Climate Catastrophe
By 2026, accelerating climate change—driven by rising greenhouse gas emissions, deforestation, and industrial activity—poses the greatest existential threat. Global temperatures have surpassed 1.5°C above pre-industrial levels, leading to intensified extreme weather events like megadroughts, superstorms, and heatwaves that disrupt food production and displace billions.
This cascade could trigger societal collapse through mass migration, resource wars, and economic breakdown. Geopolitical tensions over water and arable land escalate, while feedback loops like melting permafrost release more methane, amplifying warming. Without drastic mitigation, runaway climate effects could render large parts of Earth uninhabitable by mid-century, ending civilization as we know it.
