In general, liberals and younger people are more concerned about climate change than conservatives and older people.

Explanation:

Climate change has been becoming an ever-growing issue during the 20th century and continuing into the 21st century, and rightly so. Human activity has managed to do a lot of harm to nature and cause a total transformation of whole regions, which also has had climatic influences. The amount of greenhouse gases that are released into the atmosphere is speeding up the natural process of warming up, which can have catastrophic consequences.

Not all people share the same views on this though. The liberals and younger people tend to be highly concerned about climate change, or rather the influence of humans on it. Their concerns are based on the damage that the humans are doing with their activity, though in some cases there are fractions that are very extreme in their views. On the other hand, conservatives and older people tend to be less concerned about this. Generally, they claim that the human impact is like a drop in the ocean and that with or without it there will be climate changes caused by natural factors. Also, they also tend to put economic progress in the first place.
