... I'll believe it when I read about it in a journal.
You definitely do not understand the scale and nature of the current predicament (or may be you just make it seem like that's the case on purpose, possibly with a noble intent), in my humble opinion.
Do you honestly believe some journal(s) will be allowed to write about ongoing large-scale geo-engineering effort in the Arctic (if or when such an effort begins)? Really? When Manhattan project revved up, how many papers on fission were published on US scientific journals, do you know that? I'll tell you: none. This _silence_ about fission was so loud that USSR not just realized "something's wrong" about it, - more, because of this silence, USSR started its own program in the field (Holloway 1994, pp. 76–79). You see, even papers (about fission and some related fields) which were made by scientists COMPLETELY not involved in, and unaware about, Manhattan project - were prevented from being published. Much like that, present-day in-the-field researchers in the Arctic are most likely "unable" to publish everything they'd like to publish themselves.
If there is geo-engineering in the Arctic - the political and economical consequences will definitely be comparable, and in the long-term, - most likely much more massive, than consequences of Manhattan project. What makes you think that powers that be will allow YOU to read all the proper details about it in a scientific journal (i.e. truth, and complete truth, - not some cover-up fake piece of BS, which nowadays they make to avoid this "silence is telling!" effect which resulted in the start of USSR nuclear program in 1942)?
We know how tight security was around Manhattan and some other top secret projects. Full scale, nature and importance of those are known only to few dozens people (at most) in the world (including those few who lead countries strong enough to spy-and-analyze into the truth), up and until such a project keeps its top secret status (i.e., until reasons to have it top secret - remain actual).
And would you kindly avoid calling me "paranoid" or otherwise hinting or pointing (erratically) to insignificance of state security and corresponding services. At least, without making sure you know the basics like

P.S. In the case of Manhattan project, thousands and thousands of people were working for years to produce nesessary matherials and equipment, but they had no idea what they actually create and what's the meaning of the project. Most didn't even know any "project" exists. They had big problems with workers' motivation because of that; for example, some 100+ sports teams were created (for workers to have some meaningful - for them, - way to pass some time, i.e. to play in such teams and/or get otherwise involved in those sport activities), to boost morale of Manhatten project workers. No doubt, modern ways to "keep in the dark" and to motivate personnel - are much more advanced.
