AGU Advances, 2023 Studies of the impacts of solar geoengineering have mostly ignored tropospheric chemistry. By decreasing the sunlight reaching Earth's surface, geoengineering may help mitigate anthropogenic climate change, but changing sunlight also alters the rates of ...

The Radiative Feedback of the First Cosmological Objects [PDF]
The Astrophysical Journal, 2000 In hierarchical models of structure formation, an early cosmic UV background (UVB) is produced by the small (T_vir < 10^4 K) halos that collapse before reionization. The UVB at energies below 13.6eV suppresses the formation of stars or black holes inside small halos, by photo-dissociating their only cooling agent, molecular H2.

ClimKern v1.2: a new Python package and kernel repository for calculating radiative feedbacks [PDF]
Geoscientific Model DevelopmentClimate feedbacks are a significant source of uncertainty in future climate projections and need to be quantified accurately and robustly. The radiative kernel method is commonly used to efficiently compute individual climate feedbacks from climate model

A global radiative‐convective feedback
Geophysical Research Letters, 1994 We have investigated the sensitivity of the intensity of convective activity and atmospheric radiative cooling to radiatively thick upper‐tropospheric clouds using a new version of the Colorado State University General Circulation Model. The model includes a bulk cloud microphysics scheme to predict the formation of cloud water, cloud ice, rain, and ...

Quantifying climate feedbacks in polar regions
Nature Communications, 2018 Estimating the magnitude of radiative and non-radiative feedbacks is key for understanding the climate dynamics of polar regions. Here the authors propose an inclusive methodology to quantify the influence of all those feedbacks, stimulating more ...

Dynamic vegetation highlights first-order climate feedbacks and their dependence on the climate mean state [PDF]
Earth System DynamicsWe investigate how first-order albedo and water vapor radiative feedbacks are triggered by climate-vegetation interactions using mid-Holocene and pre-industrial climate simulations.

Revisiting the Impact of Sea Salt on Climate Sensitivity
Geophysical Research Letters, 2020 Recent laboratory and field studies point to an increase of sea salt aerosol (SSA) emissions with temperature, suggesting that SSA may lower climate sensitivity.

Explaining Forcing Efficacy With Pattern Effect and State Dependence
Geophysical Research Letters, 2023 The magnitude of global surface temperature change in response to unit radiative forcing depends on the type and magnitude of forcing agent—a concept known as a “forcing efficacy.” However, the mechanisms behind the forcing efficacy are still unclear. In

Global warming due to loss of large ice masses and Arctic summer sea ice
Nature Communications, 2020 The disintegration of cryosphere elements such as the Arctic summer sea ice, mountain glaciers, Greenland and West Antarctica is associated with temperature and radiative feedbacks.

Geophysical Research Letters, 2023 Global greenhouse gas forcing and feedbacks are the primary causes of climate change but have limited direct observations. Here we show that continuous, stable, global, hyperspectral infrared satellite measurements (2003–2021) display decreases in ...
