Climate Change is Making It Harder to Predict Fall Colors in National Parks
A study found Acadia's peak foliage now arrives almost two weeks later than in 1950. Across national parks, heat, drought, rain, and shrinking snowpack are making historical peak dates less reliable for fall travelers.

Humans rarely destroy wildlife because we hate it. We drain wetlands because we want farmland.
We divert rivers because we want water. We clear forests because we want timber, housing, or energy. We remove predators because they interfere with livestock. We fragment wildlife habitat because roads and development serve
our purposes.
The other species are not usually the target. In fact, they often are not even an afterthought. We destroy most species without ever knowing they existed. They are simply collateral damage.
That is also at the heart of many fears about artificial intelligence. The concern is not necessarily that AI will become angry at humans or decide that we deserve extinction. It is that a sufficiently powerful intelligence could pursue its own objectives while treating human needs as secondary or ignoring them completely.
It would not have to hate us. It would only have to value something else more. For thousands of years, that has been the human relationship with much of the rest of life.
