Permian Extinction 250,000,000 years ago
Siberian traps, volcanic erruption 500,000 years
Lava
Ash
Can travel far
Kills by suffocation
Gas
CO2
Global warming
SO2
Mixes with H20 to make H2 S04
Acid rain
kills organisms or destroys food webs
H2 SO4 in the clouds reflect sunlight
Freezing cold
Burns
Extinction Results:
95% of species died
Land ecosystems collapsed first
Ocean ecosystems collapsed second
Many organisms could not adapt
Climate Effects:
Acid rain damaged ecosystems
Sunlight reflected → freezing conditions
Later greenhouse warming occurred
Equator regions became deserts
Greenhouse Gases:
CO2 released from volcanoes
Methane released from ocean depths
Methane was 20–25 times stronger than CO2
Global temperatures rose about 5°C more
