SOLAR VARIABILITY AND TERRESTRIAL CLIMATE: A new report issued by the National Research Council, "The Effects of Solar Variability on Earth's Climate," lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet. Get the full story from Science@NASA.

ACTIVE SUNSPOT: Big sunspot AR1654 is crackling with C- and M-class solar flares, and it poses a threat for even stronger eruptions. NOAA forecasters estimate a 5% chance of X-flares today. Solar flare alerts: text, voice.

Flares are illuminating the sunspot's magnetic canopy like flash bulbs at a rock concert; the phenomenon is evident in this 37-hour extreme ultraviolet movie from NASA's Solar Dynamics Observatory:

It was another year of incredible weather extremes globally during 2012. The year featured two of the most expensive weather disasters in world history--Hurricane Sandy and the Great U.S. Drought of 2012, which will both cost more than $50 billion. Thankfully, no disasters had a death toll in excess of 2,000, though the 1,901 people dead or missing due to Super Typhoon Bopha in the Philippines may rank as that nation's 2nd deadliest typhoon ever.

Twenty-six weather disasters costing at least $1 billion occurred globally, according to insurance broker AON Benfield. Eleven billion-dollar weather disasters hit the U.S., a figure exceeded only by the fourteen such disasters in 2011. Nine billion-dollar weather disasters hit China, their highest total in a decade of record-keeping. I present for you, now, the top ten global weather stories of 2012, chosen for their meteorological significance and human and economic impact:

Air and water quality woes persistent

A ruddy turnstone feasts on another dead mullet.

The red tide funk dogging Southwest Florida shores has been persistent as 2012 draws to a close and 2013 opens.

Capt. Phil O'Bannon, executive director of the Boca Grande Mote Marine Laboratory satellite office, said his group will focus on a red tide study this year in addition to other research involving sharks, snook and tarpon.

Snow and strong winds from Gandolf will wind down by Saturday afternoon in the Northern Plains. Additional accumulations should be minor, but gusty winds will continue to contribute to blowing snow and dangerous travel in North Dakota and northwest Minnesota through the morning.

Gandolf brought heavy snow and blizzard conditions in spots from the northern/central Rockies starting on January 9 and then shifted slowly east into the Northern Plains by January 12. Below are some of the storm reports and snow totals from Gandolf:

A moderate but impulsive M-class solar flare measuring M1.2 erupted from big Active Region 1654 on January 11, 2013 at 09:11 UTC. A Coronal Mass Ejection (CME) is expected as ejecta has been observed exiting the blast area.  A Type II and Type IV Radio Emissions were associated with the event. AR 1654 is rotating into more geoeffective position and has beta-gamma magnetic configuration capable of producing more M-class flares. Watch out for this region in the coming days. The event started at 08:43, peaked at 09:11 and ended at 09:17 UTC. *** Space Weather Message Code: ALTTP4 Serial Number: 399 Issue...
