Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball Earth events, indicating that liquid-water refugia existed somewhere on the surface. We examine the potential for refugia at the coldest time of a snowball event, before CO2 had …
Land carbon sinks are responsible for removing about a quarter of anthropogenic CO2 emissions, and make up approximately half of total global carbon sinks. Uncertainty in the response of land carbon sinks to climate and changing atmospheric CO2 are …
Terrestrial processes control land-to-atmosphere fluxes of water, energy, and carbon and are also influenced by climate. Feedbacks in the land-atmosphere coupled system can therefore potentially modulate changes in land surface water fluxes. Prior …
Both canonical theory and climate model simulations predict an increase in globally averaged precipitation with warming from radiative forcing. However, terrestrial processes control surface water and energy fluxes, and therefore can impact surface …
Isoprene is the most significant non-methane hydrocarbon by total emissions and an important control on the tropospheric oxidative capacity. In the atmosphere, isoprene is oxidized by the hydroxyl radical (OH) on the order of hours depending on local …
Plant physiological responses to rising CO2 have been shown to contribute to increasing extreme heat; but their impacts on co-occurrences of high heat and humidity have not been assessed previously. Since heat stress depends on both, reductions in …
Recent observations show anomalously high methane growth in 2020, which has been attributed to increased wetland emissions and decreased OH from lower COVID-19 nitrogen oxide (NOx) emissions. NOx is not the only species that affects OH-isoprene, the …
Changes in blue water, which is the total supply of fresh water available for human extraction over land, are quite closely related to changes in runoff or equivalently precipitation minus evaporation, P?E{\$}{\$} P-E {\$}{\$}. This article examines …
