Researchers have discovered a change in what scientists already knew about global warming dynamics. It had been widely accepted since the 1950s that global temperature rises were not consistent throughout the day and night, with greater nighttime warming being observed. However, the recent study reveals a shift in dynamics: with greater daytime warming taking place since the 1990s. This shift means that the temperature difference between day and night is widening, potentially affecting all life on Earth.

Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed- - a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. Instead, the findings rely solely on internal geological forces that occurred within oceanic plateaus that formed during the first few hundred million years of Earth's history.

A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.

Researchers have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland. The results of the new study contribute with important knowledge for climate models. The researchers are now investigating whether the same finding applies to other polar regions.

A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.

Scientists no longer have direct access to data from Russian Arctic research stations. Without this data, our view of climate changes in the region is increasingly biased, new research shows.

Cryptocurrency is usually 'mined' through the blockchain by asking a computer to perform a complicated mathematical problem in exchange for tokens of cryptocurrency. But now a team of chemists have repurposed this process, asking computers to instead generate the largest network ever created of chemical reactions which may have given rise to prebiotic molecules on early Earth.

Groundwater is rapidly declining across the globe, often at accelerating rates. Researchers now present the largest assessment of groundwater levels around the world, spanning nearly 1,700 aquifers. In addition to raising the alarm over declining water resources, the work offers instructive examples of where things are going well, and how groundwater depletion can be solved. The study is a boon for scientists, policy makers and resource managers working to understand global groundwater dynamics.

The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.

New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.

Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.

An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.

A new way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age could help explain the role oceans played in past glacial melting cycles and improve predictions of how ocean carbon cycles will respond to global warming.

Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.

In the switch to 'greener' energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt -- a metal whose extraction has high environmental and societal costs. Now, researchers in report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance.
