The Big Picture has two recent sets of photos of geological interest: volcanic activity and images of the earth and space from NASA. You should check out both sets - the volcano pictures, especially, are terrific.

The NOAA, National Climate Data Center has released the global summary of temperatures this summer. It was the hottest June-August period on record, and August was also the hottest on record globally. Ocean temperatures were also hottest on record. NASA, and the Japanese Metr.

NASA posted this map of the temperature anomalies over North America for July, and you can easily see why we there is so much wildfire activity in the U.S. West and Canada North. This is why dense smoke is travelling thousands of miles to the Eastern Seaboard. The heat out west has now pushed much of California into Exceptional Drought”

Solving the Mysteries of Carbon Dioxide 

State of the Planet [2014-07-31 02:38:15]  recommend  recommend this post  (59 visits) info
About 50 percent of the CO2 produced by human activity remains in the atmosphere, warming the planet. But scientists don’t know where and how oceans and plants have absorbed the rest of the manmade CO2. To try to answer these questions, on July 2, 2014, NASA launched the $468 million Orbiting Carbon Observatory-2 (OCO-2), its first Earth remote sensing satellite dedicated to studying atmospheric carbon dioxide from

“Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.” Quote and Image from NASA. Related: What is a

Frying Pan Shoals off the North Carolina coast caught a gust to 99 mph on their weather station. They were in the eye-wall of Hurricane Arthur at the time. Here on the Delmarva Peninsula there is a real risk of extreme rip currents behind the storm. With thousands of folks streaming to the Maryland and Delaware beaches for the holiday weekend, this is a serious threat. Something to think about:

On the Planetary Society  website, the normally responsible and pro-science Planetary Society has posted an opinion piece by Louis Freedman and Tom Jones asking NASA to reconsider its refusal to fund the Asteroid Redirect Mission.  In short, this is a mission to kidnap a small asteroid from elsewhere in the inner solar system, and redirect it towards the earth, hopefully parking it in the

Has The Solar Cycle Peaked? NASA Says Probably. 

Dan\'s Wild Wild Science Journal [2014-06-11 02:35:32]  recommend  recommend this post  (32 visits) info
The 11 year solar cycle has apparently peaked, but it has been one of the weakest solar maxes of the modern era. The cycle is actually 22 years because at the end of 11 years, the sun’s magnetic field flips, and then flips again 11 years later. NASA has a video out today that explains more, and it’s important to note that some of the biggest solar storms can occur

I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece
