First you imply that the people that monitor radiation levels have a “weak grasp of the science,”

No, I said the people you linked to had a weak grasp of the science...

then you imply that even if the background radiation increased by more than 600 percent all over the world it has no effect on anything.

I never said anything of the sort- I said it would not come within MANY orders of magnitude of the effect you claim it has.

However, this is all moot because they do not back up the claim of 600% increase with any real data...

Next you imply that the fission process does not cause any heating effect on its surroundings.

Never once did I say that- nor would I ever say that- you seem to be hallucinating about what I wrote...

Human contribution to the background radiation is minuscule:

Fallout from nuclear tests:

Nuclear weapons derive their explosive power from the uncontrolled radioactive break-up of plutonium and uranium. This yields a large number of radioactive daughter products that are blown high into the atmosphere and are carried around the earth. These radioactive elements gradually fall back (fall-out) to earth over a period of many years. During the 1950s and early 1960s, many test explosions were carried out in the atmosphere. In 1963 an Atmospheric Test Ban Treaty was signed and most subsequent tests have been conducted underground. The peak year for radioactive fallout was 1963 and levels have been declining since then. Levels of fallout are now less than ten percent of what they were at peak. We each receive approximately 1 mrem from this source each year

Nuclear Power Plants:

Nuclear power reactors, which use uranium, supply the United States with about 20 percent of its electricity. Our ability to produce power using radioactive materials reduces our reliance on fossil fuels. Nuclear power plant operations account for less than a hundredth of a percent of the average American's total radiation exposure.

The largest single contribution to the background is natural Radon.

Radiation levels have been falling since the Earth was formed

Why do you respond to my posts?

I respond because personal delusion pretending to be science is offensive and harmful.
