The moon has its own carbon emissions, which changes our understanding of how it may have formed. Using data collected by Japan's Kaguya lunar orbiter over a year and a half, Shoichiro Yokota at Osaka University in Japan and his colleagues have discovered that the moon emits carbon ions across almost its entire surface. These plains are made of younger material, and as such emit more carbon because they have been exposed to space for a shorter period of time, says Yokota. Older regions have been exposed to more space weathering, and so have lost much of their carbon already. The researchers compared the moon's carbon emissions with estimates of the carbon supplied by two external sources – the solar wind, and collisions with micrometeoroids – and found they didn't match up.
Canada will impose a minimum price on carbon emissions, says the country's environment minister Catherine McKenna. The move is designed to push the nation's 10 provinces into properly regulating climate change-causing gases. Reuters reports that McKenna said so on CTV's Question Period, and that more details would be released before the end of October. Most of Canada's provinces are already working on carbon reduction plans, although there are some that are very resistant to carbon pricing. The newswire points out that Brad Wall, the right-wing premier of Saskatchewan is likely to be the target of McKenna's announcement.
OTTAWA – Canadian Prime Minister Justin Trudeau says Canada will implement a tax on carbon emissions by 2018 to combat climate change. Trudeau made the announcement in Parliament on Monday as debate started over whether Canada should ratify the Paris accord on climate change. It is expected to pass. Trudeau says provinces and territories can either put a direct tax on carbon emissions or adopt a cap-and-trade system. If they don't do so by 2018 the federal government will implement one.
Scientists at Oak Ridge National Laboratory have accidentally stumbled upon a way to capture carbon dioxide from the ambient air, creating prism-like crystals and combating global warming in the process. "When we left an aqueous solution of the guanidine open to air, beautiful prism-like crystals started to form," ORNL's Radu Custelcean said. "After analyzing their structure by X-ray diffraction, we were surprised to find the crystals contained carbonate, which forms when carbon dioxide from air reacts with water." In other words the solution could be used to grab CO2, which contributes to climate change, direct from the atmosphere and store it temporarily into crystals that form as a result. The researchers envision using the process as a way to boost the efficiency of existing carbon capture technology, which is a way of grabbing CO2 either from a source or the air and transporting it to be stored underground where it wont contribute to climate change.
WASHINGTON – After several years of little growth, global emissions of heat-trapping carbon dioxide experienced their largest jump in seven years, discouraging scientists. World carbon dioxide emissions are estimated to have risen 2.7 percent from 2017 to 2018, according to three studies released Wednesday from the Global Carbon Project, an international scientific collaboration of academics, governments and industry that tracks greenhouse gas emissions. The calculations, announced during negotiations to put the 2015 Paris climate accord into effect, puts some of the landmark agreement's goals nearly out of reach, scientists said. "This is terrible news," said Andrew Jones, co-director of Climate Interactive, which models greenhouse gas emissions and temperatures but was not part of the research. "Every year that we delay serious climate action, the Paris goals become difficult to meet."
