Recent climate change is affecting the earth system to an unprecedented extent and intensity and has the potential to cause severe ecological and socioeconomic consequences. To understand natural and anthropogenic induced processes, feedbacks, trends, and dynamics in the climate system, it is also essential to consider longer timescales. In this context, annually resolved tree-ring data are oft...
australian rainfall is related with numerous key climate predictors namely el-nino southern oscillation (enso), indian ocean dipole (iod) and southern annular mode (sam). some studies have tried to discover the effects of these climate predictors on rainfall variability of different parts of australia, particularly western australia, queensland and victoria. nonetheless, clear association betwe...
BACKGROUND The health impacts of climate change are an issue of growing concern in the Pacific region. Prior to 2010, no formal, structured, evidence-based approach had been used to identify the most significant health risks posed by climate change in Pacific island countries. During 2010 and 2011, the World Health Organization supported the Federated States of Micronesia (FSM) in performing a ...
Climate change poses a grave threat to sustainability. The first section of Sustainability2009: The Next Horizon, therefore, is devoted to Climate Change and Adaptation. Contributions focus on the historical consequences of climate change for human societies, as well as the effects of current climate change on sea level, lightning intensity, fire, the El Niño– Southern Oscillation (ENSO), and h...
Climate variability and change significantly influences the health, prosperity, and well-being of individuals, societies, and the environment. For the United States this has been demonstrated, most recently, by several high impact events such as the 1997–98 El Niño event, the hurricane seasons of 2004 and 2005, the ongoing drought since 1999 in the Southwest, falling Great Lake levels, and the ...
Climate change has the potential to affect the ecology and evolution of every species on Earth. Although the ecological consequences of climate change are increasingly well documented, the effects of climate on the key evolutionary process driving adaptation-natural selection-are largely unknown. We report that aspects of precipitation and potential evapotranspiration, along with the North Atla...
The climate over South America displays certain characteristics of monsoon systems which respond to seasonal development of land–ocean thermal contrast. The South American climate exhibits seasonal changes in precipitation, reversal of anomalous low-level winds and upper level anticyclone (Zhou and Lau 1998; Nogués-Paegle et al. 2002; Vera et al. 2006; Marengo et al. 2012). The austral seasonal...
[1] We present a tree-ring based reconstruction of the Atlantic Multidecadal Oscillation (AMO) which demonstrates that strong, low-frequency (60–100 yr) variability in basin-wide (0–70 N) sea surface temperatures (SSTs) has been a consistent feature of North Atlantic climate for the past five centuries. Intervention analysis of reconstructed AMO indicates that 20th century modes were similar to...
[1] Understanding the phase relationship between climate changes in the Arctic and Antarctic regions is essential for our understanding of the dynamics of the Earth’s climate system. In this paper we show that the 20th century de‐ trended Arctic and Antarctic temperatures vary in anti‐phase seesaw pattern – when the Arctic warms the Antarctica cools and visa versa. This is the first time that a...
The main driver for the large research effort devoted to developing and improving seasonal climate prediction models is the fact that El Nino Southern Oscillation (ENSO) events (quasiperiodic fluctuations in Indo-Pacific Ocean sea surface temperatures and mean sea level pressure) represent, on a global scale, the greatest source of interannual climate variability and are, to some extent, predic...
