EPA employees speak out about the agency’s problems under Trump.

Two years ago, a paper came out arguing that America could cheaply power itself on wind, water, and solar energy alone. It was a big deal. Policy makers began relying on the study. A nonprofit launched to make the vision a reality. Celebrities got on board. We named the lead author of the study, Stanford University professor Mark Jacobson, one of our Grist 50.

Now that research is under scrutiny. On Monday, 21 scientists published a paper that pointed out unrealistic assumptions in Jacobson’s analysis. For instance, Jacobson’s analysis relies on the country’s dams releasing water “equivalent to about 100 times the flow of the Mississippi River” to meet electricity demand as solar power ramps down in the evening, one of the critique’s lead authors, Ken Caldeira of the Carnegie Institution for Science, told the New York Times.

Jacobson immediately fired back, calling his critics “nuclear and fossil fuel supporters” and implying the authors had sold out to industry. This is just wrong. These guys aren’t shills.

It’s essentially a family feud, a conflict between people who otherwise share the same goals. Jacobson’s team thinks we can make a clean break from fossil fuels with renewables alone. Those critiquing his study think we need to be weaned off, with the help of nuclear, biofuels, and carbon capture.

Grist intends to take a deeper look at this subject in the coming weeks, so stay tuned.

A Fair Climate Deal? Accountability First!

Joachim Schleich, Grenoble École de Management (GEM) On June 1, U.S. President Donald Trump announced that the United States would withdraw from the Paris climate agreement, ignoring pleas from businesses (including fossil-energy heavyweights such as ExxonMobil), city mayors (including the former steel capital Pittsburgh), federal states (including the world’s sixth-largest economy, California), his own Secretary of State and Secretary of Defense, all other G7 leaders and, last but not least, the Pope. After almost two decades of tedious negotiations, the Paris Agreement (or Accord de Paris) was adopted in December 2015 by virtually every country in the world, including the U.S. The Paris Agreement’s central aim is to hold global warming well below 2 degrees Celsius and to pursue efforts to limit warming to 1.5 degrees Celsius. Unlike its predecessor, the Kyoto Protocol, the Paris Agreement not only involves greenhouse gas emission targets for developed countries but also for emerging and developing countries such as China and India. The countries that have ratified the Paris Agreement are obliged to submit a plan every five years to the United Nations stating how they intend to achieve their “nationally determined contributions” (NDCs), which are voluntary pledges to limit national greenhouse-gas emissions and to help developing countries cope with climate change. In a nutshell, President Trump essentially decided to pull his country out of a voluntary deal that has no enforcement mechanism in place, thereby snubbing the global coalition of almost 200 countries that signed the Paris Agreement, and adding stress to transatlantic diplomatic relations. Why did Donald Trump dump the Paris Agreement […]

What Is World Oceans Day Meant To Do?

Each year on June 8 we celebrate World Oceans Day, a date designated by the United Nations to recognize our relationship with the ocean through many different ways of global connection. Around the world, through the World Ocean Network, The Ocean Project, and many other organizations with ocean interests, events will take place to highlight the value of ocean resources. There will be maritime festivals and beach clean-ups, school projects and environmental presentations the world over – in Africa and Asia, Europe and the Americas. What was once a bright idea is now an international event that for one brief moment focuses some part of ephemeral world interest on the ocean and its benefit for all mankind.Of course, every day is ocean day. We can claim that with the authority of the headlines that every day point to some ocean issue of import: the crisis of plastic pollution and growing, swirling gyres around the world, the catastrophic disaster of a failed drilling rig or shipping accident, piracy in Arabian waters, the trade impacts of an expanded Panama Canal, the security implications of melting sea ice and the opening of Northern Arctic passages, the decline of fisheries across the world economy, relaxed ocean regulations and increased drilling and mining, and the continuing, growing evidence of the negative impact of climate change on the ocean and its capacity for supporting all aspects of human survival.What is World Oceans Day meant to do? If all those concerned with ocean issues were to shout at once, there would be a compelling noise, enough to let us know that others around the world also care, enough to give us confidence that our whole is greater by the sum of our individual voices, and perhaps enough to penetrate the consciousness of a political structure that for the most part continues to ignore ocean issues, willfully waiting until it is too late.

Climate Change And The Minnesota Governor’s Race

Dr. Michael Mann, the Distinguished Professor of Atmospheric Science at Penn State University and one of the nation’s top climate scientists announced that he was endorsing Minnesota State Auditor Rebecca Otto in her effort to succeed the outgoing Governor Mark Dayton in 2018. Normally, a prominent scientist’s endorsement of a gubernatorial candidate wouldn’t be that big of a deal. But with Trump’s fatally flawed decision to pull the United States out of the Paris climate agreement, and his appointment of fossil fuel industry puppets to key environmental posts (such as Scott Pruitt at the Environmental Protection Agency and Ryan Zinke at the Interior Department) climate change (and our response to it) has taken on new political significance.

Mr. Pruitt, Do The Job You Were Hired To Do

Dear Mr. Pruitt, I understand, I know with every fiber of my being, that it is for each one of us, our individual responsibility to be mindful of how we walk on the Earth, for the proverbial “footprint” we leave behind, and for the choices we make on a daily basis that will either take from, or contribute to, the well-being of the planet and our physical environment. I choose to live in Oregon in great part for the green, the vastness, and the physical beauty that is still here. For now.. […]
