A conceptual model is constructed based upon the Bjerknes hypothesis of tropical atmosphere–ocean interaction. It is shown that strong feedbacks among the trade winds, equatorial zonal sea surface temperature contrast, and upper-ocean heat content occur in the tropical Pacific basin. Coupled atmosphere–ocean dynamics produce both the strong Pacific cold-tongue climate state and the El Niño–Sout...

Responses to environmental variability sheds light on how individuals are able to survive in a particular habitat and provides an indication of the scope and limits of its niche. To understand whether climate has a direct impact on activity, and determine whether vervet monkeys have the behavioral flexibility to respond to environmental change, we examined whether the amount of time spent resti...

Evidence from the Irish Sea basin supports the existence of an abrupt rise in sea level (meltwater pulse) at 19,000 years before the present (B.P.). Climate records indicate a large reduction in the strength of North Atlantic Deep Water formation and attendant cooling of the North Atlantic at this time, indicating a source of the meltwater pulse from one or more Northern Hemisphere ice sheets. ...

Primary pneumonic plague lias been known to occur in cold climates such as that of Eastern Siberia and Manchuria, but fortunately it is known to occur comparatively rarely in India. In India cases are reported to have occurred mostly in northern parts of India, especially at the base of the Himalayas, but occasionally cases have been reported from other parts as well. It is known that in these ...

Eight of the current sizing and design methods proposed for bioretention facilities were evaluated for rainfall runoff and snow storage volumes for a costal cold climate in Trondheim, Norway. The RECARGA bioretention infiltration model was used to compare the performance of the methods using 30 months of observed data from a pilot scale bioretention box. The surface areas, total ponding time, n...

UNLABELLED • PREMISE OF THE STUDY Cold tolerance is a critically important factor determining how plants will be influenced by climate change, including changes in snowcover and extreme weather events. Although a great deal is known about cold tolerance in Arabidopsis thaliana, it is not highly cold tolerant. This study examined cold tolerance and its genetic diversity in an herbaceous subarc...

The stated aims of the coalition government’s White Paper, Equity and Excellence: Liberating the NHS (Department of Health 2010a) are putting patients and the public first and improving health care outcomes. While there are elements of continuity with policies that have been implemented over the past 20 years, the scope of the government’s proposals, the speed with which they have been develope...

Summit metabolic rate (M(sum), maximum cold-induced metabolic rate) is positively correlated with cold tolerance in birds, suggesting that high M(sum) is important for residency in cold climates. However, the phylogenetic distribution of high M(sum) among birds and the impact of its evolution on current distributions are not well understood. Two potential adaptive hypotheses might explain the p...

BACKGROUND AND AIMS Recent global changes, particularly warming and drought, have had worldwide repercussions on the timing of flowering events for many plant species. Phenological shifts have also been reported in alpine environments, where short growing seasons and low temperatures make reproduction particularly challenging, requiring fine-tuning to environmental cues. However, it remains unc...

BACKGROUND This study describes heat- and cold-related mortality in 12 urban populations in low- and middle-income countries, thereby extending knowledge of how diverse populations, in non-OECD countries, respond to temperature extremes. METHODS The cities were: Delhi, Monterrey, Mexico City, Chiang Mai, Bangkok, Salvador, São Paulo, Santiago, Cape Town, Ljubljana, Bucharest and Sofia. For ea...
