Extreme heat is one of the leading causes of weather-related deaths in the U.S. Exposure to extreme heat will be exacerbated due to global climate change. It is thus crucial to design a key performance indicator, heat vulnerability index (HVI), to represent overall heat risk which can help identify susceptible regions and sub-populations in cities ...

Understanding contributions of climate and management intensifications to crop yield trends is essential to better adapt to climate changes and gauge future food security. Here we quantified the synergistic contributions of climate and management intensifications to maize yield trends from 1961 to 2017 in Iowa (United States) using a process-based ...

Oceanic motions with spatial scales of 200 m–20 km, called submesoscales, are ubiquitous in the upper ocean and serve as a key intermediary between larger-scale balanced dynamics and unbalanced turbulence. Here, we introduce the fluid dynamics of submesoscales and contrast them with motions at larger and smaller scales. We summarize the various way...

Iceberg calving accounts for half of the mass discharge from the Greenland and Antarctic ice sheets, which has increased dramatically over the last two decades. Through their displacement and progressive melt, icebergs can impact both the regional and large-scale ocean circulation and marine ecosystems by affecting their stratification and nutrient...
California’s water supplies are facing unprecedented stresses, and the state’s water-management systems are struggling to meet both environmental and human needs (agricultural, municipal, industrial). Supplies are highly vulnerable to climate variability and extreme events, limiting options to respond to the combined stresses of a changing climate,...

Introduction Cassava production is essential for food security in sub-Saharan Africa and serves as a major calorie-intake source in Nigeria. Estimating the yield gap in Nigeria is essential to indicate the most important limiting factors for production, and identify the yield gap hotspot areas. Secondly, these assessments may help set agendas in po...

Large outdoor fires have become commonplace all over the world. The International Organization for Standardization (ISO) defines large outdoor fires as an urban fire, tsunami-generated fire, volcano-generated fire, wildland-urban interface (WUI) fire, wildland fire, or informal settlement fire, where the total burnout area is significant. Perhaps o...
Black carbon emitted by incomplete combustion of fossil fuels and biomasshas a net warming effect in the atmosphere and reduces the albedo whendeposited on ice and snow; accurate knowledge of past emissions is essentialto quantify and model associated global climate forcing. Although bottom-upinventories provide historical Black Carbon emission est...
This report presents results based on in-depth field work in eight case studies of rural areas identified as having high access to services or as good examples in their national and regional context: Lolland, Suðuroy, Kinnula, Avannaata, Múlaþing, Herøy, Vimmerby and Geta. The aim of the field work has been to investigate service provision and vali...
Shamba shape is a farm makeover show which reaches over 8 million viewers in Kenya, and is now scalling up its reach to a show in Zambia and we would like to propose its scale up also to Uganda. The show will bring in new elements, providing seasonal forecasting to farmers with agro-advisory, reporting on FEWS-net early warning and agro-meteorologi...
