ion on Climate Change. Science and research played a critical role in identifying and understanding the drivers and impacts of climate change and they are key in delivering solutions to address it. This Collection draws together content from across the Nature Portfolio that discusses solutions to challenges in mitigation, adaptation and finance — key pillars for COP26. The Collection also presents four Q&As with advisors and decision-makers from different parts of the globe on the science–policy interface and their hopes for COP26.

ls into a double-edged sword. Although our actions have lifted our civilization to new heights, it has come at a tremendous price. We are now at a point where humanity's demands for natural resources far exceed the earth's capacity to sustain us. The extraction and the use of those resources in the past two centuries have changed our climate and ecosystems so significantly, that a new geological era had to be created.…
ETH Zurich has published a study in the journal Science that shows this would be the most effective method to combat climate change.
The Crowther Lab at ETH Zurich investigates nature-based solutions to climate change. In their latest study, the researchers showed for the first time where in the world new trees could grow and how much carbon they would store.
Study lead author and postdoc at the Crowther Lab Jean-François Bastin explains: “One aspect was of particular importance to us as we did the calculations: we excluded cities or agricultural areas from the total restoration potential as these areas are needed for human life.”
The researchers calculated that under the current climate conditions, Earth’s land could support 4.4 billion hectares of continuous tree cover. That is 1.6 billion more than the currently existing 2.8 billion hectares. Of these 1.6 billion hectares, 0.9 billion hectares fulfill the criterion of not being used by humans. This means that there is currently an area of the size of the US available for tree restoration. Once mature, these new forests could store 205 billion tonnes of carbon: about two thirds of the 300 billion tonnes of carbon that has been released into the atmosphere as a result of human activity since the Industrial Revolution.

themselves. They should therefore reimburse countries who are suffering most from climate change. Such “loss and damage” claims include Pakistan’s recent $30bn bill for its flooding.
Hopes were raised that a deal might be in the offing but confusion surrounds details of the agreement. “The one bright spot at Cop27 has been a renewed seriousness around loss and damage, with hundreds of millions committed via various schemes,” said geographer Laurie Parsons, from Royal Holloway, London University. “Major concerns remain, however. The total funding required for adaptation is at least $2.5 trillion by 2030, so we are still orders of magnitude out.”
