Most of the doomsday predictions across the globe involve the oceans finally taking over land and if NASA’s latest reports are indeed true, that day may not be far off!
A NASA study looking at 40 years of ground, airplane and satellite data shows that the West Antarctic ice sheet is melting at a rate that is far above the normal projections and the damage done here is irreversible.
The West Antarctic-underbelly is indeed melting at a rate much greater than predicted by most climate change experts and NASA reveals that it might already be too late to avert future disasters.
While the process was started by carbon emissions and ozone depletion, it seems like a simple cut back in these will not stop it melting completely.
Scientists say that the West Antarctic ice sheet has already gone beyond the threshold point of disintegration and current reduction on carbon emissions can only help slow the melting down, but not stop it entirely.
“It does seem to be happening quickly and the system is in sort of a chain reaction that is unstoppable.
Every process in this reaction is feeding the next one,” said University of Washington glaciologist Ian Joughin, lead author of one study.
This is because the grounding line that stops these gigantic glaciers from complete damage has been already breached.
The team concentrated on the Thwaites glacier that has a huge impact on all the others around it and found that the ground data backed the satellite images.
This means the next few decades could see a surge in sea levels that will threaten low-lying areas across the globe even more.
