World’s Oldest Unused Stone Tools Found (So They Say) 

State of the Planet [2015-05-26 17:28:46]  recommend  recommend this post  (17 visits) info

Last week, it was announced that scientists had found the world's oldest stone tools, in Kenya, dated at 3.3 million years. The precise dating of the tools was made possible by Chris Lepre and Dennis Kent of Lamont-Doherty Earth Observatory, who used periodic reversals in earth's magnetic field to nail the timing. Now, in a related study, a separate team says they have discovered the world's oldest stone tools that were never used--an apparent revelation about early human leisure

In this edition of GeoEd, Sam Illingworth, a lecturer in science communication at Manchester Metropolitan University, explores the benefits of a more informal teching style and how the incorporation of play into everyday teaching can help to engage and enthuse students who oterhwise struggle to connect with the sciences. Despite the hard work, there are some real perks to being a scientists: field work, conferences, travelling, collaborations, etc… to name but a few. The key is to show [...]

Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

Since the late 1990s, global warming has stabilized, even as greenhouse gases have risen. That defies simple models that say the temperature should keep going up. Many scientists think the so-called “hiatus” is taking place in part because much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for

Guest posting from Bill Ruddiman, University of Virginia Recently I’ve read claims that some scientists are opposed to AGW but won’t speak out because they fear censure from a nearly monolithic community intent on imposing a mainstream view.
