Excerpts from recent editorials in newspapers in the United States and abroad:

From the June 3 Boston Globe:

The new regulations on power plant emissions announced yesterday by President Obama’s Environmental Protection Agency mark the nation’s first truly serious assault on climate change. The proposed rules, which will be subject to a four-month comment period, call for cutting carbon emissions from existing power plants by 30 percent within 15 years.

It’s a workable, realistic goal that will spur investment in low-emission energy technology, including wind and solar power. Phased in over a long enough period to minimize economic damage, it would nonetheless achieve a reduction in carbon emissions equivalent to taking nearly two-thirds of the nation’s passenger vehicles off the road. The clearer air should save thousands of lives and tens of billions of dollars in health benefits. And it would finally give the United States the credibility to push other countries, including fast-growing, fast-polluting China, to enact similar measures. It is, in every sense, a major step ”“ and a long overdue and welcome one.

Almost all credible reports suggest the world is passing the point where it can reverse, or eliminate, global warming. But that only means it’s more urgent than ever to push for historic carbon reductions. Nonetheless, many politicians ”“ including the usual global-warming deniers and those from both parties in fossil-fuel-producing states ”“ rushed to claim the new rules would cause steep economic damage.
