The City of Corner Brook might not be among the first places that come to mind when one thinks of volcanoes, but that s not Donald Dingwell s fault.
The volcanologist, who is originally from Corner Brook, has been elected to the prestigious Royal Society of London an honour enhanced by the history between Great Britain and his home province, he said. If you come into the Royal Society, it means they re inviting you in from far away. I don t work in the U.K., never did, but I think that element of it gives it an extra level of gravity, Dingwell told CBC News in a recent interview from his home in Munich.

Greenhouse gas emissions from livestock production vary greatly in different parts of the world due to farming practices as well as animal numbers, type and food product. A new study finds emission intensity for the amount of protein produced could be reduced through more efficient farming practices, even as demand rises worldwide.
Adopting a plant-based diet can help shrink a person’s carbon footprint. But a new study finds that improving the efficiency of livestock production will be an even more effective strategy for reducing global methane emissions.
The new study looked at the intensity of methane emissions from livestock production around the world – in other words, how much methane is released for each kilogram of animal protein produced – and made projections for future emissions. The authors found in the past two decades, advances in farming have made it possible to produce meat, eggs and milk with an increasingly smaller methane footprin
Plus, bad news for Americans already complaining about the heat, global food production is projected to shrink by a third by 2100 and an even better idea than reforestation – not chopping trees down in the first place
