Climate Change: UN Panel Signals Red Alert on 'Blue Planet'

bbc.com - by Matt McGrath - September 25, 2019

According to a UN panel of scientists, waters are rising, the ice is melting, and species are moving habitat due to human activities.

And the loss of permanently frozen lands threatens to unleash even more carbon, hastening the decline.

There is some guarded hope that the worst impacts can be avoided, with deep and immediate cuts to carbon emissions.

Study of Antarctic Sea Ice Collapse Warns of Potential 10-Foot Sea Rise

The faster the ocean warms, the faster key Antarctic glaciers will disintegrate.

A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.

Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.

It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.

The oceans are warming faster than previously estimated, setting a new temperature record in 2018 in a trend that is damaging marine life, scientists said on Thursday.

New measurements, aided by an international network of 3,900 floats deployed in the oceans since 2000, showed more warming since 1971 than calculated by the latest U.N. assessment of climate change in 2013, they said.

And “observational records of ocean heat content show that ocean warming is accelerating,” the authors in China and the United States wrote in the journal Science of ocean waters down to 2,000 metres (6,600 ft).

Seabed Mining Can Decide the Fate of the Deep Ocean

At the International Seabed Authority’s ocean-side headquarters, delegates from dozens of countries strolled through breezeways adorned with the works of Jamaican artists as the United Nations-chartered organization’s annual meeting began its second week. No one, however, was entering a conference room where the seabed authority’s Legal and Technical Commission (LTC) was in session and men in dark suits stood watch. A sign advised that the meeting was "closed."

Behind heavy wood doors, the 30 members of the commission convened in secret to discuss, among other things, confidential contracts issued to corporations and state-backed companies to explore and potentially mine vast, barely explored deep-sea habitats that scientists believe play a key role in the global ecosystem.

Coastal cities around the world could be devastated by 1.3m of sea level rise this century unless coal-generated electricity is virtually eliminated by 2050, according to a new paper that combines the latest understanding of Antarctica’s contribution to sea level rise and the latest emissions projection scenarios.

Unless the world stops burning fossil fuels that are fuelling global warming, irreversible changes in the Arctic could have disastrous effects for the people that live there and for the rest of the planet, researchers warned on Friday.

The Arctic's ecosystems are fundamentally threatened by climate change and other human activities, such as oil and gas extraction, they said in a report for the Arctic Council, an inter-governmental forum working to protect the region's environment.
