Tides ebb and flow but mean sea levels are among the constants of climate science. Scientists can at least point to higher sea levels as clear evidence that climate change is real. The rise is caused by thermal expansion (hot water expands) and by melting ice sheets. And the facts are observable: thousands of gauges, such as that shown in the image, measure tides around the world, with some records going back to the 18th century. The rise in sea levels may be accelerating.
