چکیده
Abstract Compound climate extremes (CCEs) can have significant and persistent environmental impacts on ecosystems. However, knowledge of the occurrence CCEs beyond past ~ 50 years, hence their ecological impacts, is limited. Here, we place widespread 2015–16 mangrove dieback more recent 2020 inland native forest events in northern Australia into a longer historical context using locally relevant palaeoclimate records. Over centuries, multiple occurrences analogous antecedent coincident conditions associated with event were identified this compilation. rising sea level—a key condition—over three decades prior to unprecedented 220 years. Similarly, forests savannas was multi-decadal wetting trend followed by longest most intense drought 250 coupled temperatures. While many communities may experienced addition new stressors varying aspects global change exceed thresholds resilience. Palaeoclimate compilations provide much-needed term better assess frequency changes some types impacts.

Recent climate extremes alter alpine lake ecosystems.
Here, we show that alpine lake ecosystems are responsive to interannual variation in climate, based on long-term limnological and meteorological data from the Canadian Rockies. In the 2000s, in years with colder winter temperatures, higher winter snowfall, later snowmelt, shorter ice-free seasons, and dryer summers, relative to the 1990s, alpine lakes became clearer, warmer, and mixed to deeper...

15 صفحه اولTree Rings Show Recent High Summer-Autumn Precipitation in Northwest Australia Is Unprecedented within the Last Two Centuries
An understanding of past hydroclimatic variability is critical to resolving the significance of recent recorded trends in Australian precipitation and informing climate models. Our aim was to reconstruct past hydroclimatic variability in semi-arid northwest Australia to provide a longer context within which to examine a recent period of unusually high summer-autumn precipitation. We developed a...
