Thanks to new research a better understanding has been gained on the extreme ranges of temperature that the planet has undergone at a CO2 centered thawing of the iceman.
Experts who study Deep Time
History has been very harsh on Earth’s climate, and consequently temperature variations affected the advancement of life forms in orbit. Co-directed by the Smithsonian Institution and the University of Arizona, the report gives the first such information on the temperature changes the globe has been exposed to in the last 485 million years.
This study reviews the Phanerozoic Eon which is characterized by the evolution and expansion of life and episodes of mass extermination. The authors have developed the most comprehensive temperature curve to date by integrating data from a range of geological proxies and computer modeling and demonstrates the degree of climatic volatility that has existed on Earth in times long gone.
Tipping Point: CO2 Emissions
After a detailed comparison of the data, it is clear that it is the carbon dioxide that remains in the atmosphere that holds the ultimate control over the global temperature for vast geological time periods. Such superheated spells were offset by excessive warming linked with the extra levels of this gas illustrating how devastating its effect can be in controlling the climate of the earth.
Strangely, the scientists also came to the conclusion that more or less 15 degrees Celsius is the current and average global temperature of 59°F is actually a warm cooler period compared to most periods during the Phanerozoic Eon. Currently though, the speed in which humanity induced climate change is causing the Earth to warm up is within a range of ideas much faster than even the fastest as under the deep history of the earth. This sort of climate change is still a great danger to species’ and even ecosystem’s which already adapt to the relatively low climate of the present day which is not extremely hot nor cold.
In Conclusion
This ground-breaking research, in addition to explaining in detail how many years the climate of our planet has changed by, also emphasizes where the key importance of temperatures getting to, and the raising of CO2 in the atmosphere which concerns emmits takes place. In the course of dealing with the consequences of the climate change of the present, this understanding of the aggressive nature of the history of the humanity’s only home may be fully useful in terms of protection from the not so far away consequences of global warming.
