Study touts planting 1 trillion trees as most effective climate change solution

The cheapest way to halt the effects of climate change could be planting 1 trillion trees, according to a new study.

The study in the journal Science, first reported by The Associated Press, found that planting trees could be the most effective way to remove carbon from the atmosphere, but cautioned that it would have little effect without a reduction of emissions around the globe.

“This is by far — by thousands of times — the cheapest climate change solution” study co-author Thomas Crowther, an ecologist at the Swiss Federal Institute of Technology, said.

“It’s certainly a monumental challenge, which is exactly the scale of the problem of climate change,” he added.

Though, Crowther cautioned, “None of this works without emissions cuts."

Scientists with the United Nations have called for a major reduction in carbon emissions over the next decade to stave off the worst effects of climate change, including rising sea levels and dangerous weather phenomena.
