What Caused 'Global Warming' That Ended The Ice Age?

Question

There were glaciers all over the place and they disappeared without 'greenhouse' gas. How did that happen?

Answer 1

Right, warming and cooling are natural cycles.

But it's human nature for man to accept guilt, as it's human nature to exploit guilt. There will always be those that take advantage.

It is the Sun, not co2 that causes warming. No one can tell you if it will be warmer or cooler next year.

Listen to some here and you would think we're entering a "steam age"

Answer 2

hmmm, ok on condition that no person have been given it yet, its the milankovitch cycles. There are 3 cycles wherein the earths axis and orbit differences progressively. there's a coarse a hundred,000 cycle wherein the orbit will become extra elliptical, inflicting us to be farther faraway from the sunlight throughout the time of the top of two of the seasons. we've ice an prolonged time as quickly as we are on the farthest factor away throughout the time of the northern hemisphere summer, and iciness. We get like 21% much less sunlight from the sunlight while on the a strategies factors from the sunlight for the duration of that factor, so which you will think of how which could result the northern hemisphere throughout the time of the summer and iciness. The winters have been brutally chilly and the summers werent heat sufficient to soften the snow %. from the previous iciness. So there is how your ice age occurs. Im no longer likely over the different 2 milankovitch cycles with the aid of fact I dont think of they are as significant with the aid of fact the main, a hundred,000 3 hundred and sixty 5 days cycle, so seem the different 2 up, Im no longer typing it out. The ice age ends with the aid of fact the summers get warmer, and the winters get warmer with the aid of fact the orbit looses its eccentricity, and could become extra around over the years. stunning now, we recieve 7% much less sunlight for the duration of two seasons of the 300 and sixty 5 days, I dont understand how its lined up stunning now, for which hemispheres. It should not be sufficient for absolutely everyone to be conscious.

Answer 3

first of all - there were NOT glaciers "all over the place"

ok the last ice age started when a big chunk of ice broke over Canada... and released a flood of colder water into the NORTH ATLANTIC - this confused the WATER CURRENT of the North Atlantic which normally would bring warm water UP from Equator... so with no warm water coming up north - the northern hemisphere started to cool and hense the ice age

what ended it was a return to the normal current thanks to Antartica - the melting of sea ice allowed more water to be exposed to the sun thus warming the water and returning the currents to normal...

the current threat is CO2 levels which are higher than they have ever been in history (with samples of ice taken from Antartica we can see CO2 levels even back before dinosaur times..)

Answer 4

The planet is a living biosphere not unlike a plant or person. The Heating & Cooling cycles of our planet is its natural respiration, like breathing in & out, which keeps the overall living system in place.

Because we think in more or less human metrics, we tend to look at cycles of 100-200 years, or even 1,000 years, when in fact the heating & cooling cycle is playing out over much longer stretches of time than we are used to applying to our ecological models.

Its no wonder we're having problems keeping our relatively young astrological/agricultural calenders up to date with the ever changing climactic process, which is itself millions of years long, changing and evolving the entire time.

While this causes some anxiety, understandably, its more a symptom of our short perspectives & need to view the ecological 'status quo' as a set of eternal values, which of course, it isn't.

The best thing we can do is minimize impact, each of us personally, and help to educate our communities as an act of compassion for one another, and for the beautiful, ever-changing environment.

Answer 5

The Sun increased it's radiation. Google Milankovic cycle.

How do we know that's not going on now? We measure the Sun (have been for many years). It's actually been decreasing (just a little) for some time. Proof:

Answer 6

Camp fires set by humans.

I have proof.

Humans burned camp fires during the last Ice Age.
The Ice Age ended.
Therefore, human camp fires caused global warming and the thus the end of the last Ice Age.
Quod Erat Demonstandum.

I used the fundamental theorem of AGW theory:

A follows B, therefore, A caused B.

Answer 7

14,000 years ago laurentide melted and great lakes were formed and lot's of article say that when people came to this world the started doing experiment's on earth and building stuff on earth and creating new technology and glaciers melted because of fossils fuels burning and green house gases are being created and the layer around earth is thinning and the sun's rays gets in to earth easily and doesn't go out because of green house gases and it gets warmer in earth and ice melts

Answer 8

SUMMARY: Natural cycles of the Sun and Earth,

EXPLANATION: There's two types of ice ages, for convenience I'll call them full ice ages and mini ice ages.

The full ice age cycle spans approx 125 million years during which times temps swing from a low of approx 5°C to a high of approx 35°C. During the coldest times glacial cover extends, in places, almost from the poles to the equator; during the warmest times the Earth is completely free of ice. In the larger scheme of things, our planet is heading into an ice age and has been for a little over 50 million years.

The mini ice age cycle lasts for approx 100,000 years, we came out of one 10,000 years ago. Back then glaciers covered much of Europe, northern Asia, Canada and northen North America.

The reason we have these cycles is due to a complex series of cycles that both Earth and the Sun go through. You're familiar with the cycles that causes day and night and the cycle that causes the seasons, these are caused by the way Earth moves in space but they're just 2 of the cycles. There are others which last for many thousands of years and it's the interaction between these cycles that causes warming and cooling.

It more complicated than that because these cycles kick start changes on our planet. When it warms or cools Earth is a very differnt places, it can be devoid of almost all life or it can be almost tropical from pole to pole. These changes in themselves affect warming and cooling. On top of that there are positive and negative feedbacks, couplings, trigger mechanisms etc. It all adds up to a very complicated system of changes that lead to warming and cooling.

Specifically you mentioned greenhouse gases. These cause the planet to warm because they have the ability to retain heat within our atmosphere (these gases have the same wavelength as thermal radiation). If temperatures rise levels of greenhouse gases increase, if levels of greenhouse gases increase they cause temperatures to rise, it really doesn't matter which comes first as one leads to the other.

Answer 9

The most likely scenario is the effects of the Sun's magnetic emissions from solar winds, sun spots, X-ray solar flairs, etc etc. were at an very minimum for centuries which kept the Earth's crust very stable. This kept the heat from within the Earth from coming to the surface.

http://volcano.und.edu/vwdocs/vwlessons/lessons/Earths_layers/Earths_layers4.html
View all the pages and see the tremendous heat trapped just a very few miles beneath us. The heat ranges from 1600 degree F to 9000 degree in the cores.
Now anyone can monitor the Sun's activity from:
http://spaceweather.com/

Why is it that Alarmists NEVER mention the Heat within the Earth?
Imagine how cold the earth would be without some of that heat continuing to surface!?!?

Also Google "Maunder minimum" you should see the correlation of sun spots with the 'Little Ice Age'.

Answer 10

Thats a really good question. The Ice age started because an asteroid hit the Earth and spewed dust into the atomosphere. That dimmed the sun and caused the planet's temp to drop. So once the dust settled the sunlight and plantet temp began to rise again and drobe back the glaciers from the middle of the planet where it is warmest.

Answer 11

the sun

which in turn gave warmed and a chance for life to flourish via plants and animals and yes even humans

But certain humans feel there are too many humans and so we need to stop/kill humans from destroying the earth... how twisted is that?
