Sea Level Could Rise 3 Feet by 2100, Climate Panel Finds
By JUSTIN GILLIS, NYT
An international team of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could rise by more than three feet by the end of the century if emissions continue at a runaway pace.
The scientists, whose findings are reported in a summary of the next big United Nations climate report, largely dismiss a recent slowdown in the pace of warming, which is often cited by climate change contrarians, as probably related to short-term factors. The report emphasizes that the basic facts giving rise to global alarm about future climate change are more established than ever, and it reiterates that the consequences of runaway emissions are likely to be profound.
“It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010,” the draft report says. “There is high confidence that this has warmed the ocean, melted snow and ice, raised global mean sea level, and changed some climate extremes in the second half of the 20th century.”
The “extremely likely” language is stronger than in the last major United Nations report, published in 2007, and it means the authors of the draft document are now 95 percent to 100 percent confident that human activity is the primary influence on planetary warming. In the 2007 report, they said they were 90 percent to 100 percent certain on that issue.

sea level could also fall by 3 feet. What's going to happen in 2020 that we can actually measure when most of us are sstill here to confirm or deny the cataclysmic prediction? We're not just going to wake up in 2100 and the oceans just rose 3 feet. The rise will have to occur graudally. So, let's start with 2020. What will the sea levels be in 6 years? Predict now and then we can verify when 2020 rolls around to see if you are right? Same with 2030, 2040, and so on to 2100. Please tell us exactly what the sea levels will be every 10 years until 2100 starting with 2020.
Don't make outlandish predictions that almost no one alive today will be around to see whether or not the prediction came to fruition. Make a prediction closer to the future and let's see if you're right.
