Stephen Hawking – This is the most dangerous time for our planet

As a theoretical physicist based in Cambridge, I have lived my life in an extraordinarily privileged bubble. Cambridge is an unusual town, centred around one of the world’s great universities. Within that town, the scientific community that I became part of in my 20s is even more rarefied. And within that scientific community, the small group of international theoretical physicists …

Dr. Mercola – How Sunlight Affects Your Mental Health

Sunlight has a profound impact on your mental health — more so than any other weather phenomenon. That’s the conclusion of a recent study looking at links between weather and depression.1 Mental health data from more than 16,000 Brigham Young University students was used. Assessments had been filled out several times by each person over the course of six years. …

Chris Mooney and Jason Samenow – The North Pole is an insane 36 degrees warmer than normal as winter descends

This story has been updated. Political people in the United States are watching the chaos in Washington in the moment. But some people in the science community are watching the chaos somewhere else — the Arctic. It’s polar night there now — the sun isn’t rising in much of the Arctic. That’s when the Arctic is supposed to get super-cold, …

Nadia Prupis – Hottest September on Record Basically “Locks In” 2016 as Hottest Year: NASA

Last month was the hottest September on record, which means 2016 is all but locked into being the hottest year on record, according to new NASA statistics released Tuesday. “With data now available through September, 2016 annual record (~1.25ºC above late 19th [century]) seems locked in,” tweeted Dr. Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies. By a …

Observable universe contains two trillion galaxies, 10 times more than previously thought

October 13, 2016 Space Telescope Science Institute (STScI) https://www.sciencedaily.com/releases/2016/10/161013111709.htm The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA’s Hubble Space Telescope and other observatories. Astronomers came to the surprising conclusion that there are at least 10 times more galaxies in the observable universe than previously thought. This places the universe’s …

Universe has 2 trillion galaxies, astronomers say

There are a dizzying 2 trillion galaxies in the universe, up to 20 times more than previously thought, astronomers reported on Thursday. The surprising finding, based on 3D modeling of images collected over 20 years by the Hubble Space Telescope, was published in the Astronomical Journal. Scientists have puzzled over how many galaxies the cosmos harbors at least since US …

Atlantic Ocean’s slowdown tied to changes in the Southern Hemisphere

The ocean circulation that is responsible for England’s mild climate appears to be slowing down. The shift is not sudden or dramatic, as in the 2004 sci-fi movie “The Day After Tomorrow,” but it is a real effect that has consequences for the climates of eastern North America and Western Europe. Also unlike in that movie, and in theories of …

PETER WADHAMS – As Arctic Ocean Ice Disappears, The Global Climate Impacts Intensify

THE NEWS LAST WEEK THAT SUMMER ICE COVERING THE ARCTIC OCEAN WAS TIED FOR THE SECOND-LOWEST EXTENT ON RECORD IS A SOBERING REMINDER THAT THE PLANET IS SWIFTLY HEADING TOWARD A LARGELY ICE-FREE ARCTIC IN THE WARMER MONTHS, POSSIBLY AS EARLY AS 2020. After that, we can expect the ice-free period in the Arctic basin to expand to three to four months a …

Greenland ice is melting seven percent faster than previously thought

The same hotspot in Earth’s mantle that feeds Iceland’s active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study in the journal Science Advances, the hotspot softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss …
