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 …
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 …
US scientists have discovered fog moving across the south pole of Saturn's largest moon, Titan. Titan looks to be the only place in the solar system aside from Earth to have copious quantities of liquid (largely, liquid methane and ethane) on its surface. The new discovery suggests that Earth and …
This document by IMD, contains the highlights of temperatures during the year 2009. It presents the monthly temperature profile with spatial pattern over India. For full report: http://www.imd.gov.in/doc/warm2009.pdf
HARDEV SANOTRA The world's weatherman tells us that this year had been the fifth warmest since 1850 and the decade has been the hottest on record. The Geneva-based World Meteorological Organisation (WMO) released its annual data earlier at the UN climate conference which shows that the combined sea and land …
In negotiating the new climate change protocol in Copenhagen this month, we must not lose sight of our objective: to reduce the rate of annual global emissions so that we stay below the threshold of 450 parts per million for the concentration of greenhouse gases in the atmosphere. Even that …
How do climatologists know that increasing levels of carbon dioxide in the atmosphere will warm the earth? First, basic science tells them that CO2 molecules trap energy from the solar-heated earth and prevent its radiation back into space. And second, the history of climate over millions of years shows the …
