WASHINGTON: The US government is expected to release Friday a major scientific report that says climate change is real, caused by human activity, and is affecting the daily lives of Americans, reports AFP.
The federally mandated report, known as the Fourth National Climate Assessment, is issued every four years.
It is the first to come under the administration of President Donald Trump who has labeled global warming a Chinese hoax and named fossil fuel ally Scott Pruitt to head the Environmental Protection Agency.
“Average temperatures in recent decades over much of the world have been much higher, and have risen much faster during this time period, than at anytime in the past 1,700 years or more,” said a draft of the report, made public in August by the New York Times.
“It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century,” it added.
“Many lines of evidence demonstrate that human activities, especially emissions of greenhouse gases, are primarily responsible for recent observed climate change.”.
