After the ice age....?

Question

Why did the earth warm up? The mammoths and such weren't driving hummers, but the earth warmed up anyway. Now, why is it "Global Climate Change" that is warming the earth? What if the climate is just changing as it has done in the past? Is there any TRUE evidence that the human race is to blame?

Answer 1

The amounts of CO2 we used ''tore a hole'' in the ozone layer, increasing the amount of UV. which is bad.

Answer 2

It's possible that part of the current rise in global temperature is due to natural causes. What is indisputable is that the rate of warming has not been seen in over two million years. In fact, it's orders of magnitude faster than any previous cycle measured.

Natural causes for cyclical changes can be simple, like a massive volcanic eruption, or more complex, like wobble in the earth's rotational axis.

No natural cause can account for the sudden and rapid changes now being observed. The reason scientists are sounding the alarm is because the evidence is overwhelming and they have been collecting and studying it for over thirty years. Only recently have non-scientists started paying attention.

Denying what is right in front of us is a recipe for the end of the human race. The earth will be here with or without us. Whether our children or grandchildren enjoy the same planet we have is our choice.

Answer 3

Over a period of the last million years there have been 4 Ice Ages, with the accompanying warm up.  So this is nothing new to the Earth.

There is NO evidence that the human race is to blame for this warming period.  What humans can take the blame for is pollution.  This human made pollution maybe having an accelerating effect on the natural event.  

There is plenty of hard evidence that many species of plants and animals, including humans, have survived all the Ice Ages and associated warm periods.  The polar bear is thought to have reached it's evolutionary climax about 500,000 years age.  That means it has survived two Ice Ages.  The gray squirrel has evolved in North America over a period of 37 million years.  It has survive much more than the polar bear.  Yet they're here, alive and well, and apparently happy with us humans.

If at all possible, ignore what you see in the media and from politicians, including Al Gore.  Try to find facts.  Check out this site.

Answer 4

It's "Global Warming" because it is convenient for certain people -- an easy way to get "browny points" for their agenda & justify social changes they want to see. Btw, the same people who now scream "global warming" 30 years ago predicted second Ice Age around the corner.

Yes, Earth's climate had been cyclic for millenia. Humans can not change it even if we wanted to -- Earth is simply too big. The eruprion of Mt. Helen back in 80's had produced more pollution than all automobiles combined, and I mean since the invention of the auto.

Answer 5

look up milankovitch-croll theory - the earth had always gone through periods of warming and cooling.  I'm convinced the governments have jumped on this band wagon because it's another way to tax us!  Humans have only been on this planet for a mere f**t with respect to the geological timescale.  I doubt we're as much to blame as it has been touted.  Makes good headlines and film subjects though!  Particulates in the atmosphere do affect Raleigh Scatter, clearing forests does affect the Earth's albedo, as will a reduction in ice sheet cover etc etc.  But I doubt all our heroic efforts won't halt what's coming naturally anyway, even if a teensy tiny bit of is our fault.

Answer 6

The climate modellers claim that only changing CO2 contents can explain the recent warming that the earth has seen.  That is, they have concluded that CO2 content is the primary driving force for recent warming.

As far as I can dig out of this whole mess, that is the primary and really only compelling evidence that man is responsible for recent warming.

Personally, I find the argument to be pretty weak for a number of reasons which I won't go into here.

I am pretty well convinced that most of the climate change, at least, is a natural phenomenon and thus throwing money at the "problem" in order to "fix" it is a complete waste of time and effort, taking away from a lot of very beneficial actions humans can take to improve conditions on the planet that are peripheral to the climate issue.

I even question the definition of the change as bad, as a negative thing.  It is just different..
