"We examined a future change of Köppen–Geiger climate classification zones in central Europe in the 21st century using the high?resolution (10 km) bias?corrected simulations of two regional climate models following the IPCC SRES A1B emission scenario. Temperate oceanic climate (Cfb) will remain the dominant climate type in central Europe but it will extent into higher altitudes and replace boreal or colder climate types that will practically vanish by the end of the 21st century. There is a risk of large?scale expansion of humid subtropical (Cfa) climate in lower altitudes where 20–50% of population lives nowadays. In the end of the century the majority of arable land and permanent crops areas will be in the Cfa zone. A growing occurrence of Cfa?like or Mediterranean climate?like (Csa) years will reach up to 50% at some locations where 1.4 million people live today. Almost all agriculturally important areas and two thirds of the current population will be exposed to the occurrence of Cfa? and Csa?like years at least once in 10 years which may result into a lower production of rain?fed crops as it was the case of of Cfa? and Csa?like years of 2000, 2012 and 2015."
2. Ground thermal and geomechanical conditions in a permafrost-affected high-latitude rock avalanche site (Polvartinden, northern Norway) (open access)
"It is likely that permafrost in and near the failure zone is presently subject to degradation. This degradation, in combination with the extreme warm year antecedent to the rock failure, is seen to have played an important role in the detaching of the Signaldalen rock avalanche."

3. When do Indians feel hot? Internet searches indicate seasonality suppresses adaptation to heat (open access)
"State-level heat thresholds ranged from 25.9 °C in Madhya Pradesh to 31.0 °C in Orissa. Local adaptation was found to occur at state level: the higher the average temperature in a state, the higher the heat threshold; and the higher the intra-annual temperature range (warmest minus coldest month) the lower the heat threshold."

13. Warming drives higher rates of prey consumption and increases rates of intraguild predation
Study on dragonfly larvae: "Warming increased feeding rates by 42% on average across species but had no effect on activity rate. The magnitude of change in feeding rate was positively correlated with the maximum temperatures species experience across their ranges. Lastly, warming increased rates of IGP twofold, however, species’ behavioral responses alone were not predictive of their susceptibility to become IG prey of other larvae at warmer temperatures."

17. Phytoplankton Increases Induced by Tropical Cyclones in the South China Sea During 1998–2015
"We found that both tits and flycatchers advanced laying in response to spring warming, but resident tit populations advanced more strongly in relation to temperature increases than migratory flycatchers. These different temperature responses have already led to a divergence in laying dates between tits and flycatchers of on average 0.94 days per decade over the current study period. Interestingly, this divergence was stronger at lower latitudes where the interval between tit and flycatcher phenology is smaller and winter conditions can be considered more favorable for resident birds."

"Our findings do not support the hypothesis that future increases in atmospheric [CO2] will, by itself, promote woody plant recruitment in eucalypt-dominated temperate grassy woodlands."

39. The early 20th century warming: Anomalies, causes, and consequences
"Attribution studies estimate that about a half (40–54%; p > .8) of the global warming from 1901 to 1950 was forced by a combination of increasing greenhouse gases and natural forcing, offset to some extent by aerosols. Natural variability also made a large contribution, particularly to regional anomalies like the Arctic warming in the 1920s and 1930s."
40. Growing Land?Sea Temperature Contrast and the Intensification of Arctic Cyclones
"By comparing statistics for years with high land?sea thermal contrast against years with low, we demonstrate that storms over the Arctic Ocean will likely become more frequent and more dynamically intense as the climate warms, increasing the risk to shipping and other human activities."

57. A systematic wavelet-based exploratory analysis of climatic variables
"Shorter-term variations in global surface temperature are associated with internally generated natural climate variability and external climate forcings, while longer-term variations are strongly related to human-induced changes only. In this respect, a long-term component of the net radiative forcing of human activities longer than 30 years displays a statistically significant relationship with global warming and cooling periods identified in the climate change literature."

59. Spatially Resolved Isotopic Source Signatures of Wetland Methane Emissions
"Concentrations of methane are increasing in the atmosphere. In order to understand the reasons behind such variations, carbon isotopes are used to help identify changes in emission sources and sinks. We present a new global map of the carbon isotope signature associated with wetland methane emissions, the largest global source of methane to the atmosphere. We show how this newly synthesized information can lead to more accurate understanding of the causes of variations in the amount and rate of increase of methane in the atmosphere."

64. Different Global Precipitation Responses to Solar, Volcanic, and Greenhouse Gas Forcings
"For a given global temperature change, the global precipitation change under volcanic forcing is larger than that under solar and GHG forcings. The reason is that the volcanic forcing induces the strongest solar irradiance change in the wet tropics. Among the three forcings we examined, the GHG forcing excites the strongest high?latitude warming, especially the Arctic amplification of global warming. There is no Arctic amplification of temperature decrease under the volcanic forcing?induced global cooling. The volcanic forcing weakens the Intertropical Convergence Zone and reduces precipitation. The results suggest that while volcanic eruptions can reduce precipitation, they do not mitigate the Arctic amplification of temperature increase under the GHG?induced warming."

68. Accelerating glacier mass loss on Franz Josef Land, Russian Arctic
"Mass loss from FJL doubled between 2011 and 2015 compared to 1953–2011/2015, increasing from a rate of −2.18 ± 0.72 Gt yr−1 to −4.43 ± 0.78 Gt yr−1. This 2011−2015 rate indicates an acceleration in ice loss from that observed in 2003–2009 by multiple studies using ICESat and GRACE. Glacier thinning rates are spatially highly variable. We observe glacier thinning rates of up to 10?m per year, and in general we see a trend of increased thinning from the NE towards the SW. Glacier retreat is widespread and has led to the creation of at least one new island. Historically, ice wastage from FJL is thought to have been relatively small, but accelerating ice loss may be the new normal for this archipelago in a warming Arctic."
