how many trees are needed to stop global warming?

Here are some of the changes that will need to be made in order to stop the current pace of global warming: Reduce carbon emissions by 45% By 2030, global … Key questions scientists will need to address are how global reforestation might affect Earth’s surface albedo (reflectivity) and evapotranspiration. The trillion trees initiative to reduce global warming is like someone trying to lose a lot of weight by taking daily walks without changing the daily diet. At our current rate of global emissions - around 10 billion tonnes per year, PWC's 2013 report estimated that we will exceed the "safe" limit of 2 degrees warming by 2034. But we do need to plant more trees, quickly. The Intergovernmental Panel on Climate Change (IPCC) said that if the world wanted to limit the rise to 1.5C by 2050, an extra 1bn hectares (2.4bn acres) of trees would be needed. Trees planted in tropical areas sequester an average of 22.6 Kg of carbon per annum. So far, nearly 50 countries have signed on to the commitment. Planting trees is great, but I can't help thinking we also need to stop chopping down forests in the first place. In the near term and locally, says Saatchi, forest restoration may actually have a warming effect. It is possible to sequester CO2 by planting trees on degraded land, changing farming practices, and using biochar on farms. (AP Photo/Luca Bruno) A study released on Thursday, July 4, 2019 says that the most effective way to fight global warming is to plant lots of trees - a trillion of them, maybe more. When you chop down a tree, you … Other changes have to be made to reduce global CO 2 emissions and an effective response lies in the hands of world politicians. Even if global warming is limited to 1.5 degrees Celsius, the area available for forest restoration could be reduced by a fifth by 2050 because it would be too warm for some tropical forests. But approximately 10 percent of them don’t have enough available space to restore the intended amount of trees. There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.. Quora User has an interesting answer, though it is half true. To help reach the UK government's 2050 target to become carbon net zero – that’s removing as much carbon as we’re producing – we need more trees. Global warming is caused by too many ‘greenhouse gases’ in our atmosphere – aka, gases that trap heat and warm our planet. Back in 2011, Germany launched the Bonn Challenge, a global initiative aimed at restoring 350 million hectares of trees by 2030. The #1 sector responsible for greenhouse gas emissions in the US is transportation , and cars account for 82% of this, according to the United States Environmental Protection Agency (EPA).
