Are there any non-detrimental effects resulting from climate change?

I recently read that due to climate change, certain plants will start growing again in areas that could not have grown for thousands of years. Are there any other effects that could be seen as objectively positive in regards to diversity of species, species populations, or other misc. factors generally regarding the "health" of the planet?    
Btw; I am not trying to bait a "is climate change real" debate here; I believe in climate change and that we should avoid it, I just want to learn more about the side effects.

There will likely be a lot of changes, probably many that are good locally, probably lots that are bad locally and globally. Human civilization has adapted to the present climate conditions, so any significant change, good or bad, is likely to disrupt a lot of things, especially food production. Disruptions in food production leads to famine, which leads to war and mass human migration. Which disrupts stuff elsewhere.

For example, it has been postulated that nordic countries will experience longer, warmer summers and milder winters, which can be considered good regionally. However, if somewhere else millions of people have to relocate, the same nordic countries begin to seem like a paradise to climate refugees. If they then descend en masse to these countries, their societies may collapse from the massive demographic shift.

Eventually humans will adapt to whatever the new climate is once stabilized, but the transition may be catastrophic.
