Very interesting paragraph and the rest of the article is as well. How long can we continue to ignore scientists warnings? Because they are becoming more severe.

In the 1970s, they predicted that the world's food supply would collapse if the world population got to 6 billion. We are at 6.8 billion, and the proportion of starving people in the world is lower than it was when the population was at 4 billion. Scientists are predictably bad at forecasting the future.

The mid 70's was also a period of some relativly cold winters. Climatic scientists were saying all the polution we were putting into the atmosphere was reflecting sunlight, and we were on our way to the next ice age.

Well, that is kind of what is going on now. When the ice sheets melt, all the freshwater being put into the ocean would not only raise the sea levels and create all those "lost cities of Atlantises" that I somewhat mentioned earlier, but it would slow down the transatlantic current even more than it already is (a lot slower than 50 years, possibly in a cycle) and then there wouldn't be any warm water flowing into northern Europe or Canada, creating somewhat of an ice age. Then, perhaps it is winter in the northern hemisphere, and a record cold winter. That would give time for the ice sheet to spread southward, and by springtime the sun wouldn't be enough to melt it as it would keep spreading. Then we'd have to wait another few million years till all the ice was gone.

The ice age cycle is in the tens of thousands of years, not millions.

I never said that ice ages only take thousands, I meant that if the whole entire Earth froze over it would take millions of years to get out.

1) The whole earth cannot freeze over. It never has, and never will.
2) Ice age cycles take in the 10s of thousands of years.

Actually... I recently watched a show on the discovery channel of a 50-year-old theory that the Earth once totally froze over. Over the 50s and 60s and 70s most scientists dismissed it as "laughable" but now there is significant evidence that the total Earth froze over 600 million years ago. So, in theory, you simply cannot say that the Earth will never freeze over.

The earth/sun system was different then. Basically, due to an increase in the sun's luminosity since then, most scientists think that outside of a large asteroid/comet impact, it is a very unlikely scenario.

Wouldn't it be interesting if the predicted Islamization of Europe happened, and they inherit a popsicle? A re-emergence of the Nordic superman coming in waves down from Scandanavia to vanquish the shivering Mohammedans.........that sounds like the beginnings of a fun novel.

Billions will be dead from old age by then.

I was going to say that...

Billions of dead by 2000..

Seriously, how long has the world been in existance?

Unless your stupid and think the world is a few thousand years old, ALOT.

Up till this point, it seems logical that at least a billion humans have died.

Will those of you who are predicting a enviromental catastrophe please come to a decision as to whether it will become much hotter or much colder. I want to know whether to buy more winter clothes or summer clothes.

Well, let's just hope their predictions of billions dead is about as accurate as their predictions for this year's hurricane season being worse than last year's. :lol:

That was my first thought exactly. I don't know the stats off the top of my head, but assuming that at least 50% of the world's population is above the age of 25, given life expectancies for that age group and above, at least 4-5 billion people will die between now and 2100.
