    Climate change accelerates growth of urban trees in metropolies worldwide Abstract: Despite the importance of urban trees, their growth reaction to climate change and to the urban heat island effect has not yet been investigated with an international scope. While we are well informed about forest growth under recent conditions, it is unclear if this […]

  • Paleo-Climatology May Have Produced Wrong Results

    • Date: 17/11/17
    • Georgia Institute of Technology

    For researchers pursuing the primordial history of oxygen in Earth’s atmosphere, a new study might sour some “Eureka!” moments. A contemporary tool used to trace oxygen by examining ancient rock strata can produce false positives, according to the study, and the wayward results can mask as exhilarating discoveries. Common molecules called ligands can bias the results of a […]

  • Scientists Accused Of Scaremongering, ‘Overheated Claims’ With Warning To Humanity

    • Date: 17/11/17
    • CBC News

    A recent warning to humanity endorsed by thousands of scientists around the world includes “scaremongering” and “overheated” claims while ignoring much of the progress made in recent decades, some experts say. “It concerns me that the message from science is this doom-and-gloom scenario that just turns off about 75 per cent of people,” said Erle Ellis, an associate professor of geography and environmental systems at the […]

  • Baltic clams and worms release as much greenhouse gas as 20,000 dairy cows

    • Date: 14/11/17
    • Cardiff University

    Scientists have shown that ocean clams and worms are releasing a significant amount of potentially harmful greenhouse gas into the atmosphere. The team, from Cardiff University and Stockholm University, have shown that the ocean critters are producing large amounts of the strongest greenhouse gases – methane and nitrous oxides – from the bacteria in their guts. Methane gas is making its […]

  • New Study: Most Economics Research Papers Are Wrong

    • Date: 10/11/17
    • John P. A. Ioannidis, T. D. Stanley, Hristos Doucouliagos, The Economic Journal

    Nearly 80% of the reported effects in these empirical economics literatures are exaggerated; typically, by a factor of two and with one-third inflated by a factor of four or more. Abstract We investigate two critical dimensions of the credibility of empirical economics research: statistical power and bias. We survey 159 empirical economics literatures that draw […]

  • NASA: Volcanic Activity Is Heating Up Antarctica’s Ice Sheet

    • Date: 08/11/17
    • Daily Caller, NASA

    Ancient underground streams of heated rock, called a mantle plume, might be an explanation for the instability of Antarctica’s western ice sheet, according to a new NASA study. Scientists have been debating whether or not mantle plume heat contributes to western Antarctica’s instability. Some recent studies provided evidence this might be the case, but even […]

  • FOI: Internal NOAA Emails Reveal Ocean Acidification Not A Current Problem

    • Date: 07/11/17
    • Steve Milloy, Junkscience.com

    ‘I think it is really important to resist the New York Times editor’s impulse to say that ocean acidification is wreaking all sorts of havoc right now, because for ecological systems, we don’t have the evidence to say that.’ JunkScience.com got NOAA scientist e-mails via FOIA? Why can’t Congress?     Last October, the New York […]

  • Scottish Summertime Temperatures Not Significantly Warmer Than During Medieval Warm Periods, Scientists Find

    • Date: 06/11/17
    • Miloš Rydval et al., Climate Dynamics, November 2017, Volume 49, Issue 9–10, pp 2951–2974

    Within the context of reconstruction uncertainty, recent summertime warming in Scotland is not significantly more pronounced than past reconstructed warm periods (e.g. around 1300 and 1500). Abstract – This study presents a summer temperature reconstruction using Scots pine tree-ring chronologies for Scotland allowing the placement of current regional temperature changes in a longer-term context. ‘Living-tree’ chronologies […]
