A new study shows that the recurring cycles of the ice age apparently go hand in hand with changes in the earth around the sun. Accordingly, the planet would move to another worldwide ice age in about 10,000 years. But greenhouse gas emissions can change the time …
About 2.5 million years ago our earth came in an era of successive ice days and warm phases. The last major enamel ended about 11,700 years ago. The new analysis now suggests that the next ice age could use in around 10,000 years.
The prediction is based on a new interpretation of small changes in the road of the earth around the Sun: “These lead to mass climate changes for thousands of years,” reports a research team, which also reports scientists around Stephen Barker of Cardiff University and Lisraine Lisiscki of the University of California) in Santa).
New insights into the climate system
The study strives for the natural climate cycles of our planet for more than a million years and offers new knowledge of the dynamic climate system of the earth. In the analyzes, more than a million years were taken into account in the analyzes. The researcher documented both the size of the continental ice shields in the northern hemisphere and the temperature of the deep sea.
“These changes can be associated with cyclical variations in the form of the orbit of the earth, the waist movement and the slope of the axis of the earth,” says the UC Santa Barbara website.
Discovered foreseeable patterns
“We have found a predictable pattern for the time in the last million years when the climate of the earth between ice ages and mild warm times as today – the so -called intermediate ice times – is quoted,” the geoscienter Lisiscki is quoted. According to this, a kind of change in the Earth flash was responsible for the end of the ice ages, while another was associated with their return.
Predictions about a connection between the Sunway of the Earth and the fluctuations between ice ages and intervening ice ages have been around for more than a century, but they were only confirmed by real data in the mid -1970s.
Since then, the scientists have had a hard time determining which orbital parameters are most important for the beginning or end of ice ages because it is difficult to date in the past in climate.
Earth is currently in the middle of the interim ice age
The research team now showed that every glossy of the last 900,000 years follows a predictable pattern. This natural pattern indicates, without taking into account greenhouse gas emissions, humanity is currently in the middle of a stable interim and that the next ice age would start in approximately 10,000 years.
