Climate change

• Human causes of climate change

  80% of worlds energy comes from fossil fuels
• Human causes of climate change

  Increased car owner ship -

  increased carbon dioxide emissions and car ownership predicted to increase by 60% by 2070
• Deforestation especially Amazon rainforest-

  less carbon dioxide being absorbed by trees
• human causes of climate change

  Methane- released from landfill sites- increase in paddy fields increased Methane and increased demand in beef from belching cattle, methane can result in 80% in more heating than Carbon dioxide but only stays in the atmosphere For around 12 years WHERES co2 can stay there for up to 200 years
• Human causes of climate change

  Car exhausts - nitros oxide Can result In 200 more years of heating by 2040 and can stay in the atmosphere for over a century
• local impacts of climate change

  as summer temps tired may increase droughts will become more frequent and dangerous - summer temperatures could increase to 1-3 degrees which could result in a number of heat related deaths especially amongst young children and older people
• Altered rainfall patterns could bring more heavy downfalls and flood risks - 25 to 40% increase in the west of scotland which could impact on housing businesses and infrastructure, warmer wetter weather conditions could increase with rot especially in older houses and spreading disease
• Sea level rise- increased coastal flooding erosion and retreats - a rise of over 4cm in the next 50 years abandoning low lying land and more refular damage to coastal roads
• Loss of species, existing pest and disease to be established in scotland, especially low lying coastal areas
• Soils may be altered by changes to rainfall patterns and weather increases reducing their ability to support agriculture and forrestry. However, a warming climate has the chance to improve growing plants in scotland and improve our productivity of agriculture and forestry with double drops with some fruits. plant growth needs tempatures of 6 degrees above
