Is there really still a chance for staying below 1.5 °C global warming?

RealClimate | 22 September, 2017
There has been a bit of excitement and confusion this week about a new paper in Nature Geoscience, claiming that we can still limit global warming to below 1.5 °C above preindustrial temperatures, whilst emitting another ~800 Gigatons of carbon dioxide. That's much more than previously thought, so how come? And while that sounds like very welcome good news, is it true? Here's the key points.

GeoSciences Column: Catch of the day – what seabirds can tell us about the marine environment

EGU Geolog | 22 September, 2017
Off the coast of Germany, a male northern gannet (for ease, we'll call him Pete) soars above the cold waters of the North Sea. He's on the hunt for a shoal of fish. Some 40km due south east, Pete's mate and chick await, patiently, for him to return to the nest with a belly full of food.

Wooster’s Fossils of the Week: Chaetetids from the Upper Carboniferous of Liaoning Province, North China

Wooster Geologists | 22 September, 2017
Last week's fossil was a chaetetid, introducing the group. They are hyper-calcified demosponges, and the classification of the fossil forms is still not clear. Their value for paleoecological studies, though, is clear. This particular chaetetid from the Benxi Formation preferred a shallow, warm, carbonate environment, and it was part of a diverse community of corals, fusulinids, foraminiferans, brachiopods, crinoids, bryozoans, gastropods, and algae. Such hard substrate communities are not well known in the Carboniferous, and this is one of the best.

Landslides from the Kaikoura earthquake part 5 – other valley-blocking slips

The Landslide Blog | 21 September, 2017
In addition to the large valley-blocking slips that I featured in my earlier posts in this series, the Kaikoura Earthquake triggered many other valley-blocking landslides.  Most of these were of a medium size, and breached soon after the earthquake without causing any major issues.  This is a very spectacular example:-

Cypria lacrima: A new species of Candonid Ostracod from Hays County, Texas.

Sciency Thoughts | 21 September, 2017
Ostracods are small Crustaceans with a bivalved body plan; their body is sandwiched laterally between two large valves, with the animal using its legs to generate a current through the shell, enabling it to feed, and in many cases swim (check). Ostracods are small (seldom much over a millimetre) and can be very abundant, making them common fossils in many deposits. They also often have distinctive shell ornamentation, enabling the identification of species from valves alone, and are both fast-evolving and sensitive to a range of environmental conditions, making them useful in both biostratigraphy (dating rocks using fossils) and palaeoenvironmental reconstruction. The Candonidae are a widespread family of predominantly freshwater Ostracods, being particularly numerous in Eurasia. This group is split into three subfamilies, the marine Paracypridinae and the freshwater Candoninae and Cyclocypridinae, with the Cyclocypridinae being distinguished by swimming setae on second antenna and segmented clasping organs, which the Candoninae lack.
