The authors use FUND 3.9 to estimate the social cost of four greenhouse gases-carbon dioxide, methane, nitrous oxide …, and sulphur hexafluoride-with sensitivity tests for carbon dioxide fertilization, terrestrial feedbacks, climate … potential for each gas-the ratio of the social cost of the non-carbon dioxide greenhouse gas to the social cost of carbon …

Biochar is the carbon-rich product produced by thermal decomposition of organic material in anaerobic conditions or … under limited supply of oxygen. The removal of pollutants from water using biochar materials is a low cost, sustainable … grain size. The impact of pH, biochar adsorbents amount and phase contact time on the adsorption efficiency were …
