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 …
One potential impact from greenhouse-gas emissions is increasing damage from extreme events. Here, we quantify how climate change may affect tropical cyclone damage. We find that future increases in income are likely to double tropical cyclone damage even without climate change. Climate change is predicted to increase the frequency of …
Chemical ozone destruction occurs over both polar regions in local winter–spring. In the Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an ozone hole every year, whereas in the Arctic, ozone loss is highly variable and has until now been much more limited. Here we demonstrate that chemical …
Sending satellites to monitor the atmosphere is fundamental to weather and climate research. So why is the United States making such a meal of it? (Editorial)
For the first time in India, scientific tests will be conducted on the Himalayan glaciers in Uttarakhand to measure the impact of carbon soot on glaciers. Scientists from Indian Space Research Organisation, Uttarakhand Space Application Centre and Space Physics Laboratory, Thiruvananthapuram, will conduct these tests slated to begin September 24, …
London: There will be an unexpected sight high in the skies over the British county of Norfolk nextmonth: A huge balloon attached to the ground by a giant hosepipe. It isn’t obvious, but it is the first small step in an experiment which aims to re-create the cooling effect of …
Land use and land cover changes affect the partitioning of latent and sensible heat, which impacts the broader climate system. Increased latent heat flux to the atmosphere has a local cooling influence known as ‘evaporative cooling’, but this energy will be released back to the atmosphere wherever the water condenses. …
In the context of climate change and its impact on sectors like agriculture and health, it is important to examine the changes in the characteristics of temperature extremes of different intensities and duration. In this study, an India Meteorological Department gridded temperature dataset is used to examine the changes in …
An international team of researchers, including physical oceanographers from the Woods Hole Oceanographic Institution (WHOI), has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could significantly influence the ocean's response to climate change in previously unforeseen ways. The current, called the North Icelandic Jet (NIJ), contributes …
Methane and ethane are the most abundant hydrocarbons in the atmosphere and they affect both atmospheric chemistry and climate. Both gases are emitted from fossil fuels and biomass burning, whereas methane (CH4) alone has large sources from wetlands, agriculture, landfills and waste water. Here we use measurements in firn (perennial …
MONITORING air pollution just got simpler. A handy and low-cost instrument has been developed for researchers to measure and analyse soot level in the air. Soot, or black carbon, is the second biggest contributor to global warming after carbon dioxide. It is released in the air by incomplete combustion of …
This document details the Black Carbon Research Initiative launched by India as part of the National Carbonaceous Aerosols Programme (NCAP). This joint initiative of several government ministries & leading research institutions builds on the existing work and sets out the science programme to respond to the scientific questions surrounding Black …
The Ministry of Science and Technology has decided to import super computers to improve weather forecasts in the country. This was stated by Ashwani Kumar, Minister of State for Parliamentary Affairs, Planning and Science and Technology, while addressing a press conference here today. Sources in the Meteorological Department said that …
Charged particles from beyond solar system possibly affect the pace, but the extent is not clear. The role of the cosmic rays has been highlightedin a paper by the former ISRO Chairman, U.R. Rao Dr. Rao points to a nine per cent reduction in the intensity of cosmic rays during …
Scientists claim to have achieved a breakthrough by generating a series of downpours in the deserts of the United Arab Emirates using a new tech nology which is designed to control the weather. A team, employed by the ruler of Abu Dhabi and Pres ident of the UAE, Sheikh Khalifa …
The Ozone Secretariat has released the Scientific Assessment of Ozone Depletion 2010, which presents new and stronger evidence of the effect of stratospheric ozone changes on the Earth’s surface climate, and of the effects of climate change on stratospheric ozone.
Fortunately for us, carbon monoxide (CO)—a toxic gas—is a very minor constituent of the atmosphere. It is produced by incomplete burning of fossil fuels and biomass (such as dry leaves and wood) and by the oxidation of methane and other volatile hydrocarbons in the atmosphere. http://www.sciencemag.org/content/330/6011/1636.summary
We present a 650-year Antarctic ice core record of concentration and isotopic ratios (δ13C and δ18O) of atmospheric carbon monoxide. Concentrations decreased by ~25% (14 parts per billion by volume) from the mid-1300s to the 1600s then recovered completely by the late 1800s. δ13C and δ18O decreased by about 2 …
Nitric oxide reductase (NOR) is an iron-containing enzyme that catalyzes the reduction of nitric oxide (NO) to generate a major greenhouse gas, nitrous oxide (N2O). Here, we report the crystal structure of NOR from Pseudomonas aeruginosa at 2.7 angstrom resolution. The structure reveals details of the catalytic binuclear center. The …
