Temperature and precipitation

5. Warm Arctic−cold Siberia: comparing the recent and the early 20th-century Arctic warmings

6. Projected changes in the Asian-Australian monsoon region in 1.5°C and 2.0°C global-warming scenarios

"There is high confidence in projected increases to mean and extreme surface temperatures over AAMR, as well as more-frequent persistent daily temperature extremes over East Asia, Australia and northern India with an additional 0.5°C warming, which are likely to occur. Mean and extreme monsoon precipitation amplify over AAMR, except over Australia at 1.5°C where there is uncertainty in the sign of the change. Persistent daily extreme precipitation events are likely to become more frequent over parts of East Asia and India with an additional 0.5°C warming. There is lower confidence in projections of precipitation change than in projections of surface temperature change. These results highlight the benefits of limiting the global-mean temperature change to 1.5°C above pre-industrial, as the severity of the above effects increases with an extra 0.5°C warming."

7. Assessment of short- and long-term memory in trends of major climatic variables over Iran: 1966–2015

8. Evidence that global evapotranspiration makes a substantial contribution to the global atmospheric temperature slowdown

Climate forcings and feedbacks

18. Comprehensive Assessment of Global Surface Net Radiation Products and Uncertainty Analysis

19. Climate response to negative greenhouse gas radiative forcing in polar winter

"We find, using a fully coupled Earth system model, that the underlying surface warms despite the GHG addition exerting negative ERF and cooling the troposphere in the vicinity of the GHG increase. This unique radiative forcing and thermal response is facilitated by the high stability of the polar winter atmosphere, which inhibits thermal mixing and amplifies the impact of surface radiative forcing on surface temperature. These findings also suggest that strategies to exploit negative ERF via injections of short-lived GHGs into inversion layers would likely be unsuccessful in cooling the planetary surface."

20. Predicting decadal trends in cloud droplet number concentration using reanalysis and satellite data

21. How well can we represent the spectrum of convective clouds in a climate model? Comparisons between internal parameterization variables and radar observations

26. Quantifying anthropogenic dust emissions


27. Explaining CO2 fluctuations observed in snowpacks

28. Irrigation as a potential driver for anomalous glacier behaviour in High Mountain Asia

"Using a regional climate model, in combination with a moisture-tracking model, we show that the increase in irrigation intensity in the lowlands surrounding HMA, particularly in the Tarim basin, can locally counter the effects of global warming on glaciers in Kunlun Shan, and parts of Pamir and northern Tibet, through an increase in summer snowfall and decrease in net radiance. Irrigation can thus affect the regional climate in a way that favours glacier growth, and future projections of glacier melt, which may impact millions of inhabitants surrounding HMA, will need to take into account predicted changes in irrigation intensity."

29. Increased West Antarctic and unchanged East Antarctic ice discharge over the last 7 years

"Using an optimized flux gate, ice discharge from Antarctica is 1929?±?40 Gigatons per year (Gt?yr−1) in 2015, an increase of 36?±?15?Gt?yr−1 from the time of the radar mapping. Flow accelerations across the grounding lines of West Antarctica's Amundsen Sea Embayment, Getz Ice Shelf and Marguerite Bay on the western Antarctic Peninsula, account for 88?% of this increase. In contrast, glaciers draining the East Antarctic Ice Sheet have been remarkably constant over the period of observation. Including modeled rates of snow accumulation and basal melt, the Antarctic ice sheet lost ice at an average rate of 183?±?94?Gt?yr−1 between 2008 and 2015. The modest increase in ice discharge over the past 7 years is contrasted by high rates of ice sheet mass loss and distinct spatial patters of elevation lowering. The West Antarctic Ice Sheet is experiencing high rates of mass loss and displays distinct patterns of elevation lowering that point to a dynamic imbalance."

Atmospheric and oceanic circulation

43. Does Southern Ocean surface forcing shape the global ocean overturning circulation?

44. Forced decadal changes in the East Asian summer monsoon: the roles of greenhouse gases and anthropogenic aerosols

"Furthermore, the experiments with separate forcings indicate that GHG and AA forcing dominate different parts of the SFND pattern. In particular, changes in GHG increase precipitation over southern China, whilst changes in AA dominate in the drought conditions over northern China. Increases in GHG cause increased moisture transport convergence over eastern China, which leads to increased precipitation. The AA forcing changes weaken the EASM, which lead to divergent wind anomalies over northern China and reduced precipitation."

Other papers

85. Total ozone trends from 1979 to 2016 derived from five merged observational datasets – the emergence into ozone recovery

"This paper commemorates the 30-year anniversary of the initial signing of the Montreal Protocol (MP) on substances that deplete the ozone layer. The MP is so far successful in reducing ozone-depleting substances, and total ozone decline was successfully stopped by the late 1990s. Total ozone levels have been mostly stable since then. In some regions, barely significant upward trends are observed that suggest an emergence into the expected ozone recovery phase."

86. Holocene lowering of the Laurentide ice sheet affects North Atlantic gyre circulation and climate

"The climatic effects of the Laurentide ice sheet lowering during the Holocene are restricted to the North Atlantic sector. Thus, topographic forcing is unlikely to have played a major role in the 8.2 ka event and had only a small effect on Holocene climate change compared to the effects of changes in greenhouse gases, insolation and ice sheet meltwater."
