Seas rose more than five inches in the 20th century, and it is expected that they may rise a couple more feet in the current century. Study, published in Nature Climate Change by an international team of scientists, presented results of analysis of the sea level rise for the last 3000 years.
By comparing the results of their modeling, which included natural and human influences on temperatures and sea levels, including changes in solar radiation and volcanic eruptions, the researchers could account for about three-quarters of sea level rise detected in a century of tide gauge and other observations. The modeling revealed, that until around 1950, the effects of heat-reflecting pollution known as aerosols helped offset the sea-rising effects of heat-trapping greenhouse gas pollution. However, around 1970, the warming effects of greenhouse gas pollution raised sharply - but the cooling effects of aerosols were diminished because of clean air laws in developed countries, leading to accelerated warming and sea level rise.
