The new research follows other recent studies warning of the possibility of ice sheet collapse in Antarctica and suggesting huge sea-level rises.
Here, James Hansen of the NASA Goddard Institute for Space Studies and others argued that atmospheric CO2 must be brought back to about 350 parts per million—the level it was at before around 1800 in order to avoid huge sea-level rises, crop failures and other catastrophes.
Huge sea-level rises caused by climate change will last far longer than the entire history of human civilisation to date, according to new research, unless the brief window of opportunity of the next few decades is used to cut carbon emissions drastically.
Experts say the emissions that may make a huge increase of sea level inevitable are expected to occur in just the next few decades.
Whether this growth is temporary matters, for if the sheet were to start thinning again, it would have a huge effect on global sea level.
"We have seen a huge sea change in the level of political agreement which has exceeded public expectation, particularly in delivering for the victims and the reconciliation process," Mrs Long added.
This has led to huge thermal expansion and sea level rise.
According to the scientists interviewed in the film, we have passed the tipping point and must prepare for huge coastal impacts from sea level rise.
The meteor, the researchers theorize, could have set off a devastating chain of events, including huge volcanic eruptions, changes in sea level and climatic shifts.
It doesn't take rocket science to know that a huge city that is below sea level on the Gulf Coast, where hurricanes are a yearly occurrence, needs extra-strength protection from these storms.
The eldest and I rise early and take two cable cars to the top of the Corvatsch Glacier, a huge, domed expanse 3,303m above sea level, with a foot of fresh snow on it from the night before.
