Global warming... global cooling... every climate model shows earth cycling through both regularly. Not many thousands of years ago polar ice sheets came all the way down into what is now the northern states of the USA. There are also fossilized remains of tropical palm trees in Siberia. Less than 150 years ago the northern hemisphere came out of an ice age. A vast rain forest became the Sahara, which, at 3.5 million square miles, is the largest desert in the world, and this happened long before the advent of modern technology.
Are we good stewards of Earth? No.
Global warming? Yes, it happens as often as does global cooling, which is now what we are in. In the '70s the panic was another ice age, then there came the panic that the world would end in global warming. Then the world began cooling, so the panic terminology changed to become "climate change." Lol!
