In the context of forecasted climate change scenarios, growth forest tree species at their distribution margin is crucial to adapt current management strategies. Analyses beech (Fagus sylvatica L.) have shown high plasticity, but easternmost populations been rarely studied. To describe response marginal population in far east sites its distribution, we first compiled new ring width chronologies. Then analyzed climate-growth relationships for three Republic Moldova. We observed a relatively rate compared core sites. Our analyses further revealed distinct and significant all climatic variables, assessing time relationship between vapor pressure deficit (VPD) which described how plant responds drought. These results highlight that accumulated water an essential limiting factor this region. conclusion, drought-limited, sensitivity VPD will need be considered future studies update other economic ecologically important species.

The causes of recent hydrological droughts and their future evolution under a changing climate are still poorly understood. Banking on 216-year river flow time series at the Po River outlet, we show that 2022 drought is worst event (30% lower than second worst, with six-century return period), part an increasing trend in severe occurrence. decline summer flows (-4.14 cubic meters per year), which more relevant precipitation decline, attributed to combination changes regime, resulting snow fraction (-0.6% year) snowmelt (-0.18 millimeters day evaporation rate (+0.013 kilometers irrigated areas (100% increment from 1900). Our study presents compelling case where impact change exacerbated by local hydrologic seasonality water use.

Abstract Background The global human footprint has fundamentally altered wildfire regimes, creating serious consequences for health, biodiversity, and climate. However, it remains difficult to project how long-term interactions among land use, management, climate change will affect fire behavior, representing a key knowledge gap sustainable management.

Persistent multiyear drought (MYD) events pose a growing threat to nature and humans in changing climate. We identified inventoried global MYDs by detecting spatiotemporally contiguous climatic anomalies, showing that have become drier, hotter, led increasingly diminished vegetation greenness. The terrestrial land affected has increased at rate of 49,279 ± 14,771 square kilometers per year from 1980 2018. Temperate grasslands exhibited the greatest declines greenness during MYDs, whereas boreal tropical forests had comparably minor responses. With becoming more common, this quantitative inventory occurrence, severity, trend, impact provides an important benchmark for facilitating effective collaborative preparedness toward mitigation adaptation such extreme events.

Abstract. In drought-prone Australia, multi-year droughts have detrimental impacts on both the natural environment and human societies. For responsible water management, we need a thorough understanding of full range variability in how this might change warming world. But research into long-term frequency, persistence, severity Australian is limited. This partly due to length observational record, which short relative timescales hydroclimatic hence may not capture possible variability. Using simulations precipitation over past millennium (850–2000), characterise nature meteorological across Australia include particular focus Murray–Darling Basin (MDB), largest agricultural region Australia. We find that simulated 20th century (1900–2000) are within bounds pre-industrial terms drought intensity, severity, frequency. A tendency for last longer southwestern eastern (including MDB) century, compared with period, suggests an emerging anthropogenic influence, consistent projected rainfall changes these regions. Large volcanic eruptions tend promote drought-free intervals MDB. Model suggest future could be much than what was experienced even without any influence. With addition climate change, favours conditions southern reduced cool-season rainfall, it likely will exceed recent historical experience.
