Australia's Great Barrier Reef sees record coral loss – DW – 08/06/2025
The Great Barrier Reef suffered its largest annual decline in live coral over the past year, according to a report released Wednesday by the Australian Institute of Marine Science.
Australian scientists monitoring the reef documented the devastating effects of a mass coral bleaching event that occurred in early 2024.
"The [Great Barrier Reef] experienced unprecedented levels of heat stress, which caused the most spatially extensive and severe bleaching recorded to date," the report found.
Surveys of the world's largest reef found that two of its three regions recorded the steepest coral decline since monitoring began in 1986.
According to the report, the northern and southern regions of the Great Barrier Reef were hit hardest, with coral cover dropping by between one-quarter and one-third after several years of steady growth.
Scientists documented the most widespread bleaching event since monitoring began nearly 40 years ago, driven by record-high ocean temperatures in 2024 that triggered "unprecedented levels of heat stress."
"We are now seeing increased volatility in the levels of hard coral cover," said Mike Emslie, head of the institute's long-term monitoring program.
"This is a phenomenon that emerged over the last 15 years and points to an ecosystem under stress," he added.
Emslie said the primary cause of the decline in coral cover is climate change.
"We have seen coral cover oscillate between record lows and record highs in a relatively short amount of time, where previously such fluctuations were moderate," he added.
The reef stretches for about 1,500 miles (2,400 kilometers) off the coast of Queensland in northeastern Australia.

Despite the damage, Emslie said the reef remains an "amazing place."
"It is still worth fighting for. We can't throw our arms up and give up," he said.

US scientists discover trees host up to 1 trillion microbes – DW – 08/06/2025
Healthy trees contain more than one trillion different bacteria, fungi and viruses, a new study has found. These wood microbiomes could hold clues about forest health and climate change. A new study has discovered that trees contain a rich and diverse microbiome inside their tree trunks, much like humans do in our bodies. An average tree contains approximately one trillion microbe cells, according to data acquired from sampling the DNA of 150 trees and published today in the journal . It found that healthy trees contain distinct microbiomes specialized to different parts of the tree and rich in fungi, bacteria, and viruses. The authors believe these could play a vital role in tree health. "Our study shows that each tree species hosts its own distinct microbial community that has evolved alongside the tree," said study co-author Jon Gewirtzman at Yale University, US. Katie Field, a plant biologist at Sheffield University, UK, who was not involved in the research, said the study "helps reredefine how we see trees — not just as standalone organisms, but as complex, integrated ecosystems that include a vast network of microbial life." "In the same way that human microbiomes are important for our health, this work suggests we may need to start thinking similarly about trees. It opens a whole new frontier for environmental microbiology, forest science, and even biotechnology," Field told DW. Microbes are an important part of plant life. The discovery of a 'wood-wide web' — a network that connects fungal filaments and tree roots in underground soil — led to the idea that other organisms aid plant growth and defence against pathogens. But little is known about the microbes living inside healthy wood. "The three trillion trees on Earth represent the world's largest pool of biomass, much of which hosts unique ecosystems we've never studied," said Gewirtzman. The researchers set out to study the microbiomes of trees in the Yale-Myers Forest in Connecticut, US. They took multiple samples from 150 trees across 16 species, including oaks, maples, and pines. Soil samples were also taken. They then extracted DNA from the wood and soil and analysed the data for evidence of DNA from bacteria, fungi, and viruses. They found that trees contain huge numbers of different microbe species — roughly one microbe for every 20 plant cells. This translates to between 100 billion and one trillion microbial cells on average, which is still far fewer than the 39 trillion inside humans. "This study provides some of the clearest evidence to date that the wood of living trees hosts distinct and adapted microbiomes, different to those of the surrounding soil, leaves, or tree roots," said Field.

The inner heartwood and outer sapwood contained completely different microbial communities. Denser heartwood was dominated by microbes that don't need oxygen, while the sapwood contained more oxygen-requiring microbes. Different microbiomes were also found in different tree species. Maple trees, for example, contained high abundance of microbes that are adept at breaking down sugars. Further experiments showed that different communities changed gas concentrations inside these woods.

More studies are needed to understand how microbiomes affect wider forest health, but the authors believe there is a link. "We know that certain microbes promote growth in certain model plants, including in major cereal crops and poplar trees, but there are thousands [of microbes] that we do not know the function of," Gewirtzman told DW via email. The study may also open new questions. For Field, this includes investigating the roles microbiomes play in tree aging, defence and decay. "There is also clear potential to explore whether managing or modifying wood microbiomes could help improve forest resilience or carbon cycling," said Field. Gewirtzman suggests it could also answer big picture questions about how climate change impacts trees, or whether tree microbiomes could be deployed for other purposes. "How will climate change affect these internal ecosystems and forest health? And can we harness these microbes for new forest management or biotechnology applications?" But Michael Köhler, a botanist at Martin Luther University Halle-Wittenberg, Germany, told DW it's far too early for Gewirtzman's group to start monitoring tree microbiomes to measure climate impacts and forest health. "We're investigating this at the moment — how climate change is affecting the microbiome of seeds and seedlings in grasslands," he told DW.

Australia's Great Barrier Reef sees record coral loss – DW – 08/06/2025
The reef still retains more coral cover than many reef systems globally and researchers say it is 'still worth fighting for.' The Great Barrier Reef suffered its largest annual decline in live coral over the past year, according to a report released Wednesday by the Australian Institute of Marine Science. Australian scientists monitoring the reef documented the devastating effects of a mass coral bleaching event that occurred in early 2024.

Landslide-prone Nepal Tests AI-powered Warning System
Every morning, Nepali primary school teacher Bina Tamang steps outside her home and checks the rain gauge, part of an early warning system in one of the world's most landslide-prone regions. Tamang contributes to an AI-powered early warning system that uses rainfall and ground movement data, local observations and satellite imagery to predict landslides up to weeks in advance, according to its developers at the University of Melbourne. From her home in Kimtang village in the hills of northwest Nepal, 29-year-old Tamang sends photos of the water level to experts in the capital Kathmandu, a five-hour drive to the south. "Our village is located in difficult terrain, and landslides are frequent here, like many villages in Nepal," Tamang told AFP. Every year during the monsoon season, floods and landslides wreak havoc across South Asia, killing hundreds of people. Nepal is especially vulnerable due to unstable geology, shifting rainfall patterns and poorly planned development. As a mountainous country, it is already "highly prone" to landslides, said Rajendra Sharma, an early warning expert at the National Disaster Risk Reduction and Management Authority. "And climate change is fuelling them further. Shifting rainfall patterns, rain instead of snowfall in high altitudes and even increase in wildfires are triggering soil erosion," Sharma told AFP. Landslides killed more than 300 people last year and were responsible for 70 percent of monsoon-linked deaths, government data shows. Tamang knows the risks first hand. When she was just five years old, her family and dozens of others relocated after soil erosion threatened their village homes. They moved about a kilometre (0.6 miles) uphill, but a strong 2015 earthquake left the area even more unstable, prompting many families to flee again. "The villagers here have lived in fear," Tamang said. "But I am hopeful that this new early warning system will help save lives." The landslide forecasting platform was developed by Australian professor Antoinette Tordesillas with partners in Nepal, Britain and Italy. Its name, SAFE-RISCCS, is an acronym of a complex title -- Spatiotemporal Analytics, Forecasting and Estimation of Risks from Climate Change Systems. "This is a low-cost but high-impact solution, one that's both scientifically informed and locally owned," Tordesillas told AFP. Professor Basanta Adhikari from Nepal's Tribhuvan University, who is involved in the project, said that similar systems were already in use in several other countries, including the United States and China. "We are monitoring landslide-prone areas using the same principles that have been applied abroad, adapted to Nepal's terrain," he told AFP. "If the system performs well during this monsoon season, we can be confident that it will work in Nepal as well, despite the country's complex Himalayan terrain." In Nepal, it is being piloted in two high-risk areas: Kimtang in Nuwakot district and Jyotinagar in Dhading district. Tamang's data is handled by technical advisers like Sanjaya Devkota, who compares it against a threshold that might indicate a landslide. "We are still in a preliminary stage, but once we have a long dataset, the AI component will automatically generate a graphical view and alert us based on the rainfall forecast," Devkota said. "Then we report to the community, that's our plan." The experts have been collecting data for two months, but will need a data set spanning a year or two for proper forecasting, he added. Eventually, the system will deliver a continuously updated landslide risk map, helping decision makers and residents take preventive actions and make evacuation plans. The system "need not be difficult or resource-intensive, especially when it builds on the community's deep local knowledge and active involvement", Tordesillas said. Asia suffered more climate and weather-related hazards than any other region in 2023, according to UN data, with floods and storms the most deadly and costly. And while two-thirds of the region have early warning systems for disasters in place, many other vulnerable countries have little coverage. In the last decade, Nepal has made progress on flood preparedness, installing 200 sirens along major rivers and actively involving communities in warning efforts. The system has helped reduce flooding deaths, said Binod Parajuli, a flood expert with the government's hydrology department. "However, we have not been able to do the same for landslides because predicting them is much more complicated," he said. "Such technologies are absolutely necessary if Nepal wants to reduce its monsoon toll."
