NASA has conducted research that shows that there are 14 air pollution control measures that could be implemented to help slow down climate change while also improving health and helping to increase agricultural production.
The team was headed by Drew Shindell who used an international team to consider roughly 400 different measures that could be used. Out of these, 14 were seen to have the biggest potential for getting climate change under control and reduce pollution that would help to repair the ozone as a side effect.
Carbon dioxide is the gas that is most held to account for global warming and therefore the quest to limit black carbon as well as methane are seen as positive actions. This would help to protect areas that have large areas of snow or ice that could be threatened if temperatures continue to rise.
This would also help with improving agricultural production where it is thought that Southern Asia and the Sahel region of Africa would see most benefits. The improvement in agricultural production would come about through the beneficial changes that would be seen to precipitation patterns by reversing climate change.
Unfortunately, there are many different sources of black carbon and methane and it would take more than just one measure to reduce them. It would require huge changes across the world through machinery, infrastructure and society in general. Some strategies that have been formulated involve capturing escaping gas while others involve updates in technology, higher efficiencies and stricter limitations.
Advanced computer modelling was used to see what the true impact of reducing emissions would be. They clearly showed huge benefits from the reduction of carbon and methane although obviously some areas were more affected than others. It is hoped that the information processed so far through the research will be able to firstly show the true benefits of reducing our emissions and therefore act as more of an incentive to start making changes to the way we live on Earth. It is hoped that the continued research and study will also lead to formulating strategies and ideas that will really work to reduce specifically black carbon and methane emissions.
These changes are likely to have a large impact on our lives. The changes required to be made will see huge change in our everyday lives and in the way that we live in general, but the models clearly show that the benefits from doing so can lead to a longer, healthier life for Earth itself.
