Proxy indicators of relative moisture balance, in combination with long control simulations from coupled climate models, show that the Indian Ocean drives multidecadal hydroclimate variability by altering the local Walker circulation, whereas the influence of the Pacific Ocean is minimal on these timescales.

Sea-dwelling fossil shells reveal 60,000-year-old link relating to climate change

Link dating back to 60,000 years between sea surface temperature of Northeast Indian Ocean (NEIO) and North Atlantic climate oscillations, probably through ocean atmospheric connection, was found by researchers. In a study on oxygen isotopes deposited in fossil shells in the ocean sediment through AMS radiocarbon dating, it was also found that the Indian monsoon was much more intense 6,000-8,000 years ago than the present period. In the study carried out by scientists from CSIR-National Geophysical Research Institute here, researchers from the School of Geography Science, Nanjing Normal University and the School of Earth Science and Engineering, Nanjing University, Nanjing, China collaborated in dating the fossils.

Terming the current global climate change scenario as "serious times", a US environmental law expert on Wednesday cautioned that the rise in sea level in the Indian Ocean could make cities like Kol

Black carbon is a component of soot, released during combustion, particularly incomplete combustion of fossil fuels or biomass. It is released when carbon is only partially combusted. The main sources of black carbon emissions are burning of biomass in inefficient cooking stoves, diesel emissions from the transport sector and from

The problem of piracy in the Indian ocean is hampering the collection of accurate water surface temperatures by international weather forecasting agencies that indirectly affects India’s long-range

Global mean sea surface temperature (SST) has risen steadily over the past century, but the overall pattern contains extensive and often uncertain spatial variations, with potentially important effects on regional precipitation. Observations suggest a slowdown of the zonal atmospheric overturning circulation above the tropical Pacific Ocean (the Walker circulation) over the twentieth century. Although this change has been attributed to a muted hydrological cycle forced by global warming, the effect of SST warming patterns has not been explored and quantified.

It has been widely believed that the tropical Pacific trade winds weakened in the last century and would further decrease under a warmer climate in the 21st century. Recent high-quality observations, however, suggest that the tropical Pacific winds have actually strengthened in the past two decades. Precise causes of the recent Pacific climate shift are uncertain.

Madagascar, the island nation in the Indian Ocean is home to some of the exotic and rate flora and fauna. However, there is bad news for its palms.

Food security problems caused by climate change and ocean acidification will hit small island and coastal nations hardest, environmental group Oceana said on Monday.

Tropical cyclones over the Arabian Sea in the pre-monsoon season (May–June) have intensified since 1997 owing to significant reductions in storm-ambient vertical wind shear (VWS) in the troposphere; these reductions have decreased on average by about 3 m s−1 from the pre-1997 epoch (1979–1997) to the recent epoch (1998–2010)1. The authors attribute the reduction of pre-monsoon VWS to the dimming effects of increased anthropogenic black carbon and sulphate emissions.
