Antarctic formation of cold saline deep water is accelerating

These two papers indicate that in the last decade or so, formation of highly saline cold deep water formation around the margin of Antarctica has increased and strengthened. In the long term more cold deep water supply from Antarctica will result in a cooling effect on global climate. Antarctica is the biggest global source of … Continue reading Antarctic formation of cold saline deep water is accelerating

Is cosmic texture a result of Turing reaction-diffusion emergent pattern?

The universe is big - mind-bogglingly so. On its largest scales of billions of lightyears, it has a filamentous, labyrinthine structure that many have noticed bears a resemblance to biological structures, such as the network of neurons in an animal brain - see figure 1 below. Brain cells under the microscope, left, and the billion … Continue reading Is cosmic texture a result of Turing reaction-diffusion emergent pattern?

No difference in protection from covid19 by AstraZeneca and Pfizer vaccines in new unbiased study

There are "no substantial differences" in the protection offered by the UK's two main COVID-19 vaccines, a new study suggests. https://news.sky.com/story/covid-19-no-substantial-difference-in-protection-offered-by-pfizer-and-astrazeneca-vaccines-study-suggests-12439339 Many previous studies have been done across a range of population groups showing that the AstraZeneca vaccine was less effective than the jab made by Pfizer. However, the authors of the new study have … Continue reading No difference in protection from covid19 by AstraZeneca and Pfizer vaccines in new unbiased study

Emergent Thermal Homeostasis: a new paradigm for e-pluribus-unum climate stability

Models of global climate warming from CO2 often frame the earth's temperature as the consequence of a single simple physical system. Radiative balance determines temperature and CO2 perturbs that balance in the direction of warming. End of story. With, of course, an important caveat of "everything else being equal". Envisioning the role of IR-active gasses … Continue reading Emergent Thermal Homeostasis: a new paradigm for e-pluribus-unum climate stability

A global context for Man-made Climate Concerns

Reblogged from https://edmhdotme.wordpress.com/ Earth has existed for some 4,600 million years.  This condensed history sets the current concerns about the level of atmospheric CO2 and the possible recent impact of extra Man-made CO2 affecting global temperature in a rational context. CO2 in the atmosphere To understand the context of current concerns about the increase of … Continue reading A global context for Man-made Climate Concerns
