Steven Chu urges China to take the lead in setting 2050 emission targets

Steven Chu gave a very professional speech at Tsinghua yesterday. "If developing countries do not make commitments to reduce greenhouse gas emissions by 2050, the world will face serious problems."　　"U.S. Energy Secretary Steven Chu, speaking at Tsinghua University yesterday morning in a speech entitled" Tackling the challenges of climate change ", called on developing countries, led by China, to work with developed countries to make corresponding long-term emission reduction commitments. Chu's speech also showed that he was not only a political official, but a scientist, a Nobel laureate from an academic family.　　11 o'clock in the morning, 500 people can accommodate the main building of Tsinghua University, the report hall has been packed, Chinese scientists Yang Ning Yang and Mrs. Hongfan also attended the scene. Chu's first words succeeded in closing the gap between himself and Tsinghua: "I am very proud that my parents have graduated from this university!"　　Chu's father, Zhu Ruching, and his mother, Li Jingzhen, graduated from Tsinghua University in the early years and then studied at MIT in the United States.

From the Ice age temperature changes, to sea level rise, water tension, changes in arable land, and then to energy-saving refrigerators, energy-efficient batteries, energy-saving buildings, and so on, each section is supplemented with PPT demonstrations and detailed scientific data to support.　　But in the process, he rarely used gestures and body language, and occasionally a small gesture will attract a flash. In his speech, Chu also pointed out that China and the United States carbon dioxide emissions accounted for 42% of the world's total.　　He said that according to the IPCC forecasts, if the world's current industrialization continues, the global temperature rise of 5 degrees Celsius probability of up to 30%, "but the good news is that we can stop this trend."
