“Data is king”: Analysis confirms projections of sea level rise models
No more computer models or projections. Finally – concrete data.
A scientific paper published in February may pave the way for a new conversation about rising sea levels using data instead of projections.
Gary Mitchum, co-author of the paper and Associate Dean at the College of Marine Science at the University of South Florida, says the research is more than just another explanation of the effects of global climate change.
“In science, data is king,” Mitchum said. “I’ve been telling people I think it’s a game-changer in that the discussion can now switch from is this just an error in the models, the computer models, or is it really in the data?’’
The paper immediately received international attention and went viral within the scientific community.
The team of researchers began compiling data in 1993. They released the statistics from satellite altimetry, the measurement of height or altitude from a satellite.
“We’re hoping that what this is going to do is allow people to stop worrying about the fact that it’s only the models seeing it, that we actually see it in the data now too and we can have a conversation about what we need to be doing,” Mitchum said.
Using data from 25 years of observation, researchers concluded that previous projections by computer models were accurate with 99 percent confidence. The global average sea level rose about 3 millimeters per year.
Now, the scientific community has recorded data that confirms these research methods.
