Question

Why is global warming a matter of deep concern?

Answer 1

Global warming is a matter of deep concern because rising greenhouse gases are already shifting the climate in ways that threaten human well‑being, ecosystems and the economy: as temperatures climb, polar ice and mountain glaciers melt and sea levels rise, putting coastlines and low‑lying cities at risk of flooding and displacement; ocean warming and acidification damage coral reefs and fisheries that millions rely on; altered precipitation patterns and more intense heat waves, droughts and wildfires reduce crop yields and fresh water availability while increasing heat‑related illness and the spread of climate‑sensitive diseases; and many species and habitats cannot migrate or adapt fast enough, risking large‑scale biodiversity loss and long‑term changes to ecosystems that sustain food, water and storm protection all of which produce cascading social and economic harms and create urgent, potentially irreversible risks if emissions are not curtailed.
