Posted by Olive Heffernan on behalf of Alex Witze June 1 is almost here, and for residents of the eastern US, Caribbean and Central America that means just one thing: stock up on the plywood and batten down the hatches, for the Atlantic hurricane season is upon us. This week’s Nature features a minor rush of hurricane-related items. First off, in a technical manuscript, Ryan Sriver and Matthew Huber of Purdue University spell out how tropical cyclones could play a significant role in mixing the ocean’s topmost layers. They find that about 15 percent of the peak ocean heat transport … Read more
As devotees of Nature‘s print edition know, one of its treasures is the Research HIghlights spread at the beginning of every issue, put together with great care and flair by my colleague Jenny Hogan. Most of the spread consists of little comptes rendus of papers elsewhere about which we find ourselves enthused about, but there’s also a little micro-column at the end called Journal Club. In this column Jenny invites a scientist of note to recommend a paper from the recent literature and explain why she or he is enthused about it.
A while back it struck us that these journal club pieces would be enhanced if they were easily discussable — discussion being the point of a journal club, really. So we deicided to load them up on a blog, one entry per post, and let them find their interactive audience. Voila.
Posted by Olive Heffernan Solutions to climate change could come in extremely small sizes, according to a report released last week by the UK Department for Environment Food and Rural Affairs (DEFRA). “Environmentally Beneficial Nanotechnologies: Barriers and Opportunities” explores the application of nanoscience in five key areas that could reduce greenhouse gas emissions, namely: insulation, photovoltaics, electricity storage, engine efficiency and the hydrogen economy. Nanotechnology is a hugely exciting, if relatively young, branch of science with seemingly limitless possibilities. What scientists are discovering is that everyday materials, at very small sizes of one or several nanometers (a nanometer is equivalent … Read more
Posted by Olive Heffernan on behalf of Kevin Vranes Far off the American radar screen, and perhaps not a bright blip on the European one either, is the perverse incentive problem for carbon emissions offsets. As voluntary offset purchases by both individuals and corporations ramp up, a strong backlash against “offsetting your guilt” is building astride. But offsetting guilt as a personal choice or for corporate strategy on an individual basis is one thing. Using an international financial trading mechanism embedded in an international treaty is quite another. And when the mechanisms of one international environmental treaty leads to the … Read more
Posted by Olive Heffernan on behalf of Michael Hopkin It looks as if the Southern Ocean – the great white hope for sucking up mankind’s carbon emissions – is slowly losing its efficiency as a carbon sink due to largely unforseen climate feedbacks. It’s early days, but this first real-world measurement of a slowdown in the ocean’s ability to dissolve carbon could have worrying implications for those currently thinking about how to stabilize atmospheric greenhouse levels.
