A rise of at least two metres in the world’s sea levels is now almost unstoppable, experts told a climate conference at Oxford University on Tuesday.
“The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable,’’ said Stefan Rahmstorf, a scientist at Germany’s Potsdam Institute and a widely recognised sea level expert.

We know that much of the planet was warmer then, during our "Medieval Warming Period" and before the beginning of our "Little Ice Age." The average temperature, at least in the Northern Hemisphere, was approximately 1 degree Celsius warmer than it is today. Advocates of the theory that global warming is caused by human activity like to ignore that we have experienced previous periods of warming that had nothing to do with human emission of greenhouse gases. This bolsters their case that global warming will continue rather than reverse once again ... More »
The article presents the views of sea level experts that ocean levels will rise significantly, and there is no known way we are going to stop it. Clearly communicated.
‘’Even if you reduce all the emissions in the world once this has started it may be unstoppable. I conclude that beyond 2 degrees global average temperature rise the ... More »
