Sea level rise and melting polar ice sheets may not cause a climate catastrophe, but they will certainly change weather patterns unpredictably.
LONDON, 15 February, 2019 The global weather is about to get worse. The melting polar ice sheets will mean
rainfall and windstorms could become more violent, and hot spells and ice storms could become more extreme.
This is because the ice sheets of Greenland and Antarctica are melting, to affect what were once stable ocean currents and airflow patterns around the globe.
Planetary surface temperatures could rise by 3°C or even 4°C by the end of the century. Global sea levels will rise in ways that would enhance global temperature variability, but this might not be as high as earlier studies have predicted. That is because
the ice cliffs of Antarctica might not be so much at risk of disastrous collapse that would set the glaciers accelerating to the sea.
The latest revision of evidence from the melting ice sheets in two hemispheres and there is plenty of evidence that
melting is happening at ever greater rates is based on two studies of what could happen to the worlds greatest reservoirs of frozen freshwater if nations pursue current policies, fossil fuel combustion continues to increase, and global average temperatures creep up to unprecedented levels.
