A Message to World Leaders

Extreme Weather Featured Image 9


Hello, everyone. Today, I would like to share with you about what you, as world leaders, need to do about extreme weather.

Extreme weather is a weather event that is rare for the place where it occurs. Even though we are lucky that there is no snow or droughts in Hong Kong, we are experiencing the effects of global warming, which causes extreme weather. According to the Hong Kong Observatory, there was an average rise of 0.13°C per decade from 1885 to 2019 and the rate of increase in average temperature grew rapidly in the latter half of the 20th century. The average increasing rate was 0.21°C per decade during 1990-2019.

I think the increase in temperature in Hong Kong is partly caused by the over- consumption of air-conditioning. Most indoor facilities in Hong Kong are air-conditioned and I often find that these facilities are too cold. For example, people often need to put on a cardigan when they are in a restaurant or on a bus even during summertime. The more we use air-conditioning, the more electricity we consume. The more electricity we consume, the hotter it becomes. This is because the carbon emissions from the burning of coal for production of electricity will make the weather way hotter.

To combat extreme weather, I think we should use less air-conditioning. During winter, the indoor facilities should turn off the air-conditioners and open the windows to allow for the circulation of fresh air. During summer, we should set the temperature of air-conditioners to 25.5°C instead of 15°C to stop the indoors from feeling like a freezer. Furthermore, world leaders should make use of both preventative and reactive actions as a response to combat climate change. Even though global warming is happening, we have to stop it from getting worse by becoming more eco-friendly. From a local level, preventative actions can be used by governments to prevent global warming from worsening. An example is that governments can suggest people use electric fans instead of air-conditioners when it is not too hot. They should also recommend that citizens only turn on their air-conditioners when there are 3 or more people at home. World leaders can also put up videos and posters in their countries on social networking sites to encourage people around the world to reduce their consumption of air-conditioning. For reactive actions, governments can set targets for the reduction of carbon emissions. For example, the UK promised to cut all carbon emissions by 2050 to slow down global warming. The imposition of taxes on carbon emissions has also been effective in reducing carbon emissions both in China and in the European Union. The use of preventative and reactive actions altogether by governments around the world can allow for extreme weather caused by climate change to be combatted swiftly.

I would like the world to look clean and fresh for future generations. I would also want the people all over the world to be environmentally friendly. If the world is green and if we are more educated, then we can teach our next generations to do the same. I hope that the future world is non-polluting so that mankind can live in an environment where they will not suffer from the consequences brought about by extreme weather.
