“The Earth is experiencing the warmest period in the history of civilization and humans are the dominant cause of the temperature rise that has occurred since the start of the 20th century, according to an exhaustive scientific report unveiled Friday by 13 federal agencies. The report was approved by the White House, but it directly contradicts much of the Trump administration’s position on climate change.
“Over the past 115 years global average temperatures have increased 1.8 degrees Fahrenheit, leading to record-breaking weather events and temperature extremes. The global, long-term warming trend is “unambiguous,” the report says, and there is “no convincing alternative explanation” that anything other than humans — the cars we drive, the power plants we operate, the forests we destroy — are to blame.”
“…The climate science report is part of a congressionally mandated review conducted every four years known as the National Climate Assessment. The product of hundreds of experts and scientists within the government and academia and peer reviewed by the National Academy of Sciences, it is considered the United States’ most definitive statement on climate change science.”
