Extreme weather is the biggest problem in the world. A lot of people still think that climate change is something happening far away, that it is not their business, even though they may strive to combat the issue, it will not change anything. This is the worst approach to fighting climate change. We need to stay together. If everyone can make an effort to fight the problem, the power we have is enormous. There are plenty of methods to improve the problem. The most important method is to apply a low-carbon lifestyle in to our life. This will be sustainable and helpful. For example, we can use less electricity by adjusting air-conditioner to 25 degree celsius. That is enough to enjoy a comfortable environment at home. Less electricity means less carbon dioxide emissions. We should keep this concept in mind. Otherwise, it will become even more serious if we do not take action now to slow down global warming.
