Sea levels have been rising and falling without any help from humans for as long as Earth’s oceans have existed.


Sea Levels are Never Still - Watts Up With That?

The fastest and most alarming sea changes to affect mankind occurred at the end of the Pleistocene Ice Age. Seas rose about 130m about 12,000 years ago, at times rising at five metres per century. Sea levels then fell as ice sheet and glaciers grew in the recent Little Ice Age – some Roman ports used during the Roman Warm Era are now far from the sea even though sea levels have recovered somewhat during the Modern Warm Era....

King Canute showed his nobles that no man can hold back the rising sea. It’s time the climate alarmists learned Canute’s lesson and focussed on real world problems.

Even if we ceased using all carbon fuels for electricity and transport, no one could measure the effect of that huge sacrifice on global sea levels.

Active Volcano Found Under Antarctic Ice: Eruption Could Raise Sea Levels... Inevitable eruption will speed up ice loss on frozen continent, study says. - National Geographic

"This volcanic complex has been operating for millions of years ... There have been past eruptions of this system and the ice has survived for millions of years, [so] future eruptions alone will not cause the ice sheet to fail."
