Opportunity Mars Rover Sets Record Although NASA’s newest Mars rover, Curiosity, has hogged most of the attention since landing on the Red Planet nearly two years ago, Opportunity, the space agency’s Mars rover, which preceded its newer sibling by about 8 years, is the one to set a new record. Opportunity mission officials said that, […]

Rising Levels of Human-Caused Water Vapor in Troposphere will Intensify Climate Change Projections

When it comes to greenhouse gases that contribute most to global warming, most people think of substances such as carbon dioxide, methane or even hydrofluorocarbons. But did you know that, for a while now, scientists have considered the vapor of the most important ingredient in sustaining life on Earth – water – as one of […]

Where Does the World’s E-Waste Go? When you replace a PC, tablet, mobile or any kind of electronic device, do you ever wonder what happens to your old equipment? A new study finds that about 25 percent of all e-waste discarded by developed countries ends up in seven developing nations, posing severe health risks to people […]

New Material Traps Airborne Radioactive Elements

Scientists have come up with a technique that could make cleaning radioactive elements from the air, such as krypton, xenon and radon, easier and cheaper than current technologies. While those radioactive materials naturally mix in the air, the quantities are usually low — typically less than one part per million. The international research team from […]

How Low Will Arctic Sea Ice Go?

British researchers have used a new forecasting method to determine that this year’s melt will be about the same or slightly more than last year, but nowhere near the record arctic sea ice melt set in 2012. This new method of predicting arctic sea ice melt was outlined in Nature Climate Change. Last year, the […]

Scientists Explore Mystery of Antarctica’s Rising

An altered Antarctic landscape is one of the rarely discussed side effects of accelerated ice melting. For years as the ice grew in Antarctica, its weight compressed the ground beneath it. But when the ice melted and this weight was reduced, the ground sprang back, rebounding over time. However, the ground in the Northern Antarctic […]

New Dating System Could Reveal Secrets of Earth’s Ancient Climate

Scientists have a new tool in the quest to learn more about Earth’s ancient climate, including the mechanisms that plunged our planet into and out of ice ages. The new tool is a scientific technique called radiometric krypton dating, which recently allowed researchers to accurately determine the age of a 120,000-year-old Antarctic ice core sample. […]

Study: Air Pollution Over Asia Found to Impact Global Weather

Researchers from Texas, California and Washington recently compared air pollution data provided by the Intergovernmental Panel on Climate Change for the years 1850 through 2000 and found that human-made atmospheric particulates (aerosols) from Asia are having an impact on the Pacific storm track, which is a critical driver of global atmospheric circulation that influences weather […]

Scientists Identify Four New Ozone Depleting Gases in Atmosphere

Scientists have identified four new man-made gases in the atmosphere that they say are helping to destroy Earth’s protective ozone layer. Writing in Nature Geoscience, the researchers said that there are about 74,000,000 kilograms of three newly identified chlorofluorocarbons (CFCs) – compounds that only contain the atoms of carbon, fluorine and chlorine – and one […]
