    Scientists have created the first global map showing how ocean tides influence rivers far inland, revealing a major but overlooked flood risk affecting millions worldwide. The research, led by Technical University of Munich, shows that tides do not stop at coastlines. Instead, they travel upstream through rivers, increasing flood risks in inland areas. The study found that over 725 million people live in regions affected by tidal river influence, with more than 175,000 kilometres of rivers impacted globally. In some cases, tidal effects extend hundreds of kilometres inland, such as in the Amazon River. This new mapping tool helps identify vulnerable regions and track how risks may shift with climate change and rising sea levels. Researchers say the data will be...

    A new scientific study is challenging the way the world measures global warming, warning that current methods may be undervaluing some of the most effective ways to slow climate change particularly efforts to cut methane emissions. Published in the journal Environmental Research Letters, the research proposes a new framework called Radiative Forcing-based Accounting (RFA), which aims to more accurately capture how different greenhouse gases affect the Earth’s temperature over time. The study has significant implications for climate policy, carbon markets, and the valuation of emissions reduction projects. For decades, global climate policy has relied on a standard unit known as carbon dioxide equivalent (CO2e) to compare the impact of different greenhouse gases. T...

    In the drought-stricken fields of northern Iraq, farmers are rethinking centuries-old agricultural practices as climate change disrupts rainfall patterns and threatens rural livelihoods. A new initiative supported by the International Organization for Migration (IOM) is helping communities adapt through climate-smart farming techniques, offering a lifeline to families facing growing uncertainty. In Ewaynat village in Ninewa province, farming once followed a predictable rhythm shaped by seasonal rains. Today, that rhythm has been broken. Years of drought, rising temperatures, and erratic rainfall have made harvests unreliable and farming increasingly risky. “The land had a rhythm, but now that rhythm feels broken,” said Mohammed, a local farmer who has witnessed th...

    Rapid glacier melt in Bolivia is giving rise to dozens of new high-altitude lakes, increasing the risk of sudden and potentially devastating floods for mountain communities, according to new research published by The Conversation. Scientists warn that as glaciers retreat at an accelerating pace, these newly formed lakes could trigger dangerous events known as glacial lake outburst floods (GLOFs) sudden releases of water caused by the collapse of natural barriers such as ice or rock. Such events have already proven deadly elsewhere, including a 2023 disaster in India’s Teesta Valley that claimed dozens of lives. The study found that between 2016 and 2022, glaciers in the Bolivian Andes shrank by nearly 10 percent, losing surface area at an average rate of almost tw...

    A groundbreaking design inspired by nature is reimagining how degraded landscapes can be restored, turning one of the most iconic symbols of desolation into a tool for ecological recovery. Created by designer Yizhuo Guo, the “Wasteland Nomads: Bionic Tumbleweed Sower System” uses wind energy and biodegradable materials to regenerate barren land without leaving any environmental footprint. Developed in collaboration with Daheng Chu and supported by institutions including University of the Arts London and Imperial College London, the project draws inspiration from the natural movement of tumbleweeds. These plants, often associated with dry and abandoned landscapes, disperse seeds as they roll across terrain. Guo’s innovation builds on this principle, transforming it in...

    The world marked International Day of Forests on March 21 with a renewed focus on the economic value of forest ecosystems, as the 2026 theme “Forests and Economies” placed forests at the centre of global development and sustainability discussions. First established by the United Nations General Assembly in 2012, the annual observance aims to raise awareness about the importance of all types of forests and encourage conservation efforts through activities such as tree plantation drives and policy initiatives at local, national and international levels. This year’s theme underscores how forests are not only ecological assets but also powerful economic engines. From supporting livelihoods to driving sustainable industries, forests contribute significantly to global a...

    A groundbreaking study led by researchers from Technical University of Munich has produced the world’s first global map showing how tidal movements from oceans travel inland through rivers, exposing millions to previously underestimated flood risks. The research highlights that tides do not stop at coastlines. Instead, their influence moves upstream through coastal rivers, creating what scientists call a “tidal pulse.” These periodic fluctuations can significantly increase flood risks in inland regions, especially as climate change drives rising sea levels and extreme weather events. According to the study, more than 725 million people worldwide are directly affected by these tidal influences. The findings reveal that over 175,000 kilometres of rivers across the g...

    A surprising discovery has revealed that several lakes on K’gari disappeared for nearly 2,000 years despite a wetter climate, challenging long-held scientific beliefs. Researchers found that lakes like Boorangoora and Allom dried out between 7,500 and 5,500 years ago. This finding contradicts earlier assumptions that the lakes remained full since the last ice age. The evidence comes from sediment records, which act like natural timelines. A complete absence of deposits during this period indicates that the lakes were dry for centuries. Scientists believe shifting wind patterns may have redirected rainfall away from the island, showing how local climate systems can behave unpredictably even during wetter periods. The findings raise concerns about the future s...

    Africa’s coastlines are entering a dangerous new phase as sea levels rise faster than previously recorded, according to research led by the University of Cape Town. The study found that the 2023–2024 El Niño triggered the largest sea level surge ever observed in the region, surpassing even the historic 1997–1998 event. Since 1993, sea levels around Africa have risen by over 11 cm, accelerating at an increasing rate. Researchers say this surge was not caused by El Niño alone. A rare combination of climate patterns, including warming oceans and atmospheric changes, amplified the impact. Over 70% of the rise was driven by thermal expansion, where warming water expands and raises sea levels. The consequences are severe. More than 15 million people in coastal cities...

    A silent crisis is unfolding beneath the Earth’s surface, where groundwater reserves are rapidly declining without visible warning. According to the United Nations University, this hidden depletion is putting drinking water, agriculture and global food systems at serious risk. Unlike shrinking rivers or reservoirs, groundwater loss often goes unnoticed. Scientists warn that aquifers, which act like natural water banks, are being overdrawn as extraction exceeds natural recharge. This imbalance has led experts to describe the situation as “water bankruptcy,” where water is consumed faster than it can be replenished. Regions such as India, northeastern China and the western United States are already facing severe depletion. As groundwater levels fall, wells may event...
