Description:

What is Climate Change

Climate change refers to long-term shifts in global temperatures and weather patterns caused primarily by human activities since the Industrial Revolution. While climate variations are natural, scientific evidence overwhelmingly shows that current warming is driven by increased greenhouse gas emissions from burning fossil fuels, deforestation, and industrial processes.

The Science Behind It

Greenhouse Effect: Carbon dioxide, methane, and other greenhouse gases trap heat in Earth's atmosphere, causing global temperatures to rise. Since 1880, Earth's average temperature has increased by approximately 1.1 degrees Celsius (2 degrees Fahrenheit), with the most rapid warming occurring in recent decades.

Current and Future Impacts

Global Environmental Effects:

1 billion people to face water scarcity by 2050
$43 trillion in stranded fossil fuel assets
1 million species at risk of extinction
Extreme weather events increased 5x since 1970s

India's Climate Challenges:

Heat waves: 25,000+ deaths since 1992, temperatures reaching 50 degrees Celsius
Water stress: 21 cities including Delhi, Chennai facing groundwater depletion
Agricultural impact: 7% decline in crop yields per 1 degree Celsius warming
Air pollution: 1.67 million deaths annually, economic cost $95 billion
Glacier retreat: Himalayan glaciers lost 40% ice since 1970s
Cyclone intensity increased 26% in Bay of Bengal (1982-2019)

Solutions and Actions

Global Response & Targets:

Paris Agreement: Limit warming to 1.5 degrees Celsius, requires 45% emission cuts by 2030
Renewable energy: $1.8 trillion invested globally in 2023
Carbon pricing: 46 national and 36 subnational systems covering 23% of emissions

India's Climate Actions:

Renewable capacity: >200 GW installed (target: 500 GW by 2030)
Solar tariffs dropped 85% since 2010
Forest cover: Increased by 2,261 km² (2019-2021)
National commitments: Net-zero by 2070, reduce emission intensity by 45% by 2030

What You Can Do:

Energy: Use energy-efficient appliances, switch to renewable energy providers
Transportation: Walk, bike, use public transit, consider electric vehicles
Consumption: Reduce, reuse, recycle; choose sustainable products
Diet: Eat less meat, reduce food waste, buy local when possible
Advocacy: Vote for climate-conscious leaders, support green policies
Education: Stay informed and share knowledge with others
