The Guardian: On 2 August the American Meteorological Society released its 26th annual State of the Climate report, which is compiled by the National Oceanic and Atmospheric Administration with input from hundreds of scientists around the world. The report indicates that 2015 saw record highs for atmospheric and oceanic temperatures, sea levels, and atmospheric carbon dioxide. The annual surface temperature increased 0.1 °C over 2014, and thus the global temperature is now 1 °C warmer than during preindustrial times. The eastern Pacific Ocean, which experienced further warming from El Niño, was 2 °C warmer than the long-term average, and the Arctic was 8 °C over its average. Oceanic warming contributed to a sea level that is about 70 mm higher than the average in 1993, when satellite measurements of sea levels began. The report also pointed to record lows for Arctic maximum sea-ice coverage and a net loss of alpine glacier ice for the 36th consecutive year.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
