Order of the National Green Tribunal in the matter of In Re: News Item titled "Nayar river is vanishing - a yatra reveals conservation goes beyond science and policy" appearing in ‘The Down To Earth’ dated 03.06.2025. The original application was registered suo-motu based on the news item titled "Nayar …
The researchers investigate the balance between two mechanisms that remove carbon from the atmosphere and oceans over long timescales—weathering of terrestrial silicates and alteration of the ocean floor. We show that this balance should strongly influence atmospheric oxygen concentration, since it dictates the delivery rate of the ultimate limiting nutrient …
Increasing levels of air pollutants in Asia have recently drawn considerable attention, but the effects of Asian pollution outflows on regional climate and global atmospheric circulation remain to be quantified. Using a multiscale global aerosol–climate model (GCM), we demonstrate long-range transport of the Asian pollution, large resulting variations in the …
Cape Canaveral: Nasa hopes its newest Mars spacecraft lives up to its know-itall name. The robotic explorer called Maven is due to blast off on Monday on a 10-month journey to the red planet. There, it will orbit Mars and study the atmosphere to try to understand how the planet …
The effect of anthropogenic aerosols on cloud droplet concentrations and radiative properties is the source of one of the largest uncertainties in the radiative forcing of climate over the industrial period. This uncertainty affects our ability to estimate how sensitive the climate is to greenhouse gas emissions. Here we perform …
Black carbon (BC) aerosol loadings were measured during the High-performance Instrumented Airborne Platform for Environmental Research Pole-to-Pole Observations (HIPPO) campaign above the remote Pacific from 85°N to 67°S. Over 700 vertical profiles extending from near the surface to max ~14 km altitude were obtained with a single-particle soot photometer between …
This new analysis published by the Bulletin of the American Meteorological Society links human-caused climate change to half of 2012′s extreme weather. Attribution of extreme events is a challenging science and one that is currently undergoing considerable evolution. In this paper are 19 analyses by 18 different research groups, often …
London: Mars had an oxygenrich atmosphere 4,000 million years ago a new Oxford study has found. Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4,000 million years ago — well before the rise of atmospheric oxygen on Earth …
The ozone layer acts like a shield in safeguarding the Earth by preventing the harmful ultraviolet radiations from entering into the atmosphere. Reported damage to the ozone layer in 1985 was a significant milestone in Antarctic science research. The research work played a significant role in generating international socio-political debate …
We investigated the impact of radiosonde data from the ice-free Arctic Ocean obtained by the Japanese R/V Mirai during a cruise in the fall of 2010 on the AFES-LETKF experimental ensemble reanalysis version 2 (ALERA2) data set. The reanalysis used radiosonde data over the ice-free region. Compared with observations, it …
Washington: Sulphur dioxide emissions from moderate volcanoes around the world can mask some of the effects of global warming by 25%, a new study has found. A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between …
The aim of this briefing paper is to provide an overview of the way measurements from space can provide a basis for the understanding and analysis of climate change, highlighting some of the insights that they have provided but also describing the difficulties that are inherent in constructing climate quality …
Phase transitions of atmospheric water play a ubiquitous role in the Earth's climate system, but their direct impact on atmospheric dynamics has escaped wide attention. Here we examine and advance a theory as to how condensation influences atmospheric pressure through the mass removal of water from the gas phase with …
Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment provides an evaluation of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and …
It will help in understanding the process of creation and decay of sunspots Work on the world’s largest solar telescope is likely to commence in the Ladakh region of Jammu and Kashmir by the end of this year. The telescope, with an aperture of two metres, is expected to be …
The increasing trend of rising tropospheric temperatures due to the global climate change is reflected in the efficacy of Indian monsoons too. It is imperative to have a high level, skilled mechanism to monitor and predict this trend to help manage preparedness.
The deliberate injection of particles into the stratosphere has been suggested as a possible geoengineering scheme to mitigate the global warming aspect of climate change. Injected particles scatter solar radiation back to space and thus reduce the radiative balance of Earth. Previous studies investigating this scheme have focused primarily on …
National Aeronautics and Space Administration (NASA) of the United States opened a new chapter in the history of interplanetary exploration on Monday when its $2.5 billion nuclear-powered robot, Curiosity, beamed back pictures from the surface of Mars. The one-tonne mobile lab is the largest rover ever sent to Mars, and …
Cosmic dust that fills space could be playing a part in climate change, scientists say. A study is now trying to ascertain how much of this dust enters the Earth's atmosphere - in a bid to find out how it might affect our climate. Far from being empty, space is …
Washington: The supermassive black hole at the heart of the Milky Way may be devouring asteroids on a daily basis, a new study based on findings by Nasa’s Chandra spacecraft has suggested. The Chandra X-ray Observatory, named in honour of Indian physicist Subrahmanyan Chandrasekhar, has been detecting Xray flares about …
WASHINGTON: Key steps on pollution control would slow down global warming by 0.5 degree Celsius, increase crop yields by 135 million tonnes and prevent thousands of premature deaths every year in India, Nepal and Bangladesh by 2050, reveals a study. The 14 steps, highlighted by NASA scientist Drew Shindell, are …
