Origins of ancient Chinese civilization under reconsiderationAugust 21st, 2009 WASHINGTON - Recent archaeological discoveries from far-flung corners of China are forcing scientists to reconsider the origins of ancient Chinese civilization. A group of articles by Science news writer Andrew Lawler have explored how, over several millennia, China evolved from a much wider array of peoples and cultures than once imagined.
Scientists can account for only half of global warmingJuly 15th, 2009 WASHINGTON - Current climate change models prepared by scientists can explain only half the warming that took place on earth in the ancient past, says a new study. The study contains an analysis of published records from a period of rapid climatic warming about 55 million years ago known as the Palaeocene-Eocene thermal maximum (PETM).
Scientists' best predictions about global warming might be incorrectJuly 15th, 2009 WASHINGTON - A new study has suggested that scientists' best predictions about global warming might be incorrect. The study found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past.
Maize agriculture may have fueled ancient Andean civilizationJuly 9th, 2009 WASHINGTON - In a new study, a skeleton found at a roughly 1,000-year-old site in Peru's Andes mountains has yielded chemical evidence of substantial maize consumption, which suggests that the farming of the crop led to the rise of the ancient Andean civilization. Prehistoric communities in one part of Peru's Andes Mountains may have gone from maize to amazingly complex.

Global warming may increase dispersal of flora in Northern forestsJune 12th, 2009 WASHINGTON - A new research has indicated that an increase in temperature of only a couple of degrees may increase the dispersal of plants in Northern forests and the spread of plant species into forest clearings after felling or forest fires. The research, in the impact of global warming on seed and pollen dispersal, was led by University of Helsinki researcher Anna Kuparinen.
Abrupt global warming can cause a shift in monsoon patternsJune 12th, 2009 WASHINGTON - A new study has determined that an abrupt change in climate, like global warming, can cause a shift in monsoon patterns and hurt agriculture. The study took into account the fact that an abrupt change in climate in the distant past has been associated with a shift of seasonal monsoons to the south, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
Indus Valley script encodes spoken language, says studyApril 30th, 2009 WASHINGTON - The Rosetta Stone, an ancient Egyptian artefact, has allowed 19th century scholars to translate symbols left by an ancient civilization thus enabling them to decipher the meaning of Egyptian hieroglyphics. But the symbols found on many other ancient artefacts remain a mystery, including those of a people that inhabited the Indus valley between Pakistan and India.
Wetlands likely source of methane from warming event 11,600 years agoApril 24th, 2009 WASHINGTON - A new research by an international team of scientists has determined that an expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago. The international research team was led by Scripps Institution of Oceanography at UC (University of California) San Diego.

Antarctica warming, study saysJanuary 22nd, 2009 WASHINGTON - Antarctica is warming, despite the recent scientific consensus that the southernmost continent was not being impacted by global warming, a study published in the journal Nature said Thursday. Scientists had observed warming in the Antarctic Peninsula that extends north from the icy continent, but the rest of the continent was believed to be stable or even cooling as the rest of the Earth's continents saw temperatures increase.
