As early as the 1820s some scientists were discussing climate change: sunlight heats the surface of the Earth, and Joseph Fourier suggested that some of the heat radiatedfrom the surface is trapped by the atmosphere before it can escape into space. This is called the greenhouse effect. In 1856 Eunice Newton Footedid tests which showed that the warm...
Sea level is rising because water over 4 °C (39 °F) expands when it gets warmer. Probably more important is the melting of ice sheets. The Antarctica and Greenlandice sheets are melting. Sea level will rise between half and one meter by 2100, and between 2 and 7 meter by 2300. Low-lying areas such as Bangladesh, Florida, the Netherlandsand other ar...
