Sea Change. Since around the time of the Industrial Revolution (the late 18th and early 19th centuries), Earth's atmosphere has warmed by a little less than 1Â° C (1.8Â° F) (Figure 2). In turn, the ocean has also risen by about 15 centimeters (6 inches) over the past 100 years -- for two reasons. First, when water warms up, it expands, in much the same way as a solid does when it heats up.
A bit of background: For the last 10,000 years, the Earthâs temperature has been fairly steady, fluctuating by only about one degree Celsius. Yes, itâs risen and fallen, but all of human existence, everything we have ever done as a species has happened in this narrow temperature range.
