Today’s “Planet Earth Report” –Scientists Have Uncovered a Very Scary Climate Change Precedent

“During the rise of mammals, Earth’s temperatures spiked in a scary way that the planet may experience again soon. They were strange days at the beginning of the age of mammals. The planet was still hungover from the astonishing disappearance of its marquee superstars, the dinosaurs. Earth’s newest crater was still a smoldering system of hydrothermal vents, roiling under the Gulf of Mexico. In the wake of Armageddon our shell-shocked ancestors meekly negotiated new roles on a planet they inherited quite by accident.” (more…)

Our Solar System –“Is a Rosetta Stone We Can Use to Decipher Alien Worlds”

“We use our own solar system and all we know about its incredible diversity of fascinating worlds as our Rosetta Stone,” said co-author Lisa Kaltenegger, associate professor of astronomy and director of the Carl Sagan Institute. “With this catalog of light-fingerprints, we will be able to compare new observations of exoplanets to objects in our own solar system—including the gaseous worlds of Jupiter and Saturn, the icy worlds of Europa, the volcanic world of Io and our own life-filled planet.

“Leak in the Biological Pump” — May Have Warmed the Climate for Past 11,000 years, Encouraging Human Civilization

“We often refer to the Southern Ocean as a leak in the biological pump,” said Daniel Sigman, the Dusenbury Professor of Geological and Geophysical Sciences at Princeton University, who found that an increase in the Southern Ocean’s upwelling could be responsible for stabilizing the climate of the Holocene, the period reaching more than 10,000 years before the Industrial Revolution.

“Carbon-Dioxide Hell” –NASA Nixes the Greening of Mars for Human Colonization

Although the surface of Mars is inhospitable to known forms of life today, features that resemble dry riverbeds and mineral deposits that only form in the presence of liquid water provide evidence that, in the distant past, the Martian climate supported liquid water at the surface. But solar radiation and solar wind can remove both water vapor and CO2 from the Martian atmosphere. (more…)

The Alien Observatory: “Rio 2.0 Scale” –Astronomers Poised to Evaluate Signals from Extraterrestrial Civilizations


“When a team of Russian astronomers reported in 2015 that a telescope in the Caucasus region had intercepted a mysterious signal from a distant star, talk of extraterrestrials was not far behind. As some asked: was this proof aliens were trying to contact us? The answer came soon enough. Follow-up observations from other telescopes failed to confirm the signal and researchers came to the conclusion that the source of the signal was far closer to home. The chances are it came from a passing plane or a person on a citizens band radio, or was down to a glitch in the telescope’s electronics.”
