Why Antarctica And Greenland Ice Melt is Not Serious
Writing in the journal Nature, scientists at Columbia University and the University of Victoria, British Columbia report,
The Antarctic continent has not warmed in the last seven decades, despite a monotonic increase in the atmospheric concentration of greenhouse gases. ”The scientists also observe that over the past several decades, “Antarctic sea ice area has modestly expanded.”https://www.nature.com/articles/s41612-020-00143-w
Seawater is Alkaline and the Changes are Miniscule and Harmless
Although climate models suggest the ocean’s surface pH has dropped from pH 8.2 to 8.1 since 1750 that change was never actually measured. The pH drop is merely a modeled conjecture2 that is, unfortunately, constantly repeated as fact. The concept of pH was first introduced by in 1909 and the pH concept was not modernized in Chemistry until the 1920s. Citrus growers later developed field instruments to measure pH in the 1930s.
Greenland Ice Melting Will Cause Dangerous Sea Level Rise
The Amount Of Melting Ice Isn’t Significant
Climate activists, including government bureaucrats, claim the Greenland ice sheet is melting six times faster than it was 30 years ago. Thirty years ago, the Greenland ice sheet was barely melting at all. “Six times” almost no ice loss remains almost no ice loss.
Sea-level measurements contradict claims that Greenland ice loss threatens coastal flooding. NASA satellite instruments, with readings dating back to 1993, show global sea level rising at a pace of merely 1.2 inches per decade, which is not significantly different than the typical rate of sea-level rise since the mid-1800s.
Sea Level Rise is Accelerating Dramatically
Most of the recent alarmism on sea level rise has been due to climate model projections, which foresee a drastic and accelerating increase in sea level rise in the future.
Ocean tide gauge data shows that the sea level trend has not changed in over 100 years, and show no signs of drastic acceleration. In New York City, sea level has risen only 0.94 feet in 100 years, and started well before human carbon dioxide emissions were significant. The trend is unchanged since 1856. All of the perceived acceleration comes from satellite measurements and could be within the range of measurement error.
