Scientists have initiated to estimate the coldness in Earth’s temperature at the time of its last Ice Age. During the period, massive ice sheets enclosed large portions of Asia, Europe, South America and North America. The researchers have strived to calculate the temperature with the help of the climate models and ocean plankton fossils. According to their findings, the polar regions cooled a way more than that of the tropical regions. They even stated that the Arctic regions were 25 degrees F stonier than the average universal temperature. The researchers have discovered more exciting details on the news piece, keep on reading to know them all!
Details on the Last Glacial Maximum
During the period of Earth’s last Ice Age, the average universal temperature is called Last Glacial Maximum. The time is around 23,000 to 19,000 years back from now. Yesterday, the researchers claimed that the then Earth was approximately 7.8 degrees Celsius. To be precise, it was 7 degrees Celsius colder than last year’s average temperature.
Things the scientists used to conduct the research
Scientists especially pointed at some certain regions to be colder in comparison with the average global temperature. The researchers performed the calculation with the help of the chemical measurements on the tiny zooplankton fossils. They even made use of the preserved fat structures of other kinds of plankton to conduct the research. Those planktons can alter in response to the temperature of the water. In the language of science, the researchers call it a “temperature proxy”.
Reports on the findings of the research
While discussing the outcome of their research, the scientists stated that the past climates are only information they have regarding the happenings when Earth warms or cools. Hence, they can estimate the anticipation of the Earth temperature in future by studying those climate details. They further stated at the last Ice Age period that existed from around 115,000 to 11,000 years back, mammals suitably adapted with the cold climate. The animals including mastodons, woolly, mammoths, sabre-toothed cats, and rhinos managed to survive. As per their statement, human beings stepped into North America during that period for the first time.
