Q & A
  • What are some of the effects of climate change being seen in the European Alps?

    -The European Alps are experiencing increased melting of glaciers, more frequent devastating forest fires, prolonged droughts leading to water shortages, and increased landslides as permafrost thaws.

  • How has climate change impacted fisherman Leonid Nalotov in Siberia?

    -Leonid Nalotov made his living fishing in a 15 km long lake in Siberia. Due to rising temperatures melting permafrost, the natural dam separating the lake from a river broke, causing the lake to drain away completely and leaving Nalotov without his source of income.

  • What efforts are being made to remove CO2 from the atmosphere?

    -Companies like Climeworks in Switzerland are developing facilities to filter CO2 out of the air and liquefy it. In Norway, CO2 captured elsewhere in Europe will be transported via ships and pipelines and injected deep underground for storage.

  • How could reducing meat consumption help lower greenhouse gas emissions?

    -Food production accounts for 25% of greenhouse gas emissions. Reducing meat consumption to 300g per person per week, a quarter of current levels in Germany, would significantly reduce emissions from agriculture.

  • What is the goal of Nikita Zimov's 'Pleistocene Park' project?

    -Nikita Zimov aims to recreate a Pleistocene era ecosystem in Siberia, with large herds of grazing animals like bison, horses and reindeer. He hopes their trampling will compress snow cover and allow colder temperatures to penetrate the soil, preserving the permafrost.

  • How has climate change impacted Lake Chad in Africa?

    -Lake Chad covered 25,000 sq km in 1963 but shrank to just 2500 sq km by 2007, a loss of over 90% of its area, due to decreasing rainfall. This threatens the livelihoods of over 50 million people who depend on the lake.

  • What technologies are being developed to improve building energy efficiency?

    -Researchers are developing textile facades that provide shade and reduce cooling needs. Combining these fabrics with highly energy efficient windows and insulation can cut a building's energy use by 60-80%.

  • What is the goal of the SkySails project?

    -SkySails uses large kite-like gliders flying at high altitudes to generate electricity from strong steady winds not accessible at ground level. This provides a constant renewable energy source.

  • How much potential does Norway have for underground CO2 storage?

    -Experts estimate Norway's continental shelf could potentially absorb and safely store underground up to 80 gigatons of CO2, equal to all of Europe's emissions for the next 100 years.

  • What disaster struck the village of Bondo in Switzerland?

    -In 2017, over 3 million cubic meters of rock broke loose from the Piz Cengalo mountain, crashing down into Bondo in a landslide that left 8 dead and destroyed part of the village. It was attributed to permafrost thaw.
