NASA finds dirty glaciers in Alaska – may melt faster

Over the years, scientists have captured spectacular photographs while mapping ice during NASA’s Operation IceBridge mission. Many of the photographs have featured the icy landscapes of Greenland and Antarctica, over which lengthy missions are flown each year over. But the views during shorter duration IceBridge missions over Alaska reveal some equally majestic icescapes. Chris Larsen of the…

Recycled science: Reflective surfaces alleviate heatwaves

From ETH ZURICH and the “obvious science” department comes this study that is little more than a recycle of what is already understood about crops and “shininess”, back in 2009 – reflective surfaces absorb less heat during the daytime. Just wait till the greens deal with GMO engineered “reflective corn”, they’ll have a head-exploding dilemma. Climate…

Settled Science: Clusters of small satellites could help estimate Earth's reflected energy

From M.I.T. and the “Total outgoing radiation is actually one of the biggest uncertainties in climate change” department: Batches of shoebox-sized satellites could improve estimates of Earth’s reflected energy A team of small, shoebox-sized satellites, flying in formation around the Earth, could estimate the planet’s reflected energy with twice the accuracy of traditional monolith satellites,…

The Size of Icy Reflections

Guest Post by Willis Eschenbach In my continuing wanderings through the regions cryospherical, I find more side roads than main highways. In my last two posts here and here, I discussed the curious inverse relationship between temperature and ice accumulation rates in Greenland and Antarctica. Wanting to understand the changes in the polar oceans that occur when…
