I Love 'Science'

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'eureka!' but 'that's funny...' - Isaac Asimov

A team of US researchers at Purdue University, Indiana have built a ping-pong gun that can fire balls at supersonic speeds of more than 400 meters per second or Mach 1.2. The gun fires a ping-pong ball faster than a supersonic F-16 jet.

And the gun they built is not some hell of a machine, its just beautiful science :-)

Freaking amazing!

Ofcourse, even though we are on a near ideal course, there are rogue nations, greedy nations, nations toppling legitimate democratic governments for access to minerals, etc. which continue to threaten the equilibrium. Nevertheless, if we look back there is relative peace after the invention of nuclear weapons than before them.

@Nicholas - Looks like we are going off topic here... A topic about international diplomacy would be right place to discuss our ideas about these issues...

Suggests that humans have entered and cause a new Epoch, characterized by the adverse effects Humans have had on our world.
Some Geologists are of the mind that this is nothing more than a pop culture phase, but is there more to it than that?
100 years from now would it have an effect if our future children read of the time of Humans when ignorance ran like water among our race at the beginning of the Anthropocene Epoch, where we caused mass extinctions of various species, polluted the oceans, changed the Global temperature, perhaps permanently? Would they find themselves thinking "what was wrong with these people?" as we so often find ourselves doing upon reflection of our ancestors?
There is debate as to when the Epoch would begin, would it be at the start of the Industrial Revolution? The 1800's was a critical time period for Humanity, both for technology and growth. However it is also known that our most volatile changes today in temperature and sea levels started way back when we first started burning fossil fuels.
Should we focus so much on the Anthropocene Era as the epoch of Ignorance? Why not change the focus instead to an Era of solutions?

fair enough. I started a post called climate theory. PLEASE feel free to "splice into it" at your will. It will be easier to build one cohesive, sequential discussion, than play chat in the comments.

we can list agreed facts, agreed theories, agreed points of contention and there likelihood, potential impact, and agreed margin of error range in our disjointed belief.

CO2 is a greenhouse gas. But it need not be the culprit every time. In the said graph CO2 lags for the same reason. Something else is driving the change and CO2 system on earth is playing its part. That again does not mean that CO2 cannot start the change. Its just that in the studied events CO2 did not lead the change.

Great! You started a Topic! :-) We can discuss each forcing individually, debate its workings and magnitude of influence on the climate of earth. Someday may be we will throw enough light on the issue that a learned opinion can be formed about it. :-)
