VOICE: Carbon dioxideis a greenhouse gas that is heating up the atmosphere. But that’s not the end of the story.
Historically, all the sources of carbon dioxide also emit aerosols, also produce this particulate smog that’s been cooling the Earth. And Dr. James Hansen, who is considered a grandfather of the global warming theory, pointed out that these two emissions roughly cancel each other out.
So historically, we’ve seen roughly zero warming from sources of carbon dioxide so far.
VOICE: So if not carbon dioxide, what is causing global warming? A primary factor is methane, which traps 100 times as much heat as carbon dioxide in the near term.
A recent assessment sponsored by the UN Environment Program and World Meteorological Organization shows that it is possible to curb global warming very quickly by reducing methane emissions.
Along with climate protection, this would also bring significant health, agricultural, and ecological benefits. Researchers note as well that because livestock raising is the single largest source of methane generated by human activities, becoming a vegan is the fastest way to reduce methane emissions, as stated by Dr. Terry Root of Stanford University, USA.
Professor Terry Root, PhD – Senior Fellow, Woods Institute for the Environment, Stanford University, USA (M): We need to decrease the amount of methane that we’re putting up. And one way is to become vegetarian. It really truly makes a difference.
Stop the methane. Stop the real cause of global warming.
