There is a broad scientific consensus that human greenhouse gas emissions – including carbon dioxide from the burning of fossil fuels and land use change – will change the planet`s climate in a way that will have serious consequences for the environment, the economy and society. Sixteen of the hottest years since 2000, including 2016, was the hottest of all. At the same time, the Arctic Winter Sea is the weakest in stratified history. The American people believe in climate change – and they are determined to address it. Indeed, research shows that the cost of climate activity far outweighs the cost of reducing carbon pollution. A recent study suggests that if the United States does not meet its climate targets in Paris, it could cost the economy up to $6 trillion in the coming decades. A lack of compliance with the NPNs currently foreseen in the agreement could reduce global GDP by more than 25% by the end of the century. Meanwhile, another study estimates that achieving – or even exceeding – the Paris targets by investing in infrastructure in clean energy and energy efficiency could have great benefits globally – about $19 trillion. Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a “hoax” perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement.
But despite the rose garden president`s statement that “we`re going out,” it`s not that simple. The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw. She`ll have to wait a year before she leaves the pact. This means that the United States could formally withdraw on November 4, 2020, the day after the presidential elections. Even a formal withdrawal would not necessarily be permanent, experts say. a future president could join us in a month. In the five decades since the first day of the earth in 1970, remarkable economic growth around the world has inevitably been accompanied by considerable environmental challenges. While enormous progress has been made in allaying fears about air and water quality, hazardous waste, species extinction and the preservation of stratospheric ozone, world leaders continue to struggle to address the threat of global climate change in the face of the constant accumulation of greenhouse gases in the atmosphere. Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent radiation from the Earth`s surface to space, creating what is called the greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the main international panel on this issue, the concentration of these thermal gases has increased significantly since pre-industrial times and has not been observed for at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40 per cent, nitrous oxide by 20 per cent and methane by 150 per cent since 1750, mainly due to the burning of dirty fossil fuels.
