Scientists More Certain Than Ever on Climate Change, Report Says

NBC: Experts are more certain than ever that human activity is changing the global climate, even though they don't fully understand every detail of the climate system, according to a new report released Wednesday by two of the world's leading scientific bodies. The document from the U.S. National Academy of Sciences and the United Kingdom's Royal Society aims to move the climate change debate beyond humans' role in global warming to a discussion of how to limit the impacts on society. "Climate change...

Scientists blend synthetic air to measure climate change
2014-02-26 19:31:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Scientists at the National Physical Laboratory (NPL) have produced a synthetic air reference standard which can be used to accurately measure levels of carbon dioxide and methane in the atmosphere. This will greatly help scientists contribute to our understanding of climate change. A paper published in Analytical Chemistry describes how researchers at NPL have created a synthetic gas standard for the first time, which is comparable to the World Meteorological Organisation (WMO) scale and can be...

Heat extremes increase despite global warming hiatus: scientists
2014-02-26 09:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Hot weather extremes have increased around the world in the past 15 years despite a slowdown in the overall pace of global warming, a study showed on Wednesday. Heat extremes are among the damaging impacts of climate change as they can raise death rates, especially among the elderly, damage food crops and strain everything from water to energy supplies. "Observational data show a continued increase of hot extremes over land during the so-called global warming hiatus," scientists in Switzerland,...

Volcanic Eruptions Help Slow Down Global Warming - Scientists
2014-02-24 09:04:00| Climate Ark Climate Change & Global Warming Newsfeed
International Business Times: While scientists claimed temperatures have risen since the start of the century, they were far below compared to the rise in man-made greenhouse gases. Earlier, scientists surmised the particles released to the air during volcanic eruptions would trigger temperatures worldwide to further escalate from 1998. But they noted the reverse occured. "This is a complex detective story," Benjamin Santer, lead author of the study, "Volcanic Contribution to Decadal Changes in Tropospheric Temperature"...

Volcanic eruptions contributed to global warming pause, scientists claim
2014-02-23 20:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: The impact of volcanic eruptions on global warming could provide a new explanation for the so-called pause used by sceptics to deny climate change is happening, scientists have said. According to a study in the US, models for predicting the rate at which temperatures around the world would rise from 1998 onwards did not take into consideration the measurable impact volcanoes can have. Rather than contributing to global warming, eruptions release particles into the air that reflect sunlight...
