Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. Emitted by natural and human sources, aerosols can directly influence climate by reflecting or absorbing the sun's radiation. The small particles also affect climate indirectly by seeding clouds and changing cloud properties, such as...

NASA scientist and leading climate expert, James Hansen, said on Wednesday that more drastic measures may be needed in order to change the course of climate change policy. "The first action that people should take is to use the democratic process. What is frustrating people, me included, is that democratic action affects elections but what we get then from political leaders is greenwash," said Hansen as he headed to a protest against power firm E.ON in Coventry. "The democratic process is...

Strong winters with bitter cold and record snowfall during the last two years have led some to doubt whether the global climate is truly warming.  Meanwhile, a new study by researchers at the University of Wisconsin-Milwaukee could turn the climate change world upside down. The scientists used a math application known as "synchronized chaos," and applied it to climate data obtained over the past century. "Imagine that you have four synchronized swimmers and they are not holding hands...

Climate change skeptics meeting at an annual conference in New York Monday are showing signs of internal disputes and weakening support, observers say. The three-day International Conference on Climate Change, organized each year by the nonprofit Heartland Institute, which seeks deregulation and unfettered markets, serves as a platform for those who dispute the position of the Obama administration and Democratic lawmakers who cite science pointing to human activity as the cause of global...

Researchers declared Monday that many damaging effects of climate change are already basically irreversible, warning that even if carbon emissions can somehow be halted temperatures around the globe will remain high until at least the year 3000. "People have imagined that if we stopped emitting carbon dioxide the climate would go back to normal in 100 years, 200 years; that's not true," climate researcher Susan Solomon said in a teleconference. Solomon, a senior NOAA scientist, also said that...

Some 2,000 scientists contributed to the Nobel Peace Prize-winning IPCC report on global warming. Next week, the local contingent will be honored. On the wall of Professor Kirk Smith's office in the School of Public Health hangs an embossed certificate honoring his contributions to the United Nations' Nobel Peace Prize-winning climate-change organization. Because of his groundbreaking work on the deleterious health effects of air pollution caused by indoor cooking and heating fuels around the...

Scientist James Hansen says we're toast if we don't take drastic measures against global warming ("Climatologist sounds warning," June 24). Is this the top NASA scientist who doctored temperature stats, and when asked why he had lied he said it was because we need to get people's attention? Al Gore gave the same excuse for his lies, and he attained his goal. A Nobel and an Oscar are a lot of attention. Jennifer Zapata Highland (c) 2008 Deseret News (Salt Lake City).

Scientists in the U.K. have reported evidence that further refutes one theory of global climate change.In the heated debate over global warming, there is an opposing idea, called the cosmic ray theory, which contends that climate change is simply caused by cosmic rays coming from the sun.However, researchers at Lancaster University reported in the Institute of Physics journal that there has been no correlation between solar activity and the Earth's climate.Pioneered by Dr. Henrik Svensmark at...
