Climate Change

Definition

Climate change refers to long-term shifts in global or regional climate patterns, primarily driven by human activities that release greenhouse gases into the atmosphere, trapping heat and altering the Earth's temperature and weather patterns over an extended period of time.

5 Must Know Facts For Your Next Test

1. Climate change is causing more frequent and intense extreme weather events, such as heatwaves, droughts, wildfires, and hurricanes.
2. Rising global temperatures are leading to the melting of glaciers and ice caps, contributing to sea level rise and the displacement of coastal communities.
3. Climate change is having a significant impact on ecosystems, causing species extinction and disrupting the balance of natural habitats.
4. Developing countries are disproportionately affected by the consequences of climate change, as they often lack the resources to adapt and mitigate its effects.
5. Transitioning to renewable energy sources and implementing sustainable practices are crucial for reducing greenhouse gas emissions and mitigating the impacts of climate change.
