How do oceanic anoxic events affect oxygen fugacity of convergent margin magmas?
Granitoids are classified into magnetite-series and ilmenite-series, and the former have higher oxygen fugacity than the latter. Magmatic oxygen fugacity is a key factor in controlling the mineralization type......»»
AI for Earth: How NASA"s artificial intelligence and open science efforts combat climate change
As extreme weather events increase around the world due to climate change, the need for further research into our warming planet has increased as well. For NASA, climate research involves not only conducting studies of these events, but also empoweri.....»»
Mars rover continues progress along upper Gediz Vallis ridge
Curiosity continues to make progress along the margin of upper Gediz Vallis ridge, investigating the broken bedrock in our workspace and acquiring images of the ridge deposit as the rover drives south......»»
Scientists trigger mini-earthquakes in the lab
Earthquakes and landslides are famously difficult to predict and prepare for. By studying a miniature version of the ground in the lab, scientists at the UvA Institute of Physics have demonstrated how these events can be triggered by a small external.....»»
Unraveling the mysteries of consecutive atmospheric river events
In California's 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages—the longest duration of continuous AR conditions in the past 70 years. Scientists at Lawrence Berkele.....»»
Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future
The 2010 Gulf of Mexico Deepwater Horizon was the largest accidental oil spill in history. With almost 100 million gallons (379 million liters) of oil combined with dispersants suggested to remain in the Gulf, it is one of the worst pollution events.....»»
Team finds direct evidence of "itinerant breeding" in East Coast shorebird species
Migration and reproduction are two of the most demanding events in a bird's annual cycle, so much so that the vast majority of migratory birds separate the two tasks into different times of the year......»»
Weather and climate extremes in 2023 impacting the globe with emerging features
Globally, last year was the warmest for thousands of years, with a globally averaged temperature of at least 1.45°C greater than pre-industrial times. The year also saw an unprecedented string of extreme weather and climate events in many parts of t.....»»
Climate damages by 2050 will be 6 times the cost of limiting warming to 2°
Study tracks the past costs of climate events and projects them into the future. Enlarge (credit: Frame Studio) Almost from the start, arguments about mitigating climate change have included an element of cost-benefit an.....»»
A chunk of metal that tore through a Florida home definitely came from the ISS
"I don't think I've seen or heard, after my own research, any of these events occurring." NASA has confirmed that the object that fell into a Florida home last month was part of a battery pack released from the International Space St.....»»
Scientists navigate the paradox of extreme cold events in a warming world
According to Copernicus Climate Change Service, February 2024 was the warmest February ever recorded globally......»»
Study reveals substantial global cost of climate inaction
Traditionally, estimates of how climate change will affect global economies have focused on the effects of annual temperature changes. However, the additional impacts of variability and extremes in rainfall and temperature have remained largely unexp.....»»
How a cyanobacterium manages iron scarcity makes it the most successful photosynthetic organism on Earth
The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes appr.....»»
Tesla"s global job cuts include leading markets U.S., China
Tesla cuts jobs in U.S. and China amid falling sales. The layoffs affect sales and service positions. .....»»
Spectator boats at large sailing events could be impacting marine wildlife with noise pollution
New research led by Heriot-Watt University in Edinburgh, Scotland, suggests that international sailing events should try to reduce the underwater noise they create to avoid impacting marine wildlife......»»
Researchers reveal oceanic black carbon sink effect driven by seawater microdroplets
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic bla.....»»
Research suggests that part of India will become a climate hotspot
The Indian subcontinent is likely to experience an increasing number of extreme weather events in future. The fertile and densely populated plain around the Indus and Ganges rivers is therefore likely to become a climate change hotspot, which could h.....»»

First-of-its-kind study shows Florida Wildlife Corridor eases worst impacts of climate change
From rising temperatures and altered precipitation patterns to intense weather events such as hurricanes, Florida is experiencing significant climate-related challenges in tandem with skyrocketing insurance rates. As the state's population continues.....»»
Unraveling differences in temperature sensitivity of soil organic matter decomposition under various oxygen conditions
Soil organic matter (SOM) decomposition is a key process that affects soil carbon storage and greenhouse gas emissions. Investigating the temperature sensitivity (Q10) of SOM decomposition and its regulating mechanisms is important for improving pred.....»»
Reptiles in South Africa are under threat, but there"s good news too
Media reports about the biodiversity crisis and what researchers have argued qualifies as a mass extinction event tend to focus on the big ecological effects. Melting ice sheets, severe weather events, droughts, habitat loss and wildfires dominate he.....»»
