Key insights

• ⚠️ Three degrees of global warming could have catastrophic effects: heatwaves, droughts, extreme precipitation, and rising sea levels.
• 🌍 Current warming levels have already led to climate migrants, moving to cities due to the impact on their homes.
• 🔥 Global temperatures have risen between 1.1 and 1.3 degrees Celsius since the industrial revolution, and drastic measures are needed to stop burning fossil fuels.
• ⏰ Yuri's projections show a 1 in 4 chance of hitting 3 degrees by the end of the century with current policies.
• 🌆 A rise of 3 degrees would have widespread consequences, affecting even wealthy cities and rich countries.
• 🌾 Climate change disproportionately affects small-scale farmers, leading to poverty, migration, and intensified natural disasters.
• 🌊 Rising sea levels due to climate change are affecting vulnerable coastal areas, threatening millions of inhabitants.
• 💧 High wet bulb temperatures can be deadly; 3-degree global warming could lead to dangerous wet bulb temperatures; increased migration to cities due to climate displacement; competition for resources will intensify.

Q&A

• How does climate change impact water resources and potential conflict?

  In a three-degree world, climate extremes could heighten concerns about water conflict, particularly in regions with competing claims over vital rivers. This, in turn, underscores the need for global efforts on mitigation and adaptation to avert the potential societal collapse and conflict.

• What are the potential consequences of dangerous wet bulb temperatures resulting from 3-degree global warming?

  High wet bulb temperatures, which can be deadly for the human body, are a concern in a 3-degree global warming scenario. It could lead to increased migration to cities due to climate displacement and intensify competition for resources.

• How does climate change contribute to potential mass migration to urban areas?

  Climate change, including factors like rising sea levels, severe storms, and floods, can lead to potential mass migration from affected rural areas to urban areas, where people may seek refuge from climate-related challenges.

• What are the impacts of rising sea levels on coastal areas?

  Rising sea levels due to climate change pose a significant threat to coastal areas, potentially displacing millions of inhabitants. Low-lying coastal areas are particularly vulnerable, facing the risk of displacement and loss of land.

• How does climate change disproportionately affect small-scale farmers?

  Climate change disproportionately affects small-scale farmers, leading to poverty, migration, and intensified natural disasters. It can also result in decreased rainfall, further exacerbating challenges for farmers in vulnerable regions.

• What are the chances of reaching 3 degrees of global warming by the end of the century under current policies?

  Yuri's projections show a 1 in 4 chance of hitting 3 degrees by the end of the century with current policies. Keeping all policy promises could result in a best estimate of 2 degrees, but there's still a 1 in 20 chance of reaching 3 degrees.

• What is the current rise in global temperatures since the industrial revolution?

  Global temperatures have risen between 1.1 and 1.3 degrees Celsius since the industrial revolution, emphasizing the urgent need for drastic measures to reduce fossil fuel emissions and curb further global warming.

• What are some of the catastrophic effects of a 3-degree global warming?

  Three degrees of global warming could have catastrophic effects, including heatwaves, droughts, extreme precipitation, and rising sea levels. It could lead to significant impacts on cities and countries, affecting both wealthy and vulnerable areas.

• 00:02 Three degrees of global warming could lead to catastrophic heatwaves, droughts, extreme precipitation, and rising sea levels. Current warming levels have already resulted in climate migrants, such as Minara, moving to cities due to the impact on their homes.
• 03:16 Yuri's projections show a 1 in 4 chance of hitting 3 degrees by the end of the century with current policies. Keeping all policy promises could result in a best estimate of 2 degrees, but there's still a 1 in 20 chance of reaching 3 degrees. A rise of 3 degrees would have widespread consequences, affecting even wealthy cities and rich countries.
• 05:20 Climate change disproportionately affects small-scale farmers, leading to poverty, migration, and intensified natural disasters. Coastal areas face rising sea levels, threatening millions of inhabitants.
• 08:57 Rising sea levels due to climate change are affecting the village of Togoru in Fiji, causing displacement and loss of ancestral land. Storms and floods are becoming more severe, leading to potential mass migration to urban areas. Additionally, increasing temperatures are creating life-threatening conditions in densely populated cities.
• 11:41 High wet bulb temperatures can be deadly; 3-degree global warming could lead to dangerous wet bulb temperatures; increased migration to cities due to climate displacement; competition for resources will intensify.
• 13:53 China's claim to vital rivers sparks concerns of water conflict in a three-degree world due to climate extremes, societal collapse, and the need for global efforts on mitigation to avoid a three-degree world.
