Here's something to think about.
*3.5 billion yrs. ago - life on Earth
*545 million yrs. ago - Cambrian explosion of multi celled, hard-bodied organisms
*50,000 yrs. ago - mankind as we know it (post-Neanderthal, Cro-Magnon)
This means that if you shrunk down the history of life on Earth into one year, with the first single-celled organisms emerging on January 1 at midnight,
*The Cambrian explosion occurs at approximately 5:15 AM on November 6. Everything from New Year's past Halloween has been only celebrated by single-celled organisms.
*Mankind doesn't show up until about 11:53 PM on New Year's Eve.
What's even cooler? For the majority of the time when microbes ruled the Earth, they were actually synthesizing the oxygen we now breathe. Before photosynthesis, they used alternative methods in the nearly inhospitable conditions of infant Earth.

Yupp - and still we lament over small periods of our lives, focusing on the instant of clouded skies in an eternity of bright sunshine (just if you shrink your own life down to a day).
Enjoy your day, go outside and make someone smile - you can make the difference, every moment.
Thanks for sharing your moment, baby_bear

I like the one about showing a video in reverse at 24 frames per second where each frame is a year.
I forget the exact numbers and do not feel like working them out, but you would need to sit for about a minute to get to 0 AD/BC, about 20 to get to the start of men, about an hour for the dinosaur extinction and a few centuries for the Cambrian explosion. When I have had more sleep I will get more accurate numbers if someone else does not do so in the meantime.
Also assuming I remember.

The 6000th Anniversary of the Creation of the Earth (4004 B.C.-1996 A.D.)is about to be celebrated by Congregations that cherish the memory of the good and great Archbihop Ussher. This seems bound to spill over into their Congressional Districts, with obvious ramifications for the funding of Geophysical research.

There was an interesting paragraph in a book I read recently ("Chaos"), that gives significant pause for thought.
If you take the original point about the incredibly short period of time mankind has been on earth, it's very interesting to note the even shorter length of time the earth has had the current meterological climate for.
Going back over the history of the earth, it's swung from Ice age (even Snowball earth), to super-hot since the formation of the atmosphere.
Our current climate of temperate zones, small polar caps and air-streams has existed for a shorter amount of time than we have.
Many meteologists believe the current climate is a fluke transitional period and another ice-age is on the way.
All previous ice-ages have lasted millions of years... Our current climate is about ooooo 30,000 years old.

I know I know, it's not likely to threaten our generation, but there's a very good theory that global warming will actually lead to another ice age (I should really not post these things at work where I don't have access to any of the references)
But it did suggest that most of Europe could potentially be in permafrost climate within 400 years.
Theory as such:
Gulf stream moves further South (already happening)
Cooler climate means more snowfall further South, and less/no thawing of existing snow.
Increased snow/frost coverage reflects more heat so temperature cools even quicker
Process repeats as above and accelerates.
It's commonly known that neolithic european man were living in a harsh winter climate in the not-too-distant past (probably about the time William the Conqueror was battling wooliy mammoths ) - so it doesn't take a massive leap of faith to assume that the current climate isn't the norm, merely a anomoly. I
t's only due to our (humans) perception of time (to tie it back on to topic) that we've taken the current climate to be standard, when in fact it's practically a nano-second on the year-calendar of earth

From what I've read, they reckon a lot of areas will get hotter, but Europe, and a few other areas, will get colder.. I mean, England is just as far north as Moscow, it's just the gulf stream that keeps it (mostly) warmer, so if that moves..
Areas nearer the equator, also most of the Southern hemisphere, are likely to get hotter..
Possibly we should attempt the suggestion in a guy's magazine I read- a campaign in the UK to get everyone to drive up to the Scottish coast, fill up the car with rock and soil, and drive it down to the south coast, see how long it takes us to reach the Med..

Since the topic has shifted to climate change (or the more familiar misnomer, global warming), I think it only appropriate I go into this as well...
There are a few givens...facts, if you will:
*The average temperature of Earth is rising. In fact, it's accelerating.
*Massive release of carbon dioxide is contributing to (perhaps causing) this change
*The population of the species behind this emission (human beings) has doubled in the last 50 years
Now, scale Earth to a more managable size, say a glass sphere the size of a basketball. Provide the conditions (as we now perceive them) of temperature interaction...i.e. layer the poles of this sphere with something cold (say liquid nitrogen) and the "equator" with something hot (a contained hydrogen belt). While this model does not reproduce Earth's intricate balance, it resembles enough to make an argument.
Within this closed system (as Earth is), the thermal energy generated in the equator not only migrates, but pushes the colder enviornment in the poles to other regions. As we all know, molecules become more excited when more heat is introduced. These interactions can be thought of as currents. Warm air travels fast, and when it encounters cold air (which moves much slower, if at all), it pushes it along such currents. In a stable system, these interactions would remain somewhat constant.
Now, apply heat to the entire system. What becomes most noteworthy are these interactions. More heat means warm air becomes warmer, thus raising thermal energy and momentum. When this hot air hits cooler air, the force is much greater, propelling these cold currents more profoundly. Those regions subject to cold currents become even MORE susceptible, as cold air is pushed harder, faster, and stronger. In effect, moderate regions become much colder as hot regions become sweltering.
The point? AN OVERALL RAISE IN EARTH'S TEMPERATURE CREATES AREAS MUCH COLDER THAN WOULD BE OBSERVED OTHERWISE. On the surface, it seems counter intuitive, but the principles of physics speak otherwise.
