The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
India has made its first ever claim before the International Seabed Authority (ISA) for the exploration of poly-metallic sulphide from the Mauritius seas. Prior to country's first ever seabed exploration for sulphides, a preliminary study has been completed with the help of the National Centre for Antarctic and Ocean Research …
Monsoon and cyclones : Role of climate change - A presentation by M.R.Ramesh Kumar at the 4th National Research Conference on Climate Change, Indian Institute of Technology, Madras, October 26-27, 2013.
Tropical Indian Ocean SST variability in different CMIP5 scenarios - A presentation by Shamal Date, Karumuri Ashok, P. Swapna, Terray Pascal and J. V. Revadekar at the 4th National Research Conference on Climate Change, Indian Institute of Technology, Madras, October 26-27, 2013.
"Climate Change 2013: The Physical Science Basis" is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of the physical aspects of climate change puts a focus on those elements that are relevant to understand past, document current, …
In the present study, the observed variability of monsoon droughts over India has been examined using a drought monitoring index, namely the Standardized Precipitation Evapo-transpiration Index (SPEI). For calculating the SPEI over different time periods, long term (1901–2010), high resolution, monthly gridded temperature and rainfall data sets have been used. …
Projection of Indian summer monsoon for the 21st century using RegCM4.3 with GFDL forcing - A presentation by K. C. Pattnayak, S. K. Mishra and S. K. Dash at the 4th National Research Conference on Climate Change, Indian Institute of Technology, Madras, October 26-27, 2013.
In the wake of the newest pollution map of the Indian Ocean, showing an ugly halo of pollution around Sri Lanka, the Marine Environment Protection Authority (MEPA) yesterday stressed that it had not as yet conducted proper studies to assess the marine pollution situation here. EPA’s Manager of Operations Jagath …
his is a title under the Issues in History series which ‘begins with the premise that history is both about writing the past and about the re-examination of the sources as stated by series editors. The book contains articles by different authors grouped together under four distinct parts which are, …
Scientists have sounded the alarm over the mounting threat to marine turtle populations worldwide from climate change and coastal development. The scientists have made a strong pitch for protecting key nesting grounds, and areas that may be suitable for the purpose in the future, to ensure that the marine reptiles …
Climate change causes global mean sea level to rise due to thermal expansion of seawater and loss of land ice from mountain glaciers, ice caps and ice sheets. Locally, sea level can strongly deviate from the global mean rise due to changes in wind and ocean currents. In addition, gravitational …
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 …
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 Kolkata and Mumbai vulnerable. "There might be particular problems due to the sea level rise in the Indian …
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 forecasts, a top weather scientist has said. India depends upon global agencies for the prediction of El Nino and the Indian Ocean Diapole …
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 …
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 …
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. Nearly 83 per cent of the nation’s palms are threatened with extinction, says the latest update of the IUCN (International Union of …
