I'm not sure we need two different tags. Most everyone uses the verbiage
climate change and not
global warming nowadays (at least in politics). I'm not sure there's a good case for having separate tags for political discussion purposes.
Yes, but: The lemma on Wikipedia is Global warming:
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is a major aspect of climate change and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. Global warming and climate change are often used interchangeably. But, more accurately, global warming is the mainly human-caused increase in global surface temperatures and its projected continuation, while climate change includes both global warming and its effects, such as changes in precipitation.
I consider climate change an euphemism.
So it should be the other way: Make climate change a synonym of global warming.
This question was asked more than two years ago, but I was just about to ask the exact same question when the "similar questions" box showed me this just before posting.
I think in politics and everyday discussion the two terms are synonyms. It only makes sense to distinguish between the two from a scientific viewpoint. At the moment we have 50 questions tagged with climate-change and 14 questions tagged with global-warming (5 questions have both tags), so I feel that global-warming should be merged into climate-change.
I can see here that someone already proposed climate-change as a synonym for global-warming, so exactly the other way around. This proposal doesn't seem to have any upvotes yet. I would downvote it and propose a synonym on climate-change, but I can't due to lack of reputation on the tags.
Global warming refers only to the Earth’s rising surface temperature, while climate change includes warming and the “side effects” of warming—like melting glaciers, heavier rainstorms, or more frequent drought. Said another way, global warming is one symptom of the much larger problem of human-caused climate change.
