CO2 not to blame for global warming, claims new study that argues global cooling has already begun

Conventional thinking on climate change holds that human emissions of carbon dioxide have been the major contributor to global warming, but an intriguing new study that examined data going back to the Industrial Revolution indicates that chlorofluorocarbons (CFCs) conspiring with cosmic rays are the real culprit. The research, by Professor Qing-Bin Lu at the University […]

Rising CO2 giving fish super-hearing

Ocean acidification is known to negatively impacta wide variety of marine animals, but new research indicates that a huge increase in hearing sensitivity for fish could also be one of the effects. In the new study, published in the Proceedings of the National Academy of Sciences, researchers report on the potential effects of acidification on […]

Biofuels could be made directly from excess CO2 in the atmosphere, say scientists

Researchers at the University of Georgia have found a way to transform carbon dioxide in the atmosphere into a variety of useful industrial products. Their discovery may soon lead to the creation of biofuels made directly from carbon dioxide in the air – one of the major driving forces of global climate change. Details about […]

30ft sea level rise may be unavoidable

Climatologists examining the relationship between sea level and carbon dioxide (CO2) concentrations over the last 40 million years have found that present day greenhouse gas concentrations (around 400 parts per million) have historically been associated with sea levels at least 30 feet above current levels. The study, appearing in Proceedings of the National Academy of […]

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 […]

“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 […]

Carbon impacts get major revision

The climate may be up to 50 percent more sensitive to atmospheric carbon dioxide in the long term than previously thought and climate projections over the next hundreds of years will likely need to be adjusted to reflect this higher sensitivity, according to a new study in Nature Geoscience. The research team, led by the […]

Ocean acidification speeding up

University of Chicago scientists have established that as well as ocean acidification increasing much more rapidly than previously thought, there is also a strong correlation with rising levels of atmospheric carbon dioxide. “Of the variables the study examined that are linked to changes in ocean acidity, only atmospheric carbon dioxide exhibited a corresponding steady change,” […]
