From this article, I have learnt what the effects of climate change are. Firstly, Sea level is rising. During the 20th century, sea level rose about 15 cm (6 inches) due to melting glaciers and expansion of warmer seawater. It could rise much more than that in the next 100 years. Arctic sea ice is melting. The summer thickness of sea ice is about half of what it was in 1950. This is causing the Arctic to warm up faster.
Also, Ecosystems are changing. As temperatures warm, animals and plants may either look for a cooler place to live or die. Species that are vulnerable include endangered species, coral reefs, and polar animals. Warming has also caused changes in the timing of spring events and the length of the growing season. Hurricanes have changed in frequency and strength. There is evidence that the number of intense hurricanes has increased in the Atlantic since 1970. Scientists continue to study whether climate is the cause.
Also, heat waves more frequent. It is likely that heat waves have become more common in more areas of the world. Seawater is becoming more acidic. When carbon dioxide, a greenhouse gas, gets into the oceans, it makes the water more acidic. This could impact coral reefs and other marine life.
From this article, I have learnt many things about the effects of climate change. By reading this article, I hope that I can influence others not to contribute to the effects of climate change.
