Effectiveness of GBGI infrastructure in mitigating urban heat, proposing nine-stage framework for development of a sustainable city      (via sciencedaily.com)     Original source 

Primarily due to the impact of urbanisation and global warming, urban heatwaves have become a challenging issue worldwide, with Hong Kong persistently experiencing record-breaking high-temperature days. Mitigating urban heat through green and blue infrastructures is essential for creating a sustainable environment. Researchers have conducted a study on the effectiveness of green interventions in cooling urban heat across various regions that can assist policymakers in prioritizing effective interventions to develop sustainable cities.

Sexual parasitism helped anglerfish invade the deep sea during a time of global warming      (via sciencedaily.com)     Original source 

Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.

Extreme temperatures may increase risk of stroke mortality, especially in low-income countries      (via sciencedaily.com)     Original source 

Extreme heat and extreme cold are both associated with increased risks of death from ischemic and hemorrhagic stroke, according to a new study. The researchers found that the link between extreme temperatures and stroke mortality was stronger in low-income countries than in high-income countries.

New insights into the degradation dynamics of organic material in the seafloor      (via sciencedaily.com)     Original source 

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

Alaska's rusting waters: Pristine rivers and streams turning orange      (via sciencedaily.com)     Original source 

Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.

Researchers discover hidden step in dinosaur feather evolution      (via sciencedaily.com)     Original source 

Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.

Warming climate intensifies flash droughts worldwide      (via sciencedaily.com)     Original source 

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.

'Vigorous melting' at Antarctica's Thwaites 'Doomsday' Glacier      (via sciencedaily.com)     Original source 

Glaciologists show evidence of warm ocean water intruding kilometers beneath grounded ice at Thwaites Glacier in West Antarctica. The findings suggest that existing climate models are underestimating the impact of ocean and ice interactions in future sea level rise projections.

U.S. drought-monitoring system outpaced by climate changes      (via sciencedaily.com)     Original source 

A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.
