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.

That graph looks quite old - here is a more current one showing the continued decline:

Looks like the 20 year average is around 2 April.

1,100 years is not much in geological terms. In the time we had the little ice age come and go.

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.

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

They tend to display it for blocked connections like vpns

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

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).

After 1900, it starts nose diving.
