Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 200 millimetres (8 inches) per century, or 2 mm per year.
Satellites measured the average sea level rise of about 3.5 mm per year from 1993 to 2009.
A common error in climate debate is to focus on short term data instead of looking at long time trends. All sea level graphs (as well as temperature graphs) zig zag up and down. Some years oceans cool and sea levels go down, other years oceans warm and sea levels rise, from cyclic events like La Niña (cooling) and El Niño (warming).
A:Since 2009 we have seen a decline in sea level height of 6 mm in 2010 and 5 mm in 2011. This year is on tract to be another year of decline rather then increase. When we look at the actual long term data, we see that this century is running at about the same sea level increase rates as the past few centuries have. (just under 2 mm a year)It is important to note that the ocean current changes have no impact on global ocean temperatures. La Nina type events can change local land temperatures, but not global ocean temperatures and would have no affect on the issue of sea levels or temperatures globally.

What is the trend of carbon dioxide concentrated in the atmosphere?
The trend, unfortunately, is rising. Two hundred years ago carbon dioxide levels were around 280 ppm (parts per million) and had been that way for thousands of years. Now (2014) levels have reached 400 ppm or 0.04%. They have been rising every year since global warming began.
When will the sea level be expected to rise?
Sea levels are already rising. They rose 20 centimetres over the course of the twentieth century. During the last decade, however, mean global sea levels have been rising at approximately 2.9 to 3.4 millimetres per year. And they are now predicted to rise a further 90 to 150 centimetres over the course of the twenty-first century, depending in part on what efforts we make to reduce our greenhouse emissions.
Is the number of icebergs increasing or decreasing?
Decreasing as human induced Global Warming ravages the Earth.
What are the current sea level rise rates?
Since 1900 sea levels have been rising by about 2 mm per year. (200 mm, or 20 cm, or 8 inches in 100 years) Since 1993 sea levels have been rising by about 3 mm per year. (30 mm or 3 cm or 1.18 inches in 10 years)
What time of year does global warming happen?
Global warming is a long-term trend of rising global temperatures due to increased greenhouse gases in the atmosphere, mainly caused by human activities. It is not limited to a specific time of year; rather, it is a continuous process that is affecting the Earth's climate overall.
What has happened to the global sea level over the past century?
Sea levels rose 20 centimetres over the course of the twentieth century, an average of only 2 millimetres per year. During the last decade, however, mean global sea levels have been rising at approximately 2.9 to 3.4 millimetres per year.
What is the trend of carbon dioxide concentrated in the atmosphere?

Is sea level rising as a result of global warming?
Yes it is. For most of the last century sea levels rose at 2 mm a year, and since the later years of the 20th Century they have been rising at 3 mm a year. Warmer oceans mean that the warm water expands. This is the main cause of the rise. A secondary cause is the melting of land ice.

Rising Fast
Do numbers rise every year for global warming?
Yes, global temperatures have been rising on average every year due to human activities such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. This leads to the phenomenon known as global warming.
When was the last global warming?
Global warming is an ongoing phenomenon, with temperatures steadily rising over the past few decades due to increased levels of greenhouse gases in the atmosphere. The most recent scientific data shows that global temperatures continue to increase, leading to more frequent extreme weather events and disruptions in ecosystems.
When will the sea level be expected to rise?
Sea levels are already rising. They rose 20 centimetres over the course of the twentieth century. During the last decade, however, mean global sea levels have been rising at approximately 2.9 to 3.4 millimetres per year. And they are now predicted to rise a further 90 to 150 centimetres over the course of the twenty-first century, depending in part on what efforts we make to reduce our greenhouse emissions.

How much have sea levels risen since 1992?
Sea levels have risen approximately 3.6 inches (9.1 cm) globally since 1992, as measured by satellite data. This rise is primarily due to the melting of glaciers and ice caps and the thermal expansion of seawater caused by global warming.
What time of year does global warming happen?
Global warming is a long-term trend of rising global temperatures due to increased greenhouse gases in the atmosphere, mainly caused by human activities. It is not limited to a specific time of year; rather, it is a continuous process that is affecting the Earth's climate overall.
Average temperatures are rising each year because of accumulations of carbon in the atmosphere?
Yes, the increase in carbon in the atmosphere, primarily from human activities like burning fossil fuels, is trapping more heat and causing global temperatures to rise. This phenomenon, known as global warming, leads to changes in climate patterns and can have far-reaching impacts on ecosystems, weather patterns, and sea levels.
