Warmair, the opening words of the document to which you supplied the link are:

“Emissions of carbon dioxide from the burning of fossil fuels have ushered
in a new epoch during which human activities will largely determine the
evolution of the Earth’s climate.”

This is a baseless statement. There is no science which demonstrates any measurable effect of human emissions on climate.

Please desist from inflicting fraudulent rubbish like this on us.

ant, if the NCA is based on false temp records, which is plain, because the adjustments create the trend then any conclusion about AGW flowing from that is equally false.

Another fraud-backing document was noted by ant this week, the NCA release. She mistakes it for a scientific document.
“The National Climate Assessment is a political call to action document meant for the president’s left-leaning constituency. What pretense of scientific support that decorates it quickly falls away under a close and critical inspection.”
Obama lied about the science when he launched his initiative on “climate change” last year. This document backs him with its falsehoods. The letter submitting the report to Congress “concludes, “When President Obama launched his Climate Action Plan last year, he made clear that the essential information contained in this report would be used by the Executive Branch to underpin future policies and decisions to better understand and manage the risks of climate change.”

On 31 March there was a press release from the IPCC in relation to its release of a report on “climate change”. As expected, it is a fraudulent assertion of climate lies. It identifies eight “areas of concern”.
These have been reviewed by independent scientists and are shown to be nonsense,
For example:
IPCC: “Risk of loss of marine ecosystems and the services they provide for coastal livelihoods, especially for fishing communities in the tropics and the Arctic.”
Independent Science: “Rising temperatures and atmospheric CO2 levels do not pose a significant threat to aquatic life. Many aquatic species have shown considerable tolerance to temperatures and CO2 values predicted for the next few centuries, and many have demonstrated a likelihood of positive responses in empirical studies. Any projected adverse impacts of rising temperatures or declining seawater and freshwater pH levels (“acidification”) will be largely mitigated through phenotypic adaptation or evolution during the many decades to centuries it is expected to take for pH levels to fall.”

I am confident that if ant can discover anything about the actions of the fraud-backers which she thinks is not fraudulent, she will draw it to our attention.

On the endless topic of AGW fraud, Hansen, the Climate liar, and top NASA scientist said this in 1999:

in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country

Harmless enough, but true, so NASA(or Hansen) have had the presence of mind to remove it from their website

cohenite, what an inane comment..."ant, if the NCA is based on false temp records, which is plain, because the adjustments create the trend then any conclusion about AGW flowing from that is equally false."

It is very easy to claim the NSA is false in relation to temperature, but to debunk the Report you need to undermine the 3,000 plus references that support it.
To say it is false is meaningless without absolute evidence. You need to be able to debunk the subject areas of Forestry, Agriculture etc I have mentioned in another post. The NSA says that climate change has already impacted on the US

I'm aware that Watt's has suggested that temperature has been fraudulently processed. However, Watts's allegations have been investigated and found to be fallacious.

Climate change is happening in Alaska, the tundra is melting, the coastlines are not protected by ice and are eroding. Roads are slumping as are some foundations of houses also. For tundra and ice to melt I believe warmth is needed. cohenite, you clearly have another view on how melting can happen without the temperature increasing, can you please explain. It has been a trend for a number of decades.

The recent NSA Report also discusses glacier retreat in the USA, what might cause glacier retreat other than temperature going up. There are a few exceptions, once again can you indicate how most glaciers in the USA are retreating if temperature is not a factor.

cohenite, acidification has been identified as already happening, nothing academic about that.

Quote "...Kathleen Nisbet-Moncy, plant manager for Goose Point Oyster Co. in Willapa Bay, Washington, told ThinkProgress that ocean waters in the bay have become so acidic that the company can’t grow oyster larvae off the coast of Washington anymore. The problems started happening in 2006, she said, when winds that cause upwelling off the West Coast didn’t subside as much as they usually do."
