Will global warming bring a change in the winds? Dust from the deep sea provides a clue

January 14, 2021 by Zakia

The westerlies – or westerly winds – play an important role in weather and climate both locally and on a global scale, by influencing precipitation patterns, impacting ocean circulation and steering tropical cyclones. So, finding a way to assess how they will change as the climate warms is crucial.

Typically, the westerlies blow from west to east across the planet’s middle latitudes. But scientists have noticed that over the last several decades, these winds are changing, migrating poleward. Research suggests this is because of climate change.

But, scientists have been debating whether the poleward movement of the westerlies will continue as temperatures and atmospheric carbon dioxide (CO2) increase further under future warming scenarios. It’s been difficult to resolve this scientific question because our knowledge of the westerlies in past warm climates has until now been limited.

Modeling rainfall drop by drop

January 2, 2021 by Zakia

Using a network of a newly introduced type of rain gauge that can measure rainfall with drop-by-drop precision, KAUST researchers have developed a high-frequency rainfall model to improve understanding of rainfall/runoff dynamics, such as flash flooding and hydrodynamics in small watersheds.

Rainfall modeling is one of the core aspects of weather forecasting and is often used to predict other weather parameters, such as wind and solar irradiance. Yet the power and insight of such models are limited by the data used to construct them.

When it comes to precipitation, this means that modelers have to rely on sparse recordings of rainfall at 6-15-minute intervals at best, but more often hourly intervals. [Read more…] about Modeling rainfall drop by drop

Researchers compile world’s largest inventory of known plant species

December 5, 2020 by Zakia

Leipzig could mean for the future of plant taxonomy what Greenwich meant for world time until 1972: it could become the reference city for correct scientific plant names.

In an outstanding feat of research, the curator of the Botanical Garden of Leipzig University, Dr Martin Freiberg, and colleagues from iDiv and UL have compiled what is now the largest and most complete list of scientific names of all known plant species in the world.

The Leipzig Catalogue of Vascular Plants (LCVP) enormously updates and expands existing knowledge on the naming of plant species, and could replace The Plant List (TPL) – a catalogue created by the Royal Botanic Gardens, Kew in London which until now has been the most important reference source for plant researchers.

Ecologically friendly agriculture doesn’t compromise crop yields

November 14, 2020 by Zakia

Increasing diversity in crop production benefits biodiversity without compromising crop yields, according to an international study comparing 42,000 examples of diversified and simplified agricultural practices.

Diversification includes practices such as growing multiple crops in rotation, planting flower strips, reducing tillage, adding organic amendments that enrich soil life, and establishing or restoring species-rich habitat in the landscape surrounding the crop field.

“The trend is that we’re simplifying major cropping systems worldwide,” says Giovanni Tamburini at the Swedish University of Agricultural Sciences and lead author of the study. [Read more…] about Ecologically friendly agriculture doesn’t compromise crop yields

Self-watering soil could transform farming

November 4, 2020 by Zakia

A new type of soil created by engineers at The University of Texas at Austin can pull water from the air and distribute it to plants, potentially expanding the map of farmable land around the globe to previously inhospitable places and reducing water use in agriculture at a time of growing droughts.

As published in ACS Materials Letters, the team’s atmospheric water irrigation system uses super-moisture-absorbent gels to capture water from the air.

When the soil is heated to a certain temperature, the gels release the water, making it available to plants. When the soil distributes water, some of it goes back into the air, increasing humidity and making it easier to continue the harvesting cycle.

Declines in shellfish species on rocky seashores match climate-driven changes

October 20, 2020 by Zakia

The waters of the Gulf of Maine are warming faster than oceans almost anywhere on Earth. And as the level of carbon dioxide rises in the atmosphere, it’s absorbed by the oceans, causing pH levels to fall. Ocean acidification makes it difficult for shellfish to thicken their shells – their primary defense against predators.

In a new study in the journal Communications Biology, researchers Peter Petraitis, a retired professor of biology in Penn’s School of Arts & Sciences, and Steve Dudgeon, a biology professor at California State University, Northridge, who completed a postdoctoral fellowship with Petraitis at Penn in the 1990s, show that the changing climate is taking a toll on Maine’s sea life.

A dataset collected over two decades, including numbers of five species of mussels, barnacles, and snails, shows that all have been experiencing declines – some slow, some more rapid – in part owing to climate change.

Soils mission will unite farmers and researchers to end degradation and restore fertility

September 7, 2020 by Zakia Leave a Comment

Soil is an abundant yet underrated asset that is rapidly degrading. Now Europe wants to save this neglected resource, with the upcoming Horizon Europe mission aiming for a 100 per cent increase in healthy soils by 2030.

The mission is one of Europe’s five research ‘moonshots’ set to launch in 2021. It is “maybe the most difficult one,” said Teresa Pinto Correia, professor at the University of Évora. “Other [missions] are on topics which people know about.”

Pinto Correia is one of fifteen members of the soils mission board that is drawing up plans for the mission in the EU’s next research programme, Horizon Europe. [Read more…] about Soils mission will unite farmers and researchers to end degradation and restore fertility

Fossil trees on Peru’s Central Andean Plateau tell a tale of dramatic environmental change

September 1, 2020 by Zakia

On an expedition to the Central Andean Plateau, researchers from the Smithsonian Tropical Research Institute (STRI) and colleagues were astounded to find a huge fossil-tree buried in the cold, grassy plain. The plant fossil record from this high-altitude site in southern Peru contains dramatic reminders that the environment in the Andes mountains changed drastically during the past 10 million years, but not in the ways that climate models of the past suggest. Findings from the expedition are presented in the journal Science Advances.

“This tree and the hundreds of fossil wood, leaf and pollen samples we collected on the expedition, reveal that when these plants were alive the ecosystem was more humid–even more humid than climate models of the past predicted,” said Camila Martinez, a fellow at STRI, who recently finished her doctorate at Cornell University. “There is probably no comparable modern ecosystem, because temperatures were higher when these fossils were deposited 10 million years ago.”

The anatomy of the petrified (permineralized) wood the researchers found is very much like wood anatomy in low-elevation tropical forests today. Indeed, the altitude then was probably only 2,000 meters above sea level.

But that ecosystem did not last for long. Today, the arid, intermountain plateau lies at 4,000 meters above sea level.

Five million year-old fossils from the same sites confirmed that the Puna ecosystem that now dominates the Andes’ high mountain plateaus had been born: the younger pollen samples were mostly from grasses and herbs, rather than from trees. Leaf material was from ferns, herbs and shrubs, indicating that the plateau had already risen to its current altitude.

“The fossil record in the region tells us two things: both the altitude and the vegetation changed dramatically over a relatively short period of time, supporting a hypothesis that suggests the tectonic uplift of this region occurred in rapid pulses,” said Carlos Jaramillo, STRI staff scientist and project leader.

“Andean uplift played an important role in shaping the climate of South America, but the relationship between the rise of the Andes, local climates and vegetation is still not well understood,” Martinez said. “By the end of this century, changes in temperature and atmospheric carbon dioxide concentrations will again approximate the conditions 10 million years ago. Understanding the discrepancies between climate models and data based on the fossil record help us to elucidate the driving forces controlling the current climate of the Altiplano, and, ultimately, the climate across the South American continent.
