Why didn’t God warn us about the climate crisis?

According to all studies, the Earth will warm significantly, the water level will rise, and millions will become refugees, even to the point of extinction of the human race.
The Bible makes no mention at all (to the best of my knowledge) of a climate crisis, and religion does not warn us about it, does not tell us to protect the environment, etc. From this I am debating between three options:
1. If God exists and he hasn’t said a word about climate, then there is no climate crisis and all scientists are wrong.
2. If scientists are right and religion does not warn us of dangers to the Earth and the extinction of the human race, then God does not exist.
3. The Earth will be destroyed in exactly 215 years as a result of climate change, as the prophecy of the seventh millennium says. But it is surprising that the prophecy does not specify how the Earth will be destroyed.
