Wildfires and Carbon Emissions

  • Increased temperatures and low moisture levels led to widespread wildfires in South America.
  • Argentina and Paraguay experienced a significant increase in wildfire hotspots, contributing to the highest carbon dioxide emissions from wildfires in the past 20 years.
  • In the Amazonas state of Brazil, emissions from wildfires during July to October reached a record high in the past two decades.

Flooding, Landslides, and Tropical Storms

  • The region witnessed extreme rainfall events leading to flooding and landslides.
  • Puerto Rico recorded its highest-ever daily rainfall, resulting in fatalities and significant damage.
  • The impact of tropical storms and hurricanes contributed to flooding and agricultural damage in various countries, including Cuba and Jamaica.

Glacier Melting and Sea Level Rise

  • Glaciers in the Andes mountain range showed a declining trend in ice mass due to increasing temperatures and decreasing snowfall.
  • In the tropical Andes, glaciers lost ice mass at a rate of -96 m water equivalent per year between 1990 and 2021.
  • Sea levels along the coasts of Latin America and the Caribbean rose at a rate higher than the global average, posing risks to coastal communities and ecosystems.

Economic Losses and Adaptation Challenges

  • The region experienced significant economic losses due to climate-related hazards, with storm- and flood-related events being the most common.
  • The impacts on agriculture, renewable energy production, and water resources affected the region's ability to mitigate and adapt to climate change.
  • Decreased river flows in Brazil led to a decline in hydroelectric power generation and increased reliance on fossil fuels.

Priorities for Adaptation and Mitigation

  • Key areas for climate change adaptation and mitigation in the region include agriculture, food security, and renewable energy.
  • Persistent droughts' impacts on agricultural production and the untapped potential of solar and wind resources are highlighted.
