    Vegetation emits organic vapors which can form aerosols in the atmosphere and influence cloud properties. Here, the authors show observational evidence that warmer temperatures lead to increased emissions of these aerosols in boreal forests which cause surface cooling, demonstrating a negative climate feedback mechanism.

    Sea spray aerosol (SSA) are an important way through which oceans can influence the atmosphere’s radiative properties. Here, the authors present measurements taken over a 42,000 km ship cruise in the Atlantic and Pacific Ocean and show that SSA number concentrations vary over a 24-hour cycle, possibly linked to surface water bubble-bursting dynamics.

    How much the potential intensity of tropical cyclones (TCs) increases in warmer environments is not well known. Here, the authors show that TC rainfall rates have increased by 1.3% per year between 1998 and 2018, a trend that is mainly driven by stronger rainfall in the outer-core region of TCs.

    Satellite observations reveal a significant positive trend in Earth’s energy imbalance, but the contributing drivers have yet to be understood. Here, the authors show that it is exceptionally unlikely that this trend can be explained by internal variability; instead, anthropogenic forcing and feedbacks cause the trend.

    How the Central American mountains influence tropical cyclone (TC) development in the eastern North Pacific is not well understood. Here, the authors use model simulations to show that on a seasonal timescale, these mountains interrupt moisture transport from the Caribbean Sea and as a result, reduce TC activity by up to 35%.

    Many different methods have been developed to forecast climate phenomena like the El Nino-Southern Oscillation (ENSO) which makes a fair comparison of their capabilities crucial. In this perspective, the authors discuss how choices in the evaluation method can lead to an overestimated perceived skill of ENSO forecasts.

    How tropical cyclones have varied in intensity and frequency in the past is not well known as longer records are rare. Here, the authors show that changes in observing practices explain the recorded century scale increase in Atlantic major hurricane frequency, and recent increases are not part of a century-scale trend.

    Despite a ban on ozone depleting substances, ozone depletion during cold winters in the Arctic stratosphere has been increasing in recent decades. Here, the authors show conditions favourable for Arctic ozone depletion could worsen as a response of stratospheric temperature and water to continued release of greenhouse gases.

    Satellite-based estimates of radiative forcing by aerosol–cloud interactions are consistently smaller than those from global models, hampering accurate projections of future climate change. Here, the authors show that the discrepancy can be substantially reduced by correcting sampling biases induced by inherent limitations of satellite measurements.

    It has been suggested that sea surface temperatures in the North Tropical Atlantic exert strong influence on the evolution of the El Nino Southern Oscillation (ENSO). Here, the authors argue that observed statistics are fully consistent with ENSO driving climate variations in the Atlantic and not vice versa.

    The production of chlorofluorocarbons (CFC) was phased-out under the Montreal, but renewed emissions of CFC-11 have been reported recently. Here, the authors present a joint analysis of multiple factors and find that emissions of CFC-11, but also CFC-12 and CFC-113 are higher than expected, indicating renewed emissions.

    The Antarctic Peninsula sees some of the strongest warming of the whole continent over the last decades, the drivers of which are not well known. Here, the authors show that winter sea surface temperature increases in the Tasman sea lead to changes in Southern Ocean storm tracks that in turn warm the Antarctic Peninsula.

    Atmospheric rivers are responsible for much of the poleward water vapour transport in the mid-latitudes and can cause extreme precipitation after landfall. Here, the authors show that ocean fronts and eddies can influence atmospheric rivers and increase the associated precipitation along the North American west coast.

    The regulation of aircraft engine NOx emissions was introduced to improve local air quality and reduce NOx emissions at altitude. Here, the authors find that greater fuel efficiency of aircrafts, and therefore lower CO2 emissions, could be preferable to reducing NOx emissions in terms of the aviation industries future climate impacts.

    Wildfires produce aerosols known to impact the climate, but the wider-reaching effects of this biomass burning are poorly constrained in models. Here the authors use a suite of observations from 12 campaigns around the globe to determine that the values used by most climate models overestimate the contribution of biomass burning aerosols.

    Human emissions are thought to have caused an increase in wildfire risk, but how different emission sources contribute is less well known. Here, the authors show that the increase due to greenhouse gas emissions was balanced by aerosol-driven cooling, an effect that is projected to disappear during the 21st century.

    Many climate models failed to reproduce the eastern Pacific cooling that has been linked to slower warming in the early 20th century. Here, the authors present a feedback mechanism between the tropical Pacific and the Atlantic which contributes to this bias as it further dampens the Pacific cooling response in models.
