Major federal climate report rebuts everything Trump administration has said about climate change


Recommended Posts


 

Global warming is real. It's happening because of human activities, and it's on the cusp of pushing the climate toward tipping points or other "unforeseen consequences" that could reshape the planet as we know it, warns a new federal report released on Friday. 

The report, part of the Fourth National Climate Assessment, is mandated by Congress and has undergone extensive peer review by the National Academy of Sciences, various federal agencies, and the public. It's the most up-to-date climate science report since the U.N. Intergovernmental Panel on Climate Change's last report was issued in 2013, and it paints an increasingly dire picture of where the planet — and the U.S. in particular, is headed.

 

According to the report, global annually averaged surface air temperatures have increased by about 1 degree Celsius, or 1.8 degrees Fahrenheit, during the past 115 years. "This period is now the warmest in the history of modern civilization," the report states.

The last three years alone have been the warmest years on record for the planet since record keeping began, and have featured "record-breaking, climate-related weather extremes," many of which cost billions of dollars.

Contrary to the waffling of Trump administration officials, who have sought to portray climate change as real but the cause of global warming as up for debate, the dozens of scientists who wrote this report found no ambiguity about causality. 

 

The report states (original emphasis included):

This contradicts the views espoused by President Donald Trump, his administrator of the Environmental Protection Agency, and heads of the Interior and Energy departments.

EPA administrator Scott Pruitt has said that it's not clear how much human activities, such as burning fossil fuels for energy, are causing climate change.

"I think that measuring with precision human activity on the climate is something very challenging to do and there's tremendous disagreement about the degree of impact, so no, I would not agree that it's a primary contributor to the global warming that we see," Pruitt said in an interview on CNBC, when asked whether it's proven that carbon dioxide was the main cause of global warming.

The report isn't exactly heartening

 

The new study includes updated estimates on sea level rise, and they're not comforting. The report finds that global average sea levels have risen by about 7 to 8 inches since 1900, but that about half that increase — 3 inches — has occurred just since 1993.

"Human-caused climate change has made a substantial contribution to this rise since 1900, contributing to a rate of rise that is greater than during any preceding century in at least 2,800 years," the report states. The relatively small increase in sea level has already resulted in a large increase of so-called "nuisance flooding" in more than a dozen Atlantic and Gulf Coast cities, including Norfolk, Virginia and Miami.

The report projects that future sea level rise will amount to "at least several inches in the next 15 years" and 1 to 4 feet by 2100. The report's authors caution that an increase of as high as 8 feet by the year 2100 "cannot be ruled out," particularly if the Greenland and Antarctic ice sheets prove more sensitive to global warming than currently expected.

 

Compared to the previous National Climate Assessment, which was issued in 2014, this report contains more details on how extreme weather and climate events are changing nationwide. In general, it found that heavy rainfall is "increasing in intensity and frequency" across the U.S., though the increases are highest in the Northeast.

Heatwaves have also become more frequent since the 1960s, which is consistent with expectations from a warming climate, the report found.

According to the report, between 2021 and 2050, annual average temperatures in the U.S. are expected to rise by about 2.5 degrees Fahrenheit, relative to the period from 1976 to 2005.

The report contains new warnings that the course of climate change beyond the year 2100 will depend on choices made in the next decade or two since the magnitude of climate change will depend on the amount of carbon dioxide and other greenhouse gases emitted.

 

It's possible that if the world does not rein in greenhouse gas emissions, there could be as much as 5 degrees Celsius, or about 9 degrees Fahrenheit, of warming by the end of this century. Already, the amount of carbon dioxide in the air has passed 400 parts per million, which last occurred about 3 million years ago, at a time when sea levels and air temperatures were far higher than today.

 

"Continued growth in CO2 emissions over this century and beyond would lead to an atmospheric concentration not experienced in tens to hundreds of millions of years," the report warns.

"There is broad consensus that the further and the faster the Earth system is pushed towards warming, the greater the risk of unanticipated changes and impacts, some of which are potentially large and irreversible."

Examples of such unforeseen changes include a shutting down or dramatic slowing of the Atlantic Meridional Overturning Circulation, of which the Gulf Stream is a part, as well as the loss of huge portions of the Antarctic and Greenland Ice Sheets.

Sorry.  No. 

 

If Goebbel warming is real, why are ocean levels dropping, and why are ocean temperatures dropping?

 

so...now you claim that the clown's administration is all wrong about this as well????

"It is "extremely likely" that human activities are the "dominant cause" of global warming, according to the most comprehensive study ever of climate science by U.S. government researchers.

 

The climate report, obtained by NPR, notes that the past 115 years are "the warmest in the history of modern civilization." The global average temperature has increased by about 1.8 degrees Fahrenheit over that period. Greenhouse gases from industry and agriculture are by far the biggest contributor to warming.

The findings contradict statements by President Trump and many of his Cabinet members, who have openly questioned the role humans play in changing the climate.

 

"I believe that measuring with precision human activity on the climate is something very challenging to do," EPA Administrator Scott Pruitt said in an interview earlier this year. "There's tremendous disagreement about the degree of impact."  896.gif

 

That is not consistent with the conclusions of the 600-plus-page Climate Science Special Report, which is part of an even larger scientific review known as the fourth National Climate Assessment. The NCA4, as it's known, is the nation's most authoritative assessment of climate science. The report's authors include experts from leading scientific agencies, including the National Oceanic and Atmospheric Administration, NASA and the Department of Energy, as well as academic scientists."

GoofyShit has been on Facebook again....or watching Foxaganda for Idiots

Benson says NASA is lying.

 

On a NASA page intended to spread climate alarmism (https://climate.nasa.gov/vital-signs/sea-level/), NASA’s own data reveal that worldwide ocean levels have been falling for nearly two years, dropping from a variation of roughly 87.5mm to below 85mm.

If the sun shines on the ocean, water evaporates and goes up into the atmosphere.  And then, the humidity around the world rises, and we get more precipitation - like Houston experienced.... your line is a wiggly one as one would expect. The water that falls as precipitation in Iowa, for example, goes into the water table.  It doesn't immediately replenish the oceans.  If the sun shines on icepacks, they melt and cool the water around them, like ice cubes cool my tequila.  You approach global warming as if it were a simple arithmatic zero-sum game when it really is a complex calculus.

This following chart alone proves that nothing but a LIE ...

Sea-level-data-since-1855.jpg

 

As you can see, the slope of the line hasn't changed in a 160 years ... back to before the industrial revolution began pumping CO2 into the atmosphere.

That's because the CO2 meme of these AGWalarmists is a LIE.

And gosh ... given that sea level has been rising an average of 0.75 inches a decade, predicting several inches in the next 15 years doesn't seem extraordinary.

And maybe even hard to achieve since, as Golfboy showed, satellite measured sea levels have leveled off the past 2 years.

And let's see, it's 83 years till 2100, so 0.75 * 8 = 6 inches.   



I think predicting a 5 foot rise by 2100 is nothing but scare tactics with absolutely no basis.

 

The same tactics that AGWalarmists have been doing for 30 years.


HOW STUPID ARE THESE AGWALARMISTS?

PRETTY STUPID.
