The ocean is our greatest climate regulator. It must be a stronger part of climate policy and action

Increasing ocean science in developing countries is a future focus. Author provided, CC BY-ND The German linguist Heinrich Zimmer once described the ocean as “limitless and immortal … the beginning and end of all things on Earth”. Standing on the shores of any ocean, one can easily sense this. Yet, the more we reveal about the myriad processes within the world’s oceans, the more we begin to question just how limitless and immortal the ocean truly is. The ocean is … Continue reading “The ocean is our greatest climate regulator. It must be a stronger part of climate policy and action”

Radar remote sensing reveals magnitudes and patterns of large-scale permafrost ground deformation

Seasonal and linear ground deformation on the central Qinghai-Tibet Plateau. Credit: Chen Jie Permafrost on the Qinghai-Tibet Plateau (QTP) undergoes significant thawing and degradation under climate warming. Ground deformation is a key indicator of permafrost degradation, which can be quantified via the advanced multi-temporal Interferometric Synthetic Aperture Radar (InSAR) techniques. However, due to the strong heterogeneity of freeze-thaw processes, the magnitudes and patterns of large-scale ground deformation on QTP is not fully understood. Researchers from the Northwest Institute of Eco-Environment … Continue reading “Radar remote sensing reveals magnitudes and patterns of large-scale permafrost ground deformation”

Iceland’s journey to the centre of the Earth

In northeast Iceland, researchers plan to drill into the heart of the Krafla volcano to create an underground magma observatory. With its large crater lake of turquoise water, plumes of smoke and sulphurous bubbling of mud and gases, the Krafla volcano is one of Iceland’s most awe-inspiring natural wonders. Here, in the country’s northeast, a team of international researchers is preparing to drill two kilometres (1.2 miles) into the heart of the volcano, a Jules Verne-like project aimed at creating … Continue reading “Iceland’s journey to the centre of the Earth”

Study links increasing air pollution to the rise of a type of lung cancer

Credit: Unsplash/CC0 Public Domain An international team of scientists, led by Nanyang Technological University, Singapore (NTU Singapore), has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. The same study also concluded an overall lower consumption of tobacco worldwide is statistically linked to less people contracting lung squamous cell carcinoma (LSCC). Lung adenocarcinoma is a type of cancer for which research strongly suggests that genetic, environmental, and lifestyle factors play a part, while lung squamous … Continue reading “Study links increasing air pollution to the rise of a type of lung cancer”

Researchers reconstruct historical non-growing-season precipitation in southeastern Tibetan Plateau

Natural-colour satellite image of the Tibetan Plateau. Credit: NASA A joint research team led by researchers from the Xinjiang Institute of Ecology and Geography (XIEG) and the Research Center for Eco-Environmental Sciences (RCEES) of the Chinese Academy of Sciences has reconstructed the historical non-growing-season (from November of the previous year to February of the current year) precipitation in the southeastern Tibetan Plateau using tree rings. The study was published in Climate of the Past. The Tibetan Plateau plays a key … Continue reading “Researchers reconstruct historical non-growing-season precipitation in southeastern Tibetan Plateau”

Trees found to reduce land surface area temperatures in cities up to 12°C

Credit: Unsplash/CC0 Public Domain A team of researchers with the Institute for Atmospheric and Climate Science, ETH Zurich, has found evidence that indicates that stands of trees can reduce land surface area temperatures in cities up to 12°C. In their paper published in the journal Nature Communications, the group describes how they analyzed satellite imagery for hundreds of cities across Europe and what they learned. Prior research has suggested that adding green spaces to cities can help reduce high air … Continue reading “Trees found to reduce land surface area temperatures in cities up to 12°C”

How warm weather or bright lights can influence tree greening

Credit: Lin Meng Lin Meng has been named the grand prize winner of this year’s Science & SciLifeLab Prize for Young Scientists for research she conducted on how both global warming and bright city lights can impact phenology in trees (when they begin to grow leaves in the spring). In her paper published in the journal Science, Meng outlines her study of satellite data showing green areas in cities along with artificial light sources and also trees growing in the … Continue reading “How warm weather or bright lights can influence tree greening”

China’s carbon emissions fall for first time since COVID lockdowns: report

China’s CO2 emissions fell in the third quarter for the first time since the country reopened from Covid-19 lockdowns. China’s CO2 emissions fell in the third quarter for the first time since the country reopened from COVID-19 lockdowns, research published Thursday showed, in what experts said could mark a carbon “turning point” for the country. But the threat of economic slowdown could soon prompt authorities to turn to infrastructure stimulus measures, raising emissions again, the research by the Centre for … Continue reading “China’s carbon emissions fall for first time since COVID lockdowns: report”

New breakthrough in surface-based groundwater measurement

Credit: CC0 Public Domain Based on recent breakthroughs in instruments and data modeling, researchers from the Department of Geoscience and the Department of Electrical and Computer Engineering at Aarhus University have collaborated to develop an effective technology to measure groundwater accurately from the surface. The new technology sends very much cleaner signals than have so far been possible using NMR-based (nuclear magnetic resonance) measurements, and this enables the researchers to make a detailed map of the hydrogeological and geological structure … Continue reading “New breakthrough in surface-based groundwater measurement”
