Accumulated pressures from globalisation, geopolitical rivalries, technological acceleration, and environmental degradation set conditions for systemic disruptions entering the decade. The emergence of SARS-CoV-2 in late 2019 triggered an immediate global health crisis that would define the early years of the 2020s.
The 2020s decade began on 1 January 2020 and encompasses the COVID-19 pandemic and its economic aftermath, the rise of generative artificial intelligence, escalating military conflicts including the Russian invasion of Ukraine and the Gaza War, growing populist movements, and mounting climate emergencies. India surpassed China as the world's most populous country in 2023.
The pandemic induced a global recession, supply chain disruptions, and a lasting shift toward remote work, e-commerce, and digital services. Generative AI reshaped labour and creative industries, while military conflicts in Europe and the Middle East redefined international security. Climate pressures prompted world leaders to designate the 2020s the 'decisive decade' for climate action.
