Unlike what we had previously thought, decreasing the amount of pollution in the air from soot and methane may not provide much relief to the environment. A new study reveals that the US Government’s efforts to slow global warming may not yield any significant benefit despite many scientists previously hoping that it would.
The US is currently trying to put new regulations into place which will limit the toxins that factories can put into the air, but this effort may end up being futile. Researchers with the US Department of Energy wrote:
Reductions of methane and black carbon (soot) would likely have only a modest impact on near-term global climate warming.
According to the report, “modest” means that decreasing pollution from soot and methane will result in a decrease in temperature rises of just 0.29 degrees Fahrenheit by 2050. Previous reports had suggested that the impact would be far higher and that decreasing pollution would result in temperature rises being decreased by 0.9F.
Instead of these partial changes in common polluting practices, the study’s authors stated that a “comprehensive climate policy” would be needed to have a real impact on global warming.
This new policy would have to be adopted by virtually every country and would place limits on all greenhouse emissions. However, there is a lot of evidence to back up other points of view regarding soot and methane.
The UN Environment Program has stated that cutting short-lived pollutants such as methane and carbon could result in the prevention of nearly two million avoidable climate-related deaths each year as well as save millions of crops.
Two of the biggest culprits when it comes to pollution are China and India. Unfortunately, the governments of both countries feel that cutting short-lived pollutants is not incredibly important and therefore they have refused to join UNEP.
Whether or not these latest reports are correct, the world is facing a major global warming crisis which needs to be addressed in a more serious manner. This means that people need to at least stop denying the existence of a problem.
