I have chosen global warming, which relates most to global goal 13, climate action. Because although we have know about the problem for a long time and many things have been done to address the issues there does not seem to be any noticeable improvement.
It is believed the main causes of global warming and gradual increase the earth's temperature is caused by human activity. This includes the increase of carbon dioxide and other greenhouse gases from the burning of fossil fuels, intensive agriculture and land clearance. The greenhouses gases collect on the atmosphere around the earth and act as insulation trapping in the heat. This has increased more rapidly over the last 50 years in both developed countries and emerging markets, which have developed due to demands from higher living standards globalisation.

The main signs of global warming are; the rise of sea levels caused by melting ice caps and glaciers and the gasses in the sea water. Sea levels have risen by over 17 cm in the last century. The rise in the ocean's temperature, the hotter atmosphere around the earth has been absorbed by the seas and the temperature has slowly risen since 1969. The shrinking of the ice caps and glaciers, a study in Greenland has shown a loss of ice by 36 to 60 cubic miles of ice every year from 2000 to 2006.

Many efforts have been made to reduce the levels of greenhouse gasses particularly in developed economies. Many countries have put restrictions on emissions produced by industry particularly power generators. This has also been the case in individual lives; the significant growth in fuel efficient and electric cars, a ban on aerosol sprays, the use of efficient light bulbs, switching off lights and electrical appliances, increased recycling and efforts to plant more trees especially where they are being cut down.

At school we have motion sensor timers, meaning that when there is no movement the lights turn off, this saves energy. Another solution would be to add more accessible bicycle racks, this would increase the amount of pupils cycling rather than taking the car or public transport as this emits CO2. Solar panels and rain water collection areas would also benefit the school and reduce global warming. The left over food could be composted or even stored to produce methane gas. Limitations to these solutions would be: cost, space and time.

Despite these efforts the problem seems to be getting worse. I believe this is because of the inconsistent implementation between countries.
In summary, climate change needs to be tackled locally at school as well as internationally. From this project I have learned that this is not something we can wait for other people to solve, it will affect all future generations. Governments need to help developing countries to reduce emissions as well as improving their own carbon output. We can influence government behaviour by protesting and communicating with our own politicians so they know we feel it is important. I would work with my class and the school to decide if more can be done to in our community. Using less energy around the school use more alternative energy, such as solar. Encourage students to cycle to school and find ways to recycle more and waste less food.
