The climatic impact of CO2 and other greenhouse gases is usually quantified in terms of radiative forcing, calculated as the difference between estimates of the Earth’s radiation field from pre-industrial and present-day concentrations of these gases. Radiative transfer models calculate that the increase in CO2 since 1750 corresponds to a global annual-mean radiative forcing at the tropopause of 1.82 ± 0.19 W m−2 (ref. 2). However, despite widespread scientific discussion and modelling of the… Expand
Observationally derived rise in methane surface forcing mediated by water vapour trends
Atmospheric methane (CH4) mixing ratios exhibited a plateau between 1995 and 2006 and have subsequently been increasing. While there are a number of competing explanations for the temporal evolutionExpand

Detailed line-by-line radiation transfer calculations, which were performed under different atmospheric conditions for the most important greenhouse gases water vapor, carbon dioxide, methane, and ozone, are presented to assess the CO2 global warming by means of an advanced two-layer climate model and to disclose some larger discrepancies in calculating the climate sensitivity.

Reducing uncertainties in climate models
Implementing accurate calculations of radiative forcing can improve climate projections and provide a straightforward means to substantially reduce uncertainties in model projections of climate change. Expand
Processes shaping the spatial pattern and seasonality of the surface air temperature response to anthropogenic forcing
In the period 1960–2010, the land surface air temperature (SAT) warmed more rapidly over some regions relative to the global mean. Using a set of time-slice experiments, we highlight how differentExpand
Does Surface Temperature Respond to or Determine Downwelling Longwave Radiation?
Downward longwave radiation (DLR) is often assumed to be an independent forcing on the surface energy budget in analyses of Arctic warming and land-atmosphere interaction. We use radiative kernels toExpand
Radiative flux and forcing parameterization error in aerosol‐free clear skies
A dependence on atmospheric conditions, including integrated water vapor, means that global estimates of parameterization error relevant for the radiative forcing of climate change will require much more ambitious calculations. Expand
Contribution of anthropogenic CO2 in China to global radiative forcing and its offset by the ecosystem during 2000–2015
Using global CO2 assimilation data from 2000 to 2015 and a carbon–climate parameterized scheme to analyze anthropogenic carbon emissions and their climatic effects while considering the climate effects of the terrestrial ecosystem carbon sink, the importance of ecosystems on mitigating climate warming is highlighted.

Ozone Depletion Explains Global Warming
Background: The Intergovernmental Panel on Climate Change concludes that anthropogenic greenhouse gases are extremely likely to have been the dominant cause of observed global warming. Depletion ofExpand

Abstract California recently experienced among the worst droughts of the last century, with exceptional precipitation deficits and co-occurring record high temperatures. The dry conditions causedExpand


Radiative forcing by long‐lived greenhouse gases: Calculations with the AER radiative transfer models
A primary component of the observed, recent climate change is the radiative forcing from increased concentrations of long-lived greenhouse gases (LLGHGs). Effective simulation of anthropogenicExpand
Increases in greenhouse forcing inferred from the outgoing longwave radiation spectra of the Earth in 1970 and 1997
This work analyses the difference between the spectra of the outgoing longwave radiation of the Earth as measured by orbiting spacecraft in 1970 and 1997 to provide direct experimental evidence for a significant increase in the Earth's greenhouse effect that is consistent with concerns over radiative forcing of climate.

The climatological record of clear‐sky longwave radiation at the Earth's surface: evidence for water vapour feedback?
An increase in global surface temperature of between 1.4 K and 5.8 K is expected to occur by 2100 due to a doubling of the global concentration of CO2. Associated with this predicted surface warmingExpand
