1.5°C Paris Climate Agreement target may be too high for polar ice sheets and sea level rise

Earth may already be too hot for the survival of polar ice sheets

If Earth stays at its current levels of warming -- below policymakers’ goal of 1.5 degrees Celsius -- polar ice sheets may melt, causing seas to rise and displacing coastal communities, a study finds.

The world's ice sheets just got a dire prognosis, and coastlines will pay the price

The world's ice sheets are on course for runaway melting, leading to multiple feet of sea level rise and "catastrophic" migration away from coastlines, even if the world pulls off the miraculous and keeps global warming to within 1.5 degrees Celsius, according to new research.A group of international scientists set out to establish what a "safe limit" of warming would be for the survival of the Greenland and Antarctic ice sheets. They pored over…

By Laura Paddison, CNN The world's ice sheets are on track to melt uncontrollably, causing sea levels to rise by several meters and a "catastrophic" migration away from shores, even if the world achieves a miracle and keeps global warming below 1.5 degrees Celsius, according to new research. A group of international scientists set out to establish what a "safe limit" of warming would be for the Greenland and Antarctic ice sheets to survive. They…

The world’s ice sheets just got a terminal prognosis, and coastlines are going to pay the price

The Greenland and Antarctic ice sheets are on course for rapid retreat, even collapse, leading to multiple feet of sea level rise even if the world pulls off the miraculous and keeps global warming to within 1.5 degrees, according to new research.

Warming of +1.5 °C is too high for polar ice sheets

Mass loss from ice sheets in Greenland and Antarctica has quadrupled since the 1990s and now represents the dominant source of global mean sea-level rise from the cryosphere. This has raised concerns about their future stability and focussed attention on the global mean temperature thresholds that might trigger more rapid retreat or even collapse, with renewed calls to meet the more ambitious target of the Paris Climate Agreement and limit warmi…

Dire sea level rise likely even in a 1.5°C world: Study

PARIS: Rising seas will severely test humanity's resilience in the second half of the 21st century and beyond, even if nations defy the odds and cap global warming at the ambitious 1.5 degrees Celsius target, researchers said on Tuesday (May 20). The pace at which global oceans are rising has doubled
