100 Years of Global Temperatures
Below is a representation of average global temperatures for the past
100 years — 1920 to 2019. The
green line represents the average
global temperature for each of the 12 months during the 20th century.
That's effectively 0, or the baseline. All the other lines represent a
year and its position relative to the baseline. The distance of the
line from the green baseline shows the size the temperature difference
from the baseline. All the
blue lines represent years where
the average monthly temparatures were lower than those during the 20th
century. Yellow lines are those
marginally above the 20th century, and
orange and red lines are those
years significantly above the 1900-200 baseline.
Hover over the year lines for more information.
Each of the past 100 years is represented below. Move your mouse over
a year for more information. The blue years are those in which
temperatures were below the 20th century average. The yellow, orange
and red years are those in which temperatures were higher than the
average for the 1900-2000 period.
