Has global warmin happened b4...if so y r we so worried..why did animals survive?

Question

If it did we would survive if other animals did......

Answer 1

we would survive but we're not like other animals though, we've become reliant on electricity, proper housing, etc. they wont survive and we really wouldn't like to go back a few centuries in terms of lifestyle.

Answer 2

Global warming periods have happened before to the best of our knowledge, as much as there are changes in seasona temperatures.

Answer 3

Previous global warming - many hundreds of thousands of year ago - will have caused mass extinctions ( 99.999% of animal life that has ever existed in now extinct).

The present global warming could cause our own extinction - or the crops and animals that we depend on - and so change our civilisation for ever !!

Answer 4

Not all species survived previous climate change. Humans are already fighting over resources. Food prices are rising and there have been food riots in India. There are tens of thousands of unburied corpses in Burma - that's how epidemics start. Do I have to continue?

There is no reason to assume that the human species will survive.

Answer 5

The climate is always changing, sometimes getting warmer, sometimes colder.  probably the most recent significant warming event is the sharp warming that occurred about 12,000 years ago (and NOT hundreds of thousands of years ago), which caused the massive melting of continental glaciers and a huge rise in sea level (more than would result from melting all of the ice remaining today).  Humans thrived from this warming and basically all of human history is the record of how man benefited from that global warming.  It is no coincidence that civilzations started in the few thousand years after that big melt-it is in fact the primary reason man migrated to river valleys and developed agriculture and all of the other things we associate with being human.

This doesn't mean that the change was easy or that some life forms didn't suffer.  Some died out. Others benefited.

The current global warming will not be the end of the world.  As with any change, there will be differences that will need to be dealt with, but nothing will be as severe as some people would like to scare you into believing.

The climate was warmer than now only about 1500 years ago, then cooled off through the middle ages.  It only started warming back up around about the early 1800's.

it would be foolish to ignore the changing climate, because there will be changes, but nothing that man hasn't already dealt with successfully.  And yes, maybe some plants and animals will fail to adapt.  That always happens.  (doesn't also mean we should go around hurrying along their demise by destroying rainforests etc.)

it would also be foolish in my opinion to overreact and get all excited about something over which we have little control, and which, really, is just normal earth behavior.  We are smart enough to adapt and we shall.  Change is normal.
