A fifth higher: Tropical cyclones substantially raise the Social Cost of Carbon      (via sciencedaily.com)     Original source 

Extreme events like tropical cyclones have immediate impacts, but also long-term implications for societies. A new study now finds: Accounting for the long-term impacts of these storms raises the global Social Cost of Carbon by more than 20 percent, compared to the estimates currently used for policy evaluations. This increase is mainly driven by the projected rise of tropical-cyclone damages to the major economies of India, USA, China, Taiwan, and Japan under global warming.

How do temperature extremes influence the distribution of species?      (via sciencedaily.com)     Original source 

As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.

Curators and cavers: How a tip from a citizen scientist led to deep discoveries in Utah's caves      (via sciencedaily.com)     Original source 

Scientists and colleagues from Utah's caving community have published the first research from their collaborative fieldwork effort deep in Utah's caves. The journal's feature article reveals why caves make such compelling research archives; what was uncovered in Boomerang Cave in northern Utah; why skeletal remains provide new access to hard-to-get data from the recent past; and offers a new zoological baseline for mammalian changes in an alpine community.

Deep-sea mining and warming trigger stress in a midwater jellies      (via sciencedaily.com)     Original source 

The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

AI finds formula on how to predict monster waves      (via sciencedaily.com)     Original source 

Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.

Microbiome development: Bacteria lay the foundations for their descendants      (via sciencedaily.com)     Original source 

The microbiome (the symbiotic community of microbial organisms of a host) is of existential importance for the functioning of every plant and animal, including human beings. A research team has now used the example of the sea anemone Nematostella vectenis to investigate how the microbiome develops together with the host. The researchers describe that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.

Deep dive on sea level rise: New modelling gives better predictions on Antarctic ice sheet melt      (via sciencedaily.com)     Original source 

Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise.   The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water.   Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team turned to the past.

Scientists have solved the damselfly color mystery      (via sciencedaily.com)     Original source 

For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.

Like the phoenix, Australia's giant birds of prey rise again from limestone caves      (via sciencedaily.com)     Original source 

Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again.    Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.

Temperature variability reduces nesting success      (via sciencedaily.com)     Original source 

Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.

Forget social distancing: House finches become more social when sick      (via sciencedaily.com)     Original source 

Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
