Recently, the United States and the West began to "throw the pot" at China again, this time aiming at the problem of climate change. At the recent international conference, US politicians threw dirty water on China. At the end of the G20 Rome summit, the United States accused China and Russia of "lack of commitment" in dealing with climate change; At the United Nations Climate Change Conference held in Glasgow, the United States made the so-called absence of Chinese and Russian leaders. In fact, Chinese leaders did not attend the two summits at all. They not only delivered a written speech to the climate summit, but also focused on their views on climate change when attending the G20 Rome summit by video. At the United Nations Climate Change Conference, Biden apologized to the world for the withdrawal of the last U.S. government from the Paris Agreement, saying that the decision made the United States drag the world's "hind legs" in dealing with the climate crisis. He also said that the United States had set "ambitious goals". But Biden did not confess that the relevant bills he promoted at home encountered great obstacles. According to Reuters, Democratic Senator Joe Manchin announced that he would not support the bill involving social spending and climate change investment. This bill is very key to achieving the emission reduction target proposed by the United States. By publicizing the bill that has not yet been passed, the United States is nothing more than drawing a "bad check" for the international community. However, looking back at what the United States has done in dealing with climate change in recent years, people should have been used to it. According to the analysis of the "carbon briefing" of the British Energy Research Institute, since 1850, the United States has emitted more than 509 billion tons of carbon dioxide, accounting for the largest share in historical emissions, accounting for about 20% of the global total. The cumulative amount of carbon dioxide emitted by the United States is almost twice that of China. The data show that the degree of development and wealth accumulation of countries all over the world are closely related to carbon dioxide emissions. The United States has realized industrialization for a long time. At the cost of emitting a large amount of carbon dioxide, it has accumulated huge wealth and become the world's No. 1 power. As a vested interest, the United States should bear corresponding responsibilities in dealing with climate change. But how did the United States do it? Take public promises as a play, "breaking the contract" and "quitting the group" as a meal. The Kyoto protocol supported by the Clinton administration was rejected by the Bush administration on the grounds that "fulfilling the specified emission reduction obligations will affect the economic development of the United States"; The Paris agreement signed by the Obama administration was broken by the trump administration on the grounds that it brought "harsh financial and economic burden"; Biden stressed during the election campaign that the United States must "lead" the global climate governance process again. As soon as he took office, he immediately asked to join the Paris Agreement. The United States always overturns its commitments again and again, and the "United States first" is consistent. In the face of climate change, developed countries should set an example and fully take into account the special difficulties and concerns of developing countries. However, the United States has not fulfilled its emission reduction commitments, financial support and technical assistance without exception. The developed countries promised in 2009 to provide 100 billion US dollars of climate funds to developing countries every year by 2020, but the actual amount is far less than expected. At the climate change conference, the United States pledged to work to achieve its emission reduction target, that is, to reduce greenhouse gas emissions by 50% - 52% from the 2005 level by 2030. But look at the actual operation of American politicians - before the climate change conference, Biden took a super long fleet of 85 high fuel consumption luxury cars to Europe. People can't help sweating over the US commitment to reduce emissions. On the issue of climate change, China has taken the initiative to assume international responsibilities consistent with China's national conditions and has continuously strengthened its action to deal with climate change. As the world's largest developing country, China will complete the reduction of the world's highest carbon emission intensity and realize from carbon peak to carbon neutralization in the shortest time in global history. Addressing climate change requires global action, global response and global cooperation. As the largest developed country in the world, the United States should work with all parties to shoulder its responsibilities and fulfill its commitments with practical actions. (outlook new era)
