Hydrofracking environmental problems not that different from conventional drilling

Shaded areas indicate some of those major regions producing natural gas in the U.S. In this study, researchers select four U.S. states to study that are located within important shale zones including the famous and prolific shale play – Marcellus. Crude oil production and natural gas withdrawals in the United States have lessened the country’s dependence on foreign oil and provided financial relief to U.S. … Continue reading Hydrofracking environmental problems not that different from conventional drilling

The global impact of wild pigs (Sus scrofa) on terrestrial biodiversity

The International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species is a comprehensive database of over 120,000 species and is a powerful tool to evaluate the threat of invasive species to global biodiversity. Several problematic species have gained global recognition due to comprehensive threat assessments quantifying the threat these species pose to biodiversity using large datasets like the IUCN Red List … Continue reading The global impact of wild pigs (Sus scrofa) on terrestrial biodiversity

East Antarctic summer cooling trends caused by tropical rainfall clusters

(Left) East Antarctic warming associated with an anomalous high pressure (H) excited by the MJO rainfall events in the Indian Ocean. (Right) East Antarctic cooling associated with an anomalous low pressure (L) caused by the MJO rainfall events in the western tropical Pacific. The blue (red) line indicates anomalous atmospheric low (high) pressure at sea level. Our planet is warming due to anthropogenic greenhouse gas … Continue reading East Antarctic summer cooling trends caused by tropical rainfall clusters

Co-benefits of protecting mangroves for biodiversity conservation and carbon storage

The conservation of ecosystems and their biodiversity has numerous co-benefits, both for local societies and for humankind worldwide. While the co-benefit of climate change mitigation through so called blue carbon storage in coastal ecosystems has raised increasing interest in mangroves, the relevance of multifaceted biodiversity as a driver of carbon storage remains unclear. Sediment salinity, taxonomic diversity, functional diversity and functional distinctiveness together explain 69%, … Continue reading Co-benefits of protecting mangroves for biodiversity conservation and carbon storage

Asymmetry in carbon dioxide emissions and removals could skew climate targets: research

Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth’s atmosphere are not equal to the climate changes from deliberate CO2 removals—and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research.Because of the complexity of the Earth’s system, things are not as simple as “one ton of CO2 in, equals … Continue reading Asymmetry in carbon dioxide emissions and removals could skew climate targets: research

Geochemical study confirms cause of end-Permian mass extinction event

The most severe mass extinction event in the past 540 million years eliminated more than 90 percent of Earth’s marine species and 75 percent of terrestrial species. Although scientists had previously hypothesized that the end-Permian mass extinction, which took place 251 million years ago, was triggered by voluminous volcanic eruptions in a region of what is now Siberia, they were not able to explain the … Continue reading Geochemical study confirms cause of end-Permian mass extinction event

Production of basil (Ocimum basilicum L.) under different soilless cultures

The main aim of this paper was to investigate the possibility of growing basil under three soilless systems (aeroponic, hydroponic and peatmoss slab systems). A model was developed to predict the nutrients consumption by basil plants. Shoot and root height, fresh and dry mass of whole plant, nutrients uptake, and oil content were studied during the growth period (after 4 and 7 weeks from transplanting). The … Continue reading Production of basil (Ocimum basilicum L.) under different soilless cultures

Application of uniform design to evaluate the different conditions on the growth of algae Prymnesium parvum

Prymnesium parvum is an environmentally harmful algae and well known for its toxic effects to the fish culture. However, there is a dearth of studies on the growth behavior of P. parvum and information on how the availability of nutrients and environmental factors affect their growth rate. To address this knowledge gap, we used a uniform design approach to quantify the effects of major nutrients … Continue reading Application of uniform design to evaluate the different conditions on the growth of algae Prymnesium parvum

Air quality improved during India lockdown, study shows

The study found that travel and work restrictions imposed early in the pandemic resulted in a significant environmental improvement, due to an abrupt reduction in industrial activities and a major decrease in the use of land and air transport. The international team used data from a range of Earth Observation sensors, including those from the European Space Agency’s Sentinel-5p and NASA’s MODIS sensors, to measure … Continue reading Air quality improved during India lockdown, study shows

Extreme greenhouse effect heated up the young Earth

Very high atmospheric CO2 levels can explain the high temperatures on the still young Earth three to four billion years ago. At the time, our Sun shone with only 70 to 80 percent of its present intensity. Nevertheless, the climate on the young Earth was apparently quite warm because there was hardly any glacial ice. This phenomenon is known as the ‘paradox of the young … Continue reading Extreme greenhouse effect heated up the young Earth
