when the redistribution system is disrupted, weather and climate patterns change. Long-term changes (climatic changes) happen from accumulations of short-term changes (weather changes).

    An international effort to form an agreement whereby all countries try to reduce their emission of greenhouse gases has so far not been achieved. An international organization called Inter-governmental Panel on Climate Change (IPCC) was formed to address this issue. It has held many conferences to work out a treaty among the nations of the world to reduce AGW and try to slow down the process of climate change. None of these have been successful. The IPCC 2015 Paris Summit came to an agreement to reduce greenhouse gas emissions in order to limit the rise in global average temperature to well below 2 degree C above pre-industrialisation level. On this agreement total 195 countries signed.

  • What is deforestation?

  • Does deforestation happen only in forest areas? How about in your local area, even if there are no forests?

  • How does deforestation affect global warming? (You will need to recall your study of photosynthesis in your science class.)

  • What are some other ways in which human action contributes to global warming?

 
      Broadly, the disagreements are between the 'developed' countries (mainly industrialised, economically more advanced countries of the West) and 'developing' countries (countries that are not as industrialised). Developed countries want developing countries to cut down on burning coal and other activities that add greenhouse gases to the atmosphere. Developing countries argue that developed countries developed precisely by burning fossil fuels when they were developing. Developing countries say that their economic development will be seriously damaged if they don't burn fossil fuels (mainly coal) , and that developed countries should do their fair share of work to help find alternatives that can help the developing countries to progress.

     Most scientists from around the world agree on this much: AGW is real, it is happening, and it is leading to rapid and drasric climate change. They warn that severe weather and other changes will increase in the coming years and threaten life as we know it.

      One of the human activities that contribute to global warming is deforestation. Discuss this with your teacher and your classmates and try to answer the questions given above in a few sentences.
