Ocean warming slows coral growth in the Central Red Sea
Sea surface temperature (SST) across much of the tropics has increased by 0.4

Recent observational surveys have shown significant oceanic bottom-water warming. However, the mechanisms causing such warming remain poorly understood, and their time scales are uncertain. Here, we report computer simulations that reveal a fast teleconnection between changes in the surface air-sea heat flux off the Ad
Recent studies have linked climatic and social instabilities in ancient China; the underlying causal mechanisms have, however, often not been quantitatively assessed.
<p>There is uncertainty about the response of the climate system to future trajectories of radiative forcing. To quantify this uncertainty we conducted face-to-face interviews with 14 leading climate scientists, using formal methods of expert elicitation. We structured the interviews around three scenarios of radiative forcing stabilizing at different levels.
Global patterns of biodiversity and comparisons between tropical and temperate ecosystems have pervaded ecology from its inception. However, the urgency in understanding these global patterns has been accentuated by the threat of rapid climate change.
Tuticorin: Global warming had become a serious threat and a series of programmes were being conducted with the participation of delegates from developed countries to deliberate on reducing the impact of climate change, said B. Sugirtharaj, District Forest Officer.
Mapping variations in regional sea level changes of different parts of the Indian Ocean could help developing countries better adapt to the effects of climate change, according to a study.
The alarming and unprecedented rise in the atmospheric concentration of greenhouse gases under global climate change warrants an urgent need to understand the synergistic and holistic mechanisms associated with plant growth and productivity. Photosynthesis is a major process of sequestration and turnover of the total carbon on the planet.
In 2009, the world celebrated the 200th anniversary of the life and work of Charles Darwin, a transformational scientist who brought about a revolution in our understanding of evolution.
Population decline and a shift in the geographical distribution of some ectothermic animals have been attributed to climatic warming. Here, we show that rises in water temperature of a few degrees, while within the thermal window for locomotor performance, may be detrimental to diving behaviour in air-breathing ectotherms (turtles, crocodilians, marine iguanas, amphibians, snakes and lizards).
<p>The deuterium excess of polar ice cores documents past changes in evaporation conditions and moisture origin. New data obtained from the European Project for Ice Coring in Antarctica Dome C East Antarctic ice core provide new insights on the sequence of events involved in Termination II, the transition between the penultimate glacial and interglacial periods.
Many climate researchers worry that scepticism about global warming is on the rise. Jeff Tollefson investigates the basis for that concern and what scientists are doing about it.
It isn't enough to explain the facts of climate change very, very clearly. Building public trust requires researchers to change their practices. (Editorial)
Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties
Sea turtles are vulnerable to aspects of climate change because they have life history, physiological attributes and behaviour that make them extremely sensitive to environmental changes.
To examine changes in the wintertime seasonal (December, January and February) temperature and precipitation over the Siachen Glacier, one of the largest glaciers outside the polar region, an analysis of its temperature and precipitation indices is planned.
<p>CHENNAI: “Global warming is a global problem. Global problems need global solutions,” said Hans Burkhard Sauerteig, Consul General of the Federal Republic of Germany, here on Tuesday.<br />
In a recent paper, we documented strong historical linkages between temperature and civil conflict in Africa. Sutton et al. raise two concerns with our findings: that the relationship between temperature and war is based on common trends and is therefore spurious, and that our model appears overly sensitive to small specification changes.
The potential relationship between climate change and conflict is intriguing and warrants rigorous study. However, the proposition by Burke et al. that warming may be a directly causative factor in the risk of civil war in Sub-Saharan Africa seems unlikely. The analysis of Burke et al. (1) suggests instead a tenuous historical association between warming and increased conflict. (Letters)
