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 →
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 →
That would likely mean that also the official UN climate goal of limiting the average world temperature rise to no more than 2 degrees Celsius – a target linked to 450 ppm CO2 equivalent stabilisation scenarios (practically ambitious, theoretically weak) … Continue reading →
If you are interested in sea level rise news, you have a busy week. First we learn from a Nature Climate Change publication that the Greenland ice sheet is already gone. Then earlier today two studies published in Environmental Research … Continue reading →
To notice something is going on with the world’s ice sheets, you could measure melting water runoff, glacier retreat or use satellites and GPS to measure ice volume decline. Just like measuring sea level rise and temperature this all adds … Continue reading →
Glacials and interglacials on the northern and southern hemisphere somehow do not seem to correspond. This has led to a ‘thermal bipolar seesaw theory,’ whereby an off-mode in the thermohaline circulation leads to an ice age in Europe, but excess … Continue reading →
Researchers of Utrecht University say the Greenland ice sheet may be more stable now than during the Eemian, the previous interglacial period, which lasted from 130,000-114,000 years BP. It turns out back then Arctic insolation was bigger – although still … Continue reading →
Icelandic scientists say they have discovered a new overturning site, where cold, dense, deep water is formed and transported through a separate route towards the Denmark Strait and further south into the Atlantic Ocean.
