The 299-report, published by the Bulletin of the American Meteorological Society, relies on the work of hundreds of scientists in 60 countries.
Global sea level was also the highest on record, at 82 millimeters higher than the average in 1993, when records began to be recorded with the current method.
In leaking the report (obtained by The New York Times), scientists within the government ensured that their work would reach the public, serving as a check on the administration in case it did indeed try to trump science with politics. We should treat this document for what it is, an unfinished draft that requires serious revision.
But in a correction added later, the Times admitted that the report they were concerned was going to be suppressed had already been made publicly available.
Several real climate scientists contacted by Gizmodo felt Smith was not as up to snuff on his research as he claimed to be, however. This is not a scientific process - it's a political one. "It compels action to prevent climate change".
"It's a fraught situation", said Michael Oppenheimer, a professor of geoscience and global affairs at Princeton University who was not involved in the study.More news: Stocks fall on Trump's North Korea warning; dollar up after data
It notes, with "very high" confidence, that the severity and frequency of hot days has increased since the 1960s, while the number and severity of colder-than-average nights has fallen.
On global warming being a hoax invented by the Chinese, the previous National Climate Assessment, NASA, EPA, the National Academy of Sciences and many other scientific organizations say otherwise.
"It may be that we have to struggle with revenues, just as costs are increasing", Corbett said. The Times followed with publication of the final report.
A new government report warns that regions across the USA are feeling the effects of rapid climate change, with some of the greatest impacts in Alaska and the Arctic. Almost three-quarters of that human caused warming is from carbon dioxide, the Nobel Prize winning Intergovernmental Panel on Climate Change said, citing "very high" confidence levels.
Global annual average atmospheric Carbon dioxide concentration was 402.9 parts per million (ppm) which surpassed 400 ppm for the first time in the modern atmospheric measurement record and in ice core records dating back as far as 800,000 years, the NOAA said.
"The last few years have. seen record-breaking, climate-related, weather extremes, as well as the warmest years on record for the globe". "Yes, both were influenced by the big El Nino, but 2014 is the next warmest and it wasn't". Pruitt has said repeatedly that he does not believe human activity plays a large role in climate change. "Meanwhile stronger droughts (think California), and now year-round wild fire seasons, cause tremendous hardship and disruption and monetary losses. Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate changes". Smith is just one dude who won a few elections in Texas and has no formal scientific qualifications whatsoever, but who does take an bad lot of money from the oil and gas industry.
