I read today that sea levels are rising at 1cm per year, but that Australia sponged up to top 7mm of world sea levels in 2010 and 2011. Lake Eyre filled and my mother and her sister in law drove 6500km to see it. Eventually evaporation took the water back and it fell in the ocean but I wonder what could have been accomplished with reforestation. It might work in the sahara as well.
