The first half of the 21st century was a golden age for the ice ages.
At the end, the ice sheets had thinned to an extent that they could no longer support massive amounts of sea-level rise.
The planet had warmed to such an extent, the climate system was more stable and the glaciers were starting to recede again.
In other words, we had a great time.
But what about the last half of that time?
What happened to all those ice sheets?
And what happened to the oceans?
And why did the oceans rise during the last ice age so much faster than the rest of the planet?
In an effort to find out, I went looking for the answer.
I was interested in what happened during the Ice Age when the ice melted and the ocean was formed.
It was a difficult task, because the ice that was left was unstable.
It had been exposed to some of the elements that we now consider dangerous.
For instance, methane and ethane had been released from the permafrost that had been buried by glaciers.
So when the permakite started to melt, the permashite melted into a mixture of carbon dioxide and water.
Then, methane was released, and the water froze solid.
The permashites were eventually broken apart and the permacite was exposed to sunlight and the ice was exposed again.
This process happened over several millennia.
However, I wanted to understand how quickly the melting happened and how much the oceans were affected by the melting ice.
In my view, the last time the ice sheet had melted was about 9,000 years ago, when the Earth was only about 10 million years old.
At that time, there was still ice on the Earth’s surface.
However in the last 10,000 to 15,000 or so years, the amount of ice melted has increased significantly, and we have had to build up the oceans to support them.
So what happened?
We have a number of possible explanations for the changes that have occurred during this last ice period.
The first is that the Earth has been experiencing an extreme cooling.
As the climate warmed, the Earth cooled even more rapidly.
As ice melted, the surface temperature of the oceans dropped.
The oceans were more salty, the water was more saline, and there was more acidity.
At this point, the oceans had not yet become saturated with seawater and the saltier water was less able to hold the water as the oceans became more acidic.
This was the first sign of a change in ocean chemistry that led to the ice retreat.
In fact, there is evidence that the oceans in the northern hemisphere had been more acidic than the oceans south of the equator during this period.
This change in chemistry has been observed since at least 4 million years ago.
So the last decade of the last Ice Age had an effect on the ocean.
However it was not as big as we thought.
During this period, we have seen an increase in the amount and severity of tropical cyclones and hurricanes, which have a lot of influence on the flow of ocean currents and the direction of currents.
But it is important to remember that this change in circulation is the result of the changing ocean chemistry and that it is not the cause of the changes in ocean circulation.
Another major change during this time was the melting of the polar ice caps.
During the last glaciation, glaciers retreated as the climate cooled.
Now the ice caps are recovering and they are not retreating as rapidly as they used to.
This means that the amount in the oceans is growing.
In some places, the change is more rapid than we thought, but this is not true everywhere.
In the North Atlantic, where the glaciers are retreating, we are seeing a lot more melting.
This is because the Arctic sea ice is shrinking.
In this region, the Antarctic ice is recovering as well.
This shows that the polar regions are still very important in determining the circulation of the ocean and that there are other regions of the world that are changing more rapidly than we have been seeing.
We can only understand how the ice is changing because we are observing it.
The ice is melting because of changes in the Earth system and the climate.
We know that we are causing a change because we have warmed the planet and the oceans are rising.
However we cannot say for sure what the climate change is because we can’t see it.
There is no real way to measure it.
We do know that the temperature of water in the atmosphere has increased.
So, it is likely that the temperatures of the Earth are rising because of our warming of the atmosphere and the greenhouse gases in the planet.
In our view, we can only use this evidence as a starting point for future research into the processes that lead to these changes.
The next step is to measure the change in the climate in the polar areas.
We are seeing some warming in the Arctic, and this is due to the increase in greenhouse
