No more excuses: restoring nature is not a silver bullet for global warming, we must cut emissions outright

Restoring degraded environments, such as by planting trees, is often touted as a solution to the climate crisis. But our new research shows this, while important, is no substitute for preventing fossil fuel emissions to limit global warming.
We calculated the maximum potential for responsible nature restoration to absorb carbon dioxide in the atmosphere. And we found that, combined with ending deforestation by 2030, this could reduce global warming 0.18°C by 2100. In comparison, current pledges from countries put us on track for 1.9-2℃ warming.
This is far from what’s needed to mitigate the catastrophic impacts of climate change, and is well above the 1.5℃ goal of the Paris Agreement. And it pours cold water on the idea we can offset our way out of ongoing global warming.
The priority remains rapidly phasing out fossil fuels, which have contributed 86% of all CO₂ emissions in the past decade. Deforestation must also end, with land use, deforestation and forest degradation contributing 11% of global emissions.
Wealthy nations, such as Australia, should achieve net-zero CO₂ emissions earlier than the global average based on their higher historical emissions.
We now need new international cooperation and agreements to stop expansion of fossil fuels globally and for governments to strengthen their national climate pledges under the Paris Agreements ratcheting mechanism. Promises of carbon dioxide removals via land cannot justify delays in these necessary actions.
I’m afraid I’ve got news for you University of Melbourne academics. The Paris Agreement is dead in every way which matters. Germany and the rest of Europe are frantically scrabbling for as much coal power as they can get their hands on.
