“Pielke on ground water extraction causing sea level rise“. Roger Pielke Dr. discovers a new excuse for why sea-level is rising – groundwater extraction! Yes, we’re sucking our way to oblivion. Groundwater extraction is causing sea-level rise! No need to turn off the power plants after-all.
Actually, Groundwater extraction is a well-known contributor to local subsidence. Happens over oil fields. Happens in areas of intensive irrigation by groundwater. Happens naturally in river deltas as the weight of new sediments squeezes water out of underlying sediment. Happens over underground mining operations sometimes. Is it really the cause of sea-level rise, or just a contributing factor?
“Although the role of groundwater depletion in rising sea levels had already been acknowledged, it was not addressed in the most recent IPCC report due to a lack of reliable data to illustrate the severity of the situation. Our study confirms that groundwater depletion is, in fact, a significant factor.” (italics mine)
Hmm… They suggest that about a quarter of the sea-level rise can be attributed to groundwater extraction, which of course means that Pielke and Watts are conveniently forgetting the other three-quarters. Still, that’s 7.62928887 × 1013 gallons of groundwater drawn out every year! An interesting topic, but for Pielke and Watts it’s just a useful factoid that has served the purpose of distracting their readers.
It’s tiresome to repeat these criticisms, but why does Pielke Sr. have to keep making false representations about AGW?
“This is yet another paper that shows the interconnection among the components of the climate system. The attribution of a climate effect (in this case sea level rise) to just one cause (e.g. ocean warming and glacial melt due to positive radiative forcing from anthropogenic greenhouse gases) is too narrow of a perspective.”
Show me a scientific paper that claims that modern sea-level rise is entirely due to AGW! He’s dismissing an argument that was never made. (That’s called a straw-man.)
