No trends in spring and autumn phenology during the global warming hiatus

Nature Communications, 2019
A global warming hiatus occurred during 1998 and 2012 but its effects on phenology are unclear. Here the authors examine the trends in spring and autumn phenology in the northern hemisphere and the effects of the warming hiatus and show that phenology ...

Metastability of Northern Hemisphere Teleconnection Modes

Journal of the Atmospheric Sciences, 2015
Abstract This study applies a finite-element, bounded-variation, vector autoregressive method to assess midtropospheric flow regimes characterized by regime switches between metastable states. The flow is assessed in reanalysis data from three different reanalysis sets assimilating surface data only; surface and upper-air data; and ocean,

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

Ecography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Mid-Holocene Intertropical Convergence Zone migration: connection with Hadley cell dynamics and impacts on terrestrial hydroclimate [PDF]

Climate of the Past
This study investigates the multiple changes of the Hadley cell (HC) in response to the northward migration of the Intertropical Convergence Zone (ITCZ) and their combined influence on the terrestrial hydrological cycle during the mid-Holocene, using ...

Enabling a Circular Water Transition: Identifying Governance Pathways for Wastewater Reuse

Environmental Policy and Governance, EarlyView.
ABSTRACT Over 80% of the world's wastewater is discharged untreated, making reuse a widely underutilised strategy for addressing water scarcity. Due to the complexity of implementing water reuse systems, supportive governance conditions are required to steer this process and overcome barriers.

Phase‐Locked Rossby Wave‐4 Pattern Dominates the 2022‐Like Concurrent Heat Extremes Across the Northern Hemisphere

Geophysical Research Letters
Concurrent heat extremes (CHEs) are becoming increasingly common in the mid‐high latitudes across the Northern Hemisphere (NH), underscoring the need to comprehend their spatiotemporal characteristics and underlying causes. Here we reveal a phase‐locking

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.
