ERSC 1F90 Lecture Notes - Lecture 14: Conservation Of Energy, Soot, Flatulence
Document Summary
Anoxia (lack of oxygen) and global warming were the two most probable causes . Major trigger for global warming: siberian flood basalts. 6 million km^3 (volume) (would cover basically much of the. Gasses come along with the basalt such as co2 and methane. Employed many screening tools which started at visual inspection in the field. Petrography: can look at something through a microscope. The more evidence you have of how something is preserved the greater the continence will be robust and tell the original story. Global warming tropical seas >40 degrees celsius. Now in 2016 we are over 400 ppm. If the planet is warmed, the ice is melted and sea-level rises, if all the sea ice was melted it wont cause a change but the melting of continental ice will change sea levels. Global change in seawater temperature ~1 degree celsius (0. 67 degrees in 100 years) Albedo: ice melting feedback, permafrost feedback.
