30-Second Take
- Global warming threatens up to one-third of species by 2100
- Every half-degree temperature rise significantly increases extinction risk
- Current policies put Earth on track for 2.7°C warming by 2100
+ Dive Deeper
Quick Brief
Essential Context
Scientists warn that climate change could trigger Earth’s sixth mass extinction event. The survival of millions of species hinges on how much temperatures rise above pre-industrial levels.
Core Players
- IPCC – UN climate science authority
- IUCN – Global conservation organization
- World Wildlife Fund – Leading conservation group
Key Numbers
- 14% species extinction risk at 1.5°C warming
- 29% risk at 3°C warming
- 48% risk at 5°C warming
- 42,100 species currently endangered
Full Depth
The Catalyst
Recent IPCC reports reveal escalating species extinction risks as global temperatures rise. Even limiting warming to 1.5°C could threaten 14% of species.
Inside Forces
Temperature changes disrupt habitats, migration patterns, and food chains. Species unable to adapt face increased extinction risk.
Coral reefs, arctic wildlife, and mountain ecosystems face particular danger.
Power Dynamics
International climate agreements aim to limit warming to 1.5°C, but current policies track toward 2.7°C.
Major economies’ emission reduction commitments will determine species survival rates.
Outside Impact
Species loss threatens food security, medicine development, and ecosystem stability.
Economic costs could reach trillions as biodiversity decline affects agriculture and tourism.
Future Forces
Key factors shaping species survival:
- Global emission reduction efforts
- Habitat preservation initiatives
- Climate adaptation strategies
- International conservation cooperation
Data Points
- 75% decline in flying insect populations since 1990
- 30% freshwater species decline since 1990
- 26% vertebrate range loss at 3.2°C warming
- 16% species extinction risk by 2070 under moderate warming
The next decade’s climate actions will determine the fate of millions of species. Immediate emission reductions could prevent the worst extinction scenarios, while delayed action risks catastrophic biodiversity loss.
