Restoring Forests Could Help Put a Brake on Global Warming, Study Finds

           

This is where the world could support new forests. The map excludes existing forests, urban areas, and agricultural lands. J. BASTIN, ET. AL., SCIENCE 365, 76, 2019

nytimes.com - by Somini Sengupta - April 25, 2019

. . . What if we grew new forests on vacant city lots, old industrial buildings — even golf courses?

For the first time, scientists have sought to quantify this thought experiment. How many trees could be planted on every available parcel of land on Earth, where they could go, and what impact could that have on our survival?

They concluded that the planet could support nearly 2.5 billion additional acres of forest without shrinking our cities and farms, and that those additional trees, when they mature, could store a whole lot of the extra carbon — 200 gigatons of carbon, to be precise — generated by industrial activity over the last 150 years.

Parts of the study — led by researchers at ETH Zurich, a university that specializes in science, technology and engineering — were immediately criticized.

Scientists Predict Climate Change Will Make Dangerous Heat Waves Far More Common

time.com - by Jamie Ducharme - July 16, 2019

People all across the U.S. have been sweating through heat waves this summer, and new research suggests they should get used to it.

Over the next century, climate change will likely make extreme heat conditions—and their concordant health risks—much more frequent in nearly every part of the U.S., according to a paper published in the journal Environmental Research Communications. By the end of the century, it says, parts of the Gulf Coast states could experience more than 120 days per year that feel like they top 100°F.

We have 18 months to save world, Prince Charles warns Commonwealth leaders

princeofwales.gov.uk - July 11, 2019

. . . The next 18 months will see critical meetings that will collectively determine the global agenda for the coming decade. And these, again, as you know better than I, range from the UNSG’s Climate Action Summit this September, to the UN Convention on Biological Diversity Conference of Parties in China next October, to the UNFCCC Conference of Parties to be held, I hope, in London that Autumn. Next year’s Commonwealth Heads of Government meeting stands of course at a pivotal point in the middle of these events and will be an absolutely vital moment to consolidate consensus on the way forward, not least of which, will be the deliberations on how to increase the amount of private sector finance flowing towards supporting sustainable development throughout the Commonwealth.

The Deep Adaptation Agenda

. . . The paper, published in July of 2018, concludes “…recent research suggests that human societies will experience disruptions to their basic functioning within less than ten years due to climate stress.  Such disruptions include increased levels of malnutrition, starvation, disease, civil conflict and war – and will not avoid affluent nations. This situation makes redundant the reformist[2] approach to sustainable development and related fields of corporate sustainability. Instead, a new approach which explores how to reduce harm and not make matters worse is important to develop. In support of that challenging, and ultimately personal process, understanding a ‘deep adaptation agenda’ may be useful.”

Climate Change Isn't Our Only Existential Threat

cnn.com - by Ira Helfand - July 6, 2019

America confronts a long list of critical problems and they all require urgent attention. But among them, two issues stand out: catastrophic climate change and nuclear war are unique in the threat they pose to the very survival of human civilization. The enormity and imminence of these twin existential threats cannot be overstated and how to confront them must be the central issue of any presidential campaign.

United Nations Says World May Face 'Climate Apartheid' that Pushes Over 120 Million Into Poverty by 2030

thehill.com - by Justin Wise - June 30, 2019

A United Nations report is warning that the world is risking a "climate apartheid" scenario in which the wealthy can pay to avoid the consequences of global warming while the rest of society suffers. 

“Even if current targets are met, tens of millions will be impoverished, leading to widespread displacement and hunger,” U.N. special rapporteur on extreme poverty and human rights, Philip Alston, said in a report released last week.

The report says that extreme climate change threatens to push "more than 120 million more people into poverty by 2030," according to Alston, who added that it will "have the most severe impact in poor countries, regions, and the places poor people live and work.”

European Heat Wave: France, Germany, Poland and the Czech Republic Set June Records, and the Worst Is Still To Come

washingtonpost.com - by Ian Livingston - June 26, 2019

A ferocious heat wave has overtaken parts of Europe. A number of records have already been broken, and there are several days of extreme heat to go.

As the heat wave escalates toward its peak late this week, temperatures have already neared or surpassed 100 degrees (37.8 degrees Celsius) in parts of France, Germany, Poland and Spain. Even Switzerland has seen locations rise toward the mid-90s.

Here’s How AI Can Help Fight Climate Change According to the Field’s Top Thinkers

From monitoring deforestation to designing low-carbon materials

theverge.com - by James Vincent - June 25, 2019

The AI renaissance of recent years has led many to ask how this technology can help with one of the greatest threats facing humanity: climate change. A new research paper authored by some of the field’s best-known thinkers aims to answer this question, giving a number of examples of how machine learning could help prevent human destruction.

The suggested use-cases are varied, ranging from using AI and satellite imagery to better monitor deforestation, to developing new materials that can replace steel and cement (the production of which accounts for nine percent of global green house gas emissions).

Scientists Shocked by Arctic Permafrost Thawing 70 Years Sooner than Predicted

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.

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

CLICK HERE - STUDY - PNAS - Ice sheet contributions to future sea-level rise from structured expert judgment

cnn.com - by Sareena Dayaram - May 21, 2019

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.
