**Climate change is a complex phenomenon influenced by various factors. Let's break down each option:- **A. Rising temperatures and melting ice caps:** These are consequences of climate change rather than causes.- **B. Deforestation and burning fossil fuels:** Both activities increase greenhouse gas emissions, which contribute to climate change.- **C. Extreme weather events and disruptions to ecosystems:** These are also consequences of climate change.- **D. Greenhouse effect and global warming:** The greenhouse effect is a natural process that traps heat in the atmosphere, and global warming refers to the long-term rise in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.- **E. Renewable energy sources and sustainable practices:** These are solutions to mitigate climate change, not causes.**
