"Obviously President Trump and those in his administration didn't want this information out, but somebody somewhere said, 'You know what?"
The average surface temperature of Earth has gone up about 1.1 degrees Celsius since the late 19th century.
In particular, "the 3.5 ± 0.1 ppm [parts per million] rise in global annual mean carbon dioxide from 2015 to 2016 was the largest annual increase ever observed in the 58-year measurement record". "There are no alternative explanations". Though scientists have signed off on its findings, including that the average US temperature has spiked in the past several decades and that humans have nearly certainly played a predominant role, President Trump and Environmental Protection Agency Administrator Scott Pruitt have indicated they simply do not believe the experts.
But it's not a gauntlet laid down by outside scientists or activists.
And while it was prepared largely under the Obama administration, it's not a political document. This month, he formally notified the United Nations that the USA will withdraw from the Paris climate agreement, reneging on the nation's commitment to reducing heat-trapping pollutants. During his election campaign, Trump called global warming "a hoax" and promised to scrap the agreement.
One of the surest signals that local governments are taking climate change seriously is that they're looking for new ways to pay for it.
Scientists familiar with both drafts said there was no substantive difference between them.
A report by the American research center comes on the backdrop of the US decision to withdraw from the Paris climate agreement, as urged by President Donald trump.
Turns out, the draft report has been publicly available for seven months, meaning the Times "scoop" was no scoop at all.
In other words, it has passed all the usual tests for scientific integrity. Rather said during an interview with MSNBC's Chris Hayes.
If Trump decides he can't stomach approving the report in its current form, he'll have to remove or alter the parts he finds objectionable. They can approve it either as it is now written or with changes from the political team in the White House.
If that happens, she said, "the author team will then have to decide whether they can make [those changes] or not".
Many climatologists are concerned that the Trump White House could hide the report or alter its findings.
Richard Alley, another Penn State geosciences professor and expert on the Earth's cryosphere, noted Smith was correct the report was a draft finished some time ago, so it could not include "the absolutely most recent data".
This is stated in the report of the National administration oceanic and atmospheric administration (NOAA) of the United States.
- Global sea level rose another quarter of an inch (3.4 millimeters) for the sixth straight year of record high sea levels. The amount of additional warming coming from human activity - mostly burning of coal, oil and gas - is more than 40 times stronger than changes in the sun's heat.
Less than a week from this announcement, his government's chief science agency released a report expressing the global warming was real and getting worse every day.
Combining historical temperature data and state-of-the-art climate model simulations, the new study finds the likelihood of experiencing consecutive record-breaking global temperatures from 2014 to 2016 without the effects of human-caused climate change is no greater than 0.03 percent and the likelihood of three consecutive record-breaking years happening any time since 2000 is no more than 0.7 percent.
Over the northern and eastern Indian peninsula, a week- long heat wave at the end of April saw temperatures exceed 44 Celsius, contributed to a water crisis for 330 million people and to 300 fatalities, the report said.
Ardnt explained that NOAA doesn't specify what warming is from climate change and what is from weather events.
