TED-Ed: 1816: The year with no summer | David Biello

The video discusses the 1815 eruption of Mount Tambora and its global climatic impact, known as the Year Without Summer. It explores geoengineering as a potential solution to climate change, focusing on solar radiation management. While these methods could cool the planet, they pose significant risks and uncertainties. Current research includes small-scale experiments, but the primary focus remains on reducing emissions and removing CO2. Geoengineering might be a last resort, but it requires careful consideration due to its potential for unintended consequences.

What was the significant global impact of the Mount Tambora eruption?

• It caused a massive earthquake.

• It led to 'The Year Without Summer'.

• It resulted in a new island formation.

• It increased global temperatures.

What is the primary goal of solar radiation management in geoengineering?

• To reduce volcanic eruptions.

• To enhance marine biodiversity.

• To block sunlight and cool the planet.

• To increase agricultural productivity.

Which natural event is often cited as evidence that solar radiation management might work?

• The eruption of Mount St. Helens.

• The eruption of Mount Tambora.

• The eruption of Mount Vesuvius.

• The eruption of Mount Fuji.

What is a major risk associated with solar radiation management?

• It might enhance greenhouse gas emissions.

• It could result in permanent cooling.

• It might cause unpredictable climate effects.

• It could lead to increased volcanic activity.

Why is it challenging to predict the outcomes of solar radiation management?

• Because it requires advanced technology.

• Because the Earth is a chaotic system.

• Because it depends on volcanic activity.

• Because it has never been attempted before.

Why might geoengineering be considered a last resort for civilization?

• Because it is easy to implement.

• Because it is a natural process.

• Because it can be done without approval.

• Because it might be necessary in desperate times.

What is a potential danger of a rogue actor implementing geoengineering?

• It might reduce fossil fuel usage.

• It might cause unintended climate changes.

• It could lead to global cooperation.

• It could enhance global warming.
