Carbon dioxide benchmark hits new heights, scientists worry. (click title to open news story)
CNN.com (March 23, 2014) --"It's a new record, but one scientists aren't thrilled about hitting. A benchmark reading of heat-trapping carbon dioxide in Earth's atmosphere hit a fresh peak in the past two weeks, and it's expected to stay at or above a milestone level for some time. Instruments on Hawaii's Mauna Loa observatory first recorded carbon dioxide levels above 400 parts per million last May, peaking at 400.5. This year, the seasonally fluctuating number has crossed 401 ppm three times this month and hit a record 401.6 on March 12, said Ralph Keeling at the Scripps Institution of Oceanography in San Diego. That's a figure well above pre-industrial levels and perhaps not seen since before the rise of humanity." - Matt Smith

Big Bang breakthrough announced; gravitational waves detected. (click title to open news story)CNN.com (March 18, 2014) - "There's no way for us to know exactly what happened some 13.8 billion years ago, when our universe burst onto the scene. But scientists announced Monday a breakthrough in understanding how our world as we know it came to be. If the discovery holds up to scrutiny, it's evidence of how the universe rapidly expanded less than a trillionth of a second after the Big Bang. 'It teaches us something crucial about how our universe began,' said Sean Carroll, a physicist at California Institute of Technology, who was not involved in the study. 'It's an amazing achievement that we humans, doing science systematically for just a few hundred years, can extend our understanding that far.' What's more, researchers discovered direct evidence for the first time of what Albert Einstein predicted in his general theory of relativity: Gravitational waves." - Elizabeth Landau
