What is Chronic Climate Risk?

Chronic climate risks refer to the long-term and gradual impacts of climate change on various sectors. Unlike acute climate risks, which involve immediate and short-term events, chronic climate risks develop over an extended period, often spanning years or even decades. These risks arise from the underlying changes in climate patterns, atmospheric conditions, and environmental factors caused by climate change.

Chronic climate risks can manifest in many different ways and impact multiple aspects of our society, economy, and environment. Some examples of chronic climate risks include:

  1. Sea-Level Rise: The gradual rise in sea levels due to our changing climate poses risks to many coastal areas around the globe, leading to increased coastal erosion, saltwater intrusion into freshwater resources, and the potential for flood inundation of low-lying coastal regions.
  2. Changing Precipitation Patterns: Synoptic weather changes over time can alter rainfall patterns, resulting in long-term droughts in certain regions and increased precipitation and flooding in other regions. These shifts can impact agriculture, ecosystems, and water-dependent industries.
  3. Temperature Changes: Rising average temperatures can have long-term consequences for ecosystems, agriculture, and human health. Warmer daytime and overnight temperatures can lead to shifts in growing seasons, changes in species distributions, increased heat stress on humanity and animals, and altered energy demands.
  4. Impacts on Agriculture and Food Security: Chronic climate risks can affect agricultural productivity through changes in temperature, precipitation patterns, and the prevalence of pests and diseases. In some regions, crop types will need to change to accommodate the new climate normals. These impacts can jeopardize food security, especially in vulnerable regions.
  5. Health Risks: Climate change can worsen health risks, including the spread of certain diseases, increased heat-related illnesses, reduced air quality, and impacts on mental health due to displacement and stress associated with climate-related events.

Addressing chronic climate risks requires a comprehensive approach that includes mitigation and adaptation strategies. Mitigation efforts aim to reduce greenhouse gas emissions and slow down the pace of a changing change, while adaptation involves implementing measures to build resilience and sustainability to cope with the changing climate. These efforts involve the implementation of new policies, sustainable land use practices, resilient infrastructure development, improved water management, conservation of biodiversity, and the building of vulnerable communities.

Understanding and managing chronic climate risks is crucial for ensuring the well-being of present and future generations.
