A team of researchers has just completed a new investigation on how our planet would have looked like to a distant observer during the time of the dinosaurs. What this means is that the experts sought to figure out precisely how bright our world appeared to potential aliens on extrasolar planets.
Rather than use cl... |

In addition to causing harm to agriculture, changes in precipitation patterns over a certain region can also influence similar patterns around the world, even if indirectly. A new study reveals how airborne pollution is affecting rain clouds, causing such changes at different locations.
Moderate, dependable precipi... |

In recent days, so-called climate change skeptics have been quoting a study that they say shows man-made global warming is a farce. Scientists in the international community took a look at the study, and they widely agree that the work is filled with errors and misinterpretation of data. The idea on which the work is... |

A few years ago, atmospheric scientists discovered an peculiar phenomenon taking place as lightning strikes were headed to Earth – the generation of a flash of radiation accompanying the event. Now, the cause of these flashes is beginning to be revealed.Called gamma-ray flashes (GRF), these phenomena are charac... |

A satellite in Earth's orbit was able to snap a photo of an impressive atmospheric phenomenon, which experts can only see once per month, or even less often. The orbital instrument saw what is known as an undular bore, but is also called a gravity wave train. Such a formation can only develop in the planet'... |

For quite some time now, climate researchers have figured out that clouds play a critical role in determining the amount of sunlight that makes its way to Earth, and is retained here to warm the planet. A new study has just found that the amount of light that passes through depends on the photons' wavelength.Exp... |

After an extensive, 10-year-old review of data from NASA and other sources, a researchers was able to determine that clouds play an important role in global warming, in the sense that they amplify temperature rise generated by the release of carbon dioxide into the planet's atmosphere. The finding brings a new a... |

Until now, one of the largest mysteries associated with understanding how clouds form was how the atmospheric structures at times appear to form faster than the basic laws of physics allow for. Physicists now believe they may have uncovered the answer.The mechanism through which “usual” clouds form is fai... |

When most people see clouds, they only search for patterns, maybe in the shape of a dog, baby or building. But some experts look up in the sky and see a possible direction for our planet's future. As the world gets warmer, more and more water vapor will make its way into the atmosphere, which is a very dangerous... |

Cloud seeding is a means of controlling precipitations over a certain area. Basically, it refers to using various types of particles to elicit the formation of water droplets above areas that would otherwise suffer from drought. Generally, seeding clouds is very difficult, and can be achieved via two methods – ... |

Clouds are some of the most common features in nature. Almost every time you look at the sky, you see one of many types of clouds that form at various heights and have different behaviors. These atmospheric structures can be a sign of rain, or of incoming clear weather, and they can also be found on other planets, wh... |
