Can East Asian monsoon enhancement induce global cooling?

9 hours 10 minutes ago
The study of the orogenic effects of the Tibetan Plateau uplift on global climate during the Cenozoic has focused almost exclusively on the India-Asia collision zone, the Himalayas. The strong erosion in the Himalayas was assumed to be a primary driver of Cenozoic atmospheric CO2 decline and global cooling predominantly through accelerating silicate chemical weathering in the India-Asia collision zone or through effective burial of organic carbon in the nearby Bengal Fan in South Asia. 

Volcanic tremor and deformation at Kīlauea

11 hours 22 minutes ago
Kīlauea in Hawaii is the best-monitored volcano in the world. The 2018 eruption was the largest in some 200 years, providing researchers with a plethora of new data to understand the volcano's plumbing and behavior. Two new studies dig into data on volcanic tremor and deformation to better characterize the events leading up to and following the 2018 eruption.

How the pandemic has impacted environmental field research

Field stations and marine laboratories (FSMLs) serve as great drivers of research, monitoring, and learning about our world. However, FSMLs across the globe are facing major cutbacks and even closure due to COVID-19 pandemic-driven budget cuts. UConn's Gene E. Likens and David L. Wagner, professors in the Department of Ecology and Evolutionary Biology, have written an editorial in Science outlining the importance of these vital "sentinels" while calling attention to the dangers we face if these global observatories are to be closed. They met with UConn Today to explain the issues. The conversation has been edited and condensed for clarity.

Particles from paints, pesticides can have deadly impact

12 hours 21 minutes ago
Hundreds of thousands of people around the world die too soon every year because of exposure to air pollution caused by our daily use of chemical products and fuels, including paints, pesticides, charcoal and gases from vehicle tailpipes, according to a new CU Boulder-led study.

Image: Smoke billows from fires in Turkey

12 hours 31 minutes ago
Captured by the Copernicus Sentinel-3 mission on 30 July 2021, this image shows smoke billowing from several fires along the southern coast of Turkey. Turkey has been battling deadly wildfires since last week. Over the weekend, tourists and local residents had to be evacuated from Bodrum and Marmaris, with some fleeing by boat as the flames crept closer to the shoreline. Southeast Europe is currently experiencing extremely high temperatures. Greece is reported to be expecting an all-time European record today of 47°C. The heatwave, the result of a heat dome, has seen temperatures reach above 40°C in many areas, and meteorologists expect the weather will continue this week, making it the most severe heatwave since the 1980s.

Trapped saltwater caused mangrove death after Hurricane Irma

1 day 4 hours ago
When Hurricane Irma hit southern Florida in September of 2017, the storm buffeted coastal mangrove forests with winds over 116 mph—strong enough to rip off leaves, break branches, and snap tree trunks in half. Of the mangrove forest damaged by Hurricane Irma, about 83% recovered after the first year. But the rest didn't, leaving scientists wondering why some trees didn't bounce back.

New model tracks carbon in agroecosystems

1 day 5 hours ago
Carbon is everywhere. It's in the atmosphere, in the oceans, in the soil, in our food, in our bodies. As the backbone of all organic molecules that make up life, carbon is a very accurate predictor of crop yields. And soil is the largest carbon pool on earth, playing an important role in keeping our climate stable.

Thawing permafrost releases greenhouse gas from depth

1 day 6 hours ago
Which effects did the heat wave of summer 2020 have in Siberia? In a study led by the University of Bonn (Germany), geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last year's heat wave indicate that increased gas emissions came from limestone formations. The study is published in the journal Proceedings of the National Academy of Sciences (PNAS).
