CLIMATE CHANGE

• what is climate change

  a long-term shift in the planet's weather patterns and average temparatures

  
• evidence of climate change

  temperatures are increasing

  ice and glaciers melting

  sea levels rising

  
• natural causes of climate change

  sunspots, eccentricity, obliquity, precession, volcanoes erupting, asteroids

  
• how do volcanic eruptions cause temp change

  by reducing the incoming solar energy

  
• eccentricity

  stretch

  
• obliquity

  The tilt of the Earth's axis

  
• precession

  Wobble in Earth's rotational axis

  
• human causes of climate change

  Fossil fuels, agriculture, deforestation, carbon emissions, eating beef (farts release methane)

  
• what are the causes of deforestation

  paper, furnature, paster for cows, palm oil

  
• what is the enhanced greenhouse effect

  The enhanced greenhouse effect, sometimes referred to as climate change or global warming, is the impact on the climate from the additional heat retained due to the increased amounts of carbon dioxide and other greenhouse gases that humans have released into the earths atmosphere since the industrial revolution.

  
• green house gases

  a gas that contributes to the greenhouse effect by absorbing infrared radiation
• examples of green house gases

  methane

  Carbon dioxide

  nitrous oxide

  ozone

  sulfur dioxide

  carbon monoxide

  
• reasons why sea-levels are rising


  Ice blocks are melting

  thermal expansion
• what is thermal expansion


  the expanding of matter when it is heated

  
• examples of fossil fuels


  coal, oil, natural gas

  
• tipping point


  the point at which the impact of climate change on the planet will become irreversible

  
  

  point of no return
• consequences of Climate change

  Coral bleaching - great barrier reef, ecosystem destroyed, leads to declining in tourism

  
  

  famine - niger, malnourished, poor jobs, not at school, poverty cycle

  
  

  ice melting - antarctica, ecosystem collapse, thermal expansion, sea level rise

  
  

  flooding - bangladesh, thermal expansion, sea level rise, land/houses lost, prevents travel climate refugees

  
  

  drought - sahel, no food, water, crops, people dying

  
  

  forest fires - austrailia, houses burnt, wildlife + ecosystem collapse, habitat loss

  
  

  heatwave - hard to survive, heart attacks, fainting, austrailia, food chain, ecosystem affected, collapsed

  
  

  disease - nigeria, hospital pressure cost, malaria, disease, mosquitos, heat survive

  
• consequences in the tropics


  forest fires

  famine

  disease

  coral bleaching
• consequences in the polar regions

  ice melt-habitat

  methane release

  ice melt-sea level rise
• wildlife consequences

  polar bears are getting affected because ice is melting destroy their homes.

  
  

  Making these animals forced out of their suitable habitats in search of food and water killing most of these animals on the journey.

  
• Ocean acidification + temperature


  -Temperature affects living things making them evacuate and die

  - impacts ecosystem

  -CO2 levels rising

  -Water absorbs Co2

  - Adds more acidity

  -break down the shells of animals that live in the sea

  -can cause coral to grow more slowly and maybe even die
• what are ways of managing climate change

  adaption and mitigation
• adaption

  means anticipating the adverse effects of climate change and taking appropriate action to prevent or minimise the damage they can cause
• what are examples of adaption

  building houses on stilts to overcome the flooding associated with sea level rise

  
  

  grow drought resistant crops

  
  

  carbon capture and storage
• what is carbon capture and storage

  It is a way to collect CO2 from power stations before it is released into the atmosphere

  
• mitigation

  to reduce or prevent the effect of something from happening.
• examples of mitigation

  alternative - reduce fossil fuels being burnt

  
• what was the paris agreement


  aim of the paris agreement is to keep temperature increases to 1.5 degrees celcius more than idustrial era and certainly no more than 2 degrees celcius

  
  

  countries set targets to reduce greenhouse gases

  
  

  discuss and support (finance, tech to cope)

  
  

  first meeting of its kind
