April Flowers for redOrbit.com - Your Universe Online Surges in cultural innovation in early modern human populations were sparked by rapid climate changes between 80,000 and 40,000 years ago – during what was the Middle Stone Age. A new study conducted by a team of scientists from Cardiff University's School of Earth and Ocean Sciences, the Natural History Museum in London and the University of Barcelona examined a marine sediment core off the coast of South Africa to reconstruct...

Detailed analysis shows that only 0.5% (65 of the 12,000 abstracts rated) suggest that humans are responsible for more than 50% of the global warming up to 2001, contrary to the alleged 97% consensus amongst scientists in the Cook et al study. Citing fear mongering and faulty methodology Friends of Science reject the study and President Obama’s tweet as careless incitement of a misinformed and frightened public, when in fact the sun is the main driver of climate change; not human...

Brett Smith for redOrbit.com - Your Universe Online Based on current trends, the Earth is expected to warm considerably over the coming centuries. However, a new study in Nature Geoscience suggests that the more acute predictions of climate change may be overstated. In the study, the international team of researchers looked to see how doubling the concentrations of carbon dioxide in the atmosphere and the Earth's subsequent response would impact climate over several thousand years, a...

redOrbit Staff & Wire Reports - Your Universe Online Increasing temperatures could cause heat-related deaths in Manhattan to increase by one-fifth by the end of the decade, and nearly double before the end of the century, according to new research published in this week’s edition of the journal Nature Climate Change. In the study, scientists from the Columbia University's Earth Institute and the Mailman School of Public Health report that deaths related to global warming could...

[ Watch the Video: What is Global Warming ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Hawaii at Manoa and Woods Hole Oceanographic Institution are looking to events of the past to better understand how rainfall patterns across the Indo-Pacific warm pool – the massive pool of warm water stretching along the equator from Africa to the western Pacific Ocean – will change due to global warming. As part of their study, Pedro DiNezio of...

Dartmouth study contradicts predictions of widespread extinction A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet. The findings, which appear in the journal Global Change Biology, offer new hope for survival of a creature thought to be doomed. Most predictions that tropical cold-blooded animals,...

redOrbit staff & Wire Reports – Your Universe Online An analysis of thousands of peer-reviewed studies published over more than two decades reveals a growing consensus that climate change is caused by human activity. The survey, published Thursday in the journal Environmental Research Letters, contradicts the idea that scientists are deeply divided on the topic, the authors said. "An accurate perception of the degree of scientific consensus is an essential element to public...

People with negative feelings toward climate change seek out more information, study finds Sixty-two percent of Americans now say they believe that global warming is happening, but 46 percent say they are “very sure” or “extremely sure” that it is not. Only 49 percent know why it is occurring, and about as many say they’re not worried about it, according to the April report of the Yale Project on Climate Change Communication. Because information about climate change is...

Picarro Analyzer Took Historic Measurement on Mauna Loa SANTA CLARA, Calif., May 16, 2013 /PRNewswire/ -- Researchers from SCRIPPS studying atmospheric levels at the Mauna Loa Observatory last week recorded the milestone 400 parts per million (ppm) CO(2) concentration using instrumentation from Picarro Inc. The Mauna Loa observatory is a premier atmospheric research facility, and ideal for monitoring climate change due to the undisturbed air and minimal outside influences atop the...

Brett Smith for redOrbit.com - Your Universe Online According to new research in the Proceedings of the National Academy of Sciences (PNAS), average temperatures in central China are 10 to 14 degrees Fahrenheit hotter today than they were during the last Ice Age 20,000 years ago. The authors of the study predict that these findings, which are two to four times greater than previous models have shown, could help researchers build up more precise models of previous climate change patterns...
