reasing at a relatively rapid rate. Though detailed studies are lacking, the possibility exists that world climate may be affected. The risk of a serious perturbation appears small, but the problem is only poorly understood and the confidence level in such a prediction is low.Cardiac 发表于 2025-3-27 03:28:57
