Coming soon -- future projections

• Projections downscaled from IPCC forecasts using Angelica's ROMS model
• On a 1/64th degree grid
• Surface and bottom temperatures
• Done by Trond Kristiansen et al., contract through Robyn Forrest

Three future socio-economic pathways:

• SSP1-RCP2.6 -- r colorize("sustainable development")
• SSP2-RCP4.5 -- r colorize("middle-of-the-road development")
• SSP5-RCP8.5 -- r colorize("fossil fueled development")

\pause

Think we will have monthly averages, corresponding to time periods:

• 2021-2040
• 2041-2060
• 2080-2090
• or maybe just 2050 and 2090
