The earth's climate goes through cycles and that's one of the main reason some people aren't willing to accept global warming as Al Gore would have us accept it. The reality is recorded history on climate only goes back 150 years or so. We can guess somethings based on soil composition and other geological features. But the further back we go the less certainty there is about what happened.
And there is also the possibility our climate is affected by minor changes in solar output, the rotation of the earth, the temperature of the earth's core, and many other aspects.
Just remember the ice age that ended about 10K years ago didn't completely cover the earth in ice. In the northern hemisphere the ice only came down as far as the northern part of the US. So the tropical areas would have still been warm and had plant and animal life.
Maybe the end of the ice age was triggered by a massive forest fire or a volcanic eruption or even a large meteor hit.

The earth goes through cooling and warming cycles. Despite what Al Gore would say, eventualy we will have another Ice Age. The last ice age ended after the cooling cycle ended. The cause of this is comlicated and is likey due to periodic fluctuations in solar output that some scientists believe corespond to cooling and warming cycles on earth. So if the Sun started putting out more heat, then the ice would melt. The earth today is actually several degrees cooler than it was during medieval times so even within the larger warming and cooling trends there are fluctuations up and down. There have been many ice ages, not just one.

There are variations within glaciations, "ice ages". The warmer cycles are called interglacials - or "global warming" to Hollywood and Al Gore who haven't taken a look at earth history aka geology. Glaciations and interglaciations occurred long before humans' existence.
An understandable phenomenon in human history is the ending of the viking heyday about 1000 AD when cooling of that last "little ice age" altered the currents Vikings used as sea channels, to include the abandonment of Greenland settlement.
Google "year with no summer" and learn about the northern hemisphere in the year 1816. The last "little ice age" only ended about 150 years ago. One can see in photos and museum collections that people began wearing less since the US Civil War.
Attempts to give new phrases and wording to geologic processes, with the pretense that humans cause geology - and to ram political nonsense like that down dummies' throats without the basic explantions is dishonest.
It would be correct to discuss climate change as normal and inevitable since that is the planet's history. Change happens.

I think whenever earth quak came the lava or you can say the magma came out of the core so the hit came out about 6000 degree celcius which made a warm wether. The earth quak happened again and again so the wether got warmer thats why the ice age came to the earth. Iam not sure about this. I Just guess so.

There are natural changes in climate, of course.
But the data shows that the rapid heating going on right now is mostly unnatural, mostly caused by us, and presents a danger to our modern society with massive development in low lying coastal areas and intensive agriculture.
Climatologists include things like natural change, solar radiation, volcanoes, etc. in their analyses. Considering all that they still think the data clearly shows that global warming caused by us is real.

Some geoscientists believe we are still in an ice age since glaciation, even at the polar regions, is a rarity in the Earth's history. (Psst, don't tell Al Gore that, he feels vindicated for what happened in 2000, holding that statute in is energy wasting mansion.)

The earth goes through warm and cold cycles, some are every 10k years. That or alot of farting cows....whichever explaination you want.
