Surprisingly, it found that these extra trees could be grown in croplands and urban areas, highlighting the major role agro-forestry could play in tackling climate change. Some experts who were not involved with the study, however, expressed scepticism about some of its findings. "Humans have enhanced forest cover on a large scale only by shrinking their population size (Russia), increasing the productivity of industrial agriculture (the West) or by direct order of an autocratic government (China).

The team said their study evaluated the UN claim for the first time, showing where the trees could be restored and how much carbon they could capture.Washington: Good news: we can help halt climate change through a massive campaign of reforestation, according to a new study published Thursday. The most recent report by the UN’s Intergovernmental Panel on Climate Change proposed that limiting climate change to 2."Yes, heroic reforestation can help, but it is time to stop suggesting there is a nature-based solution to ongoing fossil fuel use."Planting trees to soak up two-thirds of the entire anthropogenic carbon burden to date sounds too good to be true.2 billion acres (900 million hectares) of trees that would sequester 205 billion tonnes of carbon.Such an effort could capture two-thirds of manmade carbon emissions and reduce overall levels in the atmosphere to their lowest in almost a century, according to the research that was carried out by ETH Zurich and published in Science."None of these activities looks remotely feasible or sustainable on a global scale.5 degrees Celsius) will require up to an extra 2."Restoration of trees may be among the most effective strategies, but it is very far indeed from the best climate change solution available, and a long way behind reducing fossil fuel emissions to net zero," said Myles Allen, a geosystem science professor at Oxford.7 degrees Fahrenheit (1. The paper found that the Earth can support 2.47 billion acres of forest by 2050.The study is the first to attempt to quantify how many trees the Earth can ., where to plant them and how much carbon they could store. Bad news: it would require covering an area the size of the United States in new trees, and even then some scientists are sceptical about the papers conclusions. "We all knew restoring forests could play a part in tackling climate change, but we had no scientific understanding of what impact this could China Polyester Oxford fabric Factory make," said co-author Thomas Crowther. Martin Lukac, a professor of eغير مجاز مي باشدystem science at the University of Reading, added that one of the papers weaknesses was its reliance on overly optimistic modelling. Probably because it is," he said. There isnt. The scenario, they added, is "undoubtedly achievable under the current climate."

The researchers studied around 80,000 high-resolution satellite photographs of protected forest areas, from the arctic tundra to equatorial rainforest, to establish a "natural level" of tree cover for each eغير مجاز مي باشدystem."Our study shows clearly that forest restoration is the best climate change solution available today."."But they warned that the need for action is urgent since a warming climate was already reducing the amount of land that can support new forests. Sorry," he added.They then used machine learning to identify 10 soil and climate variables that determine tree cover in each eغير مجاز مي باشدystem and created a predictive model to map potential tree cover worldwide under current environmental conditions
