Order of the National Green Tribunal in the matter of News Item titled “CSE report finds dangerous increase in ozone pollution across urban India” appearing in Down to Earth dated 06.08.2024. The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
Short-term exposure to ozone has been associated with increased daily mortality. The shape of the concentration–response relationship—and, in particular, if there is a threshold—is critical for estimating public health impacts.
There are many ways to harm your respiratory system such as smoking or breathing in asbestos. For urbanites living in cities across Europe, merely living and breathing in the city can be bad. A new study released by the European Environment Agency (EEA) found that most residents of European cities …
Microscopic particles, among the most harmful forms of air pollution, are still found at dangerous levels in Europe, although law has cut some toxins from exhaust fumes and chimneys, a European Environmental Agency (EEA) report said on Monday. On average, air pollution is cutting human lives by roughly eight months …
The Climate Action Tracker has updated our analysis on national greenhouse gas emission reduction proposals for 2020 under the international climate negotiations. We find that governments are taking action to implement their reduction proposals, but many are set to fail in reaching those proposals. Recent highlights include the agreed link …
The World Meteorological Organization (WMO) and the International Global Atmospheric Chemistry (IGAC) project have released a report, titled “Impacts of Megacities on Air Pollution and Climate.” The report provides an initial assessment of available information on air pollution and climate impacts in megacities globally. The report concludes that, unless city …
Washington, DC 28 August 2012 – Arctic sea ice has hit record lows with weeks still to go in the melt season, an indication of accelerating global warming. Arctic sea ice has reached the lowest level ever observed in the three decades since polar cap observations began, according to scientists …
The observed presence of water vapor convectively injected deep into the stratosphere over the United States can fundamentally change the catalytic chlorine/bromine free-radical chemistry of the lower stratosphere by shifting total available inorganic chlorine into the catalytically active free-radical form, ClO. This chemical shift markedly affects total ozone loss rates …
During the week leading up to the Olympic Games, London experienced its worst ozone episode for six years. Fortunately fresh westerly winds began to clear London's air pollution just before the opening ceremony. On 21 July high pressure moved over the UK and air began to slowly circulate over southern …
California's air regulator this week defended its decision to allow emitters to use offset credits in the state's forthcoming emissions trading system, refuting claims made in a lawsuit by two green groups that there is no way to ensure the environmental integrity of those projects. The plaintiffs who brought the …
Hong Kong has urged people to stay indoors as the city chokes under the worst cloud of man-made air pollution the city has recorded, officials say. Air pollutant readings on Thursday broke records going back to 1999, except for levels reached when a natural dust storm hit the southern Chinese …
What is the world wide trend in air pollution? On the surface North America and Europe have been gradually improving. However, that is due to often moving industry to other countries such as China or India where air pollution is a bit more of a problem. Most of the world's …
This study looks at changes in North Atlantic tropical storm occurrence in the twenty-first century, and finds that over the first half of the century, storm frequency increases were caused by radiative forcing changes, not increasing carbon dioxide. The chaotic nature of the climate system and the climate response to …
The observed presence of water vapor convectively injected deep into the stratosphere over the United States fundamentally changes the catalytic chlorine/bromine free radical chemistry of the lower stratosphere by shifting total available inorganic chlorine into the catalytically active free-radical form, ClO. This chemical shift markedly affects total ozone loss rates …
To provides an overall framework for thinking about the construction of carbon markets, we adopt James Der Derian's ‘virtuous war’ theory to develop an argument about carbon as a virtuous commodity. This refers to the close affinity between virtuality and virtue – the technological and the ethical – in the …
This is the 22nd annual edition of the State of the Climate series, from its origin as NOAA’s Climate Assessment, and the 17th consecutive year of its association with the Bulletin of the American Meteorological Society. Its primary goals are to document the weather and climate events of the year …
Volatile organic compounds (VOCs) are ubiquitous atmospheric constituents of both anthropogenic and natural origin. VOCs are important precursors of tropospheric ozone (O3), and can impact air quality and global climate. Most of primary VOCs and their oxidized products makeup a major fraction of secondary pollutants in urbanized regions. Due to …
Steady-state and dynamic gas exchange responses to ozone visible injury were investigated in an ozone-sensitive poplar clone under field conditions. The results were translated into whole tree water loss and carbon assimilation by comparing trees exposed to ambient ozone and trees treated with the ozone-protectant ethylenediurea (EDU). Steady-state stomatal conductance …
With car ridership set to boom by 106 per cent, Delhi's air pollution and congestion crisis is bound to worsen, warns a survey by Centre for Science and Environment (CSE). Calling for transport planning that hinges on sustainability, equity, and a people-centric approach, the CSE survey, released on World Environment …
“At this rate, the Capital will be gasping for breath by 2021” Delhi's air quality is worsening and if urgent action is not taken we will have a serious problem at hand, warns Centre for Science and Environment's latest report card. “The summer of 2012 is a grim reminder of …
On World Environment Day, this report card from Centre for Science and Environment (CSE) warns that Delhi's air pollution and congestion crisis will worsen this decade if urgent action is not taken and calls for radical improvements in public transport. On this World Environment Day, Centre for Science and Environment …
