Given that we now have several years more data, we can essentially «test» the IPCC
predictions and we arrive at the conclusion (i.e., message 1) that the climate system is tracking the «worst case scenario» (or worse in the case

«We found that in years when the sea
ice extent departed strongly from the trend, such as in 2012 and 2013,
predictions failed regardless

of the century.
Although researchers have been generally successful at modelling the huge declines in Arctic sea
ice, the extent
of Antarctic sea
ice has actually increased in recent years, contrary to the
predictions of models.
A project off Greenland will tag whales with sensors to measure sea temperatures and
ice melt in hard - to - reach places, improving
predictions of sea - level rise
The IPCC's latest
prediction for sea level rise — 0.2 to 0.6 metres by 2100 — takes this
ice loss into account but it is based on the assumption that the rate
of ice loss will remain constant.
But no one knows for sure what will happen and the
prediction of a net gain
of ice in Antarctica could yet turn out to be correct.
Better modeling

«Our work provides experimental evidence for superionic
ice and shows that these

of water at those conditions.
The paleoclimate data, which included mainly changes in the oxygen isotopes
of the calcium carbonate deposits, were then compared to similar records from other caves,

In a paper published today in Nature Physics, a research team from Lawrence Livermore National Laboratory (LLNL), the University
