Researchers have found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations found that just 2.2% of tree species make up 50% of the total number of trees in tropical forests across Africa, the Amazon, and Southeast Asia. Each continent consists of the same proportion of a few common species and many rare species.

Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss.

A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.

Analysis of iron meteorites from the earliest years of the solar system indicate that the planetary 'seeds' that ultimately formed Earth contained water.

Felspar dust in the air can create clouds. The feldspar particles act as nucleation sites to which water molecules can attach extremely efficiently. Why this is the case has remained a mystery for a long time. Scientists have now studied feldspar using a special atoimic force microscope and managed to explain this remarkable property of feldspar on an atomic level. The atomic structure is just right to create a layer of OH-groups which in turn can connect to water molecules perfectly.

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Researchers have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been confined within the lithosphere for an extensive period of 1.5-5 million years. They identified three primary sources for this ancient water: the Philippine Sea Plate, the Pacific Plate, and ancient seafloor sediments, particularly in the Niigata and southwest Gunma regions.

A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.

New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.

The largest analysis yet of African savannah elephant populations shows that conservationists have successfully protected elephants in southern Africa for the last 25 years. However, the pattern varies regionally, with some elephant populations soaring and others still facing large declines. The key to long-term stability appears to be connecting large core areas with neighboring buffer zones, as opposed to well-protected but isolated protected areas known as 'fortress conservation.'

Researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.

A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.

In Hawaii and across much of Oceania, Pacific Islanders celebrate the connections between their islands and the ocean that surrounds them.

Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.

A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.

Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.

How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
