Residential sector key source of PM2.5 pollution in north India: Study

Pollution in east, north and central Indian cities primarily comes from residential and transportation sectors, while in western India, industry and energy are the main contributors to local PM2.5 pollution, a study has found. Published in the journal Modeling Earth Systems and Environment, the study also found that PM2.5 pollution in cities in south India majorly comes from the industry and residential sectors. Researchers from the Indian Institute of Tropical Meteorology, Maharashtra, and the Indian Institute of Technology Roorkee, analysed pollution levels in 53 cities, having more than a million population during the winter of 2015-2016. Residential emissions -- from burning biomass for cooking and heating -- were found to be the leading contributor to local PM2.5 pollution in Srinagar (68 per cent), Varanasi (37 per cent), Allahabad (34 per cent) and Kanpur (33 per cent). The transportation sector's contribution to local PM2.5 pollution was found to be higher in north Indian .

Man-made products could be storing 8.4 bn tonnes of carbon: Study

About 8.4 billion tonnes of carbon is estimated to have been accumulated and stored in long-lasting products from around the world made by humans, such as plastics and buildings, between 1995 and 2019, according to a study. Researchers at the University of Groningen in the Netherlands said this 'fossil carbon' added to the 'technosphere' -- the sum of all human-made objects, both in use and discarded -- equals around 93 per cent of carbon dioxide emissions from around the world in 2019. They added that the carbon locked up in the 'technosphere' has a huge potential to add to greenhouse gas emissions. Increasing the lifetime of products and recycling rates are two ways to reduce the amount of fossil carbon entering waste streams, the researchers suggested. "Over these 25 years (1995-2019), 8.4 billion tons of fossil carbon have accumulated, with approximately 0.4 billion tons added each year, with a huge potential for further contribution to anthropogenic greenhouse gas emissions,"

Pak's Punjab govt uses artificial rain in cities to combat pollution

Pakistan's Punjab government on Friday declared smog a health crisis" and used artificial rain in several cities across the province in an effort to combat its hazardous levels, as millions reported breathing problems and other respiratory issues over the past month. This is the second time the Punjab government went for artificial rain. In December last year, the government had a successful cloud seeding experiment in Lahore. "The cloud seeding experiment conducted in Jhelum, Chakwal, Talagang, and Gujar Khan cities of Punjab resulted in rainfall in Jhelum and Gujar Khan on Friday," the Punjab government said in a late night statement. It said it held a successful trial of artificial rain using local technology. "Cloud seeding was carried out at 2pm Friday and within hours, it rained in Jhelum and Gujar Khan. There is also a strong likelihood of rainfall in Lahore after this experiment. The artificial rainfall will significantly help reduce smog," it said. Earlier in the day, ...

Fossil emissions to hit record this year, India's share to rise: Report

India's fossil fuel emissions are projected to rise by 4.6 per cent in 2024, while China could see a marginal rise of 0.2 per cent, according to new research by a group of international scientists. The report, unveiled during the UN climate conference or COP29 in Azerbaijan's Baku on Wednesday, stated that global carbon emissions from fossil fuels could reach 37.4 billion tonnes, an increase of 0.8 per cent from 2023 levels. Atmospheric CO2 levels are projected to reach 422.5 parts per million in 2024, which is set to become the warmest year on record. This is 2.8 parts per million higher than in 2023 and 52 per cent above pre-industrial levels. "The impacts of climate change are becoming increasingly dramatic, yet we still see no sign that burning of fossil fuels has peaked," said Professor Pierre Friedlingstein of Exeter's Global Systems Institute, who led the study. According to a UN report released last month, India's greenhouse gas emissions surged by 6.1 per cent in 2023, ...

UN climate talks to focus on money to help poor nations cut pollution

A complex international two-week-long game of climate change poker is convening. The stakes? Just the fate of an ever-warming world. Curbing and coping with climate change's worsening heat, floods, droughts and storms will cost trillions of dollars and poor nations just don't have it, numerous reports and experts calculate. As United Nations climate negotiations started Monday in Baku, Azerbaijan, the chief issue is who must ante up to help poor nations and especially how much. The numbers are enormous. The floor in negotiations is the $100 billion a year that poor nations based on a categorization made in the 1990s now get as part of a 2009 agreement that was barely met. Several experts and poorer nations say the need is $1 trillion a year or more. It's a game with high stakes, said Climate Analytics CEO Bill Hare, a physicist. Right now the fate of the planet depends very much on what we're able to pull off in the next five or 10 years. But this year's talks, known as COP29, wo
