Fragile Planet?: Study Finds Earth Is Weaker Than Once Thought

CBS Local — Scientists at the University of Pennsylvania are saying that the Earth may be even more fragile than most people thought. According to new findings about the substance that makes up most of the planet’s mantle, researchers are changing their theories on how the world’s tectonic plates move under us. The researchers say olivine, which is found throughout the Earth’s interior, is weaker than scientists had thought for years. Geologists reportedly found that the grain size of the mineral is much larger than previously estimated which leads to a weaker material. The scientists say that the finer the grain, the stronger the rock. The findings are now painting a different picture of how researchers understand how tectonic plates form, shift, twist into volcanoes, and even trigger earthquakes. The research team says scientists have been trying to guess how strong olivine was for 40 years until their experiments opened a new door in geology. “We need to understand the mechanical behavior of olivine, which is the most common mineral in the upper mantle of Earth,” associate professor David Goldsby said, via Science Daily. Goldsby and his fellow scientists are hoping the findings will also help them understand how the faults in the Earth’s surface move and erode over time. “Different faults have a similar roughness, and there’s an idea published recently that says you might get those patterns because the strength of the materials on the fault surface increases with the decreasing scale of roughness,” doctoral student Christopher Thom said.

This Species Will Outlive The Sun And Be The Last Living Thing On Earth, Study Says

CBS Local — There’s a theory that cockroaches would be able to survive a nuclear explosion, but they aren’t the species that scientists say will be the last to survive on earth. Researchers from Oxford University and Harvard University declared that tardigrades would likely be the last surviving species on Earth. The tardigrade is an eight-legged microscopic water animal that reaches just half a millimeter in size. They are referred to as a “water bear”, can survive temperatures of 300 degrees Fahrenheit, and can go 30 years without food or drink. Researchers say they can even outlive the sun.

“A lot of previous work has focused on ‘doomsday’ scenarios on Earth – astrophysical events like supernovae that could wipe out the human race,” said lead author David Sloan, via Oxford. “Our study instead considered the hardiest species – the tardigrade. As we are now entering a stage of astronomy where we have seen exoplanets and are hoping to soon perform spectroscopy, looking for signatures of life, we should try to see just how fragile the hardiest life is.” Researchers conclude that essentially the only way to eliminate tardigrades is through oceans boiling up. This gives them hope that, maybe, similarly resilient life on Mars exists. “Tardigrades are as close to indestructible as it gets on Earth, but it is possible that there are other resilient species examples elsewhere in the universe,” said co-author Rafael Alves Batista. “In this context there is a real case for looking for life on Mars and in other areas of the solar system in general. If tardigrades are Earth’s most resilient species, who knows what else is out there.”

First Half Of 2017 Ranks 2nd Hottest Globally, Behind 2016

WASHINGTON (AP) — The first half of 2017 was the second warmest on record for Earth, only behind last year. The National Oceanic and Atmospheric Administration announced Tuesday Earth’s average temperature from January to June was 57.9 degrees (14.4 degrees Celsius). That’s 1.6 degrees warmer than the 20th century average. Natural El Ninos spike global temperatures. But NOAA climate scientist Ahira Sanchez-Lugo says it is remarkable that 2017 without an El Nino so far beats all but the super El Nino year of 2016. • ALSO READ: California Legislature Passes Cap-And-Trade Deal She says that’s the world changing into an ever warming climate. Record warmth was measured in much of Mexico, western Europe, eastern Russia, eastern Africa and eastern China. The U.S. had its second warmest start. Globally, June was the third warmest on record.
