Beware of climate deceivers' confusion of weather and climate. See this Senator Inhofe video
Weather: our daily experience involves the weather. It's what we get each and every day. There's no way that our daily experience of weather can tell us about our climate's long-term patterns. (What's the difference between weather and climate? NASA)
Climate involves decades, centuries and longer. Climate scientists, like medical scientists, use computer models. Climate scientists also use satellite images and hands-on observation. Using a minimum 30 year cycle, climate scientists study the following: Sun, CO2 emissions, rain, aerosols, oceans, land masses, land-water heating differences, clouds, interactive vegetation, the carbon cycle, rivers, sulphate's, volcanic activity, ocean circulation, corral reefs, tree rings, chemistry, geologic structures, paleontology, glacier melt and more. They also study planets with or without atmospheres.
