How much has the sea level risen since 2015?
In 2020, global sea level set a new record high—91.3 mm (3.6 inches) above 1993 levels. The rate of sea level rise is accelerating: it has more than doubled from 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century to 0.14 inches (3.6 millimeters) per year from 2006–2015.
How much did the sea level rise in 2014?
In 2014, global average sea level was 2.6 inches (67 mm) above the 1993 average, which is the highest yearly average in the satellite record (1993-present). Overall, sea level continues to rise at a rate of one-eighth of an inch (3.2 mm) per year.
What did James Hansen do for the environment?
Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. He was elected to the National Academy of Sciences in 1995 and was designated by Time Magazine in 2006 as one of the 100 most influential people on Earth.
How much has the sea level rise in the last 10 years?
0.14 inches per year
Long-term measurements of tide gauges and recent satellite data show that global sea level is rising, with the best estimate of the rate of global-average rise over the last decade being 3.6 mm per year (0.14 inches per year).
What will sea levels look like in 2050?
The reality is that different stretches of the coasts will see wildly different rates of oceanic creep. By 2050, the average rise will be 4 to 8 inches along the Pacific, 10 to 14 inches along the Atlantic, and 14 to 18 inches along the Gulf.
How much has the sea level risen since 1990?
The rate of sea level rise has also increased over time. Between 1900 and 1990 studies show that sea level rose between 1.2 millimeters and 1.7 millimeters per year on average. By 2000, that rate had increased to about 3.2 millimeters per year and the rate in 2016 is estimated at 3.4 millimeters per year .
What did James Hansen discover?

What does James Hansen say about climate change?
Former NASA climate scientist James Hansen urged Congress decades ago to act on climate change. Now he says he expects reduced aerosol pollution to lead to a steep temperature rise.
Are sea levels really rising?
Yes, sea level is rising at an increasing rate. With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century.
