Mar. 28, 2016 — Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. These dramatic trends and global sea-level rise are linked, according to a new ... read more

Ancient Bones Point to Shifting Grassland Species as Climate Changes

Mar. 25, 2016 — More rainfall during the growing season may have led to one of the most significant changes in Earth's vegetation in the distant past, and similar climate changes could affect the distribution ... read more

Mar. 24, 2016 — The launch of the GOES-R geostationary satellite in Oct. 2016 could herald a new era for predicting hurricanes, according to researchers. The wealth of information from this new satellite, at time ... read more

Mar. 24, 2016 — A new study reveals that much more is happening at the microscopic level of cloud formation than previously thought. The findings could help improve the accuracy of climate change ... read more

Mar. 18, 2016 — Solar fuels, clean fuels from sunlight, water and CO2, form an attractive way for storing solar energy in hydrogen or hydrocarbons, for example. The efficiency of this technology still needs a ... read more

Mar. 18, 2016 — Using a new approach scientists have found that China's "climate responsibility", is not as significant as initially estimated. However, rather paradoxically, the latter country's ... read more

Mar. 16, 2016 — Nearly four billion years ago, life arose on Earth. Life appeared because our planet had a rocky surface, liquid water, and a blanketing atmosphere. But life thrived thanks to another necessary ... read more

Oil and Natural Gas Boom Causes Methane Emissions to Increase

Mar. 15, 2016 — Like carbon dioxide, methane is one of the most important greenhouse gases. After a period of stagnation around 2000, atmospheric methane concentrations started to rise again in 2007. So far, the ... read more

Mar. 15, 2016 — Shifting winds may explain why long-term fluctuations in North Atlantic sea surface temperatures have no apparent influence on Europe's wintertime temperatures. The findings could also have ... read more

Mar. 14, 2016 — As the Earth emerged from its last ice age several thousand years ago, atmospheric carbon dioxide increased and further warmed the planet. Scientists have long speculated that the primary source of ... read more

Aviation and Volcanic Ash: Don't Build Model on Sand

Mar. 14, 2016 — Volcanic ash can damage jet engines, and volcanologists have developed a new empirical model for assessment of the risk. Their results show that tests using sand do not reflect the behavior of ash in ... read more

European Clean Air Policies Unmask Arctic Warming by Greenhouse Gases

Mar. 14, 2016 — The drastic cut in sulfate particle emissions in Europe partly explains the amplified Arctic warming since the 1980s, shows a new study. Sulfate emissions, which cause, for example, acid rain, peaked ... read more

Mar. 11, 2016 — A supercondenser has been developed that can be charged by the sun. It contains no expensive or hazardous materials, has patents pending, and it should be fully possible to manufacture it on an ... read more

Wildland Fire Emissions Worse in Polluted Areas

Mar. 11, 2016 — When plant matter burns, it releases a complex mixture of gases and aerosols into the atmosphere. In forests subject to air pollution, these emissions may be more toxic than in areas of good air ... read more

Eyeing Climate Change, Satellites Provide Missing Information

Mar. 9, 2016 — Scientists develop a new method to measure the impact of pollution on global warming and reduce the gaps in knowledge on climate ... read more

Mar. 3, 2016 — Clouds are notoriously hard to simulate in computer programs that model climate. A new study suggests why -- either clouds are more variable than scientists give them credit for, or those bright ... read more

Mar. 3, 2016 — Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely ... read more

Are Developments in Technology Improving Air Quality?

Mar. 2, 2016 — The London fog episode of the 1950s and the thousands of premature deaths that followed catalysed a series of attempts to improve air quality. According to author Philip K. Hopke, there have been ... read more
