A study published on 22 July in the journal describes in detail the relationship between mass extinctions and fluctuations in the average global temperature, and the results have significant implications for the medium- and long-term future, as well as for paleoclimatology and paleontology.
While the link between the rate of climate change and the extinction of plant and animal species is no longer clear, accurate quantification of this link remains a subject of research, especially in the current rapidly global warming climate.
Correlation between extinctions and climate change
Professor Kunio Kayho's work sheds new light on this relationship during the Fanerozo period, that is, the last 540 million years, and a researcher has shown that the rate of extinction of the invertebrates in the ocean and the Tetrapod in the continental region has indeed been correlated with fluctuations in the world's average temperature, be it cold or warming.
", " states the annotations to the study.
The results also show that terrestrial species are more affected by this increase in global temperature, which is consistent with the fact that continents are heatier than oceans, which is also reflected in current warming, and even more so when the temperature changes in the habitat area, marine species show the lowest transportability, and again this characteristic is reflected in current observations.
By the sixth major extinction?
"," said Kunio Kaiho. "
According to even the most pessimistic IPCC scenarios, warming is expected to be no more than 7 °C by the end of the century. It is even reasonable to expect a temperature increase of 7 °C.
"," concludes the author of the study.
It should be noted, however, that not only does man weaken the biosphere by warming the climate, but he is also doing so with his many industrial and agricultural activities, so that this reality can partly offset less warming.
