Petermann Gletscher Thawing and Thinning

by Andreas Muenchow in Icy Seas

Greenland’s tidewater glaciers are losing mass, through thinning and retreat, at an increasing rate. Greenland’s glaciers located north of 78 North latitude often end in ice shelves, floating extensions of the glaciers extending up to several tens of km into … Continue reading →... Read more »

Heat drives Pakistani migration

by Andy Extance in Simple Climate

As floods don’t impact farming income like high temperatures does, according to Valerie Mueller from the International Food Policy Research Institute (IFPRI) in Washington DC and her colleagues, perhaps some aid money should go to developing more heat-resistant crops to prepare for further climate change. ...

Formation of Nares Strait Ice Bridges in 2014

by Andreas Muenchow in Icy Seas

Darkness and cold covers North Greenland, Ellesmere Island as well as Nares Strait, the waterway that connects these two inhospitable places. And despite the darkness of the polar night, I can see that three beautiful arches made of ice connect … Continue reading →... Read more »

We Discovered Too Late That Tortoises Are Expert Landscapers

by Elizabeth Preston in Inkfish

Countless biology students have dutifully learned to associate the Galapagos Islands with finches. Here Darwin noticed that birds on different islands had different beak shapes, and ta-da, theory of evolution. But galápago is Spanish for “tortoise,” and young Darwin also learned from watching these huge reptiles lumber across the archipelago. Today, the galápagos are only a fraction […]The post We Discovered Too Late That Tortoises Are Expert Landscapers appeared first on I........ Read more »

Planners must be alert to CO2 impact on water supplies

by Andy Extance in Simple Climate

From droughts to deluges, meeting climate targets will make it easier for planners to cope with changes in river flows, says the University of Reading’s Nigel Arnell, though even then we must watch global warming’s impacts keenly. ... Read more »

Study Measures Turbulence Dissipation Rates of Wind Turbines

by dailyfusion in The Daily Fusion

Researchers at the University of Colorado Boulder have performed the first direct measurements of turbulence dissipation rates of wind turbines in real-world conditions. Wake turbulence might dissipate faster than commonly thought and in ways existing weather models do not reflect, their study suggests.... Read more »

“Predicting pre-Columbian anthropogenic soils in Amazonia”

by Umberto in Up and Down in Moxos

“Predicting pre-Columbian anthropogenic soils in Amazonia” is the title of a recent paper by McMichael et al. published in Proceeding of the Royal Society B. It is not open access but you can read the abstract here. In this paper McMichael et al. present a predictive model for the presence of Terra Preta in Amazonia.  The model predicts the likelihood of finding Terra Preta sites in any given spot within Amazonia.  In general, I liked the idea behind the paper. These models gi........ Read more »

Lake Waiau

by Olga Vovk in Milchstraße

Lake Waiau at the top of Mauna Kea is shrinking. For some unknown reasons, for the last few years the lake has shrunk significantly and in September 2013 its diameter was only 15 m. In early 2010, the lake surface area began to shrink rapidly and, by late September 2013, had declined to just 115 m^2 (0.03 acres) – that is, about 2% of its normal surface area. ... Read more »

Sun is not to blame for major changes in weather / Related Research Suggestion

by Usman Paracha in SayPeople

Main Point:

Scientists have found that heat from our Sun is not the major factor in climate changes on Northern Hemisphere.

Published in:

Nature Geoscience

Study Further:

Previously, we thought that periodic changes in solar activity may result in lengthy warm and cold weather on Earth.

In the present study, scientists worked on the causes of climate change in the northern hemisphere over the time of past 10 centuries using the records of temperatures in that time developed wit........ Read more »
