Methane and Black Carbon - Essay Example

The results indicate that methane measures are able to reduce the projected global mean warming by 0.5°C by 2050. It also leads to an increase in annual crop yields by approximately 30 to 135 million metric tons as well as a reduction in projected global mean warming by 0.5°C by the year 2050 as a result of reductions in ozone in 2030 and beyond.
On the other hand, BC measures are able to provide significant global climate benefits; however, uncertainties are much larger. In addition, it leads to a reduction in disruptions in the regional hydrological cycle, improved agriculture yields and large regional human health benefits. The fact that these policies help in the protection of food supplies and public health, as well as mitigation of climate change, may aid in motivating policies to be implemented on the same.
Methane and BC measures are complementary to and distinct from CO2 measures. Early adoption of CH4 and BC measures has little impact on long term temperatures but provides much larger short-term benefits. Mechanisms such as the Prototype Methane Financing Facility and the Clean Development Mechanism under the United Nations Framework
Convention on Climate Change reduces CH4 emissions. Because such measures can provide agricultural benefit, improve health, slow the rate of climate change and enhanced warming mitigation necessitates their early and widespread implementation in order to realize such benefits.
Discussion question
How do methane and black carbon measures compare to carbon dioxide–reduction measures in influencing climate change? What are the impacts of implementing both measures?
