California “right to water” means more state/federal regulations

Alejo (D-Salinas) pushes “right to water” theme in Nov. 14 hearing of the Environmental Safety and Toxic Materials Committee. Click here….

The poor and disadvantaged communities that lack drinking water are just another “constituency group” in the Democrat class warfare playbook…

Now that California is a one-party dictatorship, it really does not matter much what is said in such hearings. This is a soap box issue for the Democrats…..so expect more to be said, than done….

 

North Atlantic Ocean cooled from 1953-2007

The “missing heat” of global warming does not go into the ocean….in fact, it has never existed in the first place.

C. Mauritzen, A. Melsom, and R.T. Sutton. Importance of density-compensated temperature change for deep North Atlantic Ocean heat uptake. Nature GeoscienceYear published:(2012)DOI:doi:10.1038/ngeo1639.

The efficiency with which the oceans take up heat has a significant influence on the rate of global warming. Warming of the ocean above 700 m over the past few decades has been well documented. However, most of the ocean lies below 700 m. Here we analyse observations of heat uptake into the deep North Atlantic. We find that the extratropical North Atlantic as a whole warmed by 1.45±0.5×1022 J between 1955 and 2005, but Lower North Atlantic Deep Water cooled, most likely as an adjustment from an early twentieth-century warm period. In contrast, the heat content of Upper North Atlantic Deep Water exhibited strong decadal variability. We demonstrate and quantify the importance of density-compensated temperature anomalies for long-term heat uptake into the deep North Atlantic. These anomalies form in the subpolar gyre and propagate equatorwards. High salinity in the subpolar gyre is a key requirement for this mechanism. In the past 50 years, suitable conditions have occurred only twice: first during the 1960s and again during the past decade. We conclude that heat take through density-compensated temperature anomalies will contribute to deep ocean heat uptake in the near term. In the longer term, the importance of this mechanism will be determined by competition between the multiple processes that influence subpolar gyre salinity in a changing climate.
