Climate change and global warming are both total nonsense and drivel concepts.
Take a look at the mass desertification. The Sahara Desert has grown 10% in less than a century. ("The Sahara Desert Is Growing. Here's What That Means" at livescience). This is largely because of humans killing off plant and animal life and using up natural resources including water. It all goes hand in hand. Think about the endangered animals because of humans. Now think about how their near-extinction or extinction will affect their environment. If the prey die, The predators die. If the predators die, The prey grow too populous, Thus destroying more plant life. Coral reef bleaching events have gone up drastically since the industrial era. Once large reefs (most notably the Great Barrier Reef) are being destroyed from the rising sea temperatures and ocean pollution. You can't accept that pollution and endangered animals are being caused by humans but then reject that all this doesn't affect the climate and the ecosystems of the world.
