Having a Rough Winter? Here it is ... From Space

Yes, its been a snowy, icy winter in parts of the US, Canada and Europe and these satellite images look about as miserable as it's felt for some of us. And no, those aren't icicles hanging off the coast of Maine and Nova Scotia; those are called 'cloud streets,' which are long parallel bands of cumulus clouds that form when cold air blows over warmer waters (like the ocean) and a warmer air layer (temperature inversion) rests over the top of both.

But don't let the recent cold weather and snow fool you. The Earth as a whole continues to warm, and

NASA and NOAA announced today

that their analysis puts 2014 as Earth's warmest year since 1880. 2014 was the 38th straight year with above average global annual temperatures, and December 2014 was the hottest December on record. Additionally, 6 of the 12 months last year set heat records. Even though you might feel cold right now, the last time there was a monthly average global temperatures that set a record for cold was in 1916.

OK, now back to the regularly scheduled feeling sorry for ourselves for the recent cold, snowy weather... see more satellite images below.

Nancy Atkinson is a space journalist and author with a passion for telling the stories of people involved in space exploration and astronomy. She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
