Climate change - AQAManaging the impacts of climate change

Evidence has shown that Earth鈥檚 temperature is rising due to an increase in greenhouse gases. This has created and will continue to create, a number of negative effects.

Managing the impacts of climate change

Mitigation strategies

means to reduce or prevent the effects of something from happening. Mitigation strategies include:

  • Alternative energy - using alternative energy such as solar, wind or tidal can reduce the use of fossil fuels. This will reduce the amount of carbon dioxide released into the atmosphere.
  • Carbon capture - this is the removal of carbon dioxide from waste gases from power stations and then storing it in old oil and gas fields or coal mines underground. This reduces the amount of emissions into the atmosphere.
  • Planting trees - encouraging , means that there will be more trees to absorb the carbon dioxide in the atmosphere during the process of photosynthesis.
  • International agreements - in 2005 the Kyoto Protocol became international law. The countries that signed up to the treaty pledged to reduce their greenhouse gas emissions. In 2016, the Paris Agreement united all the world's nations in a single agreement on tackling climate change. The agreement aims to limit global warming to well below 2掳C, ideally no more than 1.5掳C. Each year the United Nations holds a meeting to discuss climate change. This meeting is called the Conference of the Parties, or COP. The UK hosted the 26th Conference of the Parties (COP26) in Glasgow between the 31st of October and the 12th November 2021. At the end of each COP, every country promises to take action to reduce carbon emissions.

Adaptation strategies

Adaptation strategies do not aim to reduce or stop global warming. Instead they aim to respond to climate change by limiting its negative effects. Strategies include:

  • Agriculture - farmers will have to adapt as some crops may not be able to grow in a warmer climate. However, other crops (eg oranges and grapes) will be able to be planted.
  • Water supply - water transfer schemes could be used. This is where water is transferred from an area of water surplus to an area of water shortage.
  • Reducing risk from sea level rise - areas at risk from sea level rise may use sea defences to protect the land from being eroded away.
