In the 1960s, scientists anticipated a `New Ice Age`. Later, they warned of humans triggering a ‘Nuclear Winter’. Now, it’s ‘Global Warming’. Why this change in emphasis? And why did it take 100 years for the theory behind ‘Global Warming’ to take hold?
New research by scientists from the University of Gloucestershire indicates that a remarkable combination of circumstances sparked widespread scientific interest in ‘Global Warming’ in the later decades of the 20th Century.
For years scientists have been studying the impact of different geophysical fields on the earthquakes occurrence. It has been assumed that the fields, generated due to the solar activity, earth flows fluctuations, the Earth`s speed of rotation and even the launch of magnetohydrodynamic generators affect the strained state of the earth`s crust, these fields `pumping` additional energy into the crust. Normally the aroused earthquakes are recorded several days after the provoking key event.
Knee-high relative of Triceratops unearthed.
The fearsome horns and bony neck plates of Triceratops have scared generations of kids. Now fossil finds reveal that its predecessor was a little more huggable: it was a dog-sized creature with a beak.
Triceratops is the most famous member of the late ceratopsians, which were rhinoceros-like dinosaurs with horns. Little is known about the early evolution of this large and varied group of plant-eaters because their fo
Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years.
Earlier this month Ted Scambos of the University of Colorado alerted BAS glaciologists David Vaughan and Chris Doake to images from the NASA MODIS satellite. Meanwhile, in Antar
Deserts covered Central Asia as early as 22 million years ago
The great Asian deserts developed 22 million years ago at the latest, 14 million years earlier than had been thought. So concludes a new analysis of Chinese soils, filling in another piece of the puzzle of the Himalayas’ birth.
Today, huge deserts characterize the vast landmasses inside Asia, the largest continent on Earth. Here, cut off by the Himalayas from the humidity of the Indian Ocean and far from any othe
Blue jets connect Earth’s electric circuit.
Video images captured in Puerto Rico suggest that blue flashes of light, much like lightning, feed energy from thunderstorms up into the Earth’s ionosphere – a blanket of electrically charged air some 70 kilometres above the ground 1 .
Some researchers suspect that such phenomena may also fix nitrogen for plants to use and interact with the ozone layer 2 .
The images, taken in September 2001
