July 2100 Climate Model Projections (RCP 8.5) Summary

Climate Model Projection for July 2100 (RCP 8.5)

Global Temperature Projections

• Temperature Scale:

  • The color scale at the bottom of the image ranges from -6°C to 42°C.
  • Blue colors represent cooler temperatures, while red colors represent hotter temperatures.
  • The scale helps to visually understand temperature variations across different regions in the projection.

• Key Temperature Ranges:

  | Color     | Temperature Range (°C) |
  |-----------|------------------------|
  | Dark Blue | -6                     |
  | Light Blue| 0                      |
  | Green     | 6                      |
  | Yellow    | 12                     |
  | Light Orange | 18                 |
  | Orange    | 24                     |
  | Red       | 30                     |
  | Dark Red  | 36                     |
  | Deep Red  | 42                     |
  

Notable Regional Temperature Changes

• High-Latitude Regions (e.g., Arctic, Northern Russia, Northern Canada):

  • These regions are projected to experience lower temperatures (cooler colors) due to their higher latitude positions.
  • Temperature ranges here are generally between 0°C to 12°C.

• Equatorial Regions (e.g., Amazon Basin, Central Africa):

  • These areas display some of the highest temperature projections, often ranging from 30°C to 42°C.
  • The intense red and deep red colors suggest extreme heat.

• Mid-Latitude Regions (e.g., United States, Southern Europe, China):

  • These regions show significant warming, with temperatures likely between 18°C and 36°C.
  • Orange to red shades dominate, indicating considerable heat.

Climate Scenario Context

• RCP 8.5:
  • The image projection is based on the RCP (Representative Concentration Pathway) 8.5, which represents a high greenhouse gas emissions scenario.
  • Under this scenario, it is assumed that no significant efforts are made to reduce emissions, leading to rapid warming.
  • RCP 8.5 is often referred to as a "business as usual" scenario, highlighting the potential impacts without climate change mitigation.

Future Implications

• Human and Ecological Impacts:
  • Extremely high temperatures in regions like the tropics and mid-latitudes can lead to severe heatwaves, affecting human health, agriculture, and biodiversity.
  • Regions that experience substantial cooling might face different challenges, such as altered weather patterns and ecosystem shifts.

Summary

• The image provides a visual projection of global temperatures for July 2100 under the RCP 8.5 scenario.
• It emphasizes the variability in temperature changes across different regions based on the emission scenario.
• Understanding such projections is crucial for planning and implementing climate adaptation and mitigation strategies globally.
