The researchers emphasize the importance of developing risk-mitigating strategies to address this issue and highlight the potential consequences of not doing so.
Recent consecutive years of record high temperatures and droughts are unprecedented in over 250 years, according to researchers. The combination of heatwaves and soil moisture loss accelerates more heatwaves, threatening the region's ecosystem.
A new study using tree-ring data found that inner East Asia experienced a unique and unprecedented rise in heatwave-drought events over the last two decades. The findings suggest a positive feedback loop between declining soil moisture and increasing surface warming, potentially leading to more frequent and severe events.
Researchers from the University of Copenhagen have analyzed satellite imagery to study vegetation trends in arid regions, finding a clear trend of declining vegetation growth in developing countries, while wealthier nations experience increased growth. This uneven impact may lead to food shortages and climate refugees.
Research reveals German media outlets use eight frames to undermine legitimate climate change protests, reducing protesters' self-agency and marginalizing their voice. Despite this, the idea of intergenerational justice and children's rights has become established on the agenda.
The GOSAT-2 satellite has revealed unprecedented global concentrations of CO2, CH4, and CO. The full physics method used for the retrieval results shows column-averaged dry-air mole fractions of these three gas species. The data show high CO concentrations in regions with fossil fuel use and forest fires.
A UCLA study published in Science found that desert tortoises with higher genetic variation had higher survival rates after relocation. The researchers analyzed blood samples from 79 surviving and 87 deceased tortoises and found that survivors averaged 23% greater heterozygosity than those that perished.
Researchers combine machine learning with cell engineering to create living medicines that selectively kill cancer cells while leaving normal tissue unscathed. By analyzing massive databases of proteins, they assemble a catalog of combinations that can precisely target tumors, overcoming the limitations of current treatments.
A new co-governance model aims to save species such as salmon and southern resident killer whales from extinction through a $381 million conservation plan. The study highlights the importance of urban biodiversity conservation and investment in strategies like habitat restoration and public land management.
Scientists have developed a new method for analyzing the structure of skin using T-rays, which can help diagnose and treat conditions like eczema and psoriasis. The technique measures the refractive index of skin to determine hydration levels, providing valuable information on skin thickness and properties.
Researchers have discovered that synthetic microswimmers can change direction and swim back towards the source of light after being exposed, mimicking biological organisms. The behavior is triggered by Brownian motion, which sets in when the particles are no longer illuminated.
