BBC: Environmentalists are taking issue with the International Energy Agency’s most recent report, Golden Rules for a Golden Age of Gas. In the report, the IEA promotes the development of the world’s vast resources of unconventional gas—shale gas, tight (trapped) gas, and coalbed methane—because increased natural gas use would displace the use of more carbon-intensive fuels, such as oil and coal. Only near the end of the report does the agency point out that such prolonged use of natural gas could lead to a global temperature rise of 3.5 °C, well above the widely accepted 2 °C target. Critics argue that because of global warming the IEA should not promote the use of any fossil fuel, whether lower-emission or otherwise, and that it should instead be promoting nuclear power and renewables like wind and solar.
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.
