In that case I am sorry I discounted your post, do you happen to have some links I could read? I know mercury can contaminate the reservoir's water and that it has been an issue for some northern communities, but I never heard of the methane thing.
- soperj 5y agoI've posted one. https://link.springer.com/article/10.1007/s11027-005-7303-7 https://link.springer.com/article/10.1007/s11027-005-7303-7 I'm happy to be completely wrong on this, but I don't see why it would be true for a dam in Brazil vs. a dam in Canada. BC Government has never studied it. There's absolutely zero incentive for either province to do the research on it.

The springer link unfortunately doesn’t have any numbers for tonnes to compare but mentioned lush Amazon rainforest being flooded and the vegetation at the bottom producing the most methane which is 25x more potent ghg than CO2, resulting in 3.6x equivalent warming than due to burning coal which primarily results in CO2. 0: https://www.visualcapitalist.com/uranium-powering-the-cleanest-source-of-energy/ https://www.visualcapitalist.com/uranium-powering-the-cleane...
