Sea Ice Resilience, Natural Variability Undermine Claims Of Climate Tipping Points
by Dr. David Whitehouse Feb 28, 2025
There is no shortage of people telling us that we have reached an important inflection point regarding the world’s polar sea ice sheets. [emphasis, links added]
The BBC tells us that the world’s sea ice has fallen to a record low, informing us that the Arctic end-of-summer extent fell from an average of seven million sq km in the 1980s to 4.5 million sq km in the 2010s.
It adds that on the other side of the world until the mid-2010s, Antarctic sea ice had been remarkably resilient, defying predictions that it would shrink.
Since then, however, the continent has shown a series of very low sea ice extents, although there is still lots of natural variability.
You can interrogate the data yourself and see just how variable it is.
