The efficiency of the Earth as a heat radiator - Part 5

I write these things 'live', with only a general thought as where I am going.  But it's time to sum up.  We are back to my original graphic. This is Dr. Roy Spencer's graph of background microwave measured by satellites.  It's really the old space man's attempt at warming his hands, or a measure of how much heat the Earth is putting out. Dr. Spencer thinks it is a direct measure of

The bit about early life having a devastating environmental impact is just a shot at the greenies.  What goes around comes around, there isn't anything that the Earth hasn't experienced before, many times.  Digression:  We have no logic that takes us from organic molecules to DNA.  For a while I thought about Galactic Seeders, but now I believe in my "Theory of Evolution of Primordial

These are the happy plates at maximum bunching.  From a physics point of view, what does this do the Earth?  Can we think it was nothing?  Nobody has really looked at this, so the world 'consensus' is that nothing much was going on. I, however, think differently, and always have.  That is why I am a nut, and proud to be so.  Nobody has made a buck listening to me, so nobody shall.  :)

This is the inspiration. I've done this before, but I'll do it again.  This is about the physics of the earth, or geophysics, which our warmists never want to think about.  Not that I'm saying they are wrong, but they like to push out all the variables and uncertainties.  I'll never 'deny' what they believe in. If we look at the Earth for last billion years or so that we have a good

In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear

Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal Nature, shows that a big part of the answer lies at the bottom of the

Increase in volcanic eruptions at the end of the ice age caused by melting ice caps and glacial erosion

The combination of erosion and melting ice caps led to a massive increase in volcanic activity at the end of the last ice age, according to new research. As the climate warmed, the ice caps melted, decreasing the pressure on the Earth’s mantle, leading to an increase in both magma production and volcanic eruptions. The researchers, led by the University of Cambridge, have found that erosion also played a major role in the process, and may have contributed to an increase in atmospheric carbon [...]

It’s official: 2015 was the warmest year on record. But those global temperature records only date back to 1850 and become increasingly uncertain the further back you go. Beyond then, we’re reliant on signs left behind in tree rings, ice cores or rocks. So when was the Earth last warmer than the present?The Medieval Warm Period is often cited as the answer. This spell, beginning in roughly 950AD and lasting for three centuries, saw major changes to population centres across the globe. This [...]

Underwater volcanoes may have sent carbon dioxide to the atmosphere at the end of the last ice age

During the last glacial period, Earth's land and sea stored carbon as both dissolved carbon dioxide and biomass. But as the ice receded, water warmed and organisms decayed, that carbon surged into the atmosphere. Most of the released gas came from the atmosphere originally, but in a new study, a data anomaly hints that a small percentage of it came from volcanoes erupting on the ocean

I regularly post this.  It's the plot of the microwave readings from satellites.  The basic idea is that the Earth is a radiating black body, like a stove element.  The poor old planet has to get rid of a lot of heat, solar and geothermal.  The fact that it has done so successfully for a billion years to maintain life, is somewhat heroic. I used to think that this was the only
