Minneapolis's citizen-centric approach to climate action. With average winter temperatures of just over 15 degrees Fahrenheit, you might think Minneapolis could use a little warming.
But even this metropolis is feeling the effects of a changing climate — primarily in the form of increased flooding and extreme heat and humidity. In July, the National Weather Service issued an excessive heat warning for much of Minnesota, with temperatures forecasted to reach anywhere from 105 to 110 degrees. While the city historically has had hot and muggy summers, there is an unmistakable upward swing toward more frequent and higher extremes. "We know that our temperatures are rising; we’re going to be experiencing more hot days but also more extreme humidity days, which tend to be a major driver of our extreme heat events," Kelly Muellman, sustainability program coordinator at the city of Minneapolis, told GreenBiz. Meanwhile, Minnesota has been battered by a significant uptick in severe flooding.
Mixed progress on mitigation. Our best shot at cooling the planet might be right under our feet. It’s getting hot out there.
Every one of the past 14 months has broken the global temperature record. Ice cover in the Arctic sea just hit a new low, at 525,000 square miles less than normal. And apparently we’re not doing much to stop it: according to Professor Kevin Anderson, one of Britain’s leading climate scientists, we’ve already blown our chances of keeping global warming below the “safe” threshold of 1.5 degrees. If we want to stay below the upper ceiling of 2 degrees, though, we still have a shot. But it’s going to take a monumental effort. Meet John D. Liu, the Indiana Jones of Landscape Restoration. [ English | Español ] Author: Alexandra Groome He’s known to some as the “Indiana Jones” of landscape degradation and restoration.
John D. Liu, ecosystem restoration researcher, educator and filmmaker, has dedicated his life to sharing real-world examples of once-degraded landscapes newly restored to their original fertile and biodiverse beauty. Liu is director of the Environmental Education Media Project (EEMP), ecosystem ambassador for the Commonland Foundation and a visiting research fellow at the Netherlands Institute of Ecology of the Royal Netherlands Academy of Arts and Sciences. We recently sat down with Liu, the newest member of the Regeneration International (RI) Steering Committee. In order to survive as a species, Liu explains, humanity must shift from commodifying nature to ‘naturalizing’ our economy. Interview with John D. Liu: There is now recognition of soil carbon, which was not the case in the past. The Ozone Hole Is Finally Healing.
Explicit cookie consent. THIS year the world’s power stations, farms, cars and the like will generate the equivalent of nearly 37 billion tonnes of waste carbon dioxide.
All of it will be dumped into the atmosphere, where it will trap infra-red radiation and warm the planet. Earth is already about 0.85°C warmer than last century’s average temperature. Thanks to the combined influence of greenhouse-gas emissions and El Niño, a heat-releasing oceanic phenomenon, 2016 looks set to be the warmest year on record, and by a long way.
It would be better, then, to find some method of disposing of CO2. One idea, carbon capture and storage (CCS), involves collecting the gas from power stations and factories and burying it underground where it can do no harm. A paper just published in Science offers a possible solution. Dr Matter’s project, called CarbFix, is based in Iceland, a country well-endowed with both environmentalism and basalt. They followed this success by burying unscrubbed exhaust gas. Iceland Carbon Dioxide Storage Project Locks Away Gas, and Fast. Photo For years, scientists and others concerned about have been talking about the need for carbon capture and sequestration.
That is the term for removing carbon dioxide from, say, a coal-burning power plant’s smokestack and pumping it deep underground to keep it out of the atmosphere, where it would otherwise contribute to global warming. C.C.S., as the process is known, has had a spotty record so far. While there are some projects being designed or under construction, only one power plant, in Canada, currently captures and stores carbon on a commercial scale (and it has been having problems). Keeping a lot of CO2 out of the atmosphere would require a costly expansion of the technology to many more power plants and other industrial facilities. Among the concerns about sequestration is that carbon dioxide in gaseous or liquid form that is pumped underground might escape back to the atmosphere. One key to the approach is to find the right kind of rocks. Video Continue reading the main story. Coming Soon: Carbon Capture Plants That Suck CO2 Out Of The Air.
