Summary: Since the Paris Agreement, there has been a focus on the 1.5°C and 2°C maximum global warming targets. However, there is no formal definition of the pre-industrial temperature baseline for these targets. This study evaluates nineteenth-century baseline temperatures using instrumental observations and climate reconstructions. The findings suggest that there may be an overestimation of nineteenth-century temperatures, which could reduce the probability of achieving the Paris targets.

Summary: The Early 20th Century Warming in the northern high latitudes was comparable in magnitude to the present-day warming, but occurred at a time when the growth in atmospheric greenhouse gases was significantly less than in the last 40 years. The causes of ETCW remain a matter of debate, with a combination of internal variability and external natural and human impacts likely playing a role in this climate anomaly.

Summary: The suppressed late-20th Century warming seen in CMIP6 is not only caused by a stronger aerosol forcing, but also by weaker greenhouse gas forcing and differences in climate sensitivity between CMIP5 and CMIP6 ensemble. This leads to stronger aerosol cooling over 1960-1990 and stronger greenhouse gas induced warming from 1990, returning the warming post-2000 toward the observed level.

Summary: This study examines the influence of urbanization on local atmospheric moisture under global warming in China. The findings indicate significant declines in atmospheric humidity, forming an 'Urban Dry Island' (UDI). The observed UDI is caused by global warming, urban heat island effect, and reduction in local evapotranspiration and water vapor supplies. The magnitude and frequency of UDI are more pronounced in humid regions compared to arid regions due to differences in background climate and vegetation characteristics. Restoring the evapotranspiration power of urban ecosystems is crucial in mitigating the negative effects of UDI and UHI.

Summary: Vienna was an important center of informal urbanization in 20th-century Europe, and our long-term study shows the remarkable scale and persistence of informal settlements in the city. These settlements not only shaped Vienna's residential areas but also influenced planning instruments and authorities. Studying Vienna's informal urbanization contributes to a better understanding of Northern formality and adds to the growing number of long-term studies on informal urbanization. Additionally, it demonstrates the possibility of reconstructing settlement patterns even before the era of Google Earth, given the necessary source material and technical capabilities.

Summary: This study investigates the changes in atmospheric aridity in China over recent decades and quantifies the effects of urbanization on these changes. The results show that most parts of China have experienced an intensification of atmospheric aridity since the 1970s, especially in urban areas with higher levels of urbanization. It is estimated that urbanization contributed to more than 30% of the total increases in atmospheric aridity in urban core areas.

Summary: The shape of the wet-bulb temperature (T-W) frequency distribution tail affects the increase rate of extreme T-W threshold exceedances. Non-Gaussian T-W distribution tails are found globally, and locations with shorter warm tails are projected to see a faster increase in extreme T-W days. The asymmetry in specific humidity distribution is more correlated with T-W tail shape than temperature, indicating that humidity plays a stronger role in future changes to T-W extremes.

Summary: Croplands have a significant impact on land surface temperature, with general daytime warming and nighttime cooling observed. However, the effects vary greatly by location and season, with nearly half of crop-dominated lands showing daytime cooling and/or nighttime warming on a per-pixel basis. Different countries also experience varying temperature changes due to the size of their cropland areas and local climate effects.

Summary: Climate warming is expected to enhance forest growth in cold-limited biomes while triggering reductions in drought-limited biomes. However, the influence of temperature and drought on tree growth varies across different biomes and elevation gradients. The relationship between tree growth and minimum temperatures weakened while the drought-growth relationship strengthened, with differences observed across biomes and elevation gradients. Temperature controls on forest growth are relaxing as the climate warms, while drought is becoming a more significant constraint for tree growth.

Summary: The East/Japan Sea is a natural laboratory for studying global Meridional Overturning Circulation (MOC) changes. Investigations into winter sea surface temperature (SST) variations are important for characterizing and predicting the East Sea MOC. However, global SST products need to be corrected and optimized for local conditions. A warm bias in cold SSTs was identified in three SST products, and a correction method incorporating Argo float data was suggested. The correction method significantly reduced biases and improved SST data quality.

Summary: The rate of surface warming in cities exceeds that in rural areas, but urban greening can partly offset enhanced urban warming that is driven by climate change and urban expansion. Based on the analysis of satellite land surface temperature data, it is found that warming trends in cities are influenced by both climate processes and urbanization. The average surface warming trend in the urban core of city clusters worldwide is higher than that in rural background, and background climate change is the largest contributor. In city clusters in China and India, urban expansion also plays a significant role. Additionally, evidence of urban greening in some European cities is found, which helps mitigate background surface warming.

Summary: Climate warming has accelerated the spring phenology of many plant species by increasing heat accumulation, but delayed phenophases have been observed due to insufficient chilling. The study compared the effects of preseason chill and heat accumulation on leaf unfolding dates of four deciduous woody species in temperate and subtropical regions of China. Results showed higher chilling requirements and shorter chilling periods in temperate regions, while plants in subtropical regions needed higher forcing temperatures for leaf unfolding. The study also found a significant increase in heat accumulation at most sites, with only one site showing an increase in chill accumulation.

Summary: The study found that 8 out of 14 temperate woody species exhibited significantly different relationships between chilling accumulation and heat requirement in two different winter seasons. Using the chilling model from the first year to simulate spring events in the second year resulted in large uncertainties, with root-mean-square errors ranging from 1.3 to 9.9 days. Additional chilling models were found to improve the phenological simulation by reducing RMSE by 0.1-3.7 days for 10 species.

Summary: This study examines the consistency of breakpoints and adjustments in the homogenized GHCN dataset and finds significant inconsistencies. Some breakpoints correspond to documented station history metadata events, but most breakpoints do not have any associated events. Therefore, while the Pairwise Homogenization Algorithm (PHA) remains a useful tool, many of the adjustments applied to the GHCN dataset may be spurious.

Summary: This study presents a d(13)C record from a Tridacna gigas shell in the South China Sea, revealing seasonal and interannual cycles, as well as a long-term decreasing trend. The research investigates environmental factors affecting d(13)C at different time scales and suggests that high d(13)C values in the juvenile stage can be attributed to C-13 enrichment and preferential C-12 sequestration. On the interannual scale, both internal and external processes and the El Nino-La Nina event affect d(13)C, while seasonal changes are primarily influenced by photosynthesis and respiration of symbiotic zooxanthellae.

Summary: Since 2007, the IPCC has concluded that post-1950s global warming is mostly human-caused based on the comparison between global climate model hindcasts and global surface temperature estimates. However, Connolly et al. argued that this detection and attribution method is highly dependent on the choice of Total Solar Irradiance and surface temperature datasets, leaving uncertainty as to whether the observed warming is predominantly human-induced or natural.

Summary: Crop phenology has measurable impacts on soil surface properties, biophysical processes, and climate feedbacks at local or regional scales. The response of surface biophysical processes to climate feedbacks as affected by sowing date in winter wheat croplands, especially during winter dormancy, has been overlooked. The study demonstrates that the sowing date affects the dynamics of leaf area index, surface energy balance, and canopy temperature, with earlier sowing resulting in higher LAI and different temperature responses during dormancy and active growth periods.
