One of the greatest things about this blog and all of you who follow, is that I get to learn so much about you and the part of the country that you live in. I’ve never been so blessed by anything in my life as I have with this motorcycle and the people and places it brings me. «Read the rest of this article» Sections: Commentary | No Comments
NASA reports Arctic Winter Sea Ice Extent second lowest on recordWritten by Maria-José Viñas
On March 17th, the Arctic sea ice cover peaked at 5.59 million square miles (14.48 million square kilometers), making it the second lowest maximum on record, at about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached on March 7th, 2017. ![]() On March 17th, the Arctic sea ice cover peaked at 5.59 million square miles (14.48 million square kilometers), making it the second lowest maximum on record.

NASA’s Soil Moisture Active Passive (SMAP) gets ready to monitor soil’s freeze, thaw cyclesWritten by Alan Buis
But the changing date of the spring thaw has consequences far beyond reducing the number of mornings when you have to scrape off your windshield. One ecosystem where scientists would most like to understand the effects of changing freeze/thaw cycles is boreal forests, the great ring of green covering the land nearest the North Pole. ![]() SMAP will monitor the frozen or thawed state of the global landscape north of 45 degrees north latitude.

NASA Earth Scientists to study Arctic Sea Ice losses effects on Clouds, Weather, Global WarmingWritten by Tony Phillips
“Polar regions are important for us to study right now,” explains Tom Wagner of NASA’s Earth Science Division in Washington DC. “They are changing rapidly.” One of the most visible of signs of warming is the retreat of Arctic sea ice. Every year, sea ice waxes and wanes in a normal response to the changing of seasons; the annual sea ice minimum occurs near the end of northern summer. Since the 1970s, researchers carefully watched to see if the rhythm of Arctic sea ice would respond to global warming. «Read the rest of this article» Sections: Technology | No Comments
NASA’s WISE, Spitzer space telescopes discover Brown Dwarf system close byWritten by Whitney Clavin
Images from the space telescopes also pinpointed the object’s distance to 7.2 light-years away, earning it the title for fourth closest system to our sun. The closest system, a trio of stars, is Alpha Centauri, at about 4 light-years away. ![]() This artist’s conception shows the object named WISE J085510.83-071442.5, the coldest known brown dwarf. Brown dwarfs are dim star-like bodies that lack the mass to burn nuclear fuel as stars do. «Read the rest of this article» Sections: Technology | No Comments
NASA’s AIM spacecraft data shows Teleconnections in Earth’s Atmosphere linking Climate and Weather across the GlobeWritten by Tony Phillips
Turns out, that’s not so far apart. New data from NASA’s AIM spacecraft have revealed “teleconnections” in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again, linking weather and climate more closely than simple geography would suggest. «Read the rest of this article» Sections: Technology | No Comments

International Space Station Flys Through a Geomagnetic StormWritten by Dr. Tony Phillips
It might be the greatest show in Earth orbit, too. High above our planet, astronauts onboard the International Space Station (ISS) have been enjoying an up-close view of auroras outside their windows as the ISS flys through geomagnetic storms. We can actually fly into the auroras,” says eye-witness Don Pettit, a Flight Engineer for ISS Expedition 30. “It’s like being shrunk down and put inside of a neon sign.” «Read the rest of this article» Sections: Technology | No Comments
Europe Hammered by Winter, Is North America Next?Written by Dauna Coulter
Then, out of the blue, Europe got clobbered: Over the past two weeks, temperatures in Eastern Europe have nose-dived to -30 degrees Celsius (-22 degrees Fahrenheit). Blizzards and the bone-chilling cold have resulted in the deaths of over 550 people so far, with rooftop-high snow drifts trapping tens of thousands of villagers in their homes and cutting off access to entire towns. It has even snowed as far south as North Africa. ![]() This map shows temperature anomalies for Europe and western Russia from January 25th to February 1st, 2012, compared to temperatures for the same dates from 2001 to 2011. The anomalies are based on land surface temperatures observed by the MODIS instrument on NASA’s Terra satellite. «Read the rest of this article» Sections: News | No Comments
What Happened to all the Snow?Written by Dauna Coulter
Here’s a prime example. “The Mammoth Mountain ski resort in the Sierras of California got more than 200 inches of snow last December,” says NASA climatologist Bill Patzert of the Jet Propulsion Laboratory. “This December they got less than 10 inches.” Temperatures have flip-flopped too. There were 583 new heat records broken in the first five days of January in the US. ![]() (left) Effects of the positive phase of the arctic oscillation; (right) effects of the negative phase of the arctic oscillation (Figures courtesy of J.
