And that was a volcanic eruptions that triggered global warming to wipe out 96% of marine species. It resulted in a rapid sea-level changing, volcanic eruptions and global warming occuring during the period.
- 70 million years ago, during Cretaceous Era, Earth was going thorugh greenhouse phase. There was an increase of CO2 in the atmosphere that resulted in ocean circulation changed direction in the Atlantic Ocean with two water masses
- Now adays, we can still see the climate change occuring by looking at ice cores of tropical,Antarctica, and greenland mountains and identifying how they are responding to the changes in greenhouse gas levels. Additionally, we can also take a look at tree rings, layders of sedimentary rocks, and more to find the evidence of climate changes.
