25 Years of Satellite Data Shows Global Warming Is Accelerating Sea Level Rise (usnews.com)

An anonymous reader quotes a report from The Associated Press: Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet (61 centimeters) higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences. Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports. Of the 3 inches (7.5 centimeters) of sea level rise in the past quarter century, about 55 percent is from warmer water expanding, and the rest is from melting ice. But the process is accelerating, and more than three-quarters of that acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

Analyze all of the data

No. It shows a more rapid rise in the last couple of decades, but it does not show an acceleration overall. If you can cherry-pick a 20-25 year period, so can I.

Just for reference, the 25 years of data was not cherry picked. The article being discussed analyzed satellite altimetry data, and the first of the satellite altimetry missions being discussed was TOPEX/Poseidon, which started giving data 25 years ago. 25 years is all the data that exists.

When they analyze all the data that exists, that's the opposite of cherry picking.
