carbon dioxide

Even if we achieve the carbon emissions reductions that the Paris Agreement calls for, there is the risk of the planet entering “hothouse Earth” conditions. A “hothouse Earth” climate will in the long term stabilize at a global average of 4-5°C higher than pre-industrial temperatures with sea level 10-60 mContinue Reading

  A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could potentially hold more water than Earth. The planets’ densities, now known much more precisely than before, suggest that some of them could have upContinue Reading

Researchers have found a new recipe for providing evidence that a distant planet harbors life, one that might be more promising than just looking for oxygen. “…our suggestion is doable, and may lead to the historic discovery of an extraterrestrial biosphere in the not-too-distant future…” “This idea of looking forContinue Reading

Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps). The research article was published today inContinue Reading
