Comment from where I got this:
Hey I live there, so a few things: 1. The picture is wrong, that's nowhere in Malta. 2. The actual salt pans ARE Roman. 3. Salt pans are designed to dip underwater at high tide, so they've been coming in and out of the sea since they were built lol. Climate change has altered the exact times when they are above sea level though, and very drastic climate change will mean that they will eventually remain underwater indefinitely.
Edit from @Skua's comment below, fact checking this fact check:
Not sure about that comment, since those pools really are at Sliema in Malta https://www.google.com/maps/place/Roman+baths/@35.9165797,14.5036778,73m/data=!3m1!1e3!4m14!1m7!3m6!1s0x130e453d17183bff:0x2f6d720c7897d7de!2sFond+Għadir+Beach!8m2!3d35.9155994!4d14.5047453!16s%2Fg%2F11c0r4z3k8!3m5!1s0x130e453d997aaaab:0x2aaf0dc1de0d774e!8m2!3d35.9165157!4d14.5038595!16s%2Fg%2F11sskr6_j9?entry=ttu
But according to the local council’s facebook page when it shared this photo (they didn’t take the photo), they were built during the British period https://www.facebook.com/story.php/?story_fbid=878845397617697&id=100064767334211&paipv=0&eav=AfYRGKX34jrDJ5AuxuFU5SHiG8WiLpg42yMEYXZDkFKFtbbZPeS2GXwntwik1u1PZkc&_rdr
To add context: The British period for Malta is 1814 - 1964. Most sources agree these things were made about 100 - 150 years ago, but the exact date is unsure.
This is a graph of the sea rise in the past 140 years: https://en.wikipedia.org/wiki/Sea_level_rise#/media/File:1880-_Global_average_sea_level_rise_(SLR)_-_annually.svg
Local sea rise due to global warming is around 30cm, local tides are also around 30cm.
Another issue is that chucklefucks like Jones think that sea level rise is the most pressing problem when it comes to climate change and not things we're seeing now like much more frequent intense storms, massive wildfires and a spike in heat exhaustion deaths.
You have to be a special kind of dipshit to live in Texas all your life and not notice the hurricanes are getting worse. And Alex Jones is a special kind of dipshit.
