Before being elected as president, Trump repeatedly denied the existence of global warming, while his opponents deemed his environmental policy as regressive. Moreover, the Guardian newspaper, which obtained White House emails, reported Monday that US officials have been instructed to completely avoid using the term "climate change."
"Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans … Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change," the New York Times reported Monday citing a copy of the drat report, which is part of the National Climate Assessment.
The report stressed that the last 15 years was the warmest period recorded on Earth, and that the global temperature continues to rise gradually, surpassing previous annual records every year.
"Global annual average temperature, measured over both land and ocean, has increased by more than 1,6 F (0,9 C) from 1880 to 2015 (very high confidence). Long-term climate records indicate that average temperature in recent decades over much of the world have been much higher than at any time in the at least past 1700 years," the report read.
According to the newspaper, the scientists who prepared the draft are afraid that the White House will not allow an official release of the report, since it contradicts the administration’s general environmental policy.
On Friday, the United States submitted its formal communication indicating it will withdraw from the Paris Climate deal as soon as possible.
The Paris climate agreement was adopted within the United Nations Framework Convention on Climate Change in December 2015 and came into force in November 2016. The accord has been signed by more than 190 countries and ratified by 159. As stipulated in the document, all parties should maintain the increase in average global temperature at below 2 degrees Celsius above pre-industrial levels by reducing greenhouse gas emissions.
