I guess that many cavers are interested in climate change, sea level fluctuations etc. Caves are a record of such. I gave sea level fluctuations some research and learned about " The Rottnest Incursion " . We tend to think things now are relatively static but alarmingly they are not. We are probably nearing the halfway point of the current interglacial era. More worrying is sea level change which can be very dramatic and quick. Around 450 AD sea levels rose some four metres around the UK in a space of seventy five years then fell back again.. You might wonder what would happen on the Thames or Somerset levels if that scenario was repeated.. Yes all due to melting arctic ice and fluctuations in solar output. Research shows that we are on track for that to happen again due to global warming and runaway factors leading to ice melt. All the driving factors are back in place. Only ten thousand years ago you could walk to France. Mind you here in Taunton it would mean a much shorter drive to the coast.
