For years, geologists have argued about the processes that formed steep inner gorges in the broad glacial valleys of the Swiss Alps. Read more at sciencedaily.com.
A team of scientists, led by biogeochemists at the University of California, Riverside, has found new evidence linking "Snowball Earth" glacial events to the rise of early animals. Read more at sciencedaily.com.
Recently, the head of the United Nations Intergovernmental Panel on Climate Change (IPCC) made public statements in defense of the agency's research associated with rising sea level estimates. Read more at discovery.com.
Lonnie Thompson spent years preparing for his expedition to the remote, mist-shrouded mountains of eastern Indonesia, hoping to chronicle the affect of global warming on the last remaining glacier in the Pacific. He's worried he got there too late. Read more at kval.com.
Climate scientists have long suspected that these glacial cycles are triggered by changes in our planet's orbit. Yet while this theory has had many successes, it fails to explain one critical fact: why the ice ages end every 100,000 years or so, newscientist.com writes.
Primitive humans, trekking across vast expanses of ice in a desperate search to find food. That's the image that comes to mind when most of us think about an ice age. But in fact there have been many ice ages, most of them long before humans made their first appearance. Read more at newscientist.com.
Geoengineering has gained a foothold in the climate change discussion. But before effective action can be taken, the Earth's natural biogeochemical cycles must be better understood, sciencedaily.com writes.
Global warming will likely lead to dramatic poleward shifts of Earth's wettest storm-laden weather patterns, according to a remarkable 56,000-year-old stalactite found in a New Mexican cave, discovery.com says.
In November 2009, an international team of 34 scientists and 92 support staff on board the scientific drilling vessel JOIDES Resolution (JR) were at work investigating sea-level change in a region called the Canterbury Basin, nsf.gov says.
Midt under siste istid smeltet enorme isdekker. Landområder som hadde vært presset ned av isen ble oversvømt. Havet steg svært raskt. I noen av de store elvedalene i Nordvest-Russland nådde havet 200-300 kilometer lenger inn i landet enn i dag. Det forskning.no som skriver dette.
