Tipping Point?

Many climate catastrophists claim that only a few more degrees in temperature or a few parts per million of a greenhouse gas might push our planet over the edge into a devastating hothouse environment with warming oceans, melting ice caps, rising sea levels, and more violent storms. Are tipping points unprecedented in paleoclimate history with rapid temperature changes leading to extreme warming or cooling climates? Let’s look at some paleoclimate data for ourselves.

Fossil foraminifera can be used to identify the conditions in which the enclosing sediments accumulated. We can use the oxygen-18 ratios to recognize glacial and warm episodes during the current Ice Age. We know that during the last million years of the Late Pleistocene Ice Age the planet has continued to cool initiating a glacial-interglacial period of around 100 thousand years. The Milankovitch 100k year orbital Eccentricity cycle appears to modulate this longer period. Over the previous 2 million years of the early Pleistocene the planet was warmer with the glacial-interglacial period a steady 40 thousand years seemingly driven by the 40k year Obliquity cycle.


High resolution paleoclimate proxy records from Greenland ice cores (Boers, 2018) show that the last 120-thousand-year glacial interval was punctuated by abrupt climatic transitions called Dansgaard–Oeschger (D-O) events. These events are characterized by rapid temperature increases over Greenland of up to 15 deg C within a few decades. The course of a D-O event starts with an abrupt warming, followed by a cooling period lasting a few hundred years where temperatures eventually return to the normal cold of the glacial period. The cause of these transitions remains unclear. However, these transitions may be influenced by amplification of cyclic solar forcings,

Sea Surface Temperatures: West Versus East Coast.

Perhaps, this blog spends too much time talking about the atmosphere, so to make amends today, let's see what is happening to the temperature of the ocean surface.  And see whether anything unusual is going on.

 Let's start with yesterday's sea surface temperatures around North America (below).  Sorry, it is all in °C.   Keep in mind that 10°C is roughly 50F,  20°C is around 68F, and 30°C is approximately 86F.

The eastern Pacific near the West Coast is cold (about 50F), with central California's waters a bit cooler than ours. You must head to the southern tip of the Baja Peninsula to find the water warm enough for comfortable swimming.


The East Coast is a study in contrasts.  The water off of New England is crazy cold (dropping below 7C), while the uber-warm Gulf Stream is found along the west coast of Florida, moves past the Carolinas, and then heads northeastward into the Atlantic.

California Mayor Sounds the Alarm as Migrants Hit 25-Year High
Story by Nick Mordowanec • 14h

ACalifornia mayor says a record number of border encounters in his county is further proof of an unprecedented lack of federal enforcement.

El Cajon Mayor Bill Wells told Newsweek via phone that in April the San Diego County sector surpassed all other sectors in border encounters for the first time in 25 years. San Diego experienced 37,370 encounters, surpassing Tucson (31,240), El Paso (30,410) and Del Rio (10,275).
 
"We've become the No. 1 sector in America for crossing the border," Wells said, warning about a humanitarian crisis confounded by security risks for locals and the nation.

The El Cajon Station, responsible for roughly 10 miles of international border with Mexico, is 18 miles northeast of San Diego sector headquarters.

CNN Panelist on the cross examination of Stormy Daniels: “Her responses were disastrous.. ‘Do you hate Donald Trump?’.. ‘Yes’ — of course she does… When the witness hates the person whose liberty is at stake, that’s a big damn deal and she’s putting out Tweets fantasizing about him being in jail.. That really undermines the credibility.”. (Video)
