While Trump Bans “Climate Change”, Scientists Leak Science Update

August 9, 2017

Colbert on how climate change is helping build soil in his pants.


WASHINGTON — The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration.

The draft report by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited.

“Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” a draft of the report states. It was uploaded to a nonprofit internet digital library in January but received little attention until it was published by The New York Times.

The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change,” they wrote.

One government scientist who worked on the report, Katharine Hayhoe, a professor of political science at Texas Tech University, called the conclusions among “the most comprehensive climate science reports” to be published. Another scientist involved in the process, who spoke to The New York Times on the condition of anonymity, said he and others were concerned that it would be suppressed.

The White House and the Environmental Protection Agency did not immediately return calls or respond to emails requesting comment on Monday night.

The report concludes that even if humans immediately stopped emitting greenhouse gases into the atmosphere, the world would still feel at least an additional 0.50 degrees Fahrenheit (0.30 degrees Celsius) of warming over this century compared with today. The projected actual rise, scientists say, will be as much as 2 degrees Celsius.

A small difference in global temperatures can make a big difference in the climate: The difference between a rise in global temperatures of 1.5 degrees Celsius and one of 2 degrees Celsius, for example, could mean longer heat waves, more intense rainstorms and the faster disintegration of coral reefs.

Among the more significant of the study’s findings is that it is possible to attribute some extreme weather to climate change. The field known as “attribution science” has advanced rapidly in response to increasing risks from climate change.

Washington Post:

OVER THE next week or so, the Trump administration must decide whether to approve or suppress a major federal climate change report. Though scientists have signed off on its findings, including that the average U.S. temperature has spiked in the past several decades and that humans have almost certainly played a predominant role, President Trump and Environmental Protection Agency Administrator Scott Pruitt have indicated they simply do not believe the experts.

Even as the federal climate assessment has been under review, the warnings have grown starker.

A paper published last week in Nature Climate Change offered a harrowing view. International negotiators committed in Paris to keeping global temperature rise below 2 degrees Celsius, the point past which experts warn warming could be very dangerous. Analysts from the University of Washington and the University of California at Santa Barbara found that there is only a 5 percent chance the world will achieve that goal.

Instead of predicting how technology or policy might change, the researchers looked at how nations have done until now and inferred from those trends what will happen in the future. As economies expand, they emit more planet-warming carbon dioxide into the air. Fortunately, over time economies also produce more efficiently, using less fuel and therefore emitting less carbon dioxide for every widget assembled or mile driven. By projecting population growth, economic expansion and carbon efficiency into the future, the analysts came up with a rough guide to where the global temperature will be at the end of the century.

They found that there is a 90 percent chance the world will warm between 2 degrees and 4.9 degrees Celsius, with a median of 3.2 degrees. Though this avoids the most alarming scenarios scientists have previously considered, it also excludes the least concerning, finding virtually no chance the Earth will keep warming below the desirable level of 1.5 degrees Celsius.

Times again:

The E.P.A. is one of 13 agencies that must approve the report by Aug. 18. The agency’s administrator, Scott Pruitt, has said he does not believe that carbon dioxide is a primary contributor to global warming.

    Next we need the Trump administration to ban the words ‘national debt’. This seems a powerful way to make unpleasant realities go away. MAGA!!

    • dumboldguy Says:

      MAGA indeed!! The Trumpty-Dumptys are banning all sorts of truths as they deny unpleasant realities and substitute alternate facts in their place—-speaking of the national debt, it’s going to go DOWN when Trump cuts taxes on the rich—-believe him!

      And if they should be foolish to suppress the already-leaked report, the furor that will result may actually give the report more widespread publicity than it otherwise might have gotten.

      In the meantime, the planet dies the death of a thousand cuts.

        “speaking of the national debt, it’s going to go DOWN when Trump cuts taxes… believe him!” I believe, brother!! It was a simple accounting error when it doubled after Reagan cut taxes, and doubled again after Bush Jr cut taxes. Can we have some FAITH… I say… can we have some FAITH in Trickle-down economics???!!! GLORY Hallelujah, I FEEL the Lord in the belly of my soul!!!

          Don’t forget. It also doubled under Obama. The problem doesn’t lie in the White House. It’s in Congress where the money is actually spent.

          Congress is where the overhaul needs to take place. We need to vote in more independents and third-party candidates provided they are qualified to do the job.

    But, doncha just know it, the leaked report is fake. Prove it isn’t 🙂

    Welcome to ‘1984, The Reality Show: That Was Then This is Now’. All the poor suckers that were conned into voting for Trump are now going to be worse off as Trump only cares about lining the pockets of his rich cronies at the *expense* of the poor and the squeezed middle.

    Just hope the Mueller grand jury finds out sooner rather than later who in the Trump family owns all those Exxon shares, so that we can get this all over as quickly as possible.

    How could I forget the environment? I meant to say: “at the *expense* of the poor, the squeezed middle, and the environment.” Every single move the Trump administration makes seeks to roll back some important piece of environmental protection that was put in place over the past 100 years or so. It’s so blatantly transparent it’s beyond a joke.

    The report drafts have been public since january. The claim about leaked is a lie, repeated endlessly by the left.
