Key to the latest Eddie-Snowden tidbit:

Even more troubling, according to Information’s assessment, is that the top secret “document suggests that the NSA’s […] focus in relation to climate change was spying on other countries to collect intelligence that would support American interests, rather than preventing future climate catastrophes.”

This newest sketch in the whacked NSA portfolio was the snooping/spying the agency performed on behalf of the US before and during the 2009 UN climate summit in Copenhagen, Denmark, a supposedly big-deal event following the landmark 1997 Kyoto Protocol, and was to take near-drastic steps to cut gas emissions.
The meeting was a bust, ending with crapped-out acrimony and bullshit.
Also well-involved in Copenhagen was those nasty boys from the NSA.
From the Danish newspaper, Information:

The document, which Information has obtained via NSA whistleblower Edward Snowden, describes how, “analysts here at NSA, as well as our second party partners, will continue to provide policymakers with unique, timely, and valuable insights into key countries’ preparations and goals for the conference, as well as the deliberations within countries on climate change policies and negotiation strategies.”
…
The NSA deals with signals intelligence activities, and proponents of the agency’s methods usually focus on its role in the war on terror.
However, the leaked document illustrates that the NSA and its second party partners, i.e. intelligence agencies from Great Britain, Canada, Australian and New Zealand, also played a central role in promoting American strategic interests.
…
The leaked document states that “leaders and negotiating teams from around the world will undoubtedly be engaging in intense last-minute policy formulating; at the same time, they will be holding sidebar discussions with their counterparts – details of which are of great interest to our policymakers.”
And it adds: “Signals intelligence will undoubtedly play a significant role in keeping our negotiators as well informed as possible throughout the 2-week event.”
‘Sidebar discussions’ refer to informal and ongoing discussions between delegations from the different countries which took place in pre-booked conference rooms, in hallways, and in common areas at the conference center. According to the document, the information collected by NSA would be used to brief American politicians, notably including President Barack Obama and then Secretary of State Hillary Clinton, both of whom attended the 2009 summit.
…
And several sources from the Danish delegation have told Information that maintaining confidentiality during the negotiations was difficult.
“Both the Americans and the Chinese were always peculiarly well-informed. Particularly the Americans. I was often completely taken aback by what they knew,” says an official from the COP15 office.

The NSA saga is indeed a fascinating piece of shit.
And as most-likely the greatest threat to humanity is surging right at us, these clowns are playing cat-and-mouse.

National Intelligence honcho Jimmy Clapper: “Increasingly the environment is becoming an adversary for us. And I believe that the capabilities and assets of the Intelligence Community are going to be brought to bear increasingly in assessing the environment as an adversary.”

Lunacy.
