The transition periods from one Geological Epoch to a new Geological Epoch are are relatively rare events separated by many millennium. The last time this kind of transition happened was at the end of the Ice Ages approximately 11,500 years ago that marked the beginning of the current Epoch the Holocene. The Holocene brought profound transition in the earth's climate that nurtured the rise of human civilizations.
Now the current Holocene Epoch is being brought to its conclusion by those same human civilizations that it gave rise to. Human civilization and its increasingly powerful the technologies have grown to become the most dominant force shaping the planet's climate. We are changing the Earth's Nitrogen cycle. We are changing the Earth's carbon cycle. Mankind is now conducting a vast experiment with our planet's atmosphere, its oceans, and its soils. The cumulative result of all these changes is we've moved our planet into an new Geological Epoch, the Anthropocene named for the human species who created it.
.
There is still some controversy over the Anthropocene Epoch with some Geologists arguing the evidence isn't there for it yet. But when human caused Climate Change will raise sea levels for the next thousand years and cause a number of drastic changes I don't think there's much doubt that we've entered a new Epoch of our own making.
How will billions of us fare in the new Anthropocene Epoch isn't certain but from what we can surmise the future Anthropocene Epoch doesn't look encouraging. We can even predict when your city is likely to depart from the familiar Holocene, and leave it behind.
I've chronicled many of the disturbing aspects of Climate Change for years.
From just the other day:
IPCC Report: Climate Change is very likely to create critical Food Shortages in this century
From several months ago:
M.I.T. Study: Climate Change will produce more frequent Hurricanes & more big Hurricanes
Increasing frequency of El Ninos may be linked to Climate Change
From earlier this year:
NOAA: 2012 had Second Largest Annual Increase in Greenhouse Gasses
From 2012:
New studies: Climate Change kills 400,000 a yr & costs $1.2 trillion or 1.6% of World's economy
New study links increased wildfires to Climate Change
New study in Nature links Climate Change to recent increase in extreme weather events
From 2011:
The Arctic has changed in last 5 yrs. to a "New Normal" with no way of going back
Study: Climate Change is driving more conflicts
From 2010:
Study: Climate Change may make half of Earth "uninhabitable environment" for humans
From 2007:
UN Report - Sea Levels To Rise For The Next 1,000 Years
