One of the most important problems facing our planet is global warming. In order to overcome this world-threatening problem, almost 200 nations reached a historic deal to limit the use of greenhouse gases. The deal includes the U.S. and China, the world’s worst polluters. Over the past 50 years, it was believed that increased volumes of carbon dioxide that came from burning fossil fuels were mainly responsible for global warming. But hydrofluorocarbons (HFCs), which are used in air conditioners and refrigerators, also contribute greatly to global warming. From 2019 to 2028, countries will gradually phase out HFCs, expecting to reduce global warming by 0.5 degrees Celsius.
The world’s increasing temperature leads to many serious problems in weather patterns, rising sea levels, and harmful effects on animal species and their habitats. Countries are experiencing some of the worst typhoons, hurricanes, and floods like never before. Arctic sea ice is melting at a record pace. And countries like the Maldives, the flattest country on Earth, may get swallowed up by the ocean. The whole world has come together to take on a serious issue that affects us all.
