Concepts for my personal project: The Shared World.
In the early 2040's, as giant wildfires ravaged the vast wooded areas of North America and Eurasia, the ash suspended in the air significantly reduced sun rays.
For three years, a cooling comparable to a volcanic winter settled in the northern hemisphere.
The lack of sunlight worsened the long ongoing degradation of soils in northern China, triggering massive dust storms. Without solar energy, many nations massively returned to coal to meet their huge needs for energy. These thermic power plants emit more smoke and toxic particles, feeding the now common winter haze in eastern and southern Asia.
These cold sunless sad winters were remembered as the grey years.
About the pictures:
All the images were composed from collages of photographs and digital painting in Photoshop, processed with Stable diffusion (img2img) or Magnific, then reworked in Photoshop.
