Earth’s carbon dioxide levels are likely the highest they’ve been in 15 million years

We’ve entered some profoundly unfamiliar planetary territory.

Amid a backdrop of U.S. politicians still questioning whether the changing climate is attributable to humans (it is), it’s quite likely that we’ve actually boosted Earth’s carbon dioxide — a potent greenhouse gas — to the highest levels they’ve been in some 15 million years. 

The number 15 million is dramatically higher than a statistic frequently cited by geologists and climate scientists: That today’s carbon levels are the highest they’ve been on Earth in at least 800,000 years — as there’s irrefutable proof trapped in the planet’s ancient ice. Read more…

WeWork, the co-working startup that’s valued at ~$20 billion and has some 200,000 members across 200 locations globally plus nearly 6,000 staff of its own, will no long allow employees to expense meat. It will also no longer serve meat at company events. The policy shift is intended to reduce the business’ environmental impact. The new […]

Trapping carbon pollution underground for thousands of years is key to fighting climate change

sudshr47 June 12, 2018

Trapping carbon emissions deep within Earth’s crust may be a clever way to keep warming greenhouse gases from amassing in the planet’s atmosphere. 
Giant wind turbines and solar-paneled roofs are almost certainly the energy future, but until the…

EPA’s leader is open to reconsidering crucial climate assessment. That’s not good.

Scott Pruitt, the administrator of the Environmental Protection Agency (EPA), signaled in testimony before the Senate Environment and Public Works Committee on Tuesday that he is open to revisiting a bedrock scientific analysis that paved the way for his agency to regulate planet-warming greenhouse gases. If he does so, it could take the EPA entirely out of the ballgame when it comes to limiting emissions of carbon dioxide, methane, and other global warming pollutants. 

It would also set up an epic legal battle that could go on for years.

That Pruitt is willing to entertain the notion of revisiting what is known as an “endangerment finding” under the Clean Air Act tells you a lot about how Pruitt views his own agency. He has spent his first year as administrator as a kind of trojan administrator, bent on destroying the agency’s work from within. He has swiftly rolled back regulations on everything from pesticide use to methane emissions, all while downsizing the agency’s workforce to Reagan-era levels.  Read more…
