Atlantic overturning inferred from air-sea heat fluxes indicates no decline since the 1960s
Published 2025-01-01“…Understanding past AMOC changes has relied on proxies, most notably sea surface temperature anomalies over the subpolar North Atlantic. Here, we use 24 Earth System Models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) to demonstrate that these temperature anomalies cannot robustly reconstruct the AMOC. …”

Solar EUV‐Enhancement and Thermospheric Disturbances
Published 2021-12-01“…Abstract The increase of energetic electromagnetic flux during solar flares and particle precipitation during geomagnetic activity are among the most important sources of neutral density disturbances to the Earth's thermosphere. However, disentangling the role of X and EUV radiation during solar flares is difficult due to the rarity of sufficiently isolated EUV‐enhancements. …”
