TEDx Talks - How do we climb out of crisis? Learn from snow and catastrophe | Ulyana Horodyskyj Peña | TEDxBoston
The speaker shares a personal story of how a childhood experience with snow sparked a lifelong interest in ice and its impact on the planet. They highlight the significance of glaciers as indicators of climate change, noting that ice holds historical data about Earth's climate and human impact. The rapid melting of ice, particularly in Greenland and Antarctica, is causing significant sea level rise and affecting global weather patterns. The speaker stresses the importance of understanding and protecting ice to mitigate these effects.
Practical solutions are discussed, such as using geotextiles to slow glacial melting and implementing strict air quality regulations to reduce black carbon emissions. The speaker encourages participatory science, where individuals can contribute to climate data collection, helping scientists track changes in real time. They emphasize that reducing black carbon emissions can lead to rapid cooling benefits and that collective action is crucial to addressing the climate crisis. The talk concludes with a call to action for individuals to engage in community science and support cleaner energy practices.
Key Points:
- Ice is crucial for regulating global climate and holds historical climate data.
- Rapid ice melting is causing sea level rise and affecting weather patterns.
- Reducing black carbon emissions can quickly benefit the climate.
- Participatory science allows individuals to contribute to climate data collection.
- Collective action and cleaner energy practices are essential to address climate change.

1. 🏔️ Childhood Avalanche Adventure
- A childhood snowball fight at 10,000 ft in the Swiss Alps led to an unforgettable experience when an avalanche was triggered, providing a lasting impression of the power of nature.
- The event occurred during the summer, highlighting the unexpected nature of snow in that season, and left a strong emotional impact on the individual, influencing their perception of natural forces.
2. 🌍 Discovering the Significance of Ice
- Ice glaciers are not just frozen water; they serve as layered timelines that document Earth's history, including changes in temperatures, sea levels, and biodiversity.
- Recent studies show that ice layers reveal human impact, such as pollution, indicating that understanding ice is crucial for survival.
- Working on an icebreaker ship in Antarctica revealed the deeper significance of ice, highlighting its role in environmental history and future predictions.

5. 🗻 Global Ice Loss Observations
- Ice is vanishing at an accelerating and perilous pace across various regions, including the Himalayas, the Arctic, and the Antarctic.
- In the Himalaya region, particularly near Mount Everest, there has been a significant ice loss of 95 meters over 87 years, which is comparable to the height of the Statue of Liberty.
- This ice loss is observed even near the summit of Mount Everest, at altitudes where jetliners fly, indicating a widespread and concerning trend.
- Such ice loss has implications for local communities, including changes in water supply, increased risk of glacial lake outburst floods, and impacts on ecosystems.
- In other regions like the Arctic and Antarctic, ice loss contributes to rising sea levels, which can lead to coastal erosion and threaten coastal communities globally.

6.2. Dynamics of Ice Shelves and Sea Level Rise
7. 📉 Visualizing Ice Melt Impact
- Sea ice melts and refreezes annually without changing water levels, while land-based ice melt contributes to sea level rise.
- Complete melting of Greenland's ice would result in approximately 23 feet of global sea level rise.
- Complete melting of Antarctica's ice would contribute an additional 200 feet to global sea levels.
- Since 1880, global sea levels have risen by an average of 8 inches.
- By 2050, a further increase of one foot in sea level is predicted, potentially displacing millions in coastal cities.
- Local effects of sea level rise are evident in coastal flooding and erosion, impacting communities.

9. 🧊 Innovations in Glacial Preservation
- Scientists in Switzerland have successfully used geotextiles to cover parts of glaciers, which reflect sunlight and reduce melting rates.
- Black carbon emissions have a significant warming impact, surpassing carbon dioxide, as they absorb sunlight effectively and can travel long distances to affect polar regions.
- Despite regulations in the EU and the US to curb black carbon emissions, these emissions are rising globally, especially in regions with lax regulations.
- Reducing black carbon emissions can lead to quick climate cooling benefits, but it requires more funding, skilled glaciologists, engineers, and public engagement.
- Participatory science initiatives involve students, teachers, and the public in climate data collection, helping scientists monitor changes in real-time effectively.
- Snow and ice act as natural archives, capturing air particles like black carbon, which helps in identifying pollution levels and targeting emission sources.
- Transitioning to cleaner energy sources and minimizing open agricultural burning can significantly reduce both black carbon and carbon dioxide emissions.
- Tracking black carbon is essential for mapping pollution spread, identifying hotspots, and enforcing stricter pollution policies, benefiting both air quality and polar health.
