Tom Udall: It’s past time we confront the climate and nature crises

High Country News - OpED

January 31, 2020
In his 1963 book The Quiet Crisis, my father, former Interior Secretary Stewart Udall, sounded the alarm about the creeping destruction of nature. “Each generation has its own rendezvous with the land, for despite our fee titles and claims of ownership, we are all brief tenants on this planet,” he wrote. “By choice, or by default, we will carve out a land legacy for our heirs.”

Rewilding the Arctic can slow the climate crisis

Climate News Network

January 29, 2020
Releasing herds of large animals onto the tundra − rewilding the Arctic − to create vast grasslands could slow down global heating by storing carbon and preserving the permafrost, UK scientists say.

With no woolly mammoths available nowadays, the scientists, from the University of Oxford, suggest an alternative in the Philosophical Transactions of the Royal Society B − importing large herds of bison and horses to provide the mega-fauna that would prevent tree growth and create huge areas of grazing land.

Temperatures at a Florida-Size Glacier in Antarctica Alarm Scientists

The New York Times

January 29, 2020
Scientists in Antarctica have recorded, for the first time, unusually warm water beneath a glacier the size of Florida that is already melting and contributing to a rise in sea levels.

The researchers, working on the Thwaites Glacier, recorded water temperatures at the base of the ice of more than 2 degrees Celsius, or 3.6 degrees Fahrenheit, above the normal freezing point.

Trust our expertise or face catastrophe, Amazon peoples warn on environment

The Guardian

January 28, 2020
Ecosystems will continue to collapse around the world unless humanity listens to the expertise of indigenous communities on how to live alongside nature, a prominent Amazon leader has warned.

Tuntiak Katan of the Ecuadorian Shuar people, who is vice-president of the pan-Amazon organisation representing communities in the river basin, said governments were spending millions of dollars on environmental consultants while largely ignoring the land management skills of the planet’s indigenous people that could help combat the climate crisis and biodiversity loss.

Rethinking land conservation to protect species that will need to move with climate change

Phys.org

January 28, 2020
All plants and animals need suitable conditions to survive. That means a certain amount of light, a tolerable temperature range, and access to sources of food, water and shelter. Many of the existing efforts to protect plant and animal species across the United States rely on information about where these species currently live.

Climate change mitigation and nature conservation both require higher protected area targets

Philosophical Transactions of the Royal Society B - Opinion

January 27, 2020
Nations of the world have, to date, pursued nature protection and climate change mitigation and adaptation policies separately. Both efforts have failed to achieve the scale of action needed to halt biodiversity loss or mitigate climate change. […] A new target of 30% of the sea given high levels of protection from exploitation and harm by 2030 is under consideration and similar targets are being discussed for terrestrial habitats. We make the case here that these higher targets, if achieved, would make the transition to a warmer world slower and less damaging for nature and people.

Catastrophic Amazon tipping point less than 30 years away: study

Mongabay

January 23, 2020
One of the most important questions Amazon scientists are asking today is, how much deforestation and global climate change can this tropical biome tolerate before rainfall is drastically reduced — forcing a rainforest-to-savanna conversion, and releasing huge amounts of stored forest carbon into the atmosphere in the process?

A recent study tried to answer that question. The findings: the Amazon basin could be less than 30 years from a catastrophic collapse that would turn it into a dry savanna, according to a study published in the journal One Earth.

Big Business Says It Will Tackle Climate Change, but Not How or When

The New York Times

January 23, 2020
Business titans who for decades brushed off warnings about climate change arrived at the annual World Economic Forum this week ready to show their newfound enthusiasm for the cause.

Having previously played down the need for the reform that scientists had urged, finance leaders and company chiefs conspicuously rallied around a consensus that accelerating global temperatures pose a significant risk to society — and to business.
