Climate change and overfishing - 12,000 years ago

These are nothing new - the idiots today think they invented it. From the London Daily Mail:

Fossils discovered in the Sahara reveal catfish and tilapia swam in rivers 12,000 years ago but died off from over fishing and climate changes

• • Experts found 17,551 identifiable fossilized remains in the Sahara near Lybia
  • Approximately 80 percent of the fossils belonged to catfish and tilapia fish
  • The remains had cut and burn marks on them, suggesting they fed early humans
  • The catfish survived longer than tilapia due to their accessory breathing organs

The Saharan environment in southwest Libya is a sandy, dry world, but fossil records show it was flowing with water and life some 12,000 years ago.

Paleontologists uncovered 17,551 identifiable remains on the Tadrart Acacus Mountains, with 80 percent belonging to fish that fed early humans during the Holocene period.

The remains show there was once an abundance of catfish and tilapia in the area, which died off from over fishing – the bones had cut marks and traces of burning.

Much more at the site. Our star is variable and we are only just beginning to understand the effects it has on our climate. The Modern Warm Period is winding to a close and everything points to a very quiet sun and colder weather here on Earth.
