Dietary Guidelines Committee ignores climate change

Dietary Guidelines Committee ignores climate change

in the context of climate science is anything which changes the balance between energy arriving and leaving the planet. The global area of ice has a huge forcing because of its reflective properties. Likewise, the type and extent of dust in the atmosphere for the same reason. Livestock change climate forcings directly by effectively taking a carbon atom from carbon dioxide (CO2) and turning it into methane (CH4). A carbon atom as CH4 traps about 25 times more heat than when it is in CO2. In effect, livestock turn single bar radiators into 25 bar radiators. Natural processes will eventually transform the CH4 back into CO2, with about 80% being turned back into CO2 after 20 years. Livestock methane production is measured in tonnes and a tonne of CH4 has far more atoms than a tonne of CO2. All up the warming impact of a tonne of CH4 is about 70 times that of a tonne of CO2 ov...
