A warm climate is more sensitive to changes in atmospheric CO2

It is well-established in the scientific community that increases in atmospheric CO2 levels result in global warming, but the magnitude of the effect may vary depending on average global temperature. A new study, published ...

Location of upwelling in Earth's mantle discovered to be stable

A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: beneath Africa and the Central Pacific. More importantly, Clinton Conrad, Associate ...

Can we solve the riddle of the coral reef halos?

Coral reefs worldwide are threatened by a variety of human impacts. Fishing is among the most pressing threats to reefs, because it occurs on most reef systems and fundamentally alters food webs. Meanwhile, observing coral ...

Sea-level rise drives shoreline retreat in Hawaii

Sea-level rise (SLR) has been isolated as a principal cause of coastal erosion in Hawaii. Differing rates of relative sea-level rise on the islands of Oahu and Maui, Hawaii remain as the best explanation for the difference ...

Solar wind samples suggest new physics of massive solar ejections

A new study led by the University of Hawai'i (UH) at Mānoa has helped refine understanding of the amount of hydrogen, helium and other elements present in violent outbursts from the Sun, and other types of solar "wind," ...

Lunadong fossils support theory of earlier dispersal of modern man

(Phys.org) —Scientists are now considering the possibility that the exodus of modern man from Africa may have been earlier than 60,000 years ago as traditionally thought. Christopher Bae, a paleoanthropologist at UH Mānoa, ...

Elusive atmospheric wave detected during Tonga volcanic eruption

The catastrophic eruption of the Hunga Tonga–Hunga Haʻapai volcano in 2022 triggered a special atmospheric wave that has eluded detection for the past 85 years. Researchers from the University of Hawaiʻi at Mānoa, Japan ...
