I have been honoured with a drive-by posting from nickreality65 explaining why back radiation does not exist.
Here is his argument;-
The title is gratuitous click-bait.
There is no science, just a Gif animation I could not resist posting.
As the last post on this subject was so popular,
here is the remake released straight to video.

Simplified thermodynamic system.
If Each ball=40J
Then without the Green box the Blue box would receive and emit 150J/sec and working back from S.B, emitted E=T^4, has a temp of ~ 196KWith the Green box returning and extra 10J/sec to the Blue box as back radiation it emits 160J/sec and has a temp of 200K.
The Green box receiving and emitting 40J/sec has a temp of ~141K
For the context and further explanation please see the full post.
President Trump has finally managed to make good on one of his many campaign promises.
He has pulled out of the Paris agreement.
Muslims are still un-banned, Obamacare un-repealed and Mexicans un-walled.
But Trump can claim real progress in having repudiated the Paris agreement to join with all other Nations (except Syria and Nicaragua), in reducing future CO2 emissions by a self-selected voluntary amount.
While such a withdrawal involves very little change in actions, Trump can point to other steps taken to roll back clean air and water regulations and cut funding for renewable energy research in keeping his larger promise to reduce job-inhibiting regulation and government subsidy of environmental issues.
This one valid success in meeting his manifesto pledges has not been greeted with wide praise. In fact it seems to have increased the expressed commitment of all those within the Paris agreement. With wider signs that the importance of future CO2 emission reduction is gaining support.
Like many people I followed the US elections with great interest because of Trump. Checking the news everyday to see what outlandish nonsense he was spouting this time. Like many others the chances of him actually winning seemed small, even with a very unpopular opponent. Continue reading
Occasionally a group of activists will decide that their position would benefit from media coverage of a
“We the undersigned, urge and implore….”
letter to prominent media or as an open letter to the government if they can get wide publicity for the petition.
Season’s greetings, best Xmass wishes, solstice salutations… click to see the animated version – Continue reading
In response to a wish expressed elsewhere that a graph showing the lack of a pause after 1998 was updated with the most recent data I had a go and got this.
In the process I discover that there is a fad again for animated GIFs.
This reminds me of the very early days when the flashing GIF was the height of cool, and packing the most into the smallest file size was almost an art. You certainly had to be crafty. Continue reading
Earth memory and carbon dioxide.
The recent passing of the 400ppm level of CO2 will persist in the memory of the Earth for millennia. The chemical changes as well as the climate effects are slow to dissipate even if there is no further anthropogenic perturbation of the system.
But the Earth can remember bigger and older changes. The Earth remembers by writing the events into the geology of the surface. Small changes only write a small memory that may get overwritten by subsequent events. But the big changes leave traces that persists for many millions of years. Continue reading
