Soil carbon stocks in Sarawak, Malaysia
The relationship between greenhouse gas emission and climate change has led to research to identify and manage the natural sources and sinks of the gases. CO2, CH4, and N2O have an anthropic source and of these CO2 is the least effective in trapping long wave radiation. Soil carbon sequestration can...

The relationship between greenhouse gas emission and climate change has led to research to identify and manage the natural sources and sinks of the gases.
