Climate Change in Brief by Devashish Negi

- 2. What Is Climate Change? Long-term shifts in temperatures and weather patterns. Human activities, especially the burning of fossil fuels, are the main contributors. Greenhouse gases trap heat, raising temperatures and causing climate change. 2
- 3. Greenhouse Gases • Main contributors: carbon dioxide and methane. • Sources include burning fossil fuels, deforestation, and industrial processes. • Major sectors responsible: energy, industry, transport, buildings, agriculture, and land use. 3
- 4. Human Impact on Global Warming • Humans responsible for virtually all global heating over the last 200 years. • Current Earth surface temperature is 1.1°C warmer than the late 1800s. • Last decade (2011-2020) was the warmest on record. 4
- 5. Consequences of Climate Change • Beyond temperature rise: droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, storms, and declining biodiversity. • Impacts on health, food production, housing, safety, and employment. 5

- 7. Diverse Impact on People • Vulnerable groups include those in small island nations and developing countries. • Rising sea levels and protracted droughts force communities to relocate. • Future projections indicate an increase in weather-related displacement. 7
- 8. Global Warming Limit • UN reports emphasize limiting global temperature rise to 1.5°C. • Current policies point to a potential 3°C rise by the end of the century. • Seven largest emitters contribute about half of global greenhouse gas emissions. 8
- 9. Shared Responsibility • Climate change affects everyone, but some countries produce more emissions. • Emphasis on collective action, with greater responsibility on high- emission countries 9
- 10. The Challenge and Solutions • Climate solutions offer economic benefits and environmental protection. • Global frameworks like Sustainable Development Goals, UN Framework Convention on Climate Change, and the Paris Agreement guide progress. • Three categories of action: cutting emissions, adapting to impacts, and financing adjustments. 10
- 11. Cutting Emissions • Transition from fossil fuels to renewables (solar, wind). • Urgent action needed: emissions must be halved by 2030 to limit warming below 1.5°C. • Drastic reduction in coal, oil, and gas usage required. 11
- 12. Adapting to Climate Consequences • Protection of people, homes, businesses, livelihoods, and ecosystems. • Priority for vulnerable populations with limited resources. • High returns on investment, e.g., early warning systems save lives and property. 12
- 13. The Cost of Inaction • Climate action requires significant financial investments. • Inaction is more expensive. • Industrialized countries urged to fulfil $100 billion annual commitment to support developing countries. 13
- 14. Conclusion and Call to Action • We face a significant challenge, but solutions exist. • Urgent global action needed to mitigate and adapt to climate change. • Collective efforts will shape a sustainable and resilient future. 14
