IN 2013 scientists found "The Blob," a large mass of heat on the surface of the water in the Gulf of Alaska. Soon after the mass was disvovered, the ice started melting. Puffins were dying, and whales were being caught in water that normally was covered with ice.
Climate change and weather are related, but they are not the same thing. Climate is related to weather patterns, and weather is what you see everyday, such as thunderstorms, snow, and sunshiny days. Humans may be impacting climate change.
Scientists have hypothesized that extreme weather would become worse and more frequent. In 2015, Folsom Lake in California dried up, and cars could drive through it. Hurricane Harvey also was worse than expected because of climate change.
Other storms also were worse because of climate change. Hurricane Irma hit land seven times in the Caribbean and the US, and caused 25 tornadoes.
Scientists use computer models and weather data from the past to imitate climate and predict the weather in the future.
Attribution science is the area of science that tests whether and by how much climate change could be responsible for weather extremes, like high temperatures, droughts, flooding, and hurricanes.
