Power Plan Sent to the Cleaners

 

EPA Administrator Scott Pruitt has started to rollback the Clean Power Plan, President Obama’s signature policy to curb carbon emissions from power plants. This move could help prolong the life of the coal industry, yet may be largely symbolic as analyses show the U.S. is ahead of schedule on emissions reduction goals.

Ancient Trees Race to the Top

 

Trees tend to move to higher, cooler habitats in response to a warming climate. Now research on two pine tree species in the western US Great Basin that can live for thousands of years demonstrates that some species move faster than others -- and it could be thousands of years before we really know how human-caused global warming has affected these enduring trees.

Rise of the Necrofauna

 

Bringing extinct species like dinosaurs back from the evolutionary graveyard has long been a science fiction story. But with new gene editing technologies, cloning and careful selective breeding, this dream of de-extinction could soon be a reality. A new book, Rise of the Necrofauna, examines real-life efforts to bring back lost species, and the ethical and cultural challenges of de-extinction.

Power to Puerto Rico: Resilient, Renewable Microgrids

 

Before Hurricane Maria devastated the island, Puerto Rico relied on an outdated, centralized power grid that burned imported fossil fuels. It will likely take months or more to restore the system, but this disaster may offer the chance to rebuild Puerto Rico’s power system with more resilience and less carbon.

Global Warming Threatens Nutrition

 

Research is finding that increased atmospheric carbon is harming staple food crops by decreasing their nutritional value. Declining levels of iron, zinc and protein could put human health at risk, especially in the developing world.

Tamed and Untamed: Close Encounters of the Animal Kind

 

The science of animal psychology is still developing and what exactly your family dogs, or wild rabbits, are thinking is a fascinating topic for two committed animal observers, Sy Montgomery and Elizabeth Marshall Thomas. Their new collaborative book of essays, Tamed and Untamed, dives into the curious mental and emotional space among creatures and humans, as they explained to host Steve Curwood, when he visited Sy Montgomery’s New Hampshire farmhouse.

Climate Departure Date

 

A group of scientists at the University of Hawaii have figured out a way to project when the climate at a given location will move outside the range of anything we’ve known in modern times. It’s sooner then you think.

Migrations Off Schedule

 

The monarch butterflies are late, the wildebeest have turned around, and the North Atlantic right whales are missing. What’s going on with the world’s great animal migrations?

Tropical Forests Now Add To Global Warming

Tropical forests have historically absorbed excess carbon dioxide, but new research indicates that these areas are now actually a net source of CO2. Both selective logging and deforestation degrade these ecosystems, releasing more carbon into the atmosphere than the remaining trees can sequester.

CO2 Boosts Photosynthesis

As carbon dioxide levels climb in the atmosphere, plants step up photosynthesis. Living on Earth’s Savannah Christiansen reports in this week’s Note on Emerging Science that the increased carbon in the air also allows vegetation to use water more efficiently.

A River Town in Transition

listen / download
Wrangell, Alaska is a small, isolated town at the mouth of the mighty Stikine River and a former a timber capital. But since the saw mills shut down in the ‘90s, the small town has reinvented itself as a tourist destination and a commercial fishing hub. Since both of these industries are dependent on the Stikine, some locals worry that a mining development upriver could put the whole town’s livelihood at risk.

...Ultimately, if we are going prevent large parts of this Earth from becoming not only inhospitable but uninhabitable in our lifetimes, we are going to have to keep some fossil fuels in the ground rather than burn them...

-- President Barack Obama, November 6, 2015 on why he declined to approve the Keystone XL Pipeline.
