In a new study, researchers led by Peak identify a likely cause for the missing rocks: the breakup of Earth's ancient supercontinent Rodinia approximately 700 million years ago. The upheaval was so violent it likely washed rocks and sediment into the ocean — one billion year's worth, in the case of the Grand Canyon.
Ice provides historical records about climate and shows the impact humanity has had. But many glaciers are now melting, prompting renewed urgency among scientists.
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geophysical Research Letters that, as glacial ice from Greenland, Antarctica, and the Arctic Islands melts, Earth's crust beneath these land masses warps, an impact that can be measured hundreds and perhaps thousands of miles away.
While the rest of the world sizzled, the South Pole shivered with an average temperature of minus-78 degrees over the past six months.
In eastern Yemen there is a hole in the ground known as the Well of Barhout, aka the "Well of Hell." Located in the Hadhramaut region, the hole is 30 meters wide and 112 meters deep. According to local reports, the Well of Hell is a prison for demons as indicated by the horrible stench emanating from it. Recently, explorers descended to the bottom of the hole for the first time. Unsurprisingly, the demons hid from the interlopers.
STOCKHOLM, Oct 6 (Reuters) - A cloth sheet used to shield part of the Helags glacier in northern Sweden over the summer saved at least 3.5 metres in height from melting, according to organisers of the private initiative, the first of its kind in Scandinavia.
The study takes a look at earthshine, or the light reflected from the planet that casts a faint light on the surface of the Moon. It’s also known as the Da Vinci Glow, because Leonardo da Vinci was the first person to formally write about it. Research has advanced quite a bit since da Vinci’s writing 500 years ago, and the new findings use two decades of earthshine data collected at Big Bear Solar Observatory using a special type of telescope to view the Moon.
SUSANVILLE, Calif. — One grew to a size larger than Rhode Island and leveled a Gold Rush-era town. Another swelled to a quarter million acres as it came within a few miles of Lake Tahoe. Another burned down 900 buildings and was the first ever to reach a million acres.
In the past two years, California has found itself under siege from more large-scale fires burning with greater intensity than at any time on record.
Global warming has caused extreme ice melting events in Greenland to become more frequent and more intense over the past 40 years according to new research, raising sea levels and flood risk worldwide.
Over the past decade alone, 3.5 trillion tonnes of ice has melted from the surface of the island and flowed downhill into the ocean.
