The effects of climate change encompass the biophysical and socio-environmental consequences arising from long-term shifts in climate variables driven primarily by anthropogenic greenhouse gas emissions. Key effects include increased global mean surface and ocean temperatures, altered precipitation patterns, sea-level rise via thermal expansion and cryosphere melt, and increased frequency and intensity of heatwaves, droughts, extreme precipitation events, and some categories of tropical cyclones. These changes cascade into impacts on hydrological regimes, ecosystem structure and function, species distributions, biogeochemical cycles, agricultural productivity, human health, and infrastructure, often interacting nonlinearly and amplifying existing environmental and socioeconomic vulnerabilities.
Glaciers ending in lakes, oceans or ice shelves make up 3.2% of the world's glaciers, but lost 134 billion metric tons (148 billion tons) of ice each year between 2000 and 2019, accounting for more than half of all glacier ...
