Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

A team from the University of Alaska Fairbanks said they were astounded by how quickly a succession of unusually hot summers had destabilised the upper layers of giant subterranean ice blocks that had been frozen solid for millennia.

 . . . Since Hurricane Maria struck in 2017, the tiny island of Dominica is rebuilding with the aim of becoming the first climate resilient and 100% sustainable nation in the world . . . Dominica can unlock the DNA of resilience through the vernacular building practices and rich cultural history of the Kalinago people that first inhabited the island . . .

 . . . Rediscovering these historic threads of resilience have been key to developing new master plans for the territory under the Kalinago Institute for Resilience and Regeneration (KIRR), founded by my team together with leading experts and community leaders, including members of the Kalinago council of chiefs, Nichie Louis Patrick Hill and Dr. Michael McDonald. Its mission is to create a thriving Kalinago Territory as a low carbon, resilient region where citizens can live and excel within the carrying capacity of its ecosystems for multiple generations into the future.

Sea Levels May Rise Much Faster Than Previously Predicted, Swamping Coastal Cities Such as Shanghai, Study Finds

Global sea levels could rise more than two meters (6.6 feet) by the end of this century if emissions continue unchecked, swamping major cities such as New York and Shanghai and displacing up to 187 million people, a new study warns.

The study, which was released Monday, says sea levels may rise much faster than previously estimated due to the accelerating melting of ice sheets in both Greenland and Antarctica.

The international researchers predict that in the worst case scenario under which global temperatures increase by 5 degrees Celsius (9 degrees Fahrenheit) by 2100, sea levels could rise by more than two meters (6.6 feet) in the same period -- double the upper limit outlined by the UN climate science panel's last major report.

European Union Nations are Living Far Beyond the Earth's Means: Report

CLICK HERE - EU Overshoot Day - Living Beyond Nature’s Limits - May 10, 2019 (19 page .PDF report)

reuters.com - by Jan Strupczewski - May 8, 2019

The European Union’s 28 countries consume the Earth’s resources much faster than they can be renewed, and none of them has sustainable consumption policies, a report released on Thursday said, as EU leaders meet to discuss priorities for the next five years.

“All EU countries are living beyond the means of our planet.

The EU and its citizens are currently using twice more than the EU ecosystems can renew,” the report by the World Wide Fund (WWF) and Global Footprint Network said.

The bonds that hold nature together may be at risk of unraveling from deforestation, overfishing, development, and other human activities, a landmark United Nations report warns. Thanks to human pressures, one million species may be pushed to extinction in the next few years, with serious consequences for human beings as well as the rest of life on Earth.

“The evidence is crystal clear: Nature is in trouble. Therefore we are in trouble" . . .

Melting Permafrost in Arctic Will Have $70tn Climate Impact – Study

Study shows how destabilised natural systems will worsen man-made problem

theguardian.com - by Jonathan Watts - April 23, 2019

The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70tn (£54tn) to the world’s climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic.

If countries fail to improve on their Paris agreement commitments, this feedback mechanism, combined with a loss of heat-deflecting white ice, will cause a near 5% amplification of global warming and its associated costs, says the paper, which was published on Tuesday in Nature Communications.

Greenland is Melting Even Faster Than Experts Thought, Study Finds

Climate change is eliminating giant chunks of ice from Greenland at such a speed that the melt has already made a significant contribution to sea level rise, according to a new study. With global warming, the island will lose much more, threatening coastal cities around the world.

Forty percent to 50% of the planet's population is in cities that are vulnerable to sea rise, and the study published Monday in the Proceedings of the National Academy of Sciences is bad news for places like New York, Miami, Los Angeles, Tokyo and Mumbai.

This Scientist Thinks She Has the Key to Curb Climate Change: Super Plants

Dr Joanne Chory hopes that genetic modifications to enhance plants’ natural carbon-fixing traits could play a key role – but knows that time is short, for her and the planet

theguardian.com - by Adam Popescu - April 16, 2019

If this were a film about humanity’s last hope before climate change wiped us out, Hollywood would be accused of flagrant typecasting. That’s because Dr Joanne Chory is too perfect for the role to be believable.

The esteemed scientist – who has long banged the climate drum and now leads a project that could lower the Earth’s temperature – is perhaps the world’s leading botanist and is on the cusp of something so big that it could truly change our planet.

She’s also a woman in her 60s who is fighting a disease sapping her very life.

Dozens of Countries Have Been Working to Plant ‘Great Green Wall’ – and It’s Holding Back Poverty

goodnewsnetwork.org - by McKinley Corbley - Mar 31, 2019

More than 20 African countries have joined together in an international mission to plant a massive wall of trees running across the continent – and after a little over a decade of work, it has reaped great success.

The tree-planting project, which has been dubbed The Great Green Wall of Africa, stretches across roughly 6,000 miles (8,000 kilometers) of terrain at the southern edge of the Sahara desert, a region known as the Sahel.

The region was once a lush oasis of greenery and foliage back in the 1970s, but the combined forces of population growth, unsustainable land management, and climate change turned the area into a barren and degraded swath of land . . .
