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

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.”

US Generates More Electricity from Renewables Than Coal for First Time Ever

In April, renewables provided 23% compared to coal’s 20% - ‘The fate of coal has been sealed. The market has spoken’

theguardian.com - by Oliver Milman - June 26, 2019

The US generated more electricity from renewable sources than coal for the first time ever in April, new federal government data has shown.

Clean energy such as solar and wind provided 23% of US electricity generation during the month, compared with coal’s 20%, according to the Energy Information Administration.

This represents the first time coal has been surpassed by energy sources that do not release pollution such as planet-heating gases.

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).

Agriculture Department Buries Studies Showing Dangers of Climate Change

The Trump administration has stopped promoting government-funded research into how higher temperatures can damage crops and pose health risks.

politico.com - by HELENA BOTTEMILLER EVICH - June 23, 2019

The Trump administration has refused to publicize dozens of government-funded studies that carry warnings about the effects of climate change, defying a longstanding practice of touting such findings by the Agriculture Department’s acclaimed in-house scientists.

The studies range from a groundbreaking discovery that rice loses vitamins in a carbon-rich environment — a potentially serious health concern for the 600 million people world-wide whose diet consists mostly of rice — to a finding that climate change could exacerbate allergy seasons to a warning to farmers about the reduction in quality of grasses important for raising cattle.

With More Storms and Rising Seas, Which U.S. Cities Should Be Saved First?

As disaster costs keep rising nationwide, a troubling new debate has become urgent: If there’s not enough money to protect every coastal community from the effects of human-caused global warming, how should we decide which ones to save first?

After three years of brutal flooding and hurricanes in the United States, there is growing consensus among policymakers and scientists that coastal areas will require significant spending to ride out future storms and rising sea levels — not in decades, but now and in the very near future. There is also a growing realization that some communities, even sizable ones, will be left behind.

After a $14-Billion Upgrade, New Orleans' Levees Are Sinking

Sea-level rise and ground subsidence will render the flood barriers inadequate in just four years

scientificamerican.com - by Thomas Frank, E&E News - April 11, 2019

The $14 billion network of levees and floodwalls that was built to protect greater New Orleans after Hurricane Katrina was a seemingly invincible bulwark against flooding.

But now, 11 months after the Army Corps of Engineers completed one of the largest public works projects in world history, the agency says the system will stop providing adequate protection in as little as four years because of rising sea levels and shrinking levees.

The growing vulnerability of the New Orleans area is forcing the Army Corps to begin assessing repair work, including raising hundreds of miles of levees and floodwalls that form a meandering earth and concrete fortress around the city and its adjacent suburbs.

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.

Rethinking Disaster Recovery After A California Town Is Leveled By Wildfire

. . . Current federal aid is emblematic of a bigger problem in the way we respond to natural disasters: Disaster strikes, emergency help is deployed, checks are cut, communities are rebuilt — even in high-risk places.  Many say that reactive response has to change.  Staying the current course will bankrupt the federal Treasury.  Communities need to build — and rebuild — smarter.  "Communities need to be aware of those risks when doing community planning and not build in very high hazard areas" . . .

Tornado Activity in the US May Have Broken a Nearly 40-Year Record

kens5.com - Associated Press and TEGNA Staff - May 29, 2019

After several quiet years, the United States was threatening to break a major record for tornado activity this week as a volatile mix of warm, moist air from the Southeast and persistent cold from the Rockies clashed and stalled over the Midwest . . .

. . . The storms Tuesday were the 12th straight day that at least eight tornadoes were reported to the National Weather Service. If the service confirms that they were tornadoes, it would break the U.S. record for most consecutive days with at least eight tornadoes in each of those days . . .

. . . Scientists also say climate change is responsible for more intense and more frequent extreme weather such as storms, droughts, floods and fires, but without extensive study they cannot directly link a single weather event to the changing climate.
