The practical impacts of climate change can be hard to predict because of the large scales of time and geography over which changes are occurring. But more frequent jolts in midair could be one way in which individuals will soon literally feel the effects.
A new scientific study says that severe turbulence could become two to three times more common later this century when there is twice as much carbon dioxide in the atmosphere.
‘Our new study paints the most detailed picture yet of how aircraft turbulence will respond to climate change,’ says author Dr. Paul Williams. ‘Even the most seasoned frequent fliers may be alarmed at the prospect of a 149% increase in severe turbulence, which frequently hospitalizes air travelers and flight attendants around the world.’
Climate change is expected to lead to stronger vertical wind shears in the jet stream, at the cruising altitude for most jet aircraft. Wind shears can become unstable and cause turbulence.
Williams used supercomputers simulations that calculate clear-air turbulence along Transatlantic routes in winter and found all turbulence strength levels will increase in a world with twice as much CO2. The computer models show the average amount of light turbulence will increase by 59%, light-to-moderate turbulence by 75%, moderate by 94%, moderate-to-severe by 127%, and severe by 149%.
Ironically, or perhaps poetically, aviation has long been recognized as a major contributor of greenhouse gases to the atmosphere.

Economic crisis increases consumption of rice and beans in Brazil
The economic crisis is making the Brazilian consumer exchange meat for the traditional dish of rice and beans. High unemployment and falling incomes, together with the low prices of these products, caused by good harvest, are responsible for the increase in demand, which will be 15% to 20% this month, compared to the prediction for the year. The average consumption per capita is around 3, 5 kilos of rice and 1, 5 kilo of beans.

Um dado, comumente utilizado em jogos, cujos números nas faces são representados pela quantidade de pontos pretos é colocado frente a dois espelhos planos que formam entre si um ângulo de 60º. Nesses espelhos é possível observar nitidamente as imagens de apenas uma das faces do dado, sendo que a soma de todos os pontos pretos observados nos espelhos, referentes a essa face, totalizam 20 pontos. Portanto, a face voltada para os espelhos que gera as imagens nítidas é a do número ____.

The birds and the bees
My little boy came in the other day with a really serious look on his face and said, ‘Dad, do you mind if I ask you a question? Where do I come from?’ I’d been dreading this question for ages, but like a good father, I sat him down and gently told him all about the birds and the bees. When I’d finished, he was very quite. He then got up and went, ‘thank you, Dad’ and headed for the door. I said, ‘So what made you ask me?’ and he turned around and said, ‘I just want to know, because Bobby next door says HE comes from Manchester!’
