One county in Texas has issued a voluntary evacuation notice for some residents, as Hurricane Beryl hurtles towards the state.
The Category 4 storm that has killed at least seven people in the Caribbean, according to the Associated Press’ latest death toll, is forecast to hit Texas by this weekend.
RPTU University of Kaiserslautern-Landau has shown for the first time, in a joint study with BOKU University, that permaculture brings about a significant improvement in biodiversity, soil quality and carbon storage.
In view of the challenges of climate change and species extinction, this type of agriculture proved to be a real alternative to conventional cultivation—and reconcile environmental protection and high yields.
Permaculture uses natural cycles and ecosystems as blueprint. Food is produced in an agricultural ecosystem that is as self-regulating, natural and diverse as possible. For example, livestock farming is integrated into the cultivation of crops or the diversity of beneficial organisms is promoted in order to avoid the use of mineral fertilizers or pesticides.
Scientists have found three new species that are close relatives to the plant from which chocolate is produced—a discovery that could pave the way for climate-proof chocolate. The team’s research has been published in the journal Kew Bulletin.
The new species, discovered in the rain forests of South America, are closely related to Theobroma cacao, the tree that bears cocoa beans which are of tremendous economic importance.
The research team comprising scientists from University College Cork (UCC), the University of São Paulo and New York Botanical Garden say their finding is significant as it indicates that there is much work still to be done in characterizing Earth’s biodiversity.
Year 2023 Basically solar will last several billion years and make type 0 civilization resources obsolete by making trillions of dollars in profits with nearly zero emissions.
Between the Covid-19 pandemic, the Ukraine conflict, inflation, and the renewables transition, the 2020s have been a volatile decade for energy. The pandemic reduced demand for electricity and oil all over the world, causing prices to plummet. Then the Ukraine invasion brought sanctions on Russian oil and gas, pushing energy prices up and leaving European countries scrambling (particularly for natural gas). High energy prices have since contributed to inflation, and in many places utility costs are far surpassing inflation. All the while, worry over climate change has continued to mount, with calls to reduce our dependence on fossil fuels growing ever louder.
In short, the energy situation in the US and around the world is a mess. But the International Energy Agency released some good news in its recent World Energy Investment report. The report is compiled annually, and the 2023 version came out at the end of May. For the first time ever, it found that investment in renewables—specifically solar power—will overtake spending on oil.

Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study published this month. The work is published in the Journal of Advances in Modeling Earth Systems.
The research team, led by scientists from the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), used an innovative model that allows for higher-resolution simulations of hurricane formation than ever before. This allowed researchers to study the effects of increased regional moisture over Africa, which is the birthplace of weather systems that later produce hurricanes over the Atlantic.
Past research has suggested that warmer ocean water and a moister atmosphere could cause hurricanes to become more intense with greater amounts of rainfall. But how atmospheric moisture, which is predicted to increase in a warming climate, may be impacting hurricane formation itself has not been studied in detail until now.
Exposure to extreme temperatures during early life is associated with alterations in children’s brain white matter microstructure, particularly in lower socioeconomic status neighborhoods, highlighting potential vulnerability to climate change impacts.
Could we identify an alien terraformed planet through the detection of greenhouse gases? This is what a recent study published in The Astrophysical Journal hopes to address as a team of international researchers investigated whether artificial greenhouse gases could be detected from an exoplanet whose alien inhabitants could be attempting to terraform that world, either from trying to control its climate or terraforming an uninhabitable planet into a habitable one. This study holds the potential to help scientists better understand the criteria and methods for identifying an extraterrestrial civilization, especially with the number of confirmed exoplanets increasing almost weekly.
“For us, these gases are bad because we don’t want to increase warming” said Dr. Edward Schwieterman, who is an Assistant Professor of Astrobiology at the University of California Riverside and lead author of the study. “But they’d be good for a civilization that perhaps wanted to forestall an impending ice age or terraform an otherwise-uninhabitable planet in their system, as humans have proposed for Mars.”
MIT researchers have used simulations to suggest that the shorelines of Titan, Saturn ’s largest moon, are shaped by waves. This finding builds on images from NASA ’s Cassini spacecraft, which first confirmed the existence of Titan’s methane and ethane bodies. Understanding how these waves might erode the coastlines could offer insights into Titan’s climate and future sea evolution.
Titan’s Unique Extraterrestrial “Waters”
Titan, Saturn’s largest moon, is the only other planetary body in the solar system that currently hosts active rivers, lakes, and seas. These otherworldly river systems are thought to be filled with liquid methane and ethane that flows into wide lakes and seas, some as large as the Great Lakes on Earth.
A recent study has uncovered that a major earthquake around 2,500 years ago significantly rerouted the Ganges River in Bangladesh, marking the first documented instance of seismic activity causing a river avulsion. This discovery highlights the ongoing geological risks in delta regions, which could impact millions of people if repeated today. Credit: SciTechDaily.com.
A recent study published in Nature Communications reveals that a massive earthquake 2,500 years ago dramatically shifted the course of one of the world’s largest rivers. This previously undocumented seismic event rerouted the main channel of the Ganges River into present-day, densely populated Bangladesh, an area that continues to be at high risk for significant earthquakes.
Scientists have documented many river-course changes, called avulsions, including some in response to earthquakes. However, “I don’t think we have ever seen such a big one anywhere,” said study coauthor Michael Steckler, a geophysicist at Lamont-Doherty Earth Observatory, which is part of the Columbia Climate School. It could have easily inundated anyone and anything in the wrong place at the wrong time, he said.
Physics meets machine learning.
The Progress and Promise for Science in Indonesia Regional Special Feature focuses on biodiversity and climate change, highlighting research based on the unique geology and biology of a nation comprising more than 17,600 islands, containing about 10 percent of the world’s remaining tropical forests, and home to over 300,000 species of wildlife.
