Climate Change-ocean sea levels
Last week, I think, a newspaper had a clear article about rising sea levels.
The water level rise in Sydney Harbour in summer is partly due to water expanding as it heats up and partly due to an annual tide.
Arctic ice melting doesn't change sea levels because the Arctic ice is already floating in the ocean. It is land ice melting that raises sea levels eg Greenland,Antarctica.
The current icy winter in Europe doesn't cancel out the hot weather in the Southern Hemisphere say climate change supporters
