'American Coyotes' Series

Traveling by Jeep, boat and foot, Tribune-Review investigative reporter Carl Prine and photojournalist Justin Merriman covered nearly 2,000 miles over two months along the border with Mexico to report on coyotes — the human traffickers who bring illegal immigrants into the United States. Most are Americans working for money and/or drugs. This series reports how their operations have a major impact on life for residents and the environment along the border — and beyond.

Climate alarmists who blame mankind's "smokestack" emissions betray their unscientific slant by ignoring the effects of pre-industrial clearing of forests, which a new study documents.

Six French researchers report in the journal Science that ancient sediment cores from the Congo River's mouth show a significant human role "in changing the landscapes of Central Africa" about 3,500 years ago, according to Scientific American.

The cores show river sediments increased suddenly, without increased rainfall, at the time when the Bantu people "brought farming into the region."

Clearing forests to plant oil palm, pearl millet and yams -- "crops that need plenty of sunlight" -- they helped create African savannas, previously thought to be the result of "climate change" only.

Scientific American says the paper doesn't settle which came first, savannas or agriculture. But by demonstrating that clearing forests -- a practice that continues today -- can change climate, the paper exposes a glaring blind spot in global-warming alarmists' "reasoning."

It's a reminder that "settled" science about incredibly complex ecosystems is anything but settled -- and that when politics enters scientific debate, such debate becomes anything but serious and scientific.
