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 …
The soaring mercury beat all available records to make today the hottest day in the Queen of the Hills in 170 years. As the temperature climbed to 32.4
An increase in atmospheric carbon dioxide (CO2) concentration influences climate both directly through its radiative effect (i.e., trapping longwave radiation) and indirectly through its physiological effect (i.e., reducing transpiration of land plants). Here we compare the climate response to radiative and physiological effects of increased CO2 using the National Center …
AZERA RAHMAN NEW DELHI Even as his employers disappear into their air-conditioned home or zoom out of the gates in their cool sedans, Shiva Kumar, a 64-year-old guard, has always been satisfied with a table fan to tackle Delhi
global land and ocean surface temperatures for the period between January and April were the warmest on record, and April was the warmest individual month ever, America
Planted in the early 20th century to help control erosion, kudzu is a fast-growing invasive legume that fixes atmospheric nitrogen at a high rate. The Asian native is not just swallowing landscapes and altering ecosystems in the southeastern United States, the plant may also increase ozone pollution. Jonathan Hickman et …
The daily net ecosystem CO2 exchange, diurnal pattern of net CO2 exchange and ecosystem respiration of Cenchrus ciliaris grassland in semi-arid region were studied during July 2008
THIRUVANANTHAPURAM: A permanent system, with its headquarters at the Agriculture Directorate, will be set up in the Agriculture Department to issue warnings to the farmers according to the predictions made by the Meteorological Department, Agriculture Minister Mullakkara Retnakaran has said. Speaking at a meeting convened for preparing short-term as well …
Clouds with aerosols conspire to block and reflect away sunlight over the Indian subcontinent, a new research claims. This results in what is called 'solar dimming' lessening the amount of sunlight that reaches Indian soil. "Dimming affects climate change by reducing surface temperature and weakening the hydrological cycle, which in …
The Indian Space Research Organisation (ISRO), as part of the Indo-French Space Collaboration, is planning to launch a satellite for climate research in a year's time. The
We investigated the mid stream water quality of Ganga river as influenced by aerially - driven heavy metals at Varanasi, India. Twelve sampling stations were selected along a 20 km long stretch of the river. Mid stream sub-surface water samples collected at fortnightly intervals from all the sites were acid …
Eli Kintisch SULFATE AEROSOLS Aerosol pollution has helped keep the planet cool by blocking sunlight Unlike carbon dioxide, which persists in the atmosphere for centuries, aerosols last for a week at most. So cutting them would probably accelerate global warming rapidly what would happen if nations instituted all existing pollution …
Sandip Das New Delhi: Discounting fears that high temperature across key wheat-growing regions of the country since the first week of this month could impact the standing crop, a senior official with the ministry of agriculture on Sunday said production is not likely to be adversely impacted, as harvesting have …
Vinson Kurian How are western disturbances, currently busy creating weather over northwest India, positioned relative to the track of the volcanic cloud originating from Iceland? The question assumed importance in the context of reports that a south-southeast-bound
In the polar tropospheric boundary layer, reactive halogen species (RHS) are responsible for ozone depletion as well as the oxidation of elemental mercury and dimethyl sulphide. After polar sunrise, air masses enriched in reactive bromine cover areas of several million square kilometers. Still, the source and release mechanisms of halogens …
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: …
