Rising CO2 levels creating crazy fish

Rising oceanic carbon dioxide (CO2) levels are disrupting a key brain receptor in fish, causing dramatic changes in their brain chemistry, behavior and sensory abilities, say Australian researchers from the ARC Centre of Excellence for Coral Reef Studies. Their work appears in the journal Nature Climate Change. Around 2.3 billion tons of human CO2emissions dissolve […]

Warming climate supercharging parasite lifecycle




Schistocephalus solidus, a parasitic worm that infects fish, has been found to grow much more rapidly at higher temperatures, alarming scientists who warn that warming oceans could see the worm decimate fish populations. The new research into S. solidus’lifecycle has been published in the journalGlobal Change Biology. The work provides some of the first evidence […]

El Niño climate cycle triggering wars




Researchers from Columbia University’s Earth Institute say that El Niño, the periodic climate cycle that boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may account for a fifth of worldwide conflicts during the past half-century. The paper, the first to link a natural global climate cycle […]

Climate change studies vexed by Vesta




Paleoclimate studies, where scientists look into the past to try and understand changes in Earth’s climate, may be a waste of time if astronomers are correct in their theory that relatively minor bodies like the asteroid Vesta can cause chaotic fluctuations in Earth’s orbit. NASA’s Dawn space-probe flew by Vesta last Saturday. The journal Astronomy […]

“Profound” plant water cycle changes add new wildcard to climate change guesstimates




Botanists from Indiana University (IU) and Utrecht University (Netherlands) have discovered that rising carbon dioxide levels over the last 150 years have reduced the density of the pores (known as stomata) that plants use to breathe by 34 percent, dramatically lowering the amount of water vapor the plants release to the atmosphere. Writing about their […]

CO2 “inertia” makes significant climatic disruption inevitable




The first full climate simulation to make predictions out to the year 3000 indicates that even if zero CO2emissions were achieved immediately, the inertia of past carbon dioxide emissions would continue affecting the planet for the next 1000 years. Appearing in the journal Nature Geoscience, the new work is based on best-case, “zero-emissions” scenarios constructed […]
