A United Nations report benchmark warned on Monday warned that sufficiently caused to limit global warming by man will “require rapid, far-reaching and unprecedented changes in all sectors of society” in order to avoid dramatic consequences global, including rising sea levels, dying coral reefs and human losses due to extreme heat. to judge what is global warming to no more than 2.7º F (1.5 ° C) above the pre-industrial level, according to the Paris Agreement in 2015 – Special report – published Monday by the United Nations Group intergovernmental Panel on climate change to the limit. Scientists believe that the temperature of a turning point, can be realized in which many serious effects of global warming. “Examples of actions include switching to low or no emission of energy, such as renewable energies; Changing Food Systems, such as changes in diet away from animal products high land intensity electrifying transport and green infrastructure ‘ such as buildings are greening roofs or improve energy efficiency through intelligent urban planning that will change the layout of many cities, “the report said. The report identifies climate change “an urgent and potentially irreversible threat to human societies and the planet”, and warned that a delayed effect would limit warming to make it impossible 2.7º F. “While the pace of change, the limit warming it would be required, can be found at [2.7º F], in the past, there is the scope of the necessary transitions, especially in socially and economically sustainable way, “he says the report is not a historical precedent. “The speed and scale would solve problems needs the people’s support, public intervention and private sector cooperation.” Here are stopped by the current rate of global warming some of the changes that global carbon dioxide emissions must be in order: reducing carbon dioxide emissions by 45% in 2030, must be less than 45% than they were in 2010, found the relationship. And carbon dioxide will have zero net flow 2075 – that is, the amount of carbon dioxide in the atmosphere corresponds to the amount removed. In 2050, emissions of other greenhouse gases trap heat, including methane and soot, should be about 35%, in 2010 relative rates are reduced. “The emissions would quickly across the entire company of the most important sectors, including construction, industry, transport, energy and agriculture, forestry and exploitation of lands decline,” the report said. The United States – the carbon pollution has contributed more than any other country in history – 5.6 billion tons of carbon dioxide emitted in 2010, according to the US Energy Information Administration. If the United States pursues the ratio of the 45% target, it would be 12 years old must reduce annual emissions of more than 2.5 billion tons. In 2017, carbon dioxide emissions from global energy rose to a record high. reduce scrub carbon dioxide from the air, in addition to carbon dioxide emissions, the report recommends carbon dioxide expulsion measures – including the planting of new trees and the carbon capture and storage, a process that is captured in the carbon dioxide and it prevented in the atmosphere. “You may have the most current and potential [of the carbon dioxide removal] measure a significant impact on the environment, energy, water or nutrients used on a large scale when,” the report said. Use the 85% renewable energy and stops coal with fully It changes recommended far-reaching land use, urban planning, infrastructure systems and energy consumption – “unprecedented in scope” the changes that will be the climate scientists renewable energy accounts for 70% to 85% of electricity by 2050 the use of coal should have steep decline and should be close to 0% of the world’s electricity, and only the gas’ 8%. “While acknowledging the challenges and the differences between the options and national circumstances, feasibility political, economic, social and solar technology, wind power and energy storage power have improved significantly in recent years on “the report said. “These improvements indicate a potential systemic transition in energy production.” Plant new forest equal to the size of Canada scientists recommended that up to 3 million square miles of grazing and cultivation of 1.9 million square miles of grassland areas not be converted into a maximum of 2.7 million square miles for energy crops, which can be used for the production of biofuels. This would be a little ‘smaller than the size of Australia to the ground. The report also recommends the addition of 3.9 million square miles of forests by 2050, compared to 2010 – which is about the size of Canada. “These major transitions profound challenges for the sustainable management of the various requirements are the municipal, food, feed, fiber, bio-energy, carbon storage, biodiversity and other ecosystem services,” the report noted. “Mitigation options for the demand for land is the sustainable intensification of the soil, restoring ecosystems and the changes unless limit resource-intensive diets.” Correction: October 9 The original version of this story false, the size of the additional forest must be planted, according to a United Nations Intergovernmental Panel on Climate Change report. It is 3.9 million square miles, not 3.9 square miles.
That’s what humanity must do immediately to prevent catastrophic climate change, according to the report of the United Nations in New
