Plants colonized Earth 100 million years earlier than previously thought

by Bristol University, February 19, 2019 in ScienceDaily

A new study on the timescale of plant evolution has concluded that the first plants to colonize the Earth originated around 500 million years ago — 100 million years earlier than previously thought.

For the first four billion years of Earth’s history, our planet’s continents would have been devoid of all life except microbes.

Once again, climate scientists use a single tree to define global change

by A. Watts, February 19, 2018 in WUWT

From Keele University and the “It’s like deja vu all over again”  department with the leader of the “ship of fools” thrown in for comic relief. Long-time WUWT readers surely remember the single “Most influential tree in the world” from the Yamal fiasco, where the “signal” in one tree (YAD06) biased an entire paper with a hockey stick shape, making it worthless. Well, here we are again with another single tree used to define the entire globe. Obviously they’ve learned nothing, then again, it’s Chris Turney.

Asteroid ‘time capsules’ may help explain how life started on Earth

by Georgia Institute of Technology, February 17, 2018 in ScienceDaily

In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs — and offer an extraterrestrial source for mineral mining. But for one researcher, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system. Having that information gives scientists the starting point they need to reconstruct the complex pathway that got life started on Earth.

The Warming ‘Hole’ Myth

Non-Warming Regions Are More Rule Than Exception 

Earlier this month, the authors of a new paper (Partridge et al., 2018) published in Geophysical Research Letters promulgated the term “warming hole” to describe the cooling temperatures gripping most of the Eastern half of the United States from the late 1950s through 2015
