We have lived through 3 ice ages. So why are we so worried about a bit of global warming?

Answer 1

because people aren't really worried about the planet\

they're really worried about themselves

sure the planet can live through an ice age or three

but can all humans?

Answer 2

A bit of global warming ? Greenland is melting ! The last ice age was around 10,000 years ago .Did we survive that or did a small minority of us survive that ? We only have recorded (written history) dated back around 5000 years ago.Mayan, Chinese and Roman cilvisation were no more than 5000 years old.
Where would get your shopping done? Shops won't be opened because transportation by air or road is not possible.There will be food scarce because nothing can be grown in freezing temperature and the planet will be a white planet instead of a blue. The supply of energy would be jeopardised as all industry and transport is 6 foot under the snow...and so forth and so forth....

Answer 3

In fact global warming is happening faster than before.
I personally believe that on top of human activity also solar activity has a lot to do about it.
Also, I believe that we have the technology to correct the warming trend by screening part of the solar radiation with a cloud of orbiting reflective dust or reflective mylar foil.
Such screen should orbit over the equator at geastationary altitude, but turning the opposite way as the geostationary satellites. In such a way to remain always between the Earth and the Sun as the Earth turns.
We did that in our planet and it worked !

Answer 4

We have lived through ice ages before but what's happening now is on a much faster scale.

There are, for want of a better way of putting it, full ice ages and mini ice ages. The full ice age cycle takes approx 125 million years, during the approx 60 million years of warming the planet warms from it's natural minimum of approx 5°C to it's max of 35°C, over time it averages 1°C every 2 million years.

The mini ice ages aren't nearly as dramatic. These have a cycle of approx 100,000 years but in geological terms they end abruptly. The last one began ending 18,000 years ago and effectively ended 10,500 years ago. During this time the planet warmed by 7°C, roughly 1°C per 1000 years. The natural warming has continued since but at a much slower rate, namely 1°C in the next 10,000 years.

Compare these natural rates of change with what's happening now. At the present rate of warming it's taking just 56 years for the planet to warm by 1°C.

Answer 5

Human race, as we know it, only faced ONE major ice age, which ended around 10.000 years ago. Since then the climate on earth has been amazingly mild and constant - which probably helped in our "conquest of the earth".

If the scientific possible scenarios are correct... we should be veeeery worried. We are not ready for such a scale of change - specially with such an over-numbered population and so weaken ecosystems.The hard way we might understand how connected and dependent we all are from Nature and how crazy we were in not believing we could do such a difference and awake the "giant".

Answer 6

we are now only able to find that we have crossed 3 ice ages, before the ice age occurred the people were not so aware of it. but we today are very much aware, so we are worried too much. Also in those days, we lived with forest and animals, but today we are so much developed and civilized, which makes us to worry about it.
but as you said which is going to happen is going to, no can stop it.......

Answer 7

Because the rate of warming is so fast that neither mankind nor the natural world would be able to adapt to it quickly enough to avoid catastrophes.

If it goes ahead unchecked man would need to move many cities such as London to higher ground. We would also need to accommodate many millions of refugees from flooded countries and regions. At the same time huge new desert areas would be created with more refugees in consequence.

The natural world would also suffer many extinctions because animals and plants can only migrate slowly, particularly if cities and roads block the way. This would lead to a loss of biodiversity and an increased risk of catastrophic wildlife events.

In summary a bit of global warming caused by our greedy lifestyles could deliver serious environmental and economic damage to mankind and the natural world. We need to wise up quickly.

Answer 8

think about this
those ice ages ended with what.
global warming.

the treehuggers try to make it sound like earth has never before had global warming.

or that global warming is dangerous.

or that it will end life on earth.

Answer 9

The effect of Ice age on the environment are very mild compared to a hot age.
ice ages occur every 20000 years or so, and the effect is cold but mild weather, less precipitation, they also occur very gradually.
Hot ages are much rarer, millions of years in between, and the climate becomes wilder during such ages.
also so mass extinctions occurred during hot ages, but not during ice ages.

Answer 10

Because we Americans are fat, And I don't want to see a bunch of guys in speedos walking around in my streets. Yes it would be nice if there were some hot chick waling around in bere minimum, but frankly Jessica Alba types are rare and we have to see 100's of people over 300lbs before we find teh one with a nice bod.
