HadCRUT5, the new version of the Met Office Hadley Centre/Climatic Research Unit global surface temperature dataset from 1850 to 2018, has extended and improved the previous temperature record.

When Will the Next Failure Be?
Unprecedented images of fracture networks in laboratory scale experiments mixed with machine learning algorithms help predict the timing of the next failure.
Thawing Permafrost May Cause Streams to Cool
Permafrost thawing associated with climate warming increases contributions to streamflow by deeper, cooler groundwater flow paths, which may result in lower summer stream temperatures.
Hunting the Source of Deccan Traps Volcanism Using Seismic Waves
Seismic velocity patterns beneath the Deccan Traps region in western India reveal its volcanic history.
Rainfall Change with Warming More Consistent than Anticipated
Dew point temperature better explains precipitation change with warming than temperature itself, and the relation is more spatially coherent than previously thought.
Global Warming Intensifies Turbulence Over Northern Eurasia
A significant increasing trend of turbulence in upper atmosphere over northern Eurasia is attributed to intense anthropogenic activities.
Robot Measures Air-Sea Carbon Dioxide Exchange in Southern Ocean
Unique air and ocean surface observations of the Southern Ocean from a 22,000 km, 196-day circumnavigation around Antarctica by an Uncrewed Surface Vehicle.
Why are Earthquakes on the San Andreas Seasonally Modulated?
There is growing evidence that some earthquakes occur seasonally but also that water loading cannot explain these observations.
Wind Stress is not the Ceiling of Momentum Flux to the Ocean
The ocean is mainly driven by wind stress, but simultaneous observations show that the gain of momentum flux by the ocean can be larger than the wind stress due to the influence of ocean waves.
The Failure of Physics-Based Earthquake Forecasting Models
Spatial clustering of aftershocks explains why simple statistical models often outperform complex physics‐based earthquake forecasting models even if the physical mechanisms are correctly modeled.
