Reminds me of one of the more conclusive pieces of evidence that global warming is occurring - the date cherry blossoms flower in Kyoto (https://i.imgur.com/sD4nZuh.png)

It's a cool piece of data because it's been tracked for over 1100 years. We don't have a ton of sources of information like that.

Numerlor•3mo ago
They tend to display it for blocked connections like vpns
bbrks•3mo ago
That's a tad frustrating,.since Imgur is now blocking all UK traffic. VPN is my main saviour these days for sites that don't also block the main VPN providers or data center IPs
bsimpson•3mo ago
Looks like a regression line between April 1 and May 1. The line moves around between the 11th and the 16th from the year ~850 until ~1950, but never crosses it until ~1950. The current average is about 6 days earlier (April 5th).
Mistletoe•3mo ago
After 1900, it starts nose diving.
cryptonector•3mo ago
1,100 years is not much in geological terms. In the time we had the little ice age come and go.
bigiain•3mo ago
While that's true, it's pretty relevant if you're trying to detect or measure human-caused climate changes. And particularly with respect to changes in both population growth and the effects of the industrial revolution. The planet went from having around 350 million people in 1000AD, to over 8 billion people now. We went from powering things with human and animal muscles and heating things with effectively carbon-neutral woodfires with only decades or centuries of captured carbon, to burning coal and oil releasing millions or hundreds of millions of years worth of captured carbon into the atmosphere.
port11•3mo ago
Okay, but have you looked at the chart? Because it's very clearly changing in the past century or so.

"climate change is a hoax."

"Climate change has no scientific evidence"

"Climate change is only peddled by quack researchers"

"Climate change isn't widely accepted yet"

"Climate change cannot happen as fast as research is predicting" <---- you are here

"Snow rarely happens around town anymore"

"I hope my children can vacation to Alaska to ski"

martinpw•3mo ago
That graph looks quite old - here is a more current one showing the continued decline:

We are quite literally baking the planet. First with Bitcoin mining now with AI data centers. I pray that at least the AI datacenters will be allowed to be put to good use instead of BS jobs.
Gigachad•3mo ago
We are going to bake the planet for AI Stephen Hawking videos and Twitter politics bots.
ninetyninenine•3mo ago
Ai will take over our jobs which makes it so we can’t afford ai which causes ai companies to go belly up which causes the economy to implode thereby saving the planet.
z3c0•3mo ago
..."first with Bitcoin"? Is that the narrative we're buying now? That this problem starts at Bitcoin? Not the coal-fired electrical grid fueling it?
kibwen•3mo ago
Any proof-of-work cryptocurrency is literally a system that incentivizes runaway, self-reinforcing energy consumption like no other product in human history. Bringing it into the world is the dumbest idea that any human has ever had. I hope Satoshi is ashamed of his mental lapse.
lozenge•3mo ago
Don't worry about it, as one very famous and respected climate change economist once calculated, farming only comes to 3% of global GDP.
mensetmanusman•3mo ago
Coal powered steel mills and aluminum refining are orders of magnitude more impactful.
shoobiedoo•3mo ago
The worst part about this is that the motorcyclists stay out longer and longer until it gets below 10 degrees. I live in the "quiet countryside" and all I hear on the weekends, holidays, and often Monday/Tuesday is over the top loud motorbikes racing past my house.
monster_truck•3mo ago

brendoelfrendo•3mo ago
You should try riding, it's fun.
shoobiedoo•3mo ago
I'd love to to try a motorcycle that doesn't disturb people for at least a half kilometre around me while I wear comfy ear protection, sure. Unfortunately that isn't anywhere close to the norm in Japan
bigiain•3mo ago
Those motorcycles definitely exist, and are pretty much just as much fun to ride as the noisy ones - except for the extrovert, obnoxious, or insecure riders who _need_ noisy exhausts.

At least here in Australia, any new bike you buy off a dealership has to meet the noise regulations, and under normal use they're almost as quiet as modern cars. The noisy ones you hear are all modified or old, perhaps both (a bike needs to be pre 1972 in Australia to be completely exempt from modern noise restrictions.)

There are even fully electric motorcycles available, but they're really not prime time "just go down to a dealer and buy one, and get it serviced everywhere" ready yet.

(Full disclosure, 2 or my 5 motorcycles have noisy exhausts. Not "hear from half a kilometer away" loud, but technically illegally loud and definitely loud enough that I take extra care arriving or departing home very late or early, out of respect for my neighbors. Interestingly for this discussion, the 3 bikes with quiet, factory stock, 100% road legal exhausts are all Japanese - in fact all Hondas. The noisy bikes are both Italian - a Ducati and a Cagiva.)

shoobiedoo•3mo ago
It's just "one of those things about Japan" that, since citizens don't bring it up, foreigners aren't really allowed to either.

I'm just a little salty because I just went to two baseball games in kumamoto where my son was playing, and there were motorbikes somewhere, just doing laps I guess, for four hours straight. Everyone had to raise their voices when talking. I couldn't see any bikes, or even any well paved roads around the park. Just four hours straight of noise.

I will never understand why that is perfectly okay but talking loud in a restaurant will get you fired and ostracized. shrug cultural stuff I guess

lyall•3mo ago
I agree, the worst part about climate change is motorcyclists riding past this guy's house.

global warming is also causing an increase in the "wet-bulb temperature" [0]

> Given the body's vital requirement to maintain a core temperature of approximately 37 °C (99 °F), a sustained wet-bulb temperature exceeding 35 °C (95 °F) — equivalent to a heat index of 71 °C (160 °F) — is likely to be fatal even to fit and healthy people, semi-nude in the shade and next to a fan; at this temperature human bodies switch from shedding heat to the environment, to gaining heat from it.

in those conditions, your body can no longer cool itself down by sweating and having the sweat evaporate. simply being outside, or inside without air-conditioning, will result in potentially fatal hyperthermia.

but I'm sorry to hear that there's motorcycles driving past your house.

rester324•3mo ago
I wouldn't say it's the worst part, but it's definitely a common disturbance in japan that these idiots called bousouzoku ride around in quiet neighborhoods with their mufflers modified that they are screaming as loud or exceeding 110 but sometimes even 110 db.

And they really look like idiots when for example I easily pass them on my road bike in the Shonan area on road 134 because the roads are too narrow there to pass any cars even on a motorbike (mostly just the roadbikes are able to pass there), and they are just inching forward in the traffic with 2 km/h while revving their engines. Absolute losers.

And the longer summer definitely encourages these idiots to be a nuisance longer

johnnienaked•3mo ago
Shareholder value must increase, planet be damned.
Aeolun•3mo ago
Can confirm. 12th Oct in Tokyo, is 23 degrees (celsius) out.

It’d be nice if it didn’t mean the rest of summer is hotter too.

yayo1•3mo ago
I'm sorry, but it will obviously do, especially in Tokyo. Tokyo is experiencing a serious urban heat island effect, which is exacerbated by an increase in sources of exhaust heat.
thenthenthen•3mo ago
I am in Shanghai and it is 33 c… on 12 OCTOBER. Very bizarre.
ggm•3mo ago
Summer is an overloaded word. The solstice doesn't change. What changes, is the temperature and thus climate, out of sync with the longer baseline. Lunar calendars don't generally inform plant behaviour as strongly as temperature but day/night cycle time isn't changing while temperature is, and that may play havoc with wildlife and plants which depend on aspects of day/night cycle for best breeding outcomes.
tmtvl•3mo ago
Typo in the submission that isn't in the original (or which has been fixed in the original): researchers instead of 'resaerchers'.
