'World's loneliest tree' records new epoch

Most scientists would agree that the Earth has now emerged in to the Anthropocene era - a new geological period defined by mankind's influence over the planet's climate and environment.

Radioactivity in tree rings seems to be an arbitrary standard. 

The ancient Romans' worldwide copper smelting pollution is also evidence of "mankind's influence over the planet's climate and environment."

There is no way to measure the start of a geologic era when you're in it because there's no geological measurements at the top of the rock strata series to know when the global geology changed enough to justify a new geological timescale boundary.  And there's certainly none that has been found yet globally.  Using radiology from a tree that was local to a small regional environmental event (Atomic Bomb) caused by humans to justify a global geographical timeline division is very weak reasoning such that it hints an an ulterior motive.  Mankind could come and go into extinction and even that wouldn't justify a geological timeline boundary event using current technologies.  As far as I know mankind has not caused any global geological marker that can be measured all around the world that would justify such claims.

 

Ulterior motive?  They may just want to make the insinuation that mankind is having such a drastic effect on Earth that we must now classify it with the gravitas of a geological timescale division.  There's no geographic evidence for fear mongering at this scale.  It's just ridiculous, IMO.

Perhaps the funding was more available to "prove" man's eeevil use of "nucular" technology.

Anyway, I simply found just as valid of a historical standard to use in rebuttal. 

Guessing the scientists had fun on the trip..

The loneliest tree? Why didn't the son of b's that planted it plant others so it had company?

WTF?  We already knew when atomic bomb tests happened, and didn't need to test tree rings to find out.  And how did those bomb tests have any kind of significant "influence over the planet's climate and environment?"  Why not pick the natural selection of darker moths due to the industrial revolution as the start?  Or the domestication of wolves?
