A new perspective on the temperature inside tropical forests      (via sciencedaily.com)     Original source 

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.

Complex green organisms emerged a billion years ago      (via sciencedaily.com)     Original source 

Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.

Planetary Commons: Fostering global cooperation to safeguard critical Earth system functions      (via sciencedaily.com)     Original source 

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.

Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows      (via sciencedaily.com)     Original source 

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.

Ice age could help predict oceans' response to global warming      (via sciencedaily.com)     Original source 

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.

A window into plant evolution: The unusual genetic journey of lycophytes      (via sciencedaily.com)     Original source 

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.

How does one species become many?      (via sciencedaily.com)     Original source 

A global team of biologists has compiled nearly two decades of field data -- representing the study of more than 3,400 Darwin's finches in the Galapagos Islands -- to identify the relationship between beak traits and the longevity of individual finches from four different species.

Sea otters helped prevent widespread California kelp forest declines over the past century      (via sciencedaily.com)     Original source 

The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.

Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird      (via sciencedaily.com)     Original source 

The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.

Next-generation batteries could go organic, cobalt-free for long-lasting power      (via sciencedaily.com)     Original source 

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.

The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance      (via sciencedaily.com)     Original source 

Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.

Climate change isn't producing expected increase in atmospheric moisture over dry regions      (via sciencedaily.com)     Original source 

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.

Stalagmites as climate archive      (via sciencedaily.com)     Original source 

When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations, a research team has demonstrated. The researchers analyzed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany. In conjunction with the data acquired from tree rings, they were able to reconstruct short-term climate fluctuations over centuries and correlate them with historically documented environmental events.

Chasing the light: Study finds new clues about warming in the Arctic      (via sciencedaily.com)     Original source 

The Arctic, Earth's icy crown, is experiencing a climate crisis like no other. It's heating up at a furious pace -- four times faster than the rest of our planet. Researchers are pulling back the curtain on the reduction of sunlight reflectivity, or albedo, which is supercharging the Arctic's warming.
