“Scientists who have recently attempted to detect an anthropogenic signal in regional sea level rise trends have had to admit that there is ‘no observable sea-level effect of anthropogenic global warming’,” Richard points out, listing four peer-reviewed studies published this year that have all come to the same conclusion.
In a paper published on May 18, Hindumathi Palanisamy at the Laboratoire d’Etudes en Geophysique et Oceanograhie Spatiales (LEGOS) in Toulouse, France and her co-authors explain that “sea level is an integrated climate parameter that involves interactions of all components of the climate system (oceans, ice sheets, glaciers, atmosphere, and land water reservoirs) on a wide range of spatial and temporal scales….
“Since 1993, sea level variations have been measured precisely by satellite altimetry. They indicated a faster sea level rise of 3.3 mm/yr over 1993-2015. Owing to their global coverage, they also reveal a strong regional seal level variability that sometimes is several times greater than the global mean sea level rise,” the researchers state.
“Considering the highly negative impact of sea level rise for society, monitoring sea level change and understanding its causes are henceforth high priorities.”
Comparing sea level changes between 1950 and 2009 in the Indian Ocean, South China and Caribbean Seas, Palanisamy’s team found that the “tropical Pacific displays the highest magnitude of sea level variations.”
the remaining residual sea level trend pattern does not correspond to externally forced anthropogenic sea level signalHowever, by studying “sea level spatial trend patterns in the tropical Pacific and attempting to eliminate signal corresponding to the main internal climate mode, we show that the remaining residual sea level trend pattern does not correspond to externally forced anthropogenic sea level signal.”
Another group of scientists led by Mohammad Hadi Bordbar from the Helmholtz Centre for Ocean Research in Kiel, Germany also concluded in a study published in April that the recent sea level trends in the tropical Pacific “are still within the range of long-term internal decadal variability.
“Further, such variability strengthens in response to enhanced greenhouse gas concentrations, which may further hinder detection of anthropogenic climate signals in that region,” the study found.
So what you’re saying is that the horror stories you’ve been cooking up about us all drowning from Global Warming haven’t happened but they may not have happened because of Global Warming.
Think about that for a second…. 🙂
