White House OKs report warning climate change caused by humans

The smog-shrouded Los Angeles skyline is seen in this file photo from May 31, 2015. The latest US report says this current period in time is "the warmest in the history of modern civilization"

The US government released Friday a major scientific report that says climate change is "extremely likely" to be caused by human activity and will get worse without major cuts to carbon emissions.

The findings of the federally mandated report were approved by the White House, even though they are starkly at odds with the position of President Donald Trump, who has labeled a Chinese hoax and named fossil fuel ally Scott Pruitt to head the Environmental Protection Agency.

The Climate Science Special Report spans more than 600 pages and is part of a larger report known as the Fourth National Climate Assessment, which is being issued in draft form for public comment.

Based on "a large body of scientific, peer-reviewed research," global annually averaged surface air temperature has increased by about 1.8 Fahrenheit (1.0 Celsius) over the last 115 years (1901–2016), it says.

"This period is now the warmest in the history of modern civilization," said the report, available at science2017.globalchange.gov.

Since the last report of its kind was issued in 2014, "stronger evidence has emerged for continuing, rapid, human-caused warming of the global atmosphere and ocean," the text said.

"It is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century has been the dominant cause of the observed warming since the mid-20th century," the report added, noting there "is no convincing alternative explanation."

It was compiled by the National Oceanographic and Atmospheric Administration, with contributions from NASA, the Department of Energy and other federal agencies. Co-authors included more than 50 scientists from government agencies, universities and the private sector.

"I am quite confident to say that there has been no political interference in the scientific messages from this report," co-lead author David Fahey, director of the chemical sciences division at NOAA, told reporters on a conference call.

"I think whatever fears we had were not realized," he added.

"The word interference might have been a threat, but it never materialized. This report says what the scientists wanted to say."

Worse effects ahead

After examining long-term records and data going back thousands of years, the report said that in the modern era, "average temperatures in recent decades over much of the world have been much higher, and have risen faster during this time period than at any time in the past 1,700 years or more."

By the end of the century, "without major reductions in emissions, the increase in annual average global temperature relative to preindustrial times could reach 9 Fahrenheit (5 Celsius) or more," it said.

Sea level can be expected to rise "several inches in the next 15 years," and one to four feet (30 to 120 centimeters) by century's end, it said.

A global "rise of as much as eight feet by 2100 cannot be ruled out."

And Americans are already experiencing the effects of through heavier rainfall, coastal flooding, drought, more frequent heatwaves and wildfires, and earlier snow melt.

'Not new'

The findings came as no surprise to climate scientists.

"This isn't new," said Peter Gleick, president-emeritus of the Pacific Institute and a member of the US National Academies of Science.

"This is news only because Trump couldn't censor it," he said on Twitter.

The Trump administration has repeatedly denied or downplayed the role of fossil fuels in global warming.

EPA chief Pruitt shocked scientists earlier this year when he argued in a media interview that carbon dioxide was not a primary contributor to global warming.

However, the White House cleared the report for release, NOAA said.

NOAA said the report "serves as the foundation for efforts to assess climate-related risks and inform decision-making about responses."

The findings do not contain policy recommendations, but serve to inform future strategies.

The Union of Concerned Scientists senior climate scientist, Rachel Licker, said "the American public must hold legislators and policy-makers accountable for taking action commensurate with the problem."

Democratic Senator Al Franken of Minnesota and eight of his colleagues this week sent a letter to Trump asking "what safeguards are in place to ensure that the National Climate Assessment and the Climate Science Special Report give fair and accurate summations of the latest climate science without political interference."

The senators also asked how the Trump Administration plans to address the 's findings.

Amazing, the man who hires a mouthpiece simply because she is the daughter of one of his patrones, former Gov Huckabee of AR, now approves global warming is fact simply because he did not censor the report. It should be noted that Sarah Huckabee Sanders refused to condemn slavery when asked at a news conference. Heckufalotof Cornfedderate statues in the old Confederacy state of Arkansas. Should also be noted that it took 5000 army troops in to put down a rebellion in that state by the Ku Klux Klan after the War Between the States, as reported by the 7 volume Congressional Investigation of the Ku Klux Klan Report published in 1867. Evidently that state is full of those who would like to go back to the 'Jim Crow' era of slavery of man by man.... based on the color that WE ALL were 10,000 years ago. We all left Africa, the ancient origin or all our species, as people of color, for dark brown conferred resistance to sun damage to our skin.

Osiris1, modern humans left Africa more than 10000 years ago, and there were changes well before that. I'm not saying your general point is wrong, but we weren't all dark Africans at that time, otherwise you wouldn't have the indigenous people of the western hemisphere looking like they do, or the Chinese, for that matter.

I mean if Trump tweeted it then it must be true!

-as if people in Africa were ever one people.

Like everywhere else, Africa was a hotbed of overgrowth-driven intertribal conflict. Every once in a while a single tribe or alliance would gain a tactical or technological advantage and sweep a region clean, setting the stage for yet another round.

Waves of refugees fled north and east to escape the violence.

One of the more recent examples of this process was the genocide against the khoisan by the bantu.

And let us never forget the 1994 Rwandan genocide of Hutu against Tutsi who are basically genetically identical.

So please, don't perpetuate stereotypes and lies meant to divide and inflame. Emphasize similarities not differences and perhaps one day tribal animosity inherent in all of us will end.

And fight against the religions which use tribalism to divide and inflame while at the same time fueling overgrowth by encouraging reproduction and forbidding contraception in order to grow the flock.

One has to wonder what the political or financial pressure was here that prevented the regime from delaying denying obfuscating and lying like they usually do. If we knew it might turn out to be valuable later for getting more reality past these finks.

I'm guessing what you meant to say was that the administration had no confidence in previous studies because most were obviously politically-motivated hogwash, and waited until it could do a study that it could trust.

I'm sure you can understand that if the left didnt waste so much time and money publishing such rubbish, people might actually believe them.

Yes? Non?

I'd love for someone to explain how this bizarre comment is not off topic

You know this report is the same as all the others, right? This is science, the others were science, it's all science. It's done by the same people and comes to the same conclusions. It's the same. Suddenly you agree with it because Trump is president? And you accuse this mythical "left" of bias?

The same... as in the same researchers, the same data, the same methodology, the same peer review, the same publisher, the same funding, the same etcetc?

No I doubt it is the same.

You mean the way you disagree with the admins need for another study that it could trust?

Like that way?
And you accuse this mythical "left" of bias?
Absolutely i do. Youre incredibly naive if you dont.

""I am quite confident to say that there has been no political interference in the scientific messages from this report," co-lead author David Fahey"

-You're not appreciating that the pres (whom CNN calls 'Mr trump') APPROVED this AGW report despite the general conservative consensus.

You dont appreciate how indicative this is of his ability to be honest and non-political. As he usually is despite what the mythical left will tell you, and you mindlessly accept.

Nov 06, 2017
There's no particular obligation to consider Trump an honest man simply because people who work with him have, after long denying it, concluded that the sun does indeed shine.

And theres no reason to conclude hes dishonest simply because people who worked with hillary paid the russians millions to concoct a fake dossier.

Among SO many other lies.

No, it's the same. This is a NOAA report from NOAA researchers with the same conclusions that NOAA makes. It's the same. I imagine that with the problems Trump is having with NASA at the moment his staff have simply decided to pick their battles. Harassing individual scientists is easier than suppressing a major report from NOAA, especially when they're destroying NASA's satellite capability right now. NOAA may simply be benefiting from timing.

It's definitely not the same.

"Since the last report of its kind was issued in 2014, "stronger evidence has emerged for continuing, rapid, human-caused warming of the global atmosphere and ocean," the text said."

- And it's certainly not just NOAA;

"contributions from NASA, the Department of Energy and other federal agencies. Co-authors included more than 50 scientists from government agencies, universities and the private sector."

- And I guess you didn't even know this;

"Trump taps AccuWeather CEO to head NOAA..."

- So no, you only think you know what youre talking about.

Not really the same as knowing is it?

But you guys seem to think it is.

Why is that I wonder? It's just easier perhaps? Less painful? Harder to actually find out the facts than to make them up?

It's a mystery that's for sure.

Literally no clue what you're smoking at this stage

-maybe because you're too stoned to understand the content? That's my guess.

Let's dumb it down... leetard says
This is a NOAA report from NOAA researchers with the same conclusions that NOAA makes.
-so otto showed him that This is NOAA report with new leadership from not just NOAA researchers with much more trustworthy conclusions that NOAA makes using more accurate data from apolitical researchers.

Duh?

Yes you're right, dear. This pro-AGW report that no doubt started being compiled long before Trump was even elected is completely and utterly different from all the other NOAA reports that are pro-AGW and were compiled before Trump was elected.

The election of Trump has miraculously made climate science betterer, even though it's been coming to the same conclusions for the last 30 years. It's a neocon miracle.

Sorry sweetie you're still making things up

"Since NCA3, stronger evidence has emerged for continuing, rapid, human-caused warming of the global atmosphere and ocean. This report concludes that "it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."
even though it's been coming to the same conclusions for the last 30 years
Well according to this report 'it's' been guessing (and politically fomenting) for the last 30 years.

Under Trump we now have a report that's not just a lucky guess and a campaign ploy.
