Climate change is creating widespread animal suffering through habitat loss, food web disruption, extreme weather, and range shifts.
Climate change creates cascading welfare harms: starvation from food web disruption, heat stress, drowning from sea level rise, wildfire trauma, and disease spread. Coral bleaching kills the billions of small fish and invertebrates that depend on reef structure. Walrus forced onto land cliffs from melting sea ice die in mass falls. Every degree of warming expands the scale and severity of wildlife welfare harm.
