Deep-rooted and completely erroneous preconceptions of our planet’s arid lands as sterile bit-players in the great game of the earth’s dynamic systems have long inhibited our scientific enthusiasm for, and understanding of, the desert. We are now beginning to
This is NOT a killer asteroid entering the Earth's atmosphere. It is a sun dog over Oak Flat Campground near Superior, Arizona. Oak Flat is going to become a gigantic crater.
Because it won't be a meteor that causes it. It won't be an atomic bomb test. And it won't be because of aliens like those stupid ones in Indiana Jones and the Kingdom of the Crystal Skull. The giant crater will
We are in Georgia gearing up for the second phase of field work for the SUGAR project, which will involve collecting seismic refraction data along two profiles spanning eastern Georgia. In the coming weeks, we’ll deploy thousands of small seismometers along county and state roads across the region, which will record sound waves generated by a series of controlled blasts. We can use the sound waves to make pictures of geology beneath the surface. Geological structures beneath Georgia record [...]
Temperature of the Earth under presentconditions with a solar flux of 341 W/m2,and just before the runaway greenhouse is triggeredfor a mean solar flux of 375 W/m2.From the Leconte et al. article referenced in text.NASA has just released an announcement this morning that the Kepler spacecraft has spotted a planet about 60% bigger than our Earth in a habitable zone of a star "similar to our sun." The planet is dubbed Kepler-452b, and it's about 1400 light years from Earth in the [...]
Forty-six years ago today I set beside my Great Grandmother, who walked to Indian Territory (now Oklahoma) behind a covered wagon, and listened to Armstrong and Aldrin land on the Moon. While the photos of the Moon from the Apollo astronauts were dramatic, it was the pictures they took looking back at Earth that changed the way we think about our planet. Today, we got another one of those photos
Every summer for the past 25 years the AMS publishes the State of the Climate Report in BAMS. I usually curl up in a cool place and read it and you can as well since the AMS has made it free to all to read. this year’s report has plenty of updated (and not good) news about our planet. From NOAA: In 2014, the most essential indicators of Earth’s changing
Disposal of surplus teaching microscopes: £100 eachThe Department of Earth Sciences, University of Oxford has a number of former teaching Swift polarizing microscopes to dispose of. Each microscope has been regularly serviced, with optics cleaned and aligned and annually electrically tested (expires end of June 2015).The cost of each microscope is £100 (collection free, shipping extra).Viewing instruments prior to purchase is recommended. Prior-Swift MP81: sliding analyser and betrand [...]
In an area of Earth that many call the Third Pole region, near the Tibetan Plateau, scientists with the University of Texas and the Chinese Academy of Sciences say that[...]

It seems that at least once a year, news of the “largest dinosaur ever found” makes headlines. That’s
As many as one in five deaths in Bangladesh may be tied to naturally occurring arsenic in the drinking water; it is the epicenter of a worldwide problem that is affecting tens of millions of people. For two decades, health specialists and earth scientists from Columbia University have been trying to understand the problem, and how to solve
'A screaming roller coaster; how fast am I travelling (due to Earth's spin and Earth's orbit)?'
After the class roller-coaster experience, ask your pupils ‘Why were we acting like this?’ The answer is that you are all travelling very fast towards the East - due to the spin of the Earth. If you are on the Equator you are travelling at 1,674.4 km/h. To calculate how fast you’re
In September the ‘Sustainable Development Goals’ will be agreed – an ambitious set of targets, building on the Millennium Development Goals. These goals and associated work plans will set out how the world will work to promote poverty eradication, change unsustainable consumption patterns and facilitate sustained and inclusive economic growth, social development and environmental protection over the next 15 years (2015-2030). Specific goals are likely to include [...]
When the term “World’s Tallest Structure” is mentioned most people immediately think of a “skyscraper” or a tall building. The Burj Khalifa, a skyscraper in Dubai, holds the title of the world’s tallest building with an amazing height of 2717 feet. However, if you consider any structure that extends upwards from Earth’s surface, many deepwater
Here is an Update from NASA late on Saturday night…. New Horizons Team Responds to Spacecraft Anomaly The New Horizons spacecraft experienced an anomaly the afternoon of July 4 that led to a loss of communication with Earth. Communication has since been reestablished and the spacecraft is healthy. The mission operations center at the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, lost contact with the unmanned spacecraft —
If anyone tells you that the warming we’ve seen over the past century is just a natural swing in Earth’s temperature, they are wrong. Absolutely and totally wrong.This widespread myth is a favorite of some politicians, but It’s been proven WRONG, and there is no scientific doubt about it. I’ve talked about this before and shown graphs etc. but Bloomberg Business did an excellent html web page that shows just
Because we know little about hurricane behavior during periods when Earth was warmer or colder than at present, it’s challenging to construct models to predict future trends in hurricane activity as Earth’s climate changes. To remedy this problem, researchers have been working to reconstruct records of hurricane strikes in the
“The greenhouse effect” often gets a bad reputation because of its association with global warming, but the reality is we can not live without it. What causes greenhouse effect? Life on earth depends on the energy of the sun. Approximately 30 percent of the sunlight that beams toward Earth deflected by the outer atmosphere […]

Our sun is a volatile star: explosions of light, energy and solar materials regularly dot its surface. Sometimes an eruption is so large it hurls magnetized material into space, sending out clouds that can pass by Earth's own magnetic fields, where the interactions can affect electronics on satellites, GPS communications or even utility grids on the
