WMO provisional statement on the status of the global climate in 2016

It is very likely that 2016 will be the hottest year on record, with global temperatures even higher than the record-breaking temperatures in 2015. Preliminary data shows that 2016’s global temperatures are approximately 1.2° Celsius above pre-industrial levels, according to an assessment by the World Meteorological Organization (WMO). Global temperatures …

Short-lived climate pollutants (SLCPs): an analysis of the EIB’s policies, procedures, impact of activties and options for scaling up mitigation efforts

The European Investment Bank (EIB) has completed an analysis of its standards, criteria and procedures in relation to short-lived climate pollutants. The EIB also looked into the projects and sectors that it finances, the impacts they have on SLCP emissions and where the bank can scale up financing of projects …

Emissions of carbon tetrachloride from Europe

Carbon tetrachloride (CCl4) is a long-lived radiatively active compound with the ability to destroy stratospheric ozone. Due to its inclusion in the Montreal Protocol on Substances that Deplete the Ozone Layer (MP), the last two decades have seen a sharp decrease in its largescale emissive use with a consequent decline …

Breathing cleaner air: ten scalable solutions for Indian cities

Motivated by the current leadership for a Clean India, a self-organized task force has developed a set of ten scalable solutions to clean the air. They have synthesized available data on sources of air pollution, its transport over long distances, its impact on public health, food production, regional climate, to …

India takes R&D route to find alternatives to climate-damaging refrigerants HFCs

Environment ministry on Thursday announced an ambitious collaborative R&D; programme to develop next generation sustainable refrigerant technologies as alternatives to the climate-damaging hydrofluorocarbons (HFCs). The announcement came a day before the International Ozone Day. Though HFC is not an ozone-depleting chemical substance like other refrigerants, it has huge potential to …

Antarctic ozone depletion between 1960 and 1980 in observations and chemistry-climate model simulations

The year 1980 has often been used as a benchmark for the return of Antarctic ozone to conditions assumed to be unaffected by emissions of ozone depleting substances (ODSs), implying that anthropogenic ozone depletion in Antarctica started around 1980. Here, the extent of anthropogenically-driven Antarctic ozone depletion prior to 1980 …

Multi-model evaluation of short-lived pollutant distributions over east Asia during summer 2008

The ability of seven state-of-the-art chemistry–aerosol models to reproduce distributions of tropospheric ozone and its precursors, as well as aerosols over eastern Asia in summer 2008, is evaluated. The study focuses on the performance of models used to assess impacts of pollutants on climate and air quality as part of …

Thousands of lives could be saved in California by stricter air pollution limits, study finds

More than 2,000 Southern Californians die early each year from polluted air, and the region would benefit the most of anywhere in the country from reducing ozone and fine particle pollution below current federal limits, a new study has found. The analysis by scientists at New York University and the …

Co-benefits of global and regional greenhouse gas mitigation for US air quality in 2050

Policies to mitigate greenhouse gas (GHG) emissions will not only slow climate change but can also have ancillary benefits of improved air quality. Here we examine the co-benefits of both global and regional GHG mitigation for US air quality in 2050 at fine resolution, using dynamical downscaling methods, building on …

Dirty fuel crackdown won't prevent thousands of deaths from air pollution

Air pollution would cause the deaths of at least 2500 people across Sydney and Melbourne in the year 2030 even if the federal government swiftly clamped down on poisonous car fuels, a government-commissioned report has found. The alarming figures increase pressure on the Turnbull government to introduce cleaner fuel standards …

Lethal and illegal: London’s air pollution crisis

Air pollution is a huge and growing public health problem for the UK, and for London in particular. Presenting innovative new modelling that illustrates the scale of both the problem and the policy changes required to remedy it at the European, national and local levels, this report presents detailed analysis …

Air pollution hampers bees' ability to forage

Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators such as bees use to locate needed food, says a new study. The pollution-modified plant odours can confuse bees and, as a result, bees' foraging time increases and pollination efficiency decreases, the study said. This happens because …

European Union emission inventory report 1990–2014 under the UNECE Convention on Long-range Transboundary Air Pollution (LRTAP)

This document is the annual European Union (EU) emission inventory report to the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (CLRTAP). The report and its accompanying data constitute the official submission by the European Commission (EC) on behalf of the EU as a Party …

Antarctic ozone hole has finally started to heal, scientists report

In a major new paper in the influential journal Science, a team of researchers report strikingly good news about a 30-year old environmental problem. The Antarctic ozone "hole" - which, when it was first identified in the mid-1980s, focused public attention like few other pieces of environmental news - has …

Premature mortality in India due to PM2.5 and ozone exposure

This bottom-up modeling study, supported by new population census 2011 data, simulates ozone (O3) and fine particulate matter (PM2.5) exposure on local to regional scales. It quantifies, present-day premature mortalities associated with the exposure to near-surface PM2.5 and O3 concentrations in India using a regional chemistry model. We estimate that …

Multiple threats to child health from fossil fuel combustion: Impacts of air pollution and climate change

Approaches to estimating and addressing the risk to children from fossil fuel combustion have been fragmented, tending to focus either on the toxic air emissions or on climate change. Yet developing children, and especially poor children, now bear a disproportionate burden of disease from both environmental pollution and climate change …

India rejects US study on pollution in India

The central government on Wednesday rejected a study on pollution published in the Geophysical Research Letters Journal of the American Geophysical Union. "We reject the claims made in the so-called research article that each Indian loses six years of his/her life because of pollution. The Ministry of Earth Sciences does …

The economic consequences of outdoor air pollution

Air Pollution could cause 6-9 million premature deaths by 2060, with India and China facing threat of maximum number of such mortalities, according to an OECD report. This report provides a comprehensive assessment of the economic consequences of outdoor air pollution in the coming decades, focusing on the impacts on …

Study shows Delhi tops list in number of life years lost: Exposure to PM 2.5 reduces life expectancy, capital bears brunt

The figures in Delhi — the highest among all states — are also double the national average of reduction in life expectancy which is 3.3 years. Air pollution in India can cause about half a million premature mortalities every year, and exposure to fine particulate matter in India reduces life …

Delhi’s pollution takes 6 yrs from your life, says study

Pune: Delhi might be paying the steepest price for its air pollution with life expectancy dropping by 6.4 years while Uttar Pradesh and Maharashtra are likely to account for the highest number of premature deaths in India, a study by the Indian Institute of Tropical Meteorology has revealed. Conducted by …
