readings by pushing up the min on the min/max thermometers, as tarmac absorbs heat during the day and re-radiates it at night. If you compute the average temperature for a day by just taking the midpoint between the min and max this makes it appear that the site is warming even if the max doesn't change i.e. there is no actual climate warming.

The second is that a large number of weather stations sit next to runways. It's intentional: pilots need to know runway temperature for takeoff calculations. But climatologists obviously shouldn't use them because not only are they next to tarmac, they're also being blasted with jet exhaust. So as population increases due to immigration (as western countries have below replacement fertility), jet travel goes up and this causes more traffic which warms the air at these weather stations.

In some countries this is a serious problem. For example, the UK is very built up with unusually high population density. The World Meteorological Organization has a classification system for weather stations in which class 1 is the best (lowest uncertainty) and class 4/5 are the worst (uncertainty of 2/5 degrees respectively, which is higher than the 1.5 degrees of warming claimed to have happened since 1850). Unfortunately nearly 90% of all British weather stations are class 4 or class 5, but the Met Office still use them to make claims about record breaking temperatures.

Climatologists have techniques they say correct for these problems, but the algorithms don't actually work. US GHCN uses something called homogenization, a kind of interpolation which spreads warmth from cities and runways into colder rural areas, creating an appearance of global warming across the entire dataset that's not there in the thermometer readings from uncorrupted sites.

Pacific island cultures are a bit unique in their relationship to the New World though. Chickens which come from SE Asian jungles have been in South America since at least 1300 AD. And sweet potatoes were grown in Polynesia around 1000 AD.

How does this work in practice? Do other trees from the same species produce male flowers first, and then female? Logically, if all trees produce female flowers in spring and male flowers in the summer then the species can only survive if the seeds can remain viable unfertilized for months (which is probably not that exceptional for plants, I wouldn't know). But if the female seeds are still viable by the time the plant sprouts its male flowers, exactly how does this prevent self-pollination?

Is a good taxonomic character if you are in Europe, as no European spider, big or small, has this eyes.

Also this is a fast way to discard other tropical spiders that could also appear on orders of imported fresh fruit and have a fearsome look but are harmless.

Tarantulas have small eyes arranged like a bowtie. Huntsmans have four eyes in a line. If you are bitten by a spider that is hairy, bigger than 10cm, and does have eyes arranged like those, is just a pinch, painful but safer than a mosquito bite. Just wash it with soap. Same if the eyes are arranged in a square but two are much bigger than the other two. Safe.

Otherwise.

If you are bitten by a cream hairy spider that has only "3 eyes", one central and two laterals (really 6 in 3 pairs) is a Sicariidae, go to a doctor.

If it has four eyes of the same size arranged in a square be cautious. If it has a middle groove in the rear part of the torax is a Ctenidae, so may be dangerous. As Phoneutria is the most common Ctenidae found in banana bunches, and as we can't discard still that every other genus on the family aren't poisonous, play safe and go to an hospital. If is a harmless related species only they can identify it, and if not you are in the correct place. They can evaluate if is a dry bite and can stabilize you and provide treatment if is not.

The other spiders that are really concerning, the Australian Atrax and Mouse spiders and the black widows are much smaller, 1-5cm, not really hairy and glossy black with red or white marks. They are mostly terrestrial.

If you have not crushed yet the spider, you may need to take a good photo from some distance. Is easier if you trap it before on a glass jar, as long as you can do it safely. If in doubt assure to bring the dead spider with you, so the doctor can see it under a microscope.

How does this explain the increasing excess deaths?

I should've just said "later" instead of "later in the year"

I'm not sure how long pollen stays viable in the environment. Some species can stay viable for many weeks but most are just a few days I think. They can stay viable for years if refrigerated properly however.

This is exactly the kind of urban heat island problem that is so important to avoid.

As to the runway point you're being sarcastic about - yes, that can happen. The UK set a record temperature in July 2022, which the BBC reports was set at Coningsby in Lincolnshire:

https://www.bbc.com/weather/articles/crm04vm30x9o

In fact it was set at RAF Coningsby at the exact moment two Typhoon fighter jets landed, and lasted only for a minute or two i.e. it was recording jet exhaust from the landing.

This fact had to be dug up through FOIA requests, it wasn't advertised by the Met Office or British media anywhere. Brits were led to believe this had occurred in some open field near a village somewhere.

Every time you read about a record breaking temperature in Britain, you aren't being told about the atrocious state of the weather station network there. Almost all the records are being set at weather stations that can't measure change in the climate due to urban corruption or being sited at runways.

Background: Class 1–2 are regarded as excellent or very good exposures, Class 3 permits uncertainties up to about 1 °C, Class 4 permits uncertainties up to about 2 °C, and Class 5 permits uncertainties up to about 5 °C because of nearby artificial heat sources or other exposure problems.

According to analyses of the released data, approximately:

22% of stations were Classes 1–3, about 49% were Class 4, about 29% were Class 5.

I guess there must be very good reasons for not ensuring that the majority of stations are Class 1-3.

So unless you want to put that down to the new houses put up, it means that temperatures have gone up.

Also the lack of rain was measurement error too.

Has nothing to do with its suitability for use in longitudinal study, because whilst a site next to a massive concrete windbreak might be a degree or two hotter than other locations in a region, unless the concrete windbreak is a recent phenomenon, it can't be the cause of temperatures at that site being higher in the 2020s than they were in the 2000s or 1970s...

I'm not saying he's right but we had here one of the highest temperatures recorded in France these days (not the highest, but we did reach a bit more than 42°C) and there's a runway just a kilometre away or so. QED.

It's used approximately twice a week by Cessnas, but probably on this day the plane had directed its exhaust on the weather station and also straight on our garden.

Not sure if the pilot was French, but there's a good chance it was an English immigrant.

Nobody honestly believes that the reason the UK is recording hotter temperatures all over the country is because immigration is driving Typhoons to land differently at RAF Coningsby

It was also insinuated that the temperature range here on this day[1] in 2022 wouldn't be abnormal in a country which had previously never experienced more than 38.7 degrees if it wasn't for the jets landing at 3:10 ish which a climate sceptic blog was excited enough to file a FOIA request to find. I don't think the person "neglecting to think rationally" is the one highlighting the absurdity of suggesting the real reason an air base recorded its highest ever temperature was routine landings of aircraft based there...

I think what's happened is you're so determined to defend arguments which are indefensible - whether it's because you don't like the sarcasm or because you actually sympathise with the idea that global warming is just data corruption - you've resorted even to suggesting that even citing counterexamples like Lingwood is an illegitimate approach to debating pseudoscience...

As we all know, meteorologists know nothing about heat islands, which actually work by saving up all the heat from urban areas built last century and discharging it in comparatively rural areas in the 2020s.

> and not the more standard explanation for minute-to-minute temperature rises of the sun coming out

It was a cloudless day.

If you had an actual answer for what made the temperature higher on that day at that site (and 46 other sites) than it had ever been there or anywhere else (including all the other airports and heat islands) even before aircraft allegedly landed, and what Typhoon operations have to do with immigration anyway, you wouldn't be stuck repeating the unsupported claims of a political blog about the absence of cloud (the Met Office recorded cloud coverage of 1 oktas at 3pm at that site that day, but I guess Chris Morrison who wasn't there and doesn't exactly hide his partisanship is wayyy more reliable than the weather station's lidar)

It may spoil an entertaining deliberate confusion, but you know the airports with the jets, and the cities full of immigrants, were clearly stated as separate from the start: "two sources of corruption ... the first ... the second".

Immigrants were explicitly linked to supposed airport-induced measurement error "as population goes up due to immigration...jet travel goes up and this causes more traffic which warms the air at these weather stations" in the original post and doubled down on by these immigrants supposedly being "a primary driver of data difficulties in climatology". I found it amusing that the example posed was a RAF base...

"be reasonable, meet them halfway."
