Who is denying global warming?

Recently, the "New York Times" published an article entitled "This is not what you imagine: the summer is getting hot" article. NASA retired climate scientist, Columbia University professor James Hansen (James Hansen) of a study shows that since the 1950s, the summer temperature gradually tend to be extremely hot.

Hansen and his two colleagues obtained a fixed baseline mean by comparing the actual summer temperatures for each decade since the 1980s. On the basis of this, from 1951 to 1980, one-third of the summer in the northern hemisphere was considered "normal", one third was "cold" and one third was "hot". After 1980, summer temperatures drastically changed, between 2005 and 2015, two-thirds of the year fell into "hot", and 15% went into a new district: "extremely hot".

Nevertheless, global warming is still a controversial topic. Last week, Project Syndicate released the article "Uncovering the Mask for Closer of Climate Change", author Benjamin Franta, a former researcher at the Harvard Institute of Science and International Affairs at Kennedy College, Harvard University, currently at Stanford University A Ph.D. degree in scientific history, dedicated to environmental policy and scientific manipulation of the study. He pointed out that 25 years after the United Nations Framework Convention on Climate Change in 1992, the world still did not establish an agreement to deal effectively with global warming, and President Trump also allowed the United States to withdraw from the Paris Agreement, Causing the power of procrastination.
