Science has revealed again that global sea levels are rising affirming that Climate Change is real and pose real threats to global coastal communities.
A study released yesterday in the Proceedings of the National Academy of Sciences, as reported by CNN, confirmed the rise of the world's oceans brought to wrought by the impact of continuous emissions of greenhouse gases that are causing ice to melt in Greenland and in Antarctica.
The scientific study, led by Professor Steve Nerem, University of Colorado-Boulder, was conducted using satellite data dating back to 1993 to measure sea level rise rather than utilizing tide-gauge data because the satellite measurements allow for a more precise estimate of sea level on the open oceans.
Researchers found that sea level rise is accelerating. The study confirmed the rise of sea level of 2.8 inches (7 centimeters) in 25 years which fits into the range of 0.1 inches (3 millimeters) a year. However, the scientists found that the rise is not constant. Scientists found that continuous emissions of greenhouse gases are warming the Earth's atmosphere and oceans and melting its ice, causing the rate of sea level rise to increase.
"This acceleration," said Professor Nerem, "driven mainly by accelerated melting in Greenland and Antarctica, has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate, to more than 60 centimeters ( about 2-feet) instead of about 30 centimeters (one-foot)," CNN reported.
Hence, with no reductions in the emissions of greenhouse gases, this recent study affirms the Climate model used in the latest International Panel on Climate Change report which show sea level rise to be between 52 and 98 centimeters (between 20 and 38.6 inches) by 2100 - a troubling forecast for coastal communities across the globe.
Therefore, in order to save communities from becoming inundated with flooding, denying governments must accept the science of Climate Change and double all efforts to reducing greenhouse gases. And in lieu of inaction by the unbelievers, individual citizens should invoke their own means to reducing greenhouse gas emissions.
