Plants may run out of time to grow under ongoing climate change

Corn at Waimanalo Research Station Open House

A key potential “benefit” of global warming — namely, that plants at northern latitudes will thrive in a warmer world — is challenged by a new study released by University of Hawai’i scientists. The prevailing assumption ignores the fact that plants in the North will remain limited by solar radiation, curbing positive effects of warming and additional CO2 availability. In …

[VIDEO] How to train your coral

Coral

Scientists warn extreme sea temperatures could cause a “historic” coral reef die-off around the world over, following a massive coral bleaching event in fall 2014 in the North Pacific. A huge swathe of the Pacific was affected, including the Northern Marianas Islands, Guam, the Republic of the Marshall Islands, Hawai‘i, and Kiribati. Some areas recorded serious bleaching for the first time, and …

New research finds oceanic microbes behave in synchrony across ocean basins

Researchers from UH Mānoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats – the nutrient-rich waters off California and the nutrient-poor waters north of Hawai‘i. Furthermore, in each location, the dominant photoautotrophs – light-loving bacteria that need solar energy to help them photosynthesize …

Climate researchers discover El Nino’s fueling effect on intense hurricanes

Typhoon Vicente

El Niño, the abnormal warming of sea surface temperatures in the Pacific Ocean, is a well-studied tropical climate phenomenon that occurs every few years. It has major impacts on society and Earth’s climate – inducing intense droughts and floods in multiple regions of the globe. Further, scientists have observed that El Niño greatly influences the yearly variations of tropical cyclones …

Another human footprint in the ocean: Rising anthropogenic nitrate levels

Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a study published this week in Science showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle. The rate of deposition of reactive nitrogen (i.e., nitrogen oxides …
