Antarctica

More meltdown than melting. The author reckons ‘Tackling global warming will be the central project of the 21st Century’, but the NSIDC graphic below doesn’t suggest anything alarming. No doubt the BBC will be offsetting all those supposedly wicked ‘carbon emissions’ from flying a reporter round the world. Sadly the trip only extended to West Antarctica, parts of which are close to a significant volcanic region, whereas the majority of the ice is in East Antarctica. See: Scientists discover 91 volcanoes below Antarctic ice sheet. In 2015 a NASA study reported ice gains exceeding losses in Antarctica as a whole, with the net losses being in the west and the net gains in the east.

A trip to a melting glacier will shape how the BBC’s new climate editor reports on climate change, says the BBC.

You cannot help but be awed by the scale of Antarctica, the great white continent.

I visited just before the pandemic struck and it is impossible not to feel humbled in the presence of something that seems so much bigger and more powerful than you.

But that sensation is an illusion.

When we finally flew over the front of the enormous glacier after weeks of travelling, I found myself staring down at an epic vision of shattered ice.

As I wrote at the time, it felt like I’d reached the frontline of climate change; a place where the equilibrium that has held our world in balance for thousands of years was slipping and crashing.

Satellite monitoring shows that the overall rate of ice loss from West Antarctica has increased five-fold over a 25-year period. This one glacier – Thwaite’s glacier – alone now accounts for 4% of global sea level rise.

Needless to say, this acceleration is a result of us humans polluting the air with greenhouse gases [Talkshop comment – mere assertion]. That fact [sic] explodes any impression that the ice is overwhelming. The opposite is true, we are overwhelming the ice.
