On December 23, 1947, three researchers at Bell labs demonstrated a new device to colleagues. The device, a solid-state replacement for the audion tube, represented the pinnacle of the quest to provide amplification of electronic communication.

Social Justice Education in America is a comprehensive examination of the inner workings of social justice advocates at more than 60 universities and how they have insinuated themselves into the university system to propagandize students.

Svante Arrhenius (1859-1927) was a Swedish scientist who first claimed that the burning of hydrocarbons like coal, oil, gas, peat, and wood may cause global warming.

In 1895, he calculated (incorrectly) that a doubling of the atmospheric CO2 concentration would lead to a 4-5^o C rise in global temperature.

It hasn’t been entirely smooth sailing, but The Ocean Cleanup is now calling an end to a first successful mission to collect plastic from the Great Pacific Garbage Patch, today showing off the pile of trash on the shores of Vancouver.

An ancient village off the coast of Israel used boulders to build a wall thousands of years ago to protect its homes from rising sea levels — the move was unsuccessful, according to a study published Wednesday.

“While the president rages, the world melts,” keened The Washington Post in an editorial over the weekend.

As President Trump spent another week rage-tweeting, the world continued to warm, and the consequences became ever-clearer — and more alarming.

Estimates used by climate scientists to predict the rate at which the world’s ice sheets will melt are still uncertain despite advancements in technology, new research shows.

These ice sheet estimates feed directly into projections of sea-level rise resulting from climate change.

The Mahout, the Elephant and the Path. The mahout represents the rational and reasoned. If the mahout clearly understands where he needs to go he’ll direct his charge that way. The elephant represents the subconscious.

It seems incredible that the subconscious mind was first postulated by Sigmund Freud.  If you are elderly it is likely that your grandparents imagined that the entire content of their mind was accessible to conscious contemplation.

German evolutionary biologist and physiologist Prof. Dr. Ulrich Kutschera told in an interview that “CO2 is a blessing for mankind” and that the claimed “97% consensus” among scientists is “a myth.”

Cannon Points are typically geographic promontories on lakes, rivers, and ocean fronts that were useful for locating cannons that might be a formidable deterrence to any invaders.

Cannons — Not only for Defense

In times of peace and in remote communities, they were more or less critical points from where cannon shots could be heard throughout the area, to alert the community to important events and news.

There has been a 4–6% decline in Arctic Sea Ice over the satellite era (see graphs below). Antarctic sea ice increased almost the same amount in 2016–2018, but it is now down slightly (1–3%) as well. It is hard to be sure that this change is significant as the longer term records required to be certain do not exist.

The average American ate some 220 pounds of red meat and poultry in 2018, according to the US Department of Agriculture, surpassing a record set in 2004.

But some politicians have joined anti-meat and climate change activists in a massive effort to restructure the American diet – and to ensure … and mandate … that the rest of the world will be stuck with a mostly plant-based diet.

The New Jersey legislature came very close to enacting a law, S. 2173, that would end religious or philosophical exemptions parents use to opt-out of vaccinating their children who attend state schools.
