Meet the world’s 1st outdoor sweating, breathing and walking manikin
In the coming decades, every region in the U.S. is expected to experience higher temperatures and more intense heat waves. Thousands of people around the country die from heat-related illnesses each year, and in Maricopa County alone in 2022 there were 425 heat-related fatalities, a 25% increase from the previous year. ASU researchers aim to better understand heat stress on the human body and what makes hot weather so deadly using ANDI the world’s 1st outdoor sweating, breathing and walking manikin.

Randy Cerveny, the keeper of the world’s records of weather for the World Meteorological Organization (WMO) and a President’s Professor in ASU’s School of Geographical Sciences and Urban Planning shares insights about trends of extreme heat, the consequences of record-breaking temperatures and what the future may look like if current trends aren’t stalled or reversed.
Air Force Weather-funded research aims to improve predictability of extreme weather
As extreme weather devastates communities worldwide, scientists are using modeling and simulation to understand how climate change impacts the frequency and intensity of these events. Although long-term climate projections and models are important, they are less helpful for short-term prediction of extreme weather that may rapidly displace thousands of people or require emergency aid.

Less Rain in Town, More Rain on the Farm: the Effects of Urbanization and Irrigation on Mid-Atlantic Summer Precipitation
Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region. They found that urbanization suppresses all three types of precipitation. Irrigation enhances non-convective and isolated deep convection precipitation, and its effects on mesoscale convective systems (MCS) depends on whether an MCS formed locally or remotely.

A Better Understanding of Gas Exchange Between the Atmosphere and Ocean Can Improve Global Climate Models
The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exchange in high latitudes is important for several reasons, including to better constrain climate models that are used to predict changes in the ocean inventory of key gases like oxygen and carbon dioxide.

Game Changers in Fighting Climate Change: Refuels Are Suitable for Everyday Use
Synthetic fuels produced from renewable sources, so-called refuels, are deemed potential game changers in fighting climate change. Refuels promise to reduce CO2 emissions by up to 90% compared to conventional fuels and they allow for the continued use of existing vehicle fleets with combustion engines and of the refueling infrastructure, from fuel production to transport to sales. Researchers of Karlsruhe Institute of Technology (KIT) carried out extensive fleet tests in a large-scale project with industry partners and proved that refuels can be used in all vehicles and produced in large quantities in the foreseeable future. The results of the research project “reFuels – Rethinking Fuels” were presented on Monday, September 19, in Karlsruhe.

Nitrogen Footprint: Heavy Pollution and Resource Losses Due to Liquid Manure
Factory farming for meat production is harmful to the environment. In addition to its direct emissions of methane, its use of liquid manure releases climate-damaging nitrogen compounds such as ammonia and nitrous oxide into the atmosphere and pollutes the groundwater with nitrates. Researchers at the Karlsruhe Institute of Technology (KIT) have analyzed how the liquid manure produced by livestock farming, which is often used as fertilizer, affects its nitrogen footprint. They showed that the nitrogen pollution caused by liquid manure from the production of beef is three times higher than that for pork and eight times higher than that for poultry
Researchers pulled 700,000 years of glacial history from an Andean lakebed
Our understanding of the ice-age cycles has been limited by a lack of well-dated tropical records to understand the past of climate change. However, a core of mud from Lake Junín discovered by a team of researchers provides the first continuous and independently dated archive of tropical glaciation that reveals more than 700,000 years of glacial records.
UCI study: California’s trees are dying, and might not be coming back
The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state’s climate-change solution arsenal may be in jeopardy, as new research from the University of California, Irvine reports that trees in California’s mountain ranges and open spaces are dying from wildfires and other pressures – and fewer new trees are filling the void.

The facility is to be built in the Black Forest or the Odenwald range, with the Helmholtz Association providing 35 million euros in funding.
Thin-film Photovoltaic Technology Combines Efficiency and Versatility
Stacking solar cells increases their efficiency. Working with partners in the EU-funded PERCISTAND project, researchers at the Karlsruhe Institute of Technology (KIT) have produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent – the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, portable equipment, and devices that can be folded or rolled up. The researchers present their results in the journal ACS Energy Letters (DOI: 10.1021/acsenergylett.2c00707)

Restoring native predator populations could help to keep in check some of the most problematic invasive species around the world, suggests a new study led by Queen’s University Belfast and Cornell University.
Clouds played an important role in the history of climate
Were Earth’s oceans completely covered by ice during the Cryogenian period, about 700 million years ago, or was there an ice-free belt of open water around the equator where sponges and other forms of life could survive? Using global climate models, a team of researchers from Karlsruhe Institute of Technology (KIT) and the University of Vienna has shown that a climate allowing a waterbelt is unlikely and thus cannot reliably explain the survival of life during the Cryogenian. The reason is the uncertain impact of clouds on the epoch’s climate. The team has presented the results of its study in the journal Nature Geoscience (DOI: 10.1038/s41561-022-00950-1).
