So what was the previous record and when?

nerdponx2• 3 years ago

Winter record? Or all-time record? Because right now they are breaking all-time records in mid-winter. I'm not sure if the exact numbers really matter right now.

hattmall5• 3 years ago

Not surprisingly as we increase the number of records we keep, we increase the number we break. Most of this monitoring is only going on for about 20 years.

Having grown up on the eastern face of the Rockies, where temperatures could go from -15 C (a bit colder than normal) to 15 C (well above normal) in a matter of hours, I would also like some context.

Perhaps the best approach would involve an examination of trends, rather than chasing after events with shock value. The problem is, it's hard to grab people's attention like that. Some people seem to respond better to concrete, rather than abstract, events. Then there is the media's attention arms race, which distorts our world view by placing the extreme above the mundane.

102F is hot?

I imagine its rare for that region, but compared to India/Pakistan temps, that is was underwhelming.

EDIT: OH ITS MID WINTER! Wow

cassianoleal• 3 years ago

Mid winter in the Andes and most of it pretty low south. It was supposed to be freezing cold.

Obviously the location matters. This isn’t a where’s the coldest/hottest competition.

blooalien• 3 years ago

Yeah, 102F is pretty hot, but it's insane for mid-winter. Downright terrifying to anyone who's been really watching this madness progress over past decades (as opposed to hiding their heads in the sand like so many have been until recently).

aqme28• 3 years ago

Average weather this time of year for them is highs of 59 and lows of 39, dropping down occasionally to freezing.

Tagbert• 3 years ago

Are you quoting Fahrenheit temperatures? It would help to add "F" in that case.

gmuslera• 3 years ago

A couple of weeks ago happened the same. At least in Uruguay, that typical winter temperatures are around the low 10s Celsius, we had several episodes where temps went to near 30°C. Even we went from a cold wave with near 0C to almost 30 in a couple of days.

There is a seasonal high peak near the start of the winter (that happened too), but being so hot so frequently is very atypical for this season.

Aunche• 3 years ago

Where is this happening? I've tried looking up the weather in several towns in Chile and they all look mild to me.

alistairSH• 3 years ago

It’s winter.

fermuch• 3 years ago

I'm on Brazil and yesterday we had 30ºC (about 86F). It's crazy to have these temps in winter! And that was yesterday. Today, it is about 16ºC (60F). Crazy times! No one knows if they should prepare winter or summer clothes.

tambourine_man• 3 years ago

I can only imagine the temperatures Brazil might reach in the summer from now on

rodrigodlu2• 3 years ago

Well, it's definitely weird this year.

I'm in Rio, but I'm from south Brazil, my entire family is using more meds to counter allergies due to temps and humidity changing a lot.

I'm changing from using winter clothes (long sleeves) to use air conditioner to feel less a change from 14oC to 30oC that is usually associated to autumns in south, not winters in Rio, that are usually stable around 22oC without a high amplitude that I'm feeling now.

The city my dad lives near Porto Alegre already suffered twice due to extra tropical cyclones. Something that I heard only few times in my childhood.

Uruguay facing water challenges is new - droughts in the south plains of Rio Grande do Sul (south state bordering UY) and UY is not new - but the severity is.

dghughes• 3 years ago

People don't get sick from temperature changes. I'm in Canada and in winter go from a 25C house to -25C outside. We'd all be dead of that were true. Late winter early spring I am outside in a t-shirt shovelling show in -7C.

Vox_Leone• 3 years ago

I'm in upstate Sao Paulo and we are having a mild winter. Cooler than prior years. Northern Argentina and Chile are having above normal temps alright [having El Nino next door], but the eastern [high elevation] SA [Brazil] is definitely cooler.

cerol• 3 years ago

The city my dad lives near Porto Alegre already suffered twice due to extra tropical cyclones. Something that I heard only few times in my childhood.

One thing I noticed is that local governments (and their respective climate departments) are being much more vigilant and proactive with climate events. And we are in a way paying much more attention to the frequency of climate events. Trying to correlate your own experience of "frequency of events" is a very tricky thing, since we can pretty much condition ourselves to rememeber pretty much anything we want.

Back in the day there were tropical storms and cyclones, and we just moved on. But now local governments will proactively cancel school days if there is a even a hint of a heavier storm. Which is great, but it does mess with our ability to actually estimate frequency of events.

aitchnyu2• 3 years ago

I would do anything to avoid getting sick from June to November due to constantly changing weather in this part of India. Is there some method? Already have medicines.

flobosg2• 3 years ago

38.7C at Vicuña and Chiguinto hottest winter day for Chile;for Coquimbo even an all time high for any month.
Remember:It's winter...

I would not be surprised if the Tonga Eruption has something to do with the current extremes [0]

Could be, water vapor is more potent than CO2 apparently.

paganel3• 3 years ago

It's interesting how we're already in August and places like Paris and Northern France are still at 21-22 degrees Celsius in the middle of the day [1], and I don't remember any heat-wave news that might have had involved France this summer (unlike past recent summers).

Looks like there's something happening over the North Atlantic [2], as the very hot hair present in Southern Algeria/Sahara seems to have become "trapped" in there, unlike in other summers, when it was managing to make its way up North eventually.

dekervin• 3 years ago

It's a simple google search away [0]. There was a heatwave like 2 weeks ago.

paganel3• 3 years ago

I specifically mentioned "Paris and Northern France", the post that you linked to mentions Southern France.

I remember that in recent summers we had news items like this one [1], with temperatures in Paris reaching 36 degrees Celsius on August 3, 2022, 39 degrees on August 7, 2020 [2], and 42.6 degrees on July 26, 2019 [3].

But it looks like absence of news (no heat-wave for Paris this summer just yet, unlike in 3 of the previous 4 years) is not news anymore.

vladvasiliu• 3 years ago

We've had a few weeks with temperatures abnormally high for the period during June.

And until last week or so, the South of France has had very hot temperatures, too.

---

edit: According to Wikipedia, Paris is actually quite "normal". The daily mean is 20.9/8 in July/August, with averages between 16 and 26 ºC. This is pretty much what I've noticed.

https://en.wikipedia.org/wiki/Paris#Climate

realusername3• 3 years ago

France had abnormal temperature in June with a complete full month (!) without rain at the time.

Right now it's back to normal weather.

contravariant• 3 years ago

Er, I share your concern for the environment, but I don't think we need to be concerned about it being not quite summery warm in august.

LatteLazy• 3 years ago

Somehow, despite doing nothing except make it worse for decades, this problem has gotten worse. I for one am shocked by this clearly, repeatedly predicted outcome.

TheRealHB• 3 years ago

Original post is blocked for comments (I wonder why)...

misja111• 3 years ago

Not entirely suprising, this year the El Nino effect is taking place again (https://en.wikipedia.org/wiki/El_Ni%C3%B1o) so extreme weather was to be expected.

Add to that the global warming and you could put your money on it that a lot of weather records would be broken this year.

gmerc• 3 years ago

It’s too early for El Niño. Which doesn’t bode well

flobosg2• 3 years ago

In Chile, El Niño is mostly associated to increased rainfall, though.

boredumb• 3 years ago

El Nino season is upon us

A gentle reminder to everyone - we don't have to be passive observers of the unfolding global climate catastrophe. We can pretend that we are intelligent, responsible grownups and go do something about it.

westcort3• 3 years ago

If governments wait too long some rogue organizations might start geoengineering efforts. A few orbiting Mylar shields are in order.

giraffe_lady3• 3 years ago

I know we're all really dedicated to solving social problems with far fetched technology but this is a lot even for here, come on.

voisin• 3 years ago

As a (hopefully) intelligent, responsible adult, I am at a loss as to what to do that will have any effect. I’ve installed solar, and a heat pump water heater, I don’t have AC despite the sweltering temperatures. I eat primarily plants. I vote for the party that lies to me most persuasively that they will do something about the environment, though I know neither party will do anything of substance.

And yet I turn around and feel that all my efforts are undermined by neighbours who take their giant trucks and 5th wheels or travel trailers on long summer drives at 4 miles per gallon for fun.

Until we have COVID-style restrictions on our lives, we as a society will never voluntarily give up all the bullshit that is feeding climate change.

ASalazarMX• 3 years ago

Until we have COVID-style restrictions on our lives, we as a society will never voluntarily give up all the bullshit that is feeding climate change.

Oh, we will. When food, shelter, energy, etc. become scarcer and more expensive, we will change our way of life, whether we like it or not.

avgcorrection4• 3 years ago

This is what 40 years of propaganda by the likes of British Petroleum (the ones who invented “carbon footprint”) about how climate change is about middle class people making consumer choices does to you.

xinayder5• 3 years ago

Uhh, did no one bother that the author claimed 39C for the Andes but like, the chart itself shows about 16C for the peaks? or am I reading the chart wrong?

I'm brazilian and I'm pretty sure that if this was actually true, we'd have heard this on the news and not on a random twitter profile.

EDIT: unless someone can point me to an actual reputable source, this is fake. I googled for "chilean andine record winter temperatures" and there's not a single source claiming it reached over 30C this year mid-winter.

EDIT2: and I can't find it either on weather forecast websites any absurdly high temperatures for these regions.

madaxe_again2• 3 years ago

You are indeed reading the chart incorrectly.

The chart is temperature ANOMALY - so that’s 16 to 18 degrees over the normal temperature - not absolute temperature.

Link with absolute readings.

I’m unsurprised you’re not seeing it in tv news in Brazil - your country denies the existence of climate change, and wants to chop down the Amazon for a quick buck. It would hardly fit with the popular narrative.

This is a very uninformed take that generalizes a country of 200M+ people. Believe it or not, but people in Brazil are just as worried about climate change as you

Just because from 2018-2022 we had a dumbass as a president doesn't mean the average brazilian doesn't worry about it. Traditional US-stupidity nonsense on this comment.

hi_dr_nick• 3 years ago

Not sure if real or not, but the figure is showing temperature anomaly... basically difference from average. So the numbers do line up.

wewxjfq• 3 years ago

The chart shows the temperature anomaly, i.e. how much the temperature differs from the temperatures observed in the reference period. I can't say anything about the website that generated the chart, but ECMWF is legit and when I look at the ECMWF models, I can see similar anomalies for South America right now, so the chart is correct.

The claim about the 39°C in the Andes doesn't seem right however. They are having large anomalies, but since the temperatures should be below or near zero there, a +10°C anomaly only causes sweatshirt weather and not summer heat.

tvaughan• 3 years ago

I live in the south of Chile. There has been snow only one year within the last three. There is not a person alive who remembers a season without snow. Normally there should be about three meters where we live. This is as extreme as if there was no snow in Lake Tahoe.

tomaspollak• 3 years ago

I googled for "chilean andine record winter temperatures" and there's not a single source claiming it reached over 30C this year mid-winter.

Maybe that's because chilean media outlets are written in spanish instead of english. :)

xinayder5• 3 years ago

As I googled it again today, there was this news article in a brazilian media outlet: https://g1.globo.com/meio-ambiente/noticia/2023/08/02/chile-... posted 10h ago

xinayder5• 3 years ago

There's this article from a brazilian newspaper posted 10h ago: https://g1.globo.com/meio-ambiente/noticia/2023/08/02/chile-...

I don't understand what your comment is trying to say, care to expand?

nerdponx2• 3 years ago

This thread is full of people jumping to explain away a highly anomalous weather event as being something other than evidence that points modestly in favor of an overall changing climate.

woliveirajr2• 3 years ago

It's just a fact, not an analysis: sometimes, in the past, there were episodic heat waves.

They aren't related to the ones we're having now (having the same causes, having the same impact, nor having the same scrutinity). But, nonetheless, they happened, and we haven't the same ammount of details to know if they were precedeed by hot years (like we're having right now) or they happened without any anormaly in the previous winter/summer.

esailija• 3 years ago

More extreme climate events have happened before a single co2 was emitted by human machines.

You could move goal posts again and claim that we shouldn't expect completely unprecedented extreme events from climate change, just that somewhat extreme events are supposedly becoming more common than before. Even if that was true it doesn't matter because it's not convincing and undeniable.

pvaldes• 3 years ago

We all share the same atmosphere. Is very hot in Europe also.

On the other hand, all those recent "captain chainsaw" clownery laughs and BS, surprise, surprise, it has consequences and some aren't so funny. Removing trees somewhere in Brazil will affect Uruguay.
