Climate change

Definition

Climate change refers to long-term alterations in temperature, precipitation, wind patterns, and other aspects of the Earth's climate system. These changes are driven by both natural processes and human activities, particularly the emission of greenhouse gases.

5 Must Know Facts For Your Next Test

1. Climate change is a major driver of biodiversity loss, as it alters habitats and ecosystems faster than many species can adapt.
2. The primary human-induced causes of climate change include deforestation, fossil fuel combustion, and industrial activities that increase greenhouse gas concentrations.
3. Rising global temperatures can lead to more frequent and severe weather events such as hurricanes, droughts, and heatwaves.
4. Ocean acidification, a result of increased CO2 absorption by seawater, negatively impacts marine life including coral reefs and shellfish.
5. Mitigation strategies for climate change include reducing carbon emissions through renewable energy sources and enhancing carbon sinks like forests.
