Some conservatives don't believe climate change is much of a problem. A 1.5 degree C temperature rise since, pre industrial revolution, doesn't seem that much. Here in USA, we use Fahrenheit scale so it's actually 2.7, in our degrees. A bigger number. Maybe scientists should describe it in our "American" terms.
Still, only 2.7 doesn't seem that much to us. The change comes in well over 100 years, but there are more tangible effects, from this change; such as severe drought in the American Southwest.
California is America's most productive agricultural state. Droughts, for year after year, are likely to end much of California agriculture.
Drought with forest fires threaten to destroy the California redwoods. Those in the Sierra Mountains at least. Loss of a national treasure.
Lake Mead and Lake Powell, on the Colorado River, are running so low of water that 5 states, they serve, have to cut way back on water use. Lake levels, at the dams, are getting so low that there may not be enough "water drop," at the dam, to generate power.
The Southwest could see a few more wet years, but most scientists think the long term trend is "dry" because of climate change. In the recent past, there has been several dry years in a row. This trend may continue well into the future.
Yes, the Earth will survive and it's seen climate change before. The main difference is that we have not seen this type of climate change since the start of modern civilization.
It's the continuation of our way of life and our economy that we should be worried about.
Things can change. California's Sierra Nevada Mountains will survive, but they might become more like dry mountain ranges of Nevada's deserts. The Sierra might become more like mountains of the Mojave Desert farther south.
We, humans, might be able to adapt. I already hear of farmers, in California's Central Valley, who can no longer get irrigation water. They are giving up on food crops and turning the fields over to solar panels.
The world is changing, but conservatives and others alike tend to try and hang onto the status quo.
