Global Warming: CH4 vs CO2
A presentation by
Elijah Adamos Joseph Lara
Global warming:-increase in global average surface
temperature…
What is a more potent greenhouse gas?Methane?Caron dioxide?
• Methane CH4 = 1.866ppm = 0.008432ppm yearly
increase (1981-2008)= molecule traps heat
20 times more effectively than CO2
= radiative forcing 0.48 W/m2
• Carbon Dioxide CO2
= 386.3ppm = 1.6837ppm yearly
increase (1981-2008)
= radiative forcing 1.66 W/m2
Surface Air Temperature
Methane
Standard deviation: 1.186
Surface Air TemperatureCarbon Dioxide
Standard deviation: 0.2361
Net Heating
Methane
Standard deviation: 1.292
Carbon dioxide
Standard deviation: 2.498
Conclusion
According to the models:
1.Methane causes greater surface air temperature changes.
2.Carbon Dioxide causes greater heating.
Methane increase from Arctic melting?
No.
