It's relative to 1981-2010 baseline. Negative is lower, positive is higher. In 1995, presumably, it was also the average temperature for the 1981-2010 time. The two colors are negative and positive, a potentially unimportant dramatization. Clarifying based on what I understood: Data from 1940-today show that the period from 1985-today had 8x more heat added than the period from 1958-1985, and that each decade since 1958 has increased in temperature. |
