Therefore, the study concludes, we can say with very high confidence that the recent Texas and Moscow heat waves were "caused" by global warming because the probability of them occurring without global warming is negligible. Furthermore, they add that "Additional global warming in the next 50 years, if business-as-usual fossil fuel emissions continue, is expected to be at least 1C. In that case, the further shifting of the anomaly distribution will make +3-sigma anomalies the norm and +5-sigma anomalies will be common."

The "Visible Pinball" as it is called, is the centerpiece of a new "Pinball Science" museum exhibit that NBAM is developing. The game will be unveiled to the public for the first time at the Pacific Pinball Exposition that is being held at the Marin Civic Center in San Rafael, California on October 5 to 7. "The purpose of the Visible Pinball is to teach kids about electricity and physics in a really fun way", Michael said. "It's also a blast to play!" he added. The Visible Pinball is based on a 1976 "electro mechanical" pinball machine called "Surf Champ". All of the wooden parts of the game and its backglass have been replaced with clear Plexiglas so that the mechanisms that drive the machine are visible to the player. Pop bumpers, drop targets, roll-over switches and other pinball mechanisms can be viewed as they operate. Pinball games made prior to 1977 did not use electronic components or computers so all of the functions are based on mechanical and electro-mechanical parts.
