Scientists who published the famous “hockey stick” graph experienced sustained attacks soon after the figure was incorporated in the 2001 report from the Intergovernmental Panel on Climate Change. Now one of those scientists, Ray Bradley, has written a very personal account of his experience. He spoke to Owen Gaffney about his new book.

Learning from the past

When it comes to managing the environment, we rarely look beyond the past few years to inform decisions. John Dearing says this needs to change.

July 26, 2011 Tracking groundwater depletion As water demand rises rapidly, some regions are withdrawing groundwater faster than it can recharge. Now scientists can couple new space-based observations with models and data to quantify global and regional groundwater changes, reports Ninad Bondre.
July 26, 2011 In the line of fire Scientists who published the famous “hockey stick” graph experienced sustained attacks soon after the figure was incorporated in the 2001 report from the Intergovernmental Panel on Climate Change. Now one of those scientists, Ray Bradley, has written a very personal account of his experience. He spoke to Owen Gaffney about his new book.

July 26, 2011 The Global Fix on Nitrogen The International Nitrogen Initiative brings together a range of stakeholders including scientists, industry and policymakers. Naomi Lubick discusses its foundations with James Galloway.
July 26, 2011 Did rain bring down the Roman Empire? Analysis of the most complete tree-ring database for Central Europe provides a record of climate change over the past 2500 years. It also reveals synchronies with important historical events, reports Naomi Lubick.
January 1, 2011 Mountain glaciers face the heat The recognition of an error in the fourth assessment report of the Intergovernmental Panel on Climate Change put the spotlight on glaciers. Not all glaciers are about to disappear but their recession is real and so are the impacts the loss of this “stored water” will have on ecosystems and societies, Ray Bradley asserts.
January 1, 2011 Climate geoengineering. Could we? Should we? Radical technological responses to counteract global warming are receiving increased attention as a possible policy option. But is geoengineering a potential safety net, a distraction or a dead end? Phil Williamson explores.
January 1, 2011 Phosphorus: How much is enough? Phosphorus, crucial to agriculture and life, is at present derived from non-renewable sources. Demand will eventually outstrip supply, but when this will happen is a matter of debate. Ninad Bondre takes stock.
January 1, 2011 The perfect storm Soil moisture patterns seem to be the trigger for new storms in the dusty Sahel. Chris Taylor recounts his experience of one such storm and discusses how the Sahel soil influences weather patterns.
January 1, 2011 Climate change’s famous cousin Ocean acidification has transitioned from a little-known phenomenon to a buzzword within a span of five years. The concomitant explosion of research on this topic has provided many general insights into its effects. But as Sarah Cooley reminds us, many of the specifics regarding its consequences for humans and ecosystems await elaboration.
