This was known as the end Permian extinction. Although the cause of this disaster remains unknown, it is very well known that during this period, it was very warm. Ecologist Peter Mayhew of the University of York in England had said that three big greenhouse phases happened in this time, where the peaks in temperatures uncoincidentally coincided with the mass extinctions following the Permian, Triassic, and mid- Cambrian periods, resulting in symptoms such as a rapid jump in global temperatures, rising sea levels, and ocean acidification, all of which are happening today with human-caused climate change. When pairing the data, shows that eras with pretty high concentrations of greenhouse gases were hit tragically, decreasing the number of species on Earth. As far as our opinion goes, we feel as though the initial start of global warming climate change was due to those tragedies all those years ago, but us as people are just as bad at contributing to global climate …show more content…
The levels of carbon dioxide are higher in this time than at any point in the past 800,000 years. Not to mention the last time the CO2 amounts in the atmosphere were this high was a little over 3 million years ago. Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy, such as like coal and oil. Those two fossil fuels contain carbon that plants pulled out of the atmosphere through photosynthesis over the span of many millions of years; we are returning that carbon to the atmosphere in just a few hundred
