Yes, We Can Do 'Sound' Climate Science Even Though It's Projecting the Future

Increasingly in the current U.S. administration and Congress, questions have been raised about the use of proper scientific methods and accusations have been made about using flawed approaches. The Conversation

This is especially the case with regard to climate science, as evidenced by the hearing of the House Committee on Science, Space and Technology, chaired by Lamar Smith, on March 29, 2017.

Climate Politics: Environmentalists Need to Think Globally, But Act Locally

As President Trump pivots from a failed attempt to overhaul health care to new orders rolling back controls on carbon pollution, environmentalists are preparing for an intense fight. We study environmental politics, and believe the health care debate holds an important lesson for green advocates: Policies that create concrete benefits for specific constituencies are hard to discontinue.

Opinion polls and hostile audiences at Republican legislators’ town hall meetings show that the Affordable Care Act won public support by extending health insurance to the uninsured. And this constituency is not shy about defending its gains.

The same lesson can be applied to environmental issues. In our view, environmentalists need to defend environmental regulations by emphasizing their concrete benefits for well-defined constituencies, and mobilize those groups to protect their gains.

Trump's Energy and Climate Change Order: Seven Essential Reads

Editor’s note: The following is a roundup of archival stories. The Conversation

On March 28 President Trump signed an executive order that launched a broad assault on policies put in place by the Obama administration to reduce carbon pollution. Trump’s order directs the Environmental Protection Agency to withdraw and rewrite the Clean Power Plan, which limits carbon emissions from coal-fired power plants. It also eliminates a number of other policies related to cutting greenhouse gas emissions.

Our experts explain the policies under assault and the impacts of this about-face.

Does 'Green Energy' Have Hidden Health and Environmental Costs?

There are a number of available low-carbon technologies to generate electricity. But are they really better than fossil fuels and nuclear power?

To answer that question, one needs to compare not just the emissions of different power sources but also the health benefits and the threats to ecosystems of green energy.

President Trump is expected to issue an executive order soon to reverse Obama-era rules to cut carbon pollution, including a moratorium on leasing public lands for coal mining and a plan to reduce carbon emissions from power plants.

Trump and his appointees argue that these steps will bring coal miners’ jobs back (although coal industry job losses reflect competition from cheap natural gas, not regulations that have yet to take effect). But they ignore the fact that mitigating climate change will produce large economic gains.

Brain Drain: Engineers and Managers Flee Southern Company’s Troubled Kemper ‘Clean Coal’ Plant

This is a guest post by Dan Zegart of the Climate Investigations Center

With builder Southern Company still promising that the Kemper power plant will go online soon, a group of key engineers and managers who work on the plant's so-far-inoperable gasifier has left the company.

Earlier this month, Southern Company posted a cluster of want ads on its web site for a “gasification owner,”  a “refinery technician-mechanic,” a “refinery technician-entry level,” and a “gasification technician.”

Those four positions are located at the gasification island, home to the patented TRIG technology developed by Southern Company and Kellogg Brown & Root that is supposed to turn lignite coal from an adjacent mine into a cleaner burning syngas to produce electricity.  The project's twin gasifiers, however, have been troubled by frequent shutdowns and lengthy repairs.
