Compared with the past a century of observations, climate change models often underestimate the rise in sea level. This difference may indicate a problem climate models exist. These models attempt to explain the melting of glaciers and ice caps impact, as well as warmer waters can contain more species that fact. Or, it may just be the product of a tide gauge simple sea level records. Early 20th century, this device particularly uneven.
Currently, the fact that the gap between the model results and observations researchers did not think big. A new study for the tide gauge data, found that between 1901 to 1990, sea level rose by only 1.2 millimeters per year. The researchers recently published online in the relevant outcomes “Nature” magazine. This figure is less than the 2011 rate of rise of the calculated 1.5 mm per year, and is the latest report of the Intergovernmental Panel on Climate Change (IPCC) are cited.
The researchers said the results are closer to the IPCC climate models to calculate the rate of rise of 0.5 millimeters per year. The study relies sophisticated probabilistic methods can identify with sparse tide gauge related to the distribution model. Scientists also found that from 1993 to 2010, sea level has risen 3 millimeters per year. This is consistent with other tide gauge analysis conclusions.
In any case, scientists say, from the 20th century to the 21st century, the rate of increase has supported leap climate models have been telling the “story”: Sea levels are rising to the frightening acceleration.
