are there any recorded global warming activities in the cambrian period

    The Cambrian Period was witness to an evolutionary explosion of species, largely because of the changing climate. Scientists are not 100% sure what caused this “biological bonanza,” but some speculate that the numbers of photosynthesizing cyanobacteria and algae, which emit oxygen into the atmosphere, were able to “fuel the growth of more complex body structures and ways of living.” The climate also warmed at this time, raising sea levels and creating a more bio-friendly environment.

    During the Cambrian period, the earth was at one of its warmest periods in its history. There were very high sea levels. The carbon dioxide levels were at 7500 parts per million (ppm), which is about 20 times higher than recent levels.
