Dr. Don P. Chambers jumps straight into the water with his talk to the audience about the Sea Level changes in the Southeastern United States.
Dr. Chambers begins his discussion with the causes of global mean sea level rise and has some compelling charts.
“For the last 300 years, we have tide gauges,” Chambers explains. “Our longest tide gauge records point to a change in the rate of seal level rise some time in the early to mid- 1800s, with the rate or rise increasing from <1mm/year to nearly 2mm/year.”
Dr. Chambers says, “What we know with certainty is that sea level is rising and that it is rising faster on average in the 20th Century than at any time in the last 3000 years. It's all about the ice. Models for ice dynamics are still crude and likely underestimate potential.”
Dr. Chambers is an Associate Professor at the College of Marine Science, University of South Florida, and is an internationally recognized expert in the field of sea level science.
His specialty is in using satellite observations to measure sea level change, both globally and regionally and he has served on numerous national and international science committees, including as a Lead Author on the 5th Climate Assessment of the Intergovernmental Panel on Climate Change (IPCC), published in September 2013.
