Climate Change

1. Global Temperature Rise

Earth's average temperature has risen by 1.2°C since pre-industrial times. Without drastic emissions reductions, we face 2-4°C warming by 2100, triggering irreversible tipping points like permafrost thaw and rainforest dieback.

2. Extreme Weather Events

Hurricanes, wildfires, floods, and droughts are becoming more frequent and intense. These events destroy infrastructure, displace millions, and disrupt food production. The 2021 Pacific Northwest heatwave and 2022 Pakistan floods demonstrate our vulnerability.

3. Sea-Level Rise & Coastal Flooding

Melting ice sheets and thermal expansion threaten coastal megacities like Miami, Shanghai, and Mumbai. By 2100, sea levels could rise 1-2 meters, displacing 200+ million people and causing trillions in economic losses.

4. Food & Water Security

Changing precipitation patterns and extreme heat reduce crop yields. Major breadbasket regions face simultaneous harvest failures. Water scarcity already affects billions, and glacier loss threatens drinking water for 2 billion people.
