Understanding Sea Level Rise, p4: ice sheet dynamics and (13) melting feedbacks – a background to 21st century SLR acceleration

In 2016 two influential new publications raised the possibility of a rapid acceleration of sea level rise in the 21st century – to ±2 metres (DeConto & Pollard) or more (2-5m, Hansen et al). In this background article we take … Continue reading

Understanding Sea Level Rise, p3: it’s about timescales, speed of change & carbon budget – world aims for 29-55m sea level rise

In our previous article of the series we’ve looked at an overview of global sea level rise forecasts for the year 2100 – and seen that these forecasts have a very large spread, and also seem to increase with time … Continue reading

Understanding Sea Level Rise, p2: A short chronology of SLR forecasts for the year 2100 (showing they increase with time)

Sea level rise is a slow process. Other consequences of climate change are generally felt much sooner. But there is something odd about the forecasts. They seem to be catching up with us, bringing a distant future closer to our … Continue reading
