Question

Define global warming, and differentiate it clearly from climate change. Explain the key natural and human-induced causes of global warming and briefly discuss which factors are currently dominant in driving global temperature rise.

Ghissu Editorial · Accepted Answer

Global warming is the long-term rise in Earth's average surface temperature from greenhouse gases, while climate change is the broader shift in rainfall, storms and sea levels that includes it. Natural factors like volcanoes and El Nino cause short-term swings, but human emissions, chiefly CO2, dominate today.

**Introduction**

Global warming, the rise in Earth's average temperature due to greenhouse gases, differs from climate change, which includes broader climatic shifts affecting weather patterns and ecosystems.

**Defining and Differentiating**

SKETCH: comparison | Global Warming vs Climate Change  
a: Global Warming  
b: Climate Change  
- Temperature increase :: Long-term shifts in weather patterns  
- Primarily caused by GHGs :: Caused by both natural and anthropogenic factors  
- Focus on atmospheric warming :: Includes changes in precipitation, storms, and sea levels  
- A subset of climate change :: Encompasses global warming and its broader effects

1. **Global Warming Explained**: It refers to the long-term increase in surface temperature caused by GHGs such as CO₂, methane, and nitrous oxide; ==Mauna Loa Observatory== data shows CO₂ levels rising from 280 ppm pre-Industrial Revolution to over 400 ppm today, correlating with a ~1.1°C rise over pre-industrial levels.

2. **Climate Change Scope**: Climate change encompasses global warming plus changes in precipitation, storms, and sea levels; ==Andhra Pradesh== experiences erratic monsoons and increased cyclones as part of this broader phenomenon.

**Causes of Global Warming**

3. **Natural Causes**: Volcanic eruptions, solar variations, and oceanic cycles like El Niño cause short-term temperature fluctuations but cannot explain sustained warming.

4. **Human-Induced Causes**: Fossil fuel combustion, deforestation, and industrial emissions, notably in ==Visakhapatnam and other Andhra Pradesh industrial hubs==, are the main drivers; deforestation reduces carbon sinks, worsening warming.

5. **Dominant Drivers**: IPCC confirms human GHG emissions, especially CO₂ from energy and land-use changes, dominate current warming trends.

**Way Forward**

6. **Renewable Energy and Afforestation**: Scaling solar and wind energy per the National Action Plan on Climate Change⟦1⟧ and promoting afforestation in ==Andhra Pradesh== can mitigate emissions.

7. **Climate-Resilient Agriculture**: Developing drought-resistant crops for ==Rayalaseema== and enhancing early warning systems for heatwaves and cyclones are crucial.

**Conclusion**

Understanding global warming’s causes and its distinction from climate change is essential for targeted climate action, particularly in vulnerable states like ==Andhra Pradesh==.
