Ice and ocean levels will rise and fall as they have done throughout the geological history of the planet (of billion years, not decades or centuries). Ocean levels have not had any significant change probably since the formation of the Mediterranean sea. As for glaciers, they are retreating since the end of the ice age. So, nothing new, they were already retreating.
I won't even mention carbon because any high school kid should be able to debunk this ridiculous hypothesis that has already been debunked countless times and is only used to sell cause sensationalist debates, sell useless papers, deviate research money, keep peer review journals alive and provide excuse for expensive meetings in exotic places.
For those who will reply to this I recommend first to spend a night in a desert with only a tank of CO2 to protect from the cold. If you do get back, I would love to talk.
