Naturally, without any human influence, we would expect the new ice age to start 50,000 years from now. We may never have another ice age. During the latest ice age, the cooling period (the glacial period) started about 125,000 years ago and lasted until 22,000 years ago, when there was the maximum extent of ice cover. There are two factors determining when the next glacial cycle. For hundreds of millions of years, the planet had no polar ice caps.
Without this ice, the sea level was 70 meters higher. (via TEDEd) Throughout Earth’s history, climate has varied greatly.
The first concerns the natural cycle that has been at play since the beginning of our present day Ice Age (about 2.6 million years ago). For the moment at least, the onset has been halted and the planet is in fact warmer now than at any time since the ice-age … I believe that is when there is an increased probability that the current interglacial would come to an end and ice sheets will start growing in Northern Canada. At the other extreme, about 700 million years ago, Earth became almost entirely covered in ice, during an event known as “Snowball Earth.” What causes these swings in the planet’s climate? Hi! But CO2 emissions affect the development of such ice sheets. There are actually quite a few complications with the terminology, so let me start from there. In this case the next glacial period ushers in as temperatures in the worlds oceans rise that in turn increases hurricane activity/force. This is a really good question! – From a glaciology point of view, an “ice age” is a period of time when we have ice sheets both in the northern and southern hemisphere. Our next appointment with the ~ 2400 yr solar cycle is in 2000 years. The next Ice age can happen anywhere from 100 000 to 500 years, depending on how we react to global warming. To answer your first question – the onset of the next ice age began 8,000 years ago and will reach it’s trough (coldest) in about 80,000 years time. At what age would be appropriate for children to begin thinking about their futu by Cagsil 8 years ago One of the biggest problems in many societies around the …
