“Knowing what a chicken looks like and what all the chickens before it looked like doesn’t help us to understand the egg,” says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and the early history of the Earth. The Earth’s lithosphere is divided into several plates that are in constant motion, and today’s geologists […]

Scientists from the University of Delaware’s Bartol Research Institute in the Department of Physics and Astronomy have discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. The gamma rays observed by the team have energies more than a trillion times higher than the energy of visible light […]

Buried deep in the Antarctic ice, an observatory has spotted ghostly, nearly massless particles coming from inside our galaxy and points beyond the Milky Way. Finding these cosmic neutrinos not only confirms their existence but also sheds light on the origins of cosmic rays, the researchers said. The IceCube Neutrino Observatory is made up of 86 shafts dug 8,000 feet […]

Ghana is being pressured to sell out it’s global agribusiness. The U.S. and the global seed industry are trying to strong-arm Ghana into adopting the International Convention for the Protection of New Varieties of Plants, known as UPOV. The treaty confers intellectual property rights on huge seed companies such as Monsanto and locks farmers into a limited selection of […]

According to National Geographic, the coldest place on Earth is the East Antarctic Ice Sheet with temperatures as low as minus 144 degrees Fahrenheit. The temperature reading was taken during the polar winter and is the lowest temperature ever recorded on the Earth. Russia’s Vostok Weather Station previously held the record for the lowest recorded temperature. However, that record has […]

Geologists are convinced that humans have left a mark upon the planet that will detectable millions of years from now. Long after human civilization has perished, there could be a stratum of fossilized rock and a geological time zone that says: “We were here.” So there is a case for calling the present epoch “the Anthropocene” − probably dating from […]

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

The monster forest fires rampaging across the Western states may soon be the norm, thanks to climate change. New research indicates that as rainfall diminishes and vegetation dries out on a warmer planet, the West is headed into a more fire-prone future,” wildfire specialist Max Moritz tells the Los Angeles Times. After studying satellite imaging of fires and data from […]

The continued melting of the West Antarctic ice sheet is progressing faster than expected, and the resulting rise in sea levels will have a global impact.The stark new findings point to a potential sea-level rise of up to 10 feet or more in the coming centuries. This increase in the global sea-level will threaten many major cities, including New York, […]

Western Antarctica is heating up faster than almost any other region on earth, increasing the risk that a huge ice sheet there could collapse and cause a drastic rise in sea levels. That’s the alarming conclusion of climate researchers who used data from a remote weather station combined with other temperature readings on the continent to show that West Antarctica […]
