The number of snow cover days in the Alps could halve by the end of the century due to higher temperatures if greenhouse gas emissions remain high, according to new research published today in the European Geosciences Union journal Hydrology and Earth Sciences.
The European Geosciences Union and our publishing partner Copernicus are announcing sweeping new changes, that will give our authors the ability to make vital alterations to their names in previously published scientific literature. This will allow researchers to change their name for several reasons, from a need by transgender authors to change their first name to affirm their gender, to a change in marital status, to cultural name changes, or any other reason.
Researchers use computer simulations to show that extreme weather phenomena can be controlled and modified by making small adjustments to variables in the weather system. The study’s findings promise multiple future applications where weather events can be better controlled, including the effects of climate change.
The Union is gravely concerned by the recent invasion of Ukraine, and hopes for a swift and peaceful resolution, achieved through co-operation and negotiation, rather than aggression.
Professor Chris King, chair of EGU’s Education Committee and a champion of geoscience education, died late last week.
In most of the investigations on metastable systems, the stochastic forcing is modulated by Gaussian noise. Lévy noise laws, which describe jump processes, have recently received a lot of attention, but much less is known. We study stochastic versions of the Ghil–Sellers energy balance model, and we highlight the fundamental difference between how transitions are performed between the competing warm and snowball states, depending on whether Gaussian or Lévy noise acts as forcing.
Simulations are presented investigating the influence of moderately absorbing aerosol in the stratosphere to combat the impacts of climate change. A number of detrimental impacts are noted compared to sulfate aerosol, including (i) reduced cooling efficiency, (ii) increased deficits in global precipitation, (iii) delays in the recovery of the stratospheric ozone hole, and (iv) disruption of the stratospheric circulation and the wintertime storm tracks that impact European precipitation.
In oceanic waters, the accumulation of phytoplankton biomass in winter, when light still limits growth, is attributed to a decrease in grazing as the mixed layer deepens. However, in coastal areas, it is not clear whether winter biomass can accumulate without this deepening. Using 21 years of weekly data, we found that in the Scottish coastal North Sea, the seasonal increase in light availability triggers the accumulation of phytoplankton biomass in winter, when light limitation is strongest.
Climate change is not a new phenomenon. Nor is global warming. So why do researchers report a poor public understanding of this subject around the world? According to a recently published study, 70% of the people surveyed said they were concerned about rising global temperatures but had little knowledge about the climate crisis. When asked how much they knew about the origin and effects of global warming, a whopping 43% admitted they knew only “little.” This imbalance between public awareness …
Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface. In this week’s blog, I will discuss how lubrication theory from hydrodynamics can give us important insights in those aforementioned subduction zone processes. Basic premise of subduction …
A charred pine cone lies on the ground of a mixed beech-pine forest following a forest fire in the Rax-Schneeberg region of Austria in 2021. The charred pine cone and litter are surrounded by unburned yellow beech leaves that fell to the ground after the surface fire. Pyrogenic carbon such as the charred pine cone can remain stable in the environment for extended periods of time and can affect biogeochemical processes in fire-affected soils by altering pH, redox conditions, and …
