A Linear Sensitivity Framework to Understand the Drivers of the Wet‐Bulb Globe Temperature Changes

Journal of Geophysical Research Atmospheres, Journal Year: 2025, Volume and Issue: 130(5)

Abstract Better understanding of the physical drivers sufficiently realistic representation human heat stress is crucial for improving prediction and enhancing preparedness. Wet‐bulb globe temperature (WBGT) a standard metric workplace stress; however, its calculation involves complex parameterizations radiative convective energy exchange, making it difficult to understand driving mechanisms behind WBGT changes. To address this issue, we introduce sensitivity framework analytically evaluate WBGT's response meteorological input By examining form coefficients, gain insights into interactive effects multiple environmental parameters in controlling WBGT. Given constant wind solar radiation, natural wet‐bulb black temperatures change at same rate direction as wet‐ dry‐bulb temperatures, despite considerable differences their absolute values. The framework, while having state‐dependent can be linearized, transforming linear combination temperature, specific humidity, surface pressure, terms representing radiation effects. These explicit mathematically tractable relations between more intuitively understandable variables enable leveraging established theories methods We apply regional scaling with global warming extreme synoptic events. also provides customizable approach develop locally tuned approximations WBGT, clear expectations regarding magnitude induced biases. It used diagnose sources biases existing simplified approximations.

Temperature-Responsive Bottlebrush Polymers Deliver a Stress-Regulating Agent In Vivo for Prolonged Plant Heat Stress Mitigation

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(8), P. 3346 - 3358

Published: Feb. 14, 2023

Anticipated increases in the frequency and intensity of extreme temperatures will damage crops. Methods that efficiently deliver stress-regulating agents to crops can mitigate these effects. Here, we describe high aspect ratio polymer bottlebrushes for temperature-controlled agent delivery plants. The foliar-applied bottlebrush polymers had near complete uptake into leaf resided both apoplastic regions mesophyll cells surrounding vasculature. Elevated temperature enhanced vivo release spermidine (a agent) from bottlebrushes, promoting tomato plant (Solanum lycopersicum) photosynthesis under heat light stress. continued provide protection against stress at least 15 days after foliar application, whereas free did not. About 30% ∼80 nm short ∼300 long entered phloem moved other organs, enabling heat-activated phloem. These results indicate ability encapsulated relief when triggered by long-term plants potential manage pathogens. Overall, this temperature-responsive platform provides a new tool protecting climate-induced yield loss.

A framework to link climate change, food security, and migration: unpacking the agricultural pathway

Population and Environment, Journal Year: 2024, Volume and Issue: 46(1)

Published: March 1, 2024

Abstract Researchers have long hypothesized linkages between climate change, food security, and migration in low- middle-income countries (LMICs). One such hypothesis is the “agricultural pathway,” which postulates that negative change impacts on production harm livelihoods, triggers rural out-migration, internally or abroad. Migration thus an adaptation to cope with of bolster livelihoods. Recent evidence suggests agriculture pathway a plausible mechanism explain climate-related migration. But direct causal connections from livelihood loss out-migration yet be fully established. To guide future research climate-food-migration nexus, we present conceptual framework outlines components underpinning agricultural LMICs. We build established environmental-migration frameworks informed empirical deepened our understanding complex human-environmental systems. First, provide overview its connection mobility literature. then outline primary as they pertain LMIC contexts, highlighting current gaps challenges relating pathway. Last, discuss possible directions for nexus. By complex, multiscale, interconnected underpin pathway, unpacks multiple currently lie hidden hypothesis.
