To avert the worst climate change impacts, old forests and their massive carbon reserves must be protected.

In Paris last December, the world turned a major corner on climate change. Some 195 nations agreed on the urgency of the threat. They also agreed to take steps to combat it, including promoting forest protection and reforestation — steps that are necessary, though not in themselves sufficient, if we are to avoid consequences as extreme for our economies and health as they are for the environment.

President Obama deserves much of the credit for this progress. On his watch, the United States has cut greenhouse gas emissions more than any other country. He has become a powerful voice at home and abroad for doing everything possible to cut emissions. And he is showing global leadership in policy areas that go beyond the Paris agreement; for instance, he has ordered an overhaul of the federal coal-leasing program, which produces a tenth of all carbon dioxide emitted by U.S. sources.

So it was a surprise to see the U.S. Forest Service — as if in a time warp — recently working counter to that approach in the vast Tongass National Forest of southeast Alaska. There, the agency plans to continue liquidating carbon-laden old growth for at least another decade and a half.

Forest conservation is only one corner in the race to stem climate disruption that the Paris agreement, though broadly encouraging, did not get us far enough around. But it’s a vital one. As Secretary of State John Kerry said recently, deforestation generates nearly a quarter of all the world’s greenhouse gas emissions.

The science is clear: If we want to keep global warming from threatening the existence of coastal areas and low-lying island nations, the world must preserve its remaining old forests and the massive carbon reserves they’ve accumulated over the centuries. The new wood we use has to come instead from sustainably managed plantations and young stands that quickly regrow and recapture the carbon they lose to logging.

Mostly, our federally managed national forests have made that change over the past 25 years. But in the wilds of Alaska, it’s a different story. In the Tongass rainforest, the Forest Service has clung to the old-school logging of some of the most biologically rich, scenically stunning and carbon-dense forests on Earth.

The 17-million-acre Tongass absorbs about 8 percent of nation’s carbon dioxide pollution from the atmosphere every year. It also teems with extraordinary wildlife, including bears, eagles, wolves and salmon.

Six years ago, Secretary of Agriculture Tom Vilsack decided that enough was enough. He announced a transition away from further logging of Tongass old growth, with the Forest Service “rapidly” implementing this change. This was met with high praise from the public and from scientists like me, but at the agency level, his initiative stalled. The Forest Service went years with no visible progress on the transition, while approving continued clear-cutting of America’s last great rainforest.

This fall, the agency released its final “transition” proposal: 16 more years of old-growth clear-cutting, and maybe more. According to one analysis, the logging proposed under the agency’s plan would release carbon dioxide emissions equivalent to about 4 million additional vehicles annually.

The agency says that neither it, nor the timber industry, can move any faster. In the Pacific Northwest, however, both transitioned to logging young forests almost overnight when courts halted access to old growth. The agency asserts that young Tongass trees growing on old clear-cuts are not yet big enough to log. In fact, though, they are older and larger than the ones that local Native corporation loggers cut and sell abroad, and small local mills say they would be happy to process these trees locally, if they could get them from the agency.

Keeping global warming below catastrophic levels is not something that can wait until we finally get around to it. We need to be doing everything we can right now. We can’t afford to spend another 16 years or more liquidating Tongass old growth and losing the carbon reserves it stores. And we certainly shouldn’t signal other countries that the vital business of saving their carbon-rich rainforests can wait for decades.

The Forest Service can and must move much faster and not undermine U.S. progress and leadership on climate change by protecting these biologically rich and most scenically stunning and carbon dense forests on Earth. It is long past the time to take the country’s biggest carbon asset off the chopping block.
