Arthur — you are the one who goes too far. The loss of biodiversity and the extinctions you blame on Climate Change almost all happened in the 19th Century due to colonialism and introduced species. Cats in particular have wiped out many native birds and animals from the Americas, Australia and Pacific colonies.
Sea rise at the rate of 1.3mm per year will eventually raise the sea level by 10 metres, but it will happen gradually over the nest 8000 years, and only if another Ice Age doesn’t start before then. Hardly a Climate Emergency!
