Greenland's pronounced glacier retreat not irreversible

Via the AGU weekly highlights: In recent decades, the combined forces of climate warming and short-term variability have forced the massive glaciers that blanket Greenland into retreat, with some scientists…

New paper speculates on volcanoes during the Little Ice Age

From NCAR/UCAR, they’re still trying to stamp out solar influence as a potential cause of the Little Ice Age. One of the things I wonder about is that during low…

"We need more hurricanes to save the coral reefs"

Above: SST heat loss from Hurricane Irene The title is sarcasm, but it does present an interesting quandary for alarmists. What’s more acceptable – hurricanes and the loss of life…

Study: Getting the S out of jet fuel may cool the climate

This study from Yale University  seems contradictory to what we know about aerosols. Generally more aerosols like SO2 cool the climate, but in this case they are saying “it’s offset…

Possible earthquake early warning signal discovered

From the AGU: An atmospheric precursor to the recent Japan megaquake Most scientists believe that earthquakes are inherently unpredictable, and reports of various kinds of earthquake precursor signals have been…

Getting GRLed

Bill Illis: Clouds account for most of the variability in net radiation at the Top of the Atmosphere

While we are marveling at the recent revelation out of Serbia that shows a connection between cosmic rays, clouds and temperature, our own volunteer moderator, Roger (Tallbloke) noticed and collated…

What do sea measurements reveal about Earth's temperature trend?

From the AGU highlights Despite the fact that average temperatures on land have been increasing from year to year, globally averaged surface temperatures from 2000 to 2010 have shown only…

Overpeck says 3 feet, real world sea level data says no way

From high and dry  University of Arizona, home of the world famous parking lot USHCN weather station, we have word via Eurekalert that a simulation says it will be bad…

Ionospheric airglow signature of tsunami waves confirmed

From the University of Illinois, something quite interesting, long speculated on, now confirmed. Tsunami airglow signature could lead to early detection system Researchers at the University of Illinois have become…

Contrails – itty bitty icy forcing

From the American Geophysical Union weekly highlights: Estimating climate effects of contrails Condensation trails, or so-called contrails, formed by freezing of ice crystals in the exhaust from aircraft jet engines…

Clouds, radiative forcing, and climate models – still tweaking

As most readers know, clouds are still poorly understood and under-represented in climate models. This new research may help. From: DOE/Pacific Northwest National Laboratory Effect of cloud-scattered sunlight on earth’s…

Final words on the 2010 Russian heat wave from AGU: weather, predictable

The map above, from the NASA Earth Observatory Picture of the Day website, shows how the temperature on July 27 departed from the 2000 to 2008 average. Download large image (1…

Yellowstone's supervolcano – worse than we thought

Icelandic volcano exonerated for harsh winter of 1783–1784

From AGU’s Geophysical Research Letters:   In June 1783 the Laki volcano in Iceland began to erupt, and continued erupting for months, causing a major environmental disaster. The eruption spewed…

The minimal solar activity in 2008–2009 and its implications for long‐term climate modeling
