But in the future this won’t seem so bad — compared to the 1.5°C-heated planet. If we get to 2°C …&lt;p&gt;A friend said something to me a while ago that I cannot get out of my head when people are complaining about a heat wave again: Think not so much that this summer is one of the hottest in the last, but one of the coolest in the next hundred years.&lt;p&gt;I am tempted to replace 100 by 650 to match the article, or just talk about &amp;quot;the past&amp;quot; and &amp;quot;the future&amp;quot;. But a hundred years makes it more tangible for me. My late grandparents were born just a little over 100 years ago, and my youngest niece and nephew may live to see the next 100 years.</text></comment>

The thing is that people selected for different things in grape harvests over different eras. The style of wine for Bordeaux &amp;quot;Claret&amp;quot; back in the 17th century for example was a very light ruby coloured wine. Now the typical Bordeaux is a very dark and extracted product. And consumers in general are often seeking out higher alcohol &amp;quot;hotter&amp;quot; wines, partially out of the influence of new world wines.&lt;p&gt;So there could be more compounding factors in grape picking dates. Though in general seeking out a darker and higher Brix product would mean &lt;i&gt;later&lt;/i&gt; picking dates, not earlier.&lt;p&gt;But grape varieties planted have also changed somewhat overtime, too. Not so much in Burgundy where this article is talking about, though, so TFA&amp;#x27;s Beaune is actually a good choice as a point to compare.</text></comment>
