Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, according to this new report by the World Meteorological Organisation (WMO). This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface …
Asian pollution is a global problem. Millions of tonnes of soot, sulphur dioxide and other pollutants are fast-tracked into the stratosphere each year by the summer monsoon. "The monsoon is one of the most powerful atmospheric circulation systems on the planet, and it happens to form right over a heavily …

The social cost of carbon (SCC), defined as the estimated price of the damages caused by each additional ton of carbon dioxide (CO2) released into the atmosphere, is the volume dial on government regulations affecting greenhouse gases: The higher the SCC is set, the more stringent the regulatory standards. This …
This report presents 24 indicators, each describing trends related to the causes and effects of climate change. The report focuses primarily on the United States, but in some cases global trends are presented to provide context or a basis for comparison. It aims to collect data and generate analyses to: …
Noting that the decade 2000-2009 was warmest ever recorded, the World Meteorological Organisation (WMO) has said that 2009 was the fifth-warmest year since climate records began in 1850. In a report on its 60th anniversary, the UN weather agency said the nineties were warmer than the eighties.The report showed that …
Can we trust the Ocean-Atmosphere coupled models to predict future climate accurately?: a paper presented by Prof. J Srinivasan IISc, Bangalore at National climate research conference, IIT Delhi, March 5-6, 2010.
This document contains the presentation by D. V. Borole, NIO Goa, on dynamics of trace gases at low level planetary boundary layer observed at Cabo de Rama, west coast of India, presented at National climate research conference, IIT Delhi, March 5-6, 2010. Atmospheric gases are considered to modulate the global …
This document contains the presentation by Tarun Gupta, Abhishek Chakraborty on toxic metals influencing continental atmosphere, presented at National climate research conference, IIT Delhi, March 5-6, 2010. Atmospheric aerosols stimulate strong research interest primarily due to their importance in influencing climate over both land and water, and causing deleterious effects …
On 1 April 1960, the world's first weather satellite, the Television Infrared Observation Satellite 1 (TIROS 1), was launched from Cape Canaveral, Florida, into a 99-min orbit at an altitude of about 725 km. The cylindrical (1.1-m diameter, 0.48-m tall), 120-kg spacecraft was spin-stabilized, rotating between 8 and 12 times …
Geo-engineering is based on the princi- ple that making tweaks to the atm- osphere, such as seeding the clouds to make them brighter and more reflective, could bring down global temperatures US RESEARCHERS are studying the steam from ships, condensation trails of airplanes and volcanic erup- tions as they try …
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data …
Trains, planes and cars halted by snow and ice. Gas and electricity supplies rationed. Sensitive crops ruined. Boats frozen into waterways. For weeks, images of the coldest weather for decades have filled the media across Europe, Asia and North America. But there is an alternative weather story. In much of …
Sun, Not Humans, Influencing Climate, Says Scientist Ahmedabad: Janardan Negi, a distinguished theoretical geophysicist, has made a controversial forecast that the global warming phase will change to global cooling and the temperature anomaly will decline substantially by the year 2030. Some effects of the process are already evident in the …
The 2009 southwest monsoon recorded the third highest deficient all India southwest monsoon season rainfall (-22% of LPA) during the period 1901-2009. All the monsoon months except July recorded large deficient rainfall. Region wise, except south Peninsula, all other homogeneous regions recorded much below normal rainfall. Activity of depression was …
Following a unified approach, an objective criterion has been developed for the determination of yearwise onset and withdrawal dates of the summer monsoon over the 19 subregions across India. In total 14 meteorological parameters are considered in the development of the objective criteria, two of which represent heating over south …
The Intergovernmental Panel on Climate Change (IPCC) has published a report of the expert meeting on Detection and Attribution Related to Anthropogenic Climate Change. The meeting, organized jointly by Working Groups I (Physical Science Basis and Impacts) and II (Adaptation and Vulnerability), was held in Geneva, Switzerland, from 14-16 September …
