They survived just fine during the previous Holocene warm periods, and cool periods. But, not, doom!
The barnacle, Spaniards’ favourite Christmas dish, imperilled by climate change
On the craggy rocks on northwestern Spain’s treacherous Costa da Morte (Death Coast), wetsuit-clad fishermen dodge crashing waves as they pick barnacles, a prized Christmas delicacy facing decline due to climate change and other factors.
Fetching up to 200 euros ($208) per kilogram (2.2 pounds) during the holiday season, the gooseneck barnacle from the Galicia region has long been treasured by Spaniards for both its flavour and difficulty to harvest.
However, the rise in sea temperatures driven by climate change has severely affected barnacle habitats, as they thrive in icy waters. A recent study by the University of Vigo also linked changing wave patterns to lower quality in the shellfish.
Israel Martinez, an auctioneer in the A Coruna fish market, said that there used to be double or triple the number of barnacles just 10 years ago.
One thing missing is how much the sea temperature has risen. Weird, eh? I wonder if it is any different from those previous Holocene war periods? Or, if they are over-harvesting? Meh, doesn’t matter to a cult.
How Does Climate Change Affect Christmas?
Christmas, a time of joy and tradition, is increasingly reshaped by climate change. From snowy celebrations in colder regions to tropical festivities in warmer climates, extreme weather and rising temperatures are altering how people celebrate the holiday across the globe.
Fewer White Christmases
In traditionally snowy regions, the dream of a white Christmas is fading. Warmer winters mean less snow and ice, making it harder for families to enjoy iconic activities like skating on frozen lakes.
Blah blah blah, cult.

Do you engage with climate deniers that come your way this Christmas? And if so, what’s the best way to do it?
More than 50% of youth in the United States are very or extremely worried about climate change, according to a 
U.S. President Joe Biden on Monday commuted the sentences for 37 out of 40 federal inmates on death row, converting them to life in prison without parole before he hands over power to President-elect Donald Trump on Jan. 20.
Will we have a white Christmas? The annual question reaches peak curiosity this week, but as the planet warms due to human-caused climate change, the probability of seeing snow at Christmas is becoming increasingly unlikely, recent studies and reports have shown.
