I was reading the global warming article on the Japanese wikipedia and got stuck on this phrase
I looked up the last two words individually, which lead me to an interpretation of: 'world change [i.e. increase] of average temperature deviation over the years'. Is this correct?
I think, from what I've understood in my previous reading, temperature deviation is the difference from a baseline average temperature [pre-1950's from memory]. But as this is the first time I've encountered 偏差 and 経年変化, I'm worried I might be jumping the gun.
Any help would be appreciated. Thanks :-)
Edit: I found out later the baseline temperature is the 1981-2010 average, not that of 1891-1950, as I originally presumed. The caption in the article doesn't explicitly identify this average, which led to a lot of confusion on my part. It would have been helpful if the Japanese article didn't leave this information out.
