Thirteen states, at least 80 mayors, and more than 100 businesses will task themselves to meet ambitious climate-change goals—with or without federal participation. The newly formed United States Climate Alliance—which so far has support from more than a dozen states including New York, California, and Massachusetts—says it will... Climate resistance grows; 3 states ally to flout Trump, commit to Paris accord
Thirteen states, at least 80 mayors, and more than 100 businesses will task themselves to meet ambitious climate-change goals—with or without federal participation.

Fulfilling a campaign pledge, President Donald Trump said yesterday that he will set in motion plans to pull the U.S. out of the Paris Climate Pact that it joined last fall. In turn, Tesla CEO Elon Musk responded that he will have to pull out of Trump's business advisory councils of CEOs and executives, which he had joined in January. Musk was... ![Electric cars dominate U.S. climate-friendly vehicles [data: U.S. EIA; map: Climate Central]](http://images.hgmsites.net/tmb/electric-cars-dominate-u-s-climate-friendly-vehicles-data-u-s-eia-map-climate-central_100608171_t.gif)
The question is a reasonable one: electric cars may be zero-emission, but what about the electricity to recharge them?

California has by far the most aggressive climate-change policies in the nation, and the state is a global leader in plans to reduce carbon-dioxide emissions. It's also the world's eighth-largest economy, with a growing population, soaring economic output, and a resolutely progressive legislature. While its zero-emission vehicle policies may get... 
Anniversaries often provide an opportunity to reflect on important past events, review what has happened since, and reflect upon the future. April 2 of this year marks the 10th anniversary of the Supreme Court ruling in Massachusetts vs EPA in which the EPA was forced to regulate carbon emissions. The passing of this anniversary was marked by an... 
On Saturday, tens of thousands of people joined a Science March in Washington, D.C., to support use of data-based science to set government policy on climate change. The day before, the U.S. Environmental Protection Agency removed detailed climate data and scientific information because it appeared to conflict with the "beliefs" of the Trump... 
The Trump administration is either having a robust internal debate on its climate positions or floundering incoherently as various interests vie for the president's attention. Its intentions for the Paris Climate Agreement that the U.S. signed last year remain entirely unclear. On Monday, Trump's EPA administrator Scott Pruitt reportedly asked a...
