Quantifying Climate Feedbacks Using Radiative Kernels

, 2008
The extent to which the climate will change due to an external forcing depends largely on radiative feedbacks, which act to amplify or damp the surface temperature response.

The CXCL5/CXCR2 Axis Attenuates Ferroptosis in Intrahepatic Cholangiocarcinoma Through the Positive Feedback Loop Between PTGS2 Transcriptional Activation and Neutrophil Recruitment

Advanced Science, EarlyView.
The CXCL5/CXCR2 axis directly inhibits ferroptosis in ICC cells by activating the NF‐κB/PTGS2 pathway. Meanwhile, the CXCL5/CXCR2 axis recruits N2 TANs, and the activated PTGS2 promotes the secretion of TNF‐α from the recruited N2 TANs via the CCL2/CCL7/CCR2 pathway, thereby activating the NF‐κB/PTGS2 axis and forming a positive feedback loop, which ...

Contrasting dynamics of past climate states and critical transitions via dimensional analysis

Scientific Reports
While past major climate transitions can be unequivocally identified, understanding of underlying mechanisms and timescales remains limited. We employ a dimensional analysis of benthic stable isotope records across different timescales to uncover how ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Evaluating the Role of Kernel Choice on Radiative Feedback Estimates

Geophysical Research Letters
Radiative feedbacks are important for understanding climate sensitivity, yet estimates vary widely across climate models. Feedbacks are often computed using the radiative kernel technique, which uses pre‐calculated radiative sensitivities (kernels ...

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

Advanced Science, EarlyView.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Including climate feedbacks in regional water resource assessments [PDF]

, 2011
Two important changes to the meteorological conditions can occur as a result of a change in the landsurface state: the precipitation can change (Koster et al, 2004, Wang et al, 2007) and the evaporative demand can change (Ek and Holtslag, 2004 ...
