A new study involving IIASA research has now estimated how much sea levels will rise as a result of
peak emission delays.

«Every
delay in
peaking emissions by five years between 2020 and 2035 could mean an additional 20 cms of sea level rise in the end,» said Matthias Mengel from the Potsdam Institute for Climate Impact Research.
The relationship between cumulative
emissions and
peak warming allows us to show how
delaying mitigation in the short term creates the need for more rapid
emission reductions later, in order to stay below a given cumulative
emissions limit.
A recent report by the German Advisory Council on Global Change (WGBU) assessed what it would take to have a good chance of remaining within the 2ºC guardrail.25 The study concluded that even a
delay in the
peaking year to 2015 means that global
emissions must fall at a rate close to 5 per cent per annum.
Other countries, like the US and India, want to
delay even discussing a deal until then, leaving scant time to the desired
emissions peak in 2020.
Delaying the
peak year even further to 2020 could necessitate global
emissions reduction rates of up to 9 % per year — i.e. reductions on an almost inconceivable scale, entailing technological feats and social sacrifices on a scale comparable to those of the Allied mobilization during the Second World War.26
And earlier this week, another study concluded that — much like today's decisions will determine the fate of West Antarctica — decisions made today about whether or not to curb
emissions will have clear repercussions in future sea level rise: For each five - year
delay in «
peaking» global carbon
emissions, median estimates for sea level rise in 2300 go up by 20 centimeters.
