Methane's origin
- CH4, a type of natural gas
- major sources: emission from wetlands, microbial digestion, fossil fuels etc
- trying to understand the global methane cycle
Methane's accumulation (phenomenon)
- newly identified source: green vegetation
- research implication: methane level corr. with temperature level
- Ice core example: high CO2 level corr with high temperature
Methane hydrates
- originally thought to be driver of global warming
- however, less correlation
Implication on reforestation strategies
- climactic benefits (CO2 abortion) outweigh negative impact (methane emission)
Conclusion
- core issue for global warming: burning of fossil fuel
