Projected Thermal Habitat

Sharpnose Shark

The animations on this site show projected distributions of suitable thermal habitat for fall based on the NOAA Geophysical Fluid Dynamics Laboratory's high-resolution global climate model (CM2.6). In the 80-year model run, atmospheric CO2 increases by 1% per year and doubles by year 70. This results in a global surface warming of 2°C (3.6°F), which is equivalent to the 2060-80 time period in the IPCC's RCP8.5 (highest emissions scenario). Therefore, the time steps (60-80) correspond roughly to the years 2060-80 in the IPCC’s RCP8.5 emissions scenario. It is important to note that these are ONLY projections of thermal habitat and DO NOT include other important factors such as fishing mortality, species interactions, and bottom-up forcing.

NOTE: The color scale is unitless; larger values simply represent more suitable thermal habitat.
