5.0 02 There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and […]

5.0 01 Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past […]

5.0 01 Stress and depression can take a combined toll on the heart, creating a “psychosocial perfect storm” that dramatically increases the risk of death from heart disease, new research has found. A study involving nearly 4,500 adults with coronary artery disease found those who also suffered from significant stress and depression were nearly 50 percent more likely to die […]

4.0 02 Human-like sounds made by a captive beluga whale suggest that cetaceans could learn to mimic our voices, and perhaps even converse with us. Researchers at the National Marine Mammal Foundation first noticed in the 1980s that one of their whales was attempting to copy the speech patterns of his handlers and they began recording his human-like vocalizations. Recently, […]

5.0 01 European researchers have once again warned that the thinning of the Antarctic ice shelf means that the flow of glaciers on the frozen continent could accelerate, with a consequent rise in sea levels. They examine, in two separate studies, the increasingly precarious state of some of the ice shelf. When the shelf, consisting of ice floating on the […]

0.0 00 10 myths about global warming, and what the science really says. THE REASONS FOR raising doubts about the human causes of global warming, explains Skeptical Sciences John Cook, are often political rather than scientific. Cook hears from climate change skeptics that ‘“its all a liberal plot to spread socialism and destroy capitalism. However, what is causing global warming […]

4.3 03 The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it […]

5.0 02 According to a new study by Nasa, Antarctica’s Larsen B ice-shelf is on course to completely disintegrate within the next five years. Studies show that the 10,000-year-old ice shelf, after partially collapsing in 2002, is “quickly weakening.” “These are warning signs that the remnant is disintegrating,” said Ala Khazendar of Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
