Unchecked Human Activity Is Pushing Ecosystems Toward the Brink

ERIKA SCHELBY – The planet is facing multiple severe challenges that require our immediate attention. Putting an end to the dirty and suffocating fossil fuel emissions may be the most significant global priority, but limiting the misuse of water and restoring degraded land are also essential projects. These two actions could help put the brakes on extreme weather events and slow down mounting losses in biodiversity, biocapacity, and the economy.

‘Completely Terrifying’: Study Warns Carbon-Saturated Oceans Headed Toward Tipping Point That Could Unleash Mass Extinction Event

JULIA CONLEY – The continuous accumulation of carbon dioxide in the planet’s oceans—which shows no sign of stopping due to humanity’s relentless consumption of fossil fuels—is likely to trigger a chemical reaction in Earth’s carbon cycle similar to those which happened just before mass extinction events, according to a new study.

In an internal memo, the White House considered whether to simply ‘ignore’ federal climate research

CHRIS MOONEY and JULIET EILPERIN – White House officials last year weighed whether to simply “ignore” climate studies produced by government scientists or to instead develop “a coherent, fact-based message about climate science,” according to a memo obtained by The Washington Post. The document, drafted Sept. 18 by Michael Catanzaro, President Trump’s special assistant for domestic energy and environmental policy at the time, highlights the dilemma the administration has faced over climate change since Trump took office. Even as Trump’s deputies have worked methodically to uproot policies aimed at curbing the nation’s carbon output, the administration’s agencies continue to produce reports showing that climate change is happening, is human-driven and is a threat to the United States.

Climate Science is Nate Silver and U.S. Politics is Karl Rove

DAVID ROBERTS – Throughout this long, crazy campaign, there’s been a tension simmering between empiricists like Nate Silver and Sam Wang, who cited poll data showing Obama with a small but durable lead, and pundits who trusted their “guts” and the “narrative,” both of which indicated that Romney had all the momentum after the first debate.

Next Plutonium Space Launch Set

BRUCE GAGNON – The next plutonium enabled space mission, the Mars Science Laboratory (MSL), is scheduled to be launched from Cape Canaveral, Florida between November 25 and December 18 of this year. The MSL rover, known as “Curiosity,” will be fueled with 4.8 kilograms (10.56 pounds) of plutonium dioxide. It will be, NASA says, “the largest, most capable rover ever sent to another planet.”

When You Get a Whiff of Disaster, Pay Attention!

TOM HASTINGS — San Bruno, California, is about 12 miles south of San Francisco, near the airport. That is where the gas line ruptured and exploded into a massive fireball hundreds of feet tall, burning dozens of homes, killing at least four, and injuring many others. Residents report having gotten whiffs of gas now and then for a period beforehand.

Native Nations Respond to Climate Change Threats

VALERIE TALIMAN: Nearly 400 Native leaders, scholars, elders and Tribal College students from across the country, joined by scientists from the National Aeronautics and Space Agency (NASA) and the National Oceanic and Atmospheric Administration (NOAA), came together at a watershed gathering, the Native Peoples Native Homelands Climate Change Workshop II, to formulate a collective response to the far-reaching impacts of climate change on Native lands and communities.
