The colloquium was conducted by Nalaka Gunawardena. The colloquium began by Nalaka explaining the big picture; Climate change and energy use. Global warming is not new but the rate of global warming is. There is a multiplicity of gases causing global warming and their sources. Looking at the Green House Gas (GHG) mix, Carbon Dioxide is dominant.
We have written about this endless loop of reasoning before. But I guess someone thinks this perpetual motion exercise does some good. AVIATION has long been blamed for its share of anthropogenic global warming. Indeed, some travellers now ask themselves whether their flight is strictly necessary and, if they decide it is, salve their consciences by paying for the planting of trees. These, so they hope, will absorb the equivalent of their sinful emissions.
