Clarksville, TN – The winter months have always been my least favorite time of the year. Obviously when I was a kid, I loved the snow and all that came with it, but as an adult, a biker, and a man who has a few “achy” bones, winter is NOT fun for me.
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.

Washington, D.C. – Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.
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.

Pasadena, CA – Those who feel as though they’ve been living in the never-ending winter of the movie “Frozen” this year may be glad to hear that the spring thaw is now typically arriving up to two weeks earlier in the Northern Hemisphere than it did 20 to 30 years ago.
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.

Washington, D.C. – Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place in particular–the Arctic.
“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.

Pasadena, CA – NASA’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest “brown dwarf” known — a dim, star-like body that surprisingly is as frosty as Earth’s North Pole.
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.
NASA’s AIM spacecraft data shows Teleconnections in Earth’s Atmosphere linking Climate and Weather across the Globe

Washington, D.C. – Earth’s poles are separated by four oceans, six continents and more than 12,000 nautical miles.
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.

Washington, D.C. – Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold. Longtime sky watchers say it is the greatest show on Earth.
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.”

Pasadena, CA – For the first half of this year’s winter, the big news was warm temperatures and lack of snow. Ski resorts were covered in bare dirt, while January temperatures in southern California topped July highs.
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.

Washington, D.C. – Winter seems to be on hold this year in some parts of the United States. Snowfall has been scarce so far in places that were overwhelmed with the white stuff by the same time last year.
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.
