Ozone depletion-induced climate change following a 50 pc supernova

Ozone in Earth's atmosphere is known to have a radiative forcing effect on climate. Motivated by geochemical evidence for one or more nearby supernovae about 2.6 million years ago, we have…

Atmospheric Convection Plays a Key Role in the Climate of Tidally Locked Terrestrial Exoplanets: Insights from High-resolution Simulations

Using a 3D general circulation model (GCM), we investigate the sensitivity of the climate of tidally locked Earthlike exoplanets, Trappist-1e and Proxima Centauri b, to the choice of a convection…

Habitable zones with an earth climate history model

The most common habitable planets – II. Salty oceans in low-mass habitable planets and global climate evolution

The available models of global climate evolution in habitable earthlike planets do not consider the effect of salt content in oceans, which affects water evaporation. Two distinct categories of such…

Planetary geodynamics and age constraints on circumstellar habitable zones around main sequence stars

Planetary geodynamics may have an important influence over planetary habitability and the boundaries of the circumstellar habitable zone (CHZ) in space and time. To investigate this we use a…

H2O Windows and CO2 Radiator Fins: A Clear‐Sky Explanation for the Peak in Equilibrium Climate Sensitivity

Recent explorations of the state‐dependence of Earth’s equilibrium climate sensitivity (ECS) have revealed a pronounced peak in ECS at a surface temperature of ∼310 K. This ECS peak has been observed…

Global stability properties of the climate: Melancholia states, invariant measures, and phase transitions

For a wide range of values of the intensity of the incoming solar radiation, the Earth features at least two attracting states, which correspond to competing climates. The warm climate is analogous…

Three-dimensional Climate Simulations for the Detectability of Proxima Centauri b

The discovery of a planet orbiting around Proxima Centauri, the closest star to the Sun, opens new avenues for the remote observations of the atmosphere and surface of an exoplanet, Proxima b. To…

How surfaces shape the climate of habitable exoplanets

Large ground- and space-based telescopes will be able to observe Earth-like planets in the near future. We explore how different planetary surfaces can strongly influence the climate, atmospheric…

Transitions across Melancholia States in a Climate Model: Reconciling the Deterministic and Stochastic Points of View.

This Letter studies how stochastically perturbing the parameter controlling the intensity of the incoming solar radiation impacts the stability of the climate and detects transitions between the warm and the snowball state and analyzes the properties of the noise-induced escapes from the corresponding basins of attraction.

On the climate response to zero ozone

Although ozone appears in the Earth’s atmosphere in a small abundance, it plays a key role in the energy balance of the planet through its involvement in radiative processes. Its absorption of solar…

The evolution of habitable climates under the brightening Sun

On water‐dominated planets, warming from increased solar insolation is strongly amplified by the water vapor greenhouse feedback. As the Sun brightens due to stellar evolution, Earth will become…

Increased insolation threshold for runaway greenhouse processes on Earth-like planets

A three-dimensional global climate model is used to show that the insolation threshold for the runaway greenhouse state to occur is about 375 W m−2, which is significantly higher than previously thought and has strong implications for the possibility of liquid water existing on Venus early in its history, and extends the size of the habitable zone around other stars.

Stratospheric Temperature and Radiative Forcing Response to 11-Year Solar Cycle Changes in Irradiance and Ozone

Abstract The 11-yr solar cycle temperature response to spectrally resolved solar irradiance changes and associated ozone changes is calculated using a fixed dynamical heating (FDH) model. Imposed…

Impact of increasing stratospheric water vapor on ozone depletion and temperature change

Using a detailed, fully coupled chemistry climate model (CCM), the effect of increasing stratospheric H2O on ozone and temperature is investigated. Different CCM time-slice runs have been performed…

Transition to a Moist Greenhouse with CO2 and solar forcing

It is shown with three-dimensional aqua-planet simulations that CO2-induced forcing as readily destabilizes the climate as does solar forcing, and that the climate transition cannot be reversed by removing the additional forcing.
