Consumer products' air quality impact 'underestimated'

Consumer products' air quality impact 'underestimated'

Science
US research has found that chemicals in everyday household products are now a key contributor to city air pollution, rivalling some vehicle emissions. The study, led from Colorado University, focussed on so-called volatile organic compounds (VOCs). These are contained in petroleum-based products such as cleaning fluids and paints, and when they get into the air can form particles that affect health. The scientists say the sources of non-vehicle VOCs have been underestimated. This appears a somewhat surprising result because by weight, we use far more fuel than we do these other chemical products. 'Reduce your use'About 95% of raw oil goes into the production of fuels, whereas roughly only 5% is refined for use in chemicals that are included in the likes of deodorants, pesticides, and adhes...
Asteroid impact plunged dinosaurs into catastrophic 'winter'

Asteroid impact plunged dinosaurs into catastrophic 'winter'

Science
Scientists say they now have a much clearer picture of the climate catastrophe that followed the asteroid impact on Earth 66 million years ago. The event is blamed for the demise of three-quarters of plant and animal species, including the dinosaurs. The researchers' investigations suggest the impact threw more than 300 billion tonnes of sulphur into the atmosphere. This would have dropped temperatures globally below freezing for several years. Ocean temperatures could have been affected for centuries. The abrupt change explains why so many species struggled to survive. "We always thought there was this global winter but with these new, tighter constraints, we can be much more sure about what happened," Prof Joanna Morgan, from Imperial College London, told BBC News. The new assessment is ...
Equifax raises the impact of US data breach

Equifax raises the impact of US data breach

Technology
Equifax has revealed 2.5 million more Americans than previously thought may have had information compromised in a huge cyber security breach at the firm. The credit report giant said on Monday about 145.5 million of its US customers might have been affected, up from a previous estimate of 143 million. The update came a day before former boss Richard Smith testifies in Congress about the attack.Mr Smith apologised ahead of the hearing for the firm's failings.Critics say the company failed to take proper steps to guard information - such as Social Security numbers, birth dates and addresses - and waited too long to inform the public.Equifax disclosed the attack last month, estimating that about 400,000 Britons and 100,000 Canadians may also have had data compromised.On Monday, the firm raise...
Study shows impact of global warming on coffee production

Study shows impact of global warming on coffee production

Science
Sept. 11 (UPI) -- A recent study by the University of Vermont found global warming could reduce coffee growing areas in Latin America by as much as 88 percent by 2050.Researchers from the University of Vermont's Gund Institute for Environment found climate change will continue to negatively impact coffee production, as well as bee populations, essential to coffee farming."Coffee is one of the most valuable commodities on earth, and needs a suitable climate and pollinating bees to produce well," Taylor Ricketts, director of the UVM's Gund Institute for Environment, said in a press release. "This is the first study to show how both will likely change under global warming -- in ways that will hit coffee producers hard."The study, published today in the Proceedings of the National Academy of S...
Arctic voyage finds global warming impact on ice, animals

Arctic voyage finds global warming impact on ice, animals

Technology
The email arrived in mid-June, seeking to explode any notion that global warming might turn our Arctic expedition into a summer cruise. "The most important piece of clothing to pack is good, sturdy and warm boots. There is going to be snow and ice on the deck of the icebreaker," it read. "Quality boots are key." The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North. But once the ship entered the fabled Northwest Passage between the Atlantic and the Pacific, there would be nowhere to stop for supplies, no port to shelter in and no help for hundreds of miles if things went wrong. A change in the weather might cause the mercury to drop ...
