An apparent hiatus in global warming?
The AGU reports on Dec. 5th that "Global warming first became evident beyond the bounds of natural variability in the 1970s, but increases in global mean surface temperatures have stalled in the 2000s. Increases in atmospheric greenhouse gases, notably carbon dioxide, create an energy imbalance at the top-of-atmosphere (TOA) even as the planet warms to adjust to this imbalance, which is estimated to be 0.5–1 W m-2 over the 2000s. Annual global fluctuations in TOA energy of up to 0.2 W m-2 occur from natural variations in clouds, aerosols, and changes in the Sun. At times of major volcanic eruptions the effects can be much larger. Yet global mean surface temperatures fluctuate much more than these can account for. An energy imbalance is manifested not just as surface atmospheric or ground warming but also as melting sea and land ice, and heating of the oceans. More than 90% of the heat goes into the oceans and, with melting land ice, causes sea level to rise. For the past decade, more than 30% of the heat has apparently penetrated below 700?m depth that is traceable to changes in surface winds mainly over the Pacific in association with a switch to a negative phase of the Pacific Decadal Oscillation (PDO) in 1999. Surface warming was much more in evidence during the 1976–1998 positive phase of the PDO, suggesting that natural decadal variability modulates the rate of change of global surface temperatures while sea-level rise is more relentless. Global warming has not stopped; it is merely manifested in different ways.."
Apollo Conspiracy Theories Debunked In Coming Video Series...
lizabeth Howell of Universe Today reported on Dec. 3rd that " Decades after the last man walked on the moon, Apollo astronauts still get a lot of respect. Some of them have been portrayed in Hollywood movies. Many of them willingly, even in their advanced ages, give public lectures and sign autographs. And already, some observers are wondering about the loss to humanity when the last moonwalker dies. But there is a still a percentage of the population that believes that the astronauts didn’t land on the moon at all. To address this, a couple of experienced hands in filmmaking started a new video series examining and debunking the common conspiracies. Helming the project is Chris Riley, who produced and directed ‘First Orbit’ as well as two BBC biographies of Neil Armstrong and Richard Feynman, and animator Antony Buonomo, who won an Emmy for his work..."
