Water vapor injected into the stratosphere by powerful thunderstorms converts stable forms of chlorine and bromine into free radicals capable of transforming ozone molecules into oxygen, which could in turn lead to increased ozone loss and greater levels of harmful UV radiation.
The findings suggest that such an scenario - which would redraw coastlines worldwide and unleash colossal human misery - is now a distinct possibility within the next 100 years.
Past abrupt climate changes were probably a result of rapid and extensive variations in sea-ice cover.
The first evidence of a volcanic eruption from beneath Antarctica’s most rapidly changing ice sheet. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active.
We calculate that the sub-Antarctic hydrate inventory could be of the same order of magnitude as that of recent estimates made for Arctic permafrost.
There is clear evidence that the West Antarctic Ice Sheet is contributing to sea-level rise.
Ice loss from the marine-based, potentially unstable West Antarctic Ice Sheet (WAIS) contributes to current sea-level rise and may raise sea level by ≤3.3 m or even ≤5 m in the future.
As sea temps rise off Northern Queensland, more irukandji & box jellyfish are moving South.
Meteorologists are debating our role in bizarre weather events. We have the technology for change, but not the political will.
