New reptile on the block: A new iguana species discovered in China      (via sciencedaily.com)     Original source 

Researchers have identified a new iguana species, Wang's garden lizard (Calotes wangi), in southern China and northern Vietnam. This species, part of the Calotes versicolor complex, was discovered through extensive surveys conducted from 2009 to 2022. Measuring less than 9 cm with an orange tongue, it inhabits subtropical and tropical forests, thriving in various landscapes including urban areas.

Same and different: A new species of pit viper from Myanmar      (via sciencedaily.com)     Original source 

Asian pit vipers of the genus Trimeresurus are notoriously difficult to tell apart and continue puzzling researchers to this day. Some species groups have similar-looking species (different species that look alike), while others exhibit extreme variation within a single species (same species that look different). Scientists have now discovered a new species of pit viper from Myanmar that is both similar and different from its adjacent sister species.

Low economic growth can help keep climate change within the 1.5 °C threshold      (via sciencedaily.com)     Original source 

A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5 °C, as per the Paris Agreement. A recent study shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.

Exoplanets' climate -- it takes nothing to switch from habitable to hell      (via sciencedaily.com)     Original source 

The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two bears to only a few degrees in temperature. A team of astronomers has achieved a world's first by managing to simulate the entirety of the runaway greenhouse process which can transform the climate of a planet from idyllic and perfect for life, to a place more than harsh and hostile. The scientists have also demonstrated that from initial stages of the process, the atmospheric structure and cloud coverage undergo significant changes, leading to an almost-unstoppable and very complicated to reverse runaway greenhouse effect. On Earth, a global average temperature rise of just a few tens of degrees, subsequent to a slight rise of the Sun's luminosity, would be sufficient to initiate this phenomenon and to make our planet inhabitable.

Seals stay warm and hydrated in the Arctic with larger, more convoluted nasal passages      (via sciencedaily.com)     Original source 

Arctic seals have evolved many adaptations to cope with their frosty environment -- one that you might not immediately think of is the bones in their nasal cavity. Arctic seals have more convoluted nasal passages than seal species that live in milder environments, and researchers report that these structures help the seals more efficiently retain heat and moisture as they breathe in and out.

How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.

The solar forest      (via sciencedaily.com)     Original source 

What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.
