Now grapes are revealed as part of the Great Climate Hoax

Climate Change: in Vino Veritas

In truly fascinating new reasearch, scientists have searched historical records to collect data about when the grape harvest began each year. Their research wasn’t published in the Journal of French Wine (I don’t know if there even is one), it was published in the journal Climate of the Past. That’s because the date when the grape harvest begins is a clue to temperature.

The importance of clues like this is that they extend farther back in time than thermometer records. The grape harvest dates (GHD) start in the year 1354 — centuries before the thermometer was even invented. Also quite important: they are all for the same location: Beaune, France.

When the temperature is hotter, the grapes are ready to harvest earlier. When it’s colder, they harvest later. If climate is really heating up, the grape harvest should be getting earlier. And what did they find? This:

I can also estimate the trend with a smoothing function, and regular readers know I’m fond of the lowess smooth (but different methods give essentially the same result):

Those evil little round fruit are in on the conspiracy too, I tell you!

As Tamino says, the resemblance to a hockey stick is notable.

1. notice the tall spike in the early 1800s

one of only two spikes that exceeded 310 days before harvest...

I believe that would be 1816 aka The Year without Summer

the year after the eruption of Mt. Tambora in 1815.

5. Very interesting. Thanks.

6. And the spike in the mid-1300's is almost certainly the 1362 Oraefajokull eruption

2. Of course there's such a thing ! Don't be silly.

4. I was actually thinking about this yesterday.

How much CO2 is created in wine and beer (and for that matter, all liquor) production globally? Not just the farming and bottling, but in fermentation and what gets released after the bottles are opened? Is this added to the carbon footprint of countries where this production is high?
