Climate change

• Ozone depletion


  The gradual thinning of Earth’s ozone layer in the upper atmosphere caused by releasing chemical compounds containing gaseous chlorine or bromine from industry and other human activities.
• Greenhouse effect


  process that occurs when gases in Earth’s atmosphere trap the sun’s heat. This process makes Earth much warmer than it would be without an atmosphere.
• Global warming


  It refers to the planet's long-term warming since the early 20th century and most notably since late 1970s due to increase in fossil fuel emissions since the industrial revolution.
• Climate change


  The catch-all term for the shift in worldwide weather phenomena associated with an increase in global average temperatures.
• Human-based causes of climate change

  Production patterns and consumption patterns
• Production patterns


  The production of goods and services. These are the activities that companies and factories do so that they can give us consumables.
• Consumption patterns


  Activities that people has to do with their consumption of goods.
• examples of production patterns that contribute to climate change

  Industrialization, deforestation, agriculture
• Examples of consumption patterns that contribute to climate change

  Waste disposal, overconsumption
• Flooding


  Sea-level rise increases base levels for coastal river reaches. Higher ocean water and air temperatures increase the possibility for evaporation and therefore cloud formation and more rain.
• Air pollution


  When the earth’s temperature rises, not only does our air get dirtier—with smog and soot levels going up—but there are also more allergenic air pollutants.
• Extreme weather


  Climate change is also considered a key factor in increasing the risk and extent of wildfires in various parts of the world.
• Mass migration


  People are being forced to leave their homes because of drought, flooding, and other climate-related disasters.
• Effects of climate change

  Flooding, air pollution, extreme weather, health risks, mass migration
• Mitigation for Climate Change

  Sustainability, Paris Agreement, Laudato Si, Renewable energy, energy and water efficiency, sustainable transportation, sustainable infrastructure, responsible consumption or recycling
• Other signs of climate change

  1. Global temperature rise
  2. Warming oceans
  3. Shrinking ice sheets
  4. Glacial retreat
  5. Sea level rise
  6. Extreme weather
