Satellite Clear‐Sky Observations Overestimate Surface Urban Heat Islands in Humid Cities

Geophysical Research Letters, Journal Year: 2024, Volume and Issue: 51(2)

Published: Jan. 12, 2024

Abstract Satellite‐based thermal infrared (TIR) land surface temperature (LST) is hindered by cloud cover and applicable solely under clear‐sky conditions for estimating urban heat island intensity (SUHII). Clear‐sky SUHII may not accurately represent all‐sky conditions, potentially introducing quantitative biases in assessing islands. However, the differences between SUHIIs their spatiotemporal variations are still poorly understood. Our analysis of over 600 global cities demonstrates that mostly higher than SUHII, particularly summer, daytime, precipitation‐rich regions. Besides, typically exhibits stronger seasonal diurnal contrasts especially located humid These discrepancies can be attributed mainly to increased missing LST data caused enhancement areas. findings highlight tendency observations overestimate providing valuable insights standardizing quantification

Dynamic urban land extensification is projected to lead to imbalances in the global land-carbon equilibrium

Abstract Human-Earth System Models and Integrated Assessment used to explore the land-atmosphere implications of future land-use transitions generally lack dynamic representation urban lands. Here, we conduct an experiment incorporating urbanization in a multisector model framework. We integrate projected non-urban lands from with 2015 2100 at 1-km resolution examine 1 st -order land system, crop production, net primary production that can arise competition over resources. By 2100, extensification could displace 0.1 1.4 million km 2 agriculture lands, leading 22 310 Mt compromised corn, rice, soybean, wheat production. When considering increased corn required meet demands by cut increases yields half. Losses displaced forest, grassland, croplands ranged 0.24 2.24 Gt C yr −1 , potentially increasing emissions 1.19 6.59 CO . Although these estimates do not consider adaptive responses, experiments elucidate individual role sub-sectors would otherwise be masked complexity.

Impacts of warming on outdoor worker well-being in the tropics and adaptation options

One Earth, Journal Year: 2024, Volume and Issue: 7(3), P. 382 - 400

Published: March 1, 2024

Over a billion outdoor workers live in the tropics, where nearly fifth of all hours year are hot and humid enough to exceed recommended safety thresholds for conducting heavy labor. Reviews have focused on heat impacts worker health, well-being, productivity, but synthesis how increase resilience is lacking. Here we assess current future exposure tropics review four bodies literature workers. We also synthesize knowledge about mitigation adaptation uncertainties as well actions that can be taken strengthen resilience. show under an additional 1°C warming, ∼800 million people will areas work should limited over half year. Our provides primary, secondary, tertiary solutions inform policies practices research needed bolster well-being.
