Do these event happens a lot ?
Historically...no. In the last 30 years? Yes.
Can it make the sea level go up ?
Not only CAN it....it MUST cause sea levels to rise.
Does 2012 have something to do with it ?
Only in the sense that in 2012 we continue to needlessly destroy our environment instead of shifting to renewable, clean energy production and
responsible designs for our buildings.
Do we have something to be worried about?
Yes. What's relevant is not so much that the climate is changing...but the SPEED at which the climate is changing. The shift is happening too
quickly for much of the world's fauna to evolve to handle their new environments.
If things progress as they have been for the last 30 years without MASSIVE game-changing innovations and/or changes to human behavior the global food
chain will collapse and the preponderance of the human race will die out.
That being said...we are a bit like cockroaches so I don't think we will go completely EXTINCT...it will just seem like we did when 7 billion people
become 1 billion or less in the span of a generation or two.
Unfortunately, history tells us that while the sheer arithmetic of caloric shortages would be devastating...our decline will almost assuredly be
accelerated by a sharp increase in the perpetual state of endemic warfare that mankind has existed in since the day we started practicing agriculture.
Our instinctive reaction when resources are constrained is to turn on one another and simply steal what the rival troop of hominids next door has on
Of course, we must take into account the complex society in which we live in. We won't CONSCIOUSLY go out and say to another country "Hey...we are
going to steal your food now". Instead, there will be all sorts of other "justifications" for this behavior, but most of them centering on
exploiting the base fears humans have of other hominids who ascribe to different political, religious, and economic ideologies. There is a good
chance that in our quest for caloric input might not be focused so much on the FOOD itself, but rather upon OTHER forms caloric energy which we could
use to produce more food. Oil, for example, can be used to run tractors, ship food around the world, and create OTHER products which produce revenue
which could then be traded for food.
Thus, during the early stages of food chain collapse, it is highly probable that even though the PRICES for food are escalating dramatically, humans
will likely exhibit a predisposition towards blaming/explaining this phenomena via other events which are themselves symptoms of fundamental problem
of having too many humans and not enough caloric input to sustain them.
For example, it's reasonable to think that humans might attribute these exponential increases to something like market instability, a vaguely defined
concept of "inflation" that fails to account for why FOOD is increasing in price more rapidly than pretty much anything else, or even attribute the
entire problem to a single scapegoat figurehead's policies in government somewhere because accepting the reality that lots and lots of people are
going to die horrible deaths unless we change RIGHT NOW is simply too frightening to fully contemplate.
This phenomena of refusing to accept the obvious facts in front of you because their implications are terrifying can also be seen in other areas as
well. For example, the evidence CLEARLY points to multiple gunmen and a coverup in the assassination of JFK...yet 40% of Americans refuse to accept
this possibility. Likewise, we have had astronauts, high-ranking military personnel, former intelligence agents, and heads of state ALL tell the
public in point-blank terms that ET life forms are visiting our planet...yet for some bizzarre reason people are still waiting for "disclosure" of
some kind as if it HASN'T ALREADY BEEN DISCLOSED TO US. How about RFK? The audio of the shooting CLEARLY demonstrates that more shots were fired
than could possibly be held in the gun that Sirhan Sirhan was allegedly using. There is no debate that there was a second gunman and THERE NEVER WAS.
It's not "new" evidence...it's been there all along. Yet still, nobody in the past or present has seemed particularly determined to find out who
that somebody was...because it implies that a highly organized, well trained, group of some sort has been covertly subverting the American government
for a LOOONG time.
And that's scary....so instead we just sort of dismiss/ignore the evidence right in front of our faces and tell ourselves that "it will be OK" even
though we all KNOW that it will NOT be "OK".
Perhaps our impending extinction is well deserved after all. Maybe we are just simply not fit enough to survive.
