Syllabus: GS3/Environment Degradation; Disaster Management

Context

  • Global warming is raising sea levels and making flooding more common in some areas.
    • Researchers have held them responsible for discouraging the growth of plants of many tree species in coastal areas.

About

  • The study paper has reported that a rising sea and coastal flooding could actually enhance the resilience of some coastal tree species while being detrimental to others.
  • One species in particular, the American holly (Ilex opaca), responded by increasing the rate at which it grew — while loblolly pine (Pinus taeda) and pitch pine (Pinus rigida) trees suffered under higher water levels.
  • Cause: The tree rings consist of water vessels. When a tree is exposed to a lot of rain along with appropriate levels of sunlight and ambient temperature, it also develops more water vessels. 
  • But a heavy downpour and a deluge would disrupt this process altogether and prevent the plant from growing normally. 

Sea-level Rise Accelerating

  • Sea levels were increasing by around 2 mm/year in 1993.
    • This rate has since doubled and climate researchers expect floods in coastal areas will increase threefold by 2050.
  • Reason:Climate change brought on by fossil-fuel burning and greenhouse gas emissions has led to a steady increase in global temperatures.
    • As a result, sea surface temperatures and glacier melting have increased, eventually rising sea levels and posing a major threat to coastal cities worldwide, including Indian coastal cities.
Climate Change
– Climate change refers to long-term shifts in global or regional climate patterns. 
– It’s primarily driven by human activities, such as burning fossil fuels, deforestation, and industrial processes, which release greenhouse gases like carbon dioxide (CO2) and methane into the atmosphere. 
– These gases trap heat, causing the Earth’s temperature to rise—a phenomenon known as global warming.
– Impact: It threatens the essential ingredients of good health – clean air, safe drinking water, nutritious food supply and safe shelter – and has the potential to undermine decades of progress in global health.

Concerns with Increase in Sea Level

  • Flooding: It leads to more frequent and severe flooding in coastal areas, threatening infrastructure, homes, and livelihoods.
  • Displacement: Rising seas force communities to relocate, leading to displacement and potential conflicts over resources.
  • Saltwater Intrusion: Salinity contaminate freshwater sources, affecting drinking water supplies and agriculture.
  • Economic Impact: Coastal industries, such as fishing and tourism are severely impacted, leading to job losses and economic instability in affected regions.
  • Biodiversity Loss: Ecosystems like mangroves and coral reefs are threatened, impacting biodiversity and the services these ecosystems provide.
  • Health Risks: Flooding leads to the spread of waterborne diseases.
