  • The new study, showing that the top layer of the ocean is warming mainly because of human activity, "means that all the consequences of this warming - sea level rise, higher storm surges - are because of our activity," Marcos said. (agu.org)
  • To calculate the human influence on thermosteric sea level rise, the researchers used the latest climate models that simulate the rise in thermosteric sea level in the top 700 meters (2,297 feet) of the ocean from 1950 to 2005. (agu.org)
  • They then looked at another simulation that examined only the contribution of natural variability to thermosteric sea level rise over this same time period. (agu.org)
  • The difference between these two simulations allowed the researchers to calculate how much of the thermosteric sea level rise can be attributed to emissions of gases associated with human activity. (agu.org)
  • The researchers found that human activity was responsible for an increase in thermosteric sea level rise of .40 millimeters (.016 inches) per year from 1970 to 2005, compared with an increase of .46 millimeters (.019 inches) per year during the same period as a result of both natural variability and human activity. (agu.org)
  • This means that 87 percent of the observed global thermosteric sea level rise of the upper water column of the ocean since 1970 is associated with human activity, according to the paper. (agu.org)
  • The study also found that the human contribution to thermosteric sea level rise varies by region. (agu.org)
