US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us. Published today, Tuesday 5 July, in IOP Publishing's journal Environmental Research Letters, the study has revealed the potentially devastating effects that high carbon emissions could have on our climate. Little attention has previously been paid to the upper bound range of future...

Although greenhouse gas emissions have soared in the last decade, the rise in global warming trends has halted, at least temporarily, according to a new US-led study. This may lead to a more rapid warming in average global temperatures once emissions are reduced with crackdowns on pollution in emerging Asian factories, Reuters is reporting. Scientists claim that world temperatures did not rise between 1998 to 2008, while emissions of carbon dioxide from burning fossil fuel grew by nearly a...

A United Nations report released Tuesday calls for fast action on reducing emissions of black carbon, ground level ozone and methane to help limit near term global temperature rise preventing the Earth from overheating, reports AFP. Fast action could also reduce losses of mountain glaciers and reduce projected warming in the Arctic over the coming decades by as much as two thirds. Cutting out these pollutants now could also boost global food output and save millions of human lives lost to...

Researchers from six countries are in the Arctic studying the potential role that soot, or black carbon, has on the rapidly changing Arctic climate. Although the Arctic is typically viewed as a vast white wasteland, scientists believe a thin layer of soot is causing it to absorb more heat. They want to find out if that is the main reason for the recent rapid warming of the Arctic, which could have an impact on the world's climate for years to come. Black carbon is produced by vehicle...

Scientists have known for decades that black carbon aerosols add to global warming. These airborne particles made of sooty carbon are believed to be among the largest man-made contributors to global warming because they absorb solar radiation and heat the atmosphere. New research from Carnegie's Long Cao and Ken Caldeira, along with colleagues George Ban-Weiss and Govindasamy Bala, quantifies how black carbon's impact on climate depends on its altitude in the atmosphere. Their work, published...

Cutting Scotland's greenhouse gas emissions by a half within 20 years is achievable, a study suggests Cutting Scotland's greenhouse gas emissions by a half within 20 years is achievable, a study suggests. Scientists say greener transport and cleaner power generation could help deliver big savings on CO2 emissions. The researchers say the use of smart meters for homes and businesses, improved recycling, and greener building designs could make a difference. They also recommend carbon capture...

A new analysis, published last week and conducted by a team of scientists led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, shows stricter vehicle emission standards would yield major health, agricultural, and climate benefits. Shindell and colleagues used a comprehensive computer model and climate simulator -- one of the first capable of accounting for the role of short-lived particles expelled in vehicle fumes called aerosols -- that shows vehicle...

Polluted snow causes early runoff, stronger monsoons in Asia In some cases, soot "“ the fine, black carbon silt that is released from stoves, cars and manufacturing plants "“ can pack more of a climatic punch than greenhouse gases, according to a paper published in the journal Atmospheric Chemistry and Physics. Researchers at the Department of Energy's Pacific Northwest National Laboratory, the University of Michigan and NOAA found that soot landing on snow on the massive Tibetan...

Black carbon (BC) and tropospheric ozone (O3) are harmful air pollutants that also contribute to climate change. The emission of both will continue to negatively impact both human health and climate. While our scientific understanding of how black carbon and tropospheric ozone affect climate and public health has significantly improved in recent years, the threat posed by these pollutants has catalysed a demand for knowledge and concrete action from governments, civil society, United Nations...
