A graph I saw in high school appeared to show the Earth breathing. It was a graph that plotted carbon dioxide in the atmosphere over the course of the 20th century and into the 21st. CO2 had risen steadily, and then more rapidly, but it hadn't gone up in a straight line. Each year it had fallen sharply before rising to a new peak, increasing over time in an upwards zig-zag.

Where California's towering Sierra Nevada surrenders to the sprawling San Joaquin Valley, a high-stakes detective story is unfolding. The culprit isn't a person but a process: the mysterious journey of snowmelt as it travels underground to replenish depleted groundwater reserves.

A new AI weather prediction system, Aardvark Weather, can deliver accurate forecasts tens of times faster and using thousands of times less computing power than current AI and physics-based forecasting systems, according to research published in Nature.

According to a predictive model developed by a CNRS researcher and his European colleagues, the microalgae present in peat bogs could offset up to 14% of future CO2 emissions, thanks to their photosynthetic activity. This conclusion was reached by basing the work on in situ experiments and the various predictive scenarios established by the IPCC.

A team of researchers is making final preparations for a trip to Mount Everest in Nepal next month to explore why the ice of one of the mountain's most iconic glaciers is so close to the melting point.

NPL and MSL in New Zealand successfully detected a multitude of earthquakes in the Pacific Ocean using a pioneering detection technique.

Most of the United States' major climate regulations are underpinned by one important document: It's called the endangerment finding, and it concludes that greenhouse gas emissions are a threat to human health and welfare.

Key agreements in the "Law of the River," which encompasses more than 100 years of regulations, laws, court decisions and more focused on managing the Colorado River, are set to expire next year. First established in 1922 as the Colorado River Compact, the guidelines split water management and allocation among seven states.

SummaryWe determine detailed 3-D velocity and anisotropy models of the crust beneath the central segment of the Tanlu fault zone (TLFZ) in east China using hand-picked arrival times of direct waves (Pg, Sg), refracted waves (Pn, Sn), and the Moho reflected waves (PmP and SmS) of local earthquakes recorded at 55 portable seismic stations of our newly deployed TanluArray and 45 Chinese provincial stations. Our results show that the pattern of seismic velocity and anisotropy is in good agreement with surface geological and tectonic features in the study region. Along the TLFZ, obvious low-velocity (low-V) anomalies are visible in the lower crust in the north of the Cangni fault, whereas high-velocity (high-V) anomalies appear in the upper and middle crust. The 1668 Tancheng earthquake (M8.5) and small-to-moderate earthquakes occurred in the high-V zones but underlain by low-V anomalies. The low-V zones may reflect significant effects of fluids derived from hot and wet upwelling flow in the big mantle wedge. Under the Suqian seismic gap, low-V anomalies are clearly imaged in the middle crust, whereas high-V anomalies appear in the lower crust, suggesting the absence of fluids in the deep crust, which could explain why few earthquakes occurred there. The fast velocity direction (FVD) of P-wave azimuthal anisotropy changes with depth. The FVD is parallel with the TLFZ strike in the upper crust in and around the TLFZ, reflecting the strike-slip features of the fault zone. Our results provide new seismic constraints on the structure and tectonic evolution of the TLFZ.
