Urgent rethink required on Earth’s carbon-sinks, suggests study

In a new study that expands our understanding of how humans contribute to global warming, scientists have discovered that human activity has changed the terrestrial biosphere to make it a significant contributor to climate change. Published in Nature, the study looked at the net balance of the three major greenhouse gases – carbon dioxide, methane, and […]

Rising CO2 causing nutritional content of crops to fall




Field tests by University of California – Davis scientists have shown conclusively that rising levels of carbon dioxide inhibit plants’ ability to assimilate nitrates into proteins. The findings, published in the journal Nature Climate Change, indicate that the nutritional quality of food crops such as wheat, barley, rice, and potatoes is at risk as climate […]

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 […]

Volcanoes keeping a lid on global warming




Climatologists in the U.S. say that dozens of active volcanoes spewing sulfur dioxide into the stratosphere have been offsetting about a quarter of the greenhouse warming on Earth over the last decade. Study leader Ryan Neely, from the University of Colorado Boulder, explained that sulfur dioxide emissions from Earth’s surface eventually rise 12 – 20 […]

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 […]

Climatologists ponder Earth’s missing heat




Astonishingly, climatologists can’t account for roughly half of the heat that is believed to have built up on the Earth in recent years. “The heat will come back to haunt us sooner or later,” lament National Center for Atmospheric Research (NCAR) scientists in an article in the journal Science. The scientists believe that satellite sensors, […]

Meat and dairy consumption link to global warming questioned




Public awareness campaigns such as “Meatless Mondays” and Europe’s “Less Meat = Less Heat” are scientifically inaccurate, says a researcher who contends there is no evidence for repeated claims that diets rich in animal products lead to an increased production of greenhouse gases. Air quality expert Frank Mitloehner, from the University of California-Davis, presented his […]

Insects The Likely Winners From Warming Climate




Fifty-five million years ago, the Earth experienced a rapid jump in global carbon dioxide levels that raised temperatures across the planet. Now, researchers studying fossilized plants from that time have found that the rising temperatures may have boosted the foraging of insects. The findings, published in the Proceedings of the National Academy of Sciences, could […]
