Question 4: Sea levels rose by 19cm between 1901 and 2010. How fast are they continuing to rise?
Rising at the same rate as before
No. The United Nations expected sea levels to rise by no more than 1 metre by 2100, however recent research in 2016 published in the journal ‘Nature’ states that this is too conservative, and that without decisive action to cut carbon now, “multi-meter sea level rise would become practically unavoidable, probably within 50–150 years.” This new research by noted climatologist Dr. James Hansen references a similar period in the Earth’s prehistoric past, where sea levels reached +6–9m during a period that was “no more than a few tenths of a degree warmer than today.”
Rising faster, but sea levels will rise by no more than 1 m by 2100
No. Sea levels are rising faster, and it’s true that the United Nations expected sea levels to rise by no more than 1 metre by 2100 – however, recent research in 2016 published in the journal ‘Nature’ states that this was too conservative. Without decisive action to cut carbon now, “multi-meter sea level rise would become practically unavoidable, probably within 50–150 years.” This new research by noted climatologist Dr. James Hansen references a similar period in the Earth’s prehistoric past, where sea levels reached +6–9m during a period that was “no more than a few tenths of a degree warmer than today.” 
Rising faster, with the likelihood of multi-meter rise in the next 50-150 years
Correct! The United Nations expected sea levels to rise by no more than 1 metre by 2100, however recent research in 2016 published in the journal ‘Nature’ states that this is too conservative, and that without decisive action to cut carbon now, “multi-meter sea level rise would become practically unavoidable, probably within 50–150 years.” This new research by noted climatologist Dr. James Hansen references a similar period in the Earth’s prehistoric past, where sea levels reached +6–9m during a period that was “no more than a few tenths of a degree warmer than today.”
