A book getting very positive reviews on amazon.com is ‘Rational Readings on Environmental Concerns‘ (edited by Jay H. Lehr). Dr Lehr has been a champion of the skeptic cause exposing scientific abuse by climate alarmists. We feature his articles on Principia Scientific International.

In an article in The Skeptical Inquirer May/June 2019 issue, an author dissects a Flat Earther school board presentation,seemingly surprised that it was “intelligently designed,” as if the key issue with junk science such as the flat earth model was the low intelligence, or poor communication skills, of its adherents.

The climate of the Earth has been constantly changing during its entire 4.6-billion-year history. Variations in our planet’s average temperature due to natural causes have ranged over a span of 60 degrees Fahrenheit.

The National Park Service (NPS) is trying to backtrack from their failed predictions of climate doom. They recently removed a warning from a Glacier National Park claiming that glaciers “will all be gone” by 2020 due to global warming fears.

It appears we have begun a new solar minimum. Based on recent NASA photographs of the sun, the total absence of sunspots, and other data from the Langley Research Lab at NASA, that is a reliable assumption.

As a nuclear physicist, I can report that HBO’s Chernobyl was sensational fiction inspired by real events, not a factual documentary.

The International Journal of Environmental Research thankfully offers a scathing debunk of a recent paper on ticks in Northwestern Ontario which shamelessly promotes climate alarm.

Once again, an independent scientist demonstrates how shoddy peer review (which suits the global warming agenda) undermines the science publishing industry.

An international team led by the University of Göttingen (Germany) with participation by researchers from the Instituto de Astrofísica de Canarias (IAC) have discovered, using the CARMENES high-resolution spectrograph at the Calar Alto Observatory (Almería) two new planets like the Earth around one of the closest stars within our galactic neighbourhood.

A key claim of man-made global warming theory is that there is a direct link between annual ‘fossil fuel’ emissions and annual changes in atmospheric CO2. But a new study, relying solely on government data, disproves this.

In the first 5½ months of 2019, over 200 scientific papers have been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…  or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources.

A thin polar bear has wandered more than 1000km south of the Kara Sea into the Siberian town of Norilsk, which has happened at least once before in the 1970s.

The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) has issued annual vaccine recommendations for the U.S. civilian population since 1995.

Here is an innovative wind energy device which is more nature-friendly than the ‘bird chopper’ designs preferred by so-called environmentalists (pictured). It is designed by PSI contributor and professional engineer, Robert Beatty.

Did you know that climate science and mainstream academia believes that the Sun can’t heat the Earth? It is true.

The field of climate physics and mainstream science believes that sunshine can only heat any location on the Earth to -18 degrees Celsius or 0F, and that any temperatures on the Earth higher than that are from the air warming itself up some more.

The Food and Drug Administration (FDA) has quietly revealed some troubling information about a class of toxic chemicals that the agency found in significant levels in our food supply.

Here we are at the middle of June when most polar bears are pretty much done with hunting seals for the season.

And despite hand-wringing from some quarters, sea ice extent is down only marginally from average at this time of year and certainly not enough to impact polar bear survival.
