All five of Switzerland's commercially operational nuclear power reactors are to be retrofitted to increase hydrogen control capabilities, according to new requirements set by the country's nuclear regulator ENSI.

Deal close for Indian reactor imports

World Nuclear News - Mon, 01/26/2015 - 10:02
India and America are close to a deal that would resolve liability issues and enable the long-awaited import of US-built reactors. Other nations, too, stand to benefit from India's plan to import up to 26 large nuclear reactors.

The Sahara was more humid and habitable thousands of years ago. Reconstructions of North African hydroclimate show that the onset of aridity started in the north, with the monsoon rains weakening progressively later at lower latitudes.

Carbonate weathering as a driver of CO2 supersaturation in lakes

Most lakes and reservoirs have surface CO2 concentrations that are supersaturated relative to the atmosphere. The resulting CO2 emissions from lakes represent a substantial contribution to the continental carbon balance. Thus, the drivers of CO2 supersaturation in lakes need to be understood to constrain the sensitivity of the land carbon cycle to external perturbations. Carbon dioxide supersaturation has generally been attributed to the accumulation of inorganic carbon in lakes where respiration exceeds photosynthesis, but this interpretation has faced challenges. Here we report analyses of water chemistry data from a survey of Spanish reservoirs that represent a range of lithologies, using simple metabolic models. We find that, above an alkalinity threshold of 1 mequiv. l−1, CO2 supersaturation in lakes is directly related to carbonate weathering in the watershed. We then evaluate the global distribution of alkalinity in lakes and find that 57% of the surface area occupied by lakes and reservoirs—particularly in tropical and temperate latitudes—has alkalinity exceeding 1 mequiv. l−1. We conclude that lake inputs of dissolved inorganic carbon from carbonate weathering should be considered for the CO2 supersaturation of lakes at both regional and global scales.

Long-term winter warming trend in the Siberian Arctic during the mid- to late Holocene

Relative to the past 2,000 years, the Arctic region has warmed significantly over the past few decades. However, the evolution of Arctic temperatures during the rest of the Holocene is less clear. Proxy reconstructions, suggest a long-term cooling trend throughout the mid- to late Holocene, whereas climate model simulations show only minor changes or even warming. Here we present a record of the oxygen isotope composition of permafrost ice wedges from the Lena River Delta in the Siberian Arctic. The isotope values, which reflect winter season temperatures, became progressively more enriched over the past 7,000 years, reaching unprecedented levels in the past five decades. This warming trend during the mid- to late Holocene is in opposition to the cooling seen in other proxy records. However, most of these existing proxy records are biased towards summer temperatures. We argue that the opposing trends are related to the seasonally different orbital forcing over this interval. Furthermore, our reconstructed trend as well as the recent maximum are consistent with the greenhouse gas forcing and climate model simulations, thus reconciling differing estimates of Arctic and northern high-latitude temperature evolution during the Holocene.

WASHINGTON (AP) — In a story Jan. 16, The Associated Press reported that the odds that nine of the 10 hottest years have occurred since 2000 are about 650 million to one. These calculations, as the story noted, treated as equal the possibility of any given year in the records being one of the hottest. [...]
