Climate change poses serious threats to human health, from extreme weather to disease spread. Vulnerable groups like the elderly and low-income communities face higher risks. Public health interventions, like early warning systems and heat action plans, aim to reduce impacts.
Global warming, driven by greenhouse gas emissions, creates dangerous feedback loops and tipping points. Rising temperatures lead to sea level rise, extreme weather, and ecosystem disruption. Adaptation strategies in urban planning, agriculture, and ecosystem management are crucial for building resilience.
