As the U.S. House of Representatives prepares to pass a climate-change bill, the Australian Parliament is preparing to kill its own country's carbon-emissions scheme. Why? A growing number of Australian politicians, scientists and citizens once again doubt the science of human-caused global warming. Among the many reasons President Barack Obama and the Democratic majority are so intent on quickly jamming a cap-and-trade system through Congress is because the global warming tide is again shifting. It turns out Al Gore and the United Nations (with an assist from the media), did a little too vociferous a job smearing anyone who disagreed with them as "deniers." The backlash has brought the scientific debate roaring back to life in Australia, Europe, Japan and even, if less reported, the U.S....

US Rep. Dana Rohrabacher was in a froth, and his audience loved it. The California Republican was talking about global warming and could barely contain his disgust.
a major earthquake centered in the New Madrid seismic zone potentially is one of the most serious natural hazard threats facing the state of Missouri. Experts mostly agree that it is not a matter of if a significant earthquake will occur, but rather it is a matter of how soon one will happen.
Richard Allen has created... a suite of algorithms designed to measure real time seismic data and then rapidly detect the initiation of an earthquake
The quake caused 80 million tons of dirt and trees to slide from the southeast side of the canyon into the Madison River at an estimated 100 miles per hour. The force of the slide displaced both the air in the canyon and the water in the Madison River below and buried the Rock Creek public campground. The slide created a barrier across the Madison River that formed a new lake that still exists today, Quake Lake. All told, twenty-eight people lost their lives in the quake and its aftermath.
While researching this morning's major earthquake off of the coast of Honduras, I came across an interesting story. It was about the fear of a tsunami in Puerto Rico, reported just yesterday. This is on the other side of the Caribbean, but could it be connected? The Tsunami Watch was dropped this morning, but other questions have been raised.

an anomalous layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic tremors... The presence of such a layer in similar settings elsewhere could point to other regions of slow quakes. Slow earthquakes, also called silent earthquakes, take days, weeks, or even months to release pent-up energy instead of seconds or minutes as in normal earthquakes....

What do you do when you have a fossil quarry that has yielded some of the most important and rarest of dinosaur fossils in North America, but the fossil-bearing layer of rock is tilted at 70 degrees and there is so much rock that not even jackhammers can get you to the fossils any longer? ... Over several days these skilled employees, using their expertise with explosives, blew away the rock covering the fossils and exposed a significant amount of the fossil-bearing layer so that excavation can begin again this year. Without their talents, scientifically important fossils would have remained locked underground in their stony mausoleum.....

Having started off in California in 2004, it is now just east of the Rockies, stretching from Montana's border with Canada down past El Paso on the Texas-Mexico border.

The Dynamic Designs Challenge will invite teams of students around the world to take part in a unique competition to design a building for an earthquake zone.
UK's Lord Christopher Monckton, a former science advisor to Prime Minister Margaret Thatcher, claimed House Democrats have refused to allow him to appear alongside former Vice President Al Gore at a high profile global warming hearing on Friday April 24, 2009 at 10am in Washington. Monckton told Climate Depot that the Democrats rescinded his scheduled joint appearance at the House Energy and Commerce hearing on Friday. Monckton said he was informed that he would not be allowed to testify alongside Gore when his plane landed from England Thursday afternoon. "The House Democrats don't want Gore humiliated, so they slammed the door of the Capitol in my face...."
New Madrid appears to be cold and dying. ... thermally New Madrid is surprisingly similar to other areas of the eastern United States.... future earthquakes will occur somewhere else when the New Madrid system "shuts down." Once this happens, it may be a very long time — thousands of years or longer — before New Madrid becomes active again. "Although we don't know when the New Madrid fault system will shut down, it may be dying today,"
Marc Morano does not think global warming is anything to worry about, and he brags about his confrontations with those who do. ... once spotted former Vice President Al Gore on an airplane returning from a climate conference in Bali. Mr. Gore was posing for photos with well-wishers, and Mr. Morano said he had asked if he, too, could have his picture taken with Mr. Gore. He refused, Mr. Morano said. "You attack me all the time," Mr. Gore said... As a spokesman for Senator James M. Inhofe of Oklahoma, the ranking Republican on the Environment and Public Works Committee, Mr. Morano was for years a ceaseless purveyor of the dissenting view on climate change, sending out a blizzard of e-mail to journalists covering the issue....
The president's new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air. John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed.

The progress of the earth sciences and the advancement of technologies associated with the understanding of our planet during the 1940's and 50's have led geologists to develop a new way of looking at the world and how it works. This exhibit explains the history of our new understanding of the Earth and provides a brief overview of the theories behind it.

Alaska Earthquake 1964. 210 photos. 3 resolutions are available.
The 1964 Alaska earthquake, also known as the Great Alaskan Earthquake, the Portage Earthquake and the Good Friday Earthquake, was a megathrust earthquake that began at 5:36 P.M. AST on Good Friday, March 27, 1964. Across south-central Alaska, ground fissures, collapsing buildings, and tsunamis resulting from the earthquake caused about 131 deaths. Lasting nearly four minutes, it was the most powerful recorded earthquake in U.S. and North American history, and the second most powerful ever measured by seismograph. It had a magnitude of 9.2, at the time making it the second largest earthquake in recorded history.
A Spanish-British research project has come up with three future scenarios for the effects of climate change on the Mediterranean over the next 90 years, using global models from the Intergovernmental Panel on Climate Change (IPCC). The conclusions show that ocean temperatures in this area will increase, along with sea levels. [Yeah, sure]
SANTA FE, N.M. — Former astronaut Harrison Schmitt, who walked on the moon and once served New Mexico in the U.S. Senate, doesn't believe that humans are causing global warming.
