Simulated Historical Annual Average Stem Dry Mass
1986 to 2005
Why is this time period used?This historical period represents the current or recent climate, spanning enough time to capture variations that impact productivity, such as severe droughts and cool seasons.
Projected Change in Average Annual Stem Dry Mass
Time Period: 2020 to 2039
(compared with 1950 to 2005)
What is this comparison period?Future changes are determined by comparing model projections for each 20-year forecast period against climate model baseline data, which simulates conditions over this period in the past.
Reduced Levels (Moderate)
What is this emissions scenario?Under reduced/moderate emission levels, the total radiative forcing, or change in energy in the atmosphere due to GHG emissions, stabilizes by mid-century. This corresponds to the IPCC's RCP 4.5.
Current Levels (High)
What is this emissions scenario?Under current/high emission levels, greenhouse gas emissions steadily increase through the year 2099. This corresponds to the IPCC's RCP 8.5.
What does this plot show?The time series plot shows the historical conditions and the spread of future projections using two emissions scenarios for your selected location.
