More bad news on climate change from the United Nations
The Earth is locked on an â€œirreversibleâ€ course of climatic disruption from the buildup of greenhouse gases in the atmosphere, and the impacts will only worsen unless nations agree to dramatic cuts in pollution, an international panel of climate scientists warned Sunday.
The planet faces a future of extreme weather, rising sea levels and melting polar ice from soaring levels of carbon dioxide and other gases, the U.N. panel said. Only an unprecedented global effort to slash emissions within a relatively short time period will prevent temperatures from crossing a threshold that scientists say could trigger far more dangerous disruptions, the panel warned.
â€œContinued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts,â€ concluded the report by the United Nationsâ€™ Intergovernmental Panel on Climate Change (IPCC), which draws on contributions from thousands of scientists from around the world.
The report said some impacts of climate change will â€œcontinue for centuries,â€ even if all emissions from fossil-fuel burning were to stop. The question facing governments is whether they can act to slow warming to a pace at which humans and natural ecosystems can adapt, or risk â€œabrupt and irreversible changesâ€ as the atmosphere and oceans absorb ever-greater amounts of thermal energy within a blanket of heat-trapping gases, according to scientists who contributed to the report.
Meanwhile in Canada, we donâ€™t care about climate change, only our own economy.
Canada’s hopes of securing an outlet for its landlocked oil wealth and pulling an end run around the eternally deadlocked Keystone XL project took a big step forward Thursday with the release of formal plans to build a U.S. $11 billion pipeline to the Atlantic.
TransCanada, the biggest Canadian pipeline company, submitted its application to Canadian energy regulators for a nearly 3,000-mile-long, million-barrel-a-day pipe running from oil-rich western Canada to refineries and shipping terminals in the east. The so-called Energy East Pipeline Project, which TransCanada officials hope could be in operation as soon as 2018, would provide an export outlet for huge volumes of current and future oil production that right now has no easy way to get to market.
The project wouldn’t replace the Keystone XL pipeline — Canada’s other high-profile, multibillion-dollar oil-transport project, which has been awaiting U.S. approval for years — but it could give Republican critics of U.S. President Barack Obama’s administration fresh fodder ahead of the midterm elections. Republicans have long argued that the White House’s refusal to sign off on the Keystone project would cost the United States tens of thousands of jobs. The Obama administration has finished reviewing the environmental merits of Keystone, but pushed back any decision until later this year or early 2015.
If the new Canadian route gets approved in 2016 by Canada’s National Energy Board, as TransCanada expects, it would give the eastern provinces a source of domestic oil — removing the need for some 700,000 barrels a day of oil imports — and would give producers in Alberta and Saskatchewan a direct route to big refineries that could turn the sludgy tar sands into valuable products such as diesel, gasoline, and jet fuel.
Over in Germany
On any given day, Johannes van Bergen, director of the municipal utility Stadtwerke SchwÃ¤bisch Hall in southwestern Germany, conducts his team’s array of gas, heat, and electricity sources to meet the energy needs of at least several hundred thousand Swabians in the region, as well as about more than 90,000 customers elsewhere in Germany. And every day — in fact, every hour — that energy mix is constantly in flux.
Technicians at the town’s smart-grid center monitor and manage the utility’s roughly 3,000 regional energy suppliers: several thousand solar photovoltaic (PV) installations, two wind parks, one gas-and-steam power station, six small hydro-electric works, three biomass (wood pellet), sixbiogas plants, and 48 combined heat and power plants, as well as other conventional and renewable energy suppliers outside the municipality.
The population that this ballet of coordinated energy sources serves is admittedly modest, but it’s here that the future of Germany’s energy industry is being tested in full — and proven.
Which of course is a model that we could use here but for whatever reason, the province and the country isnâ€™t willing to experiment.
Their output, and increasingly that of the conventional, too, is distributed through a tightly knit, cross-border smart grid. The composition of supply changes from minute to minute depending on weather, demand, and other factors from one corner of the country to the other. Increasingly electricity is generated in and traded from locality to locality, and even across the country (or countries) via intelligent networks much like that in SchwÃ¤bisch Hall and other places in Germany.
No one predicted this scale of locally driven, citizen-led energy boom when the Energiewende began. Even just four years ago, just about everybody involved in the Energiewende thought that big-ticket projects like enormous offshore wind farms planned for Germany’s northern seas and Desertec, the mega-project to import solar energy across the Mediterranean from sprawling concentrated solar power arrays in the Middle East and Northern Africa, would be integral to Germany going renewable.
These projects, however, have flopped spectacularly.
Offshore wind has proven extremely pricey and technologically much trickier than originally assumed, which has led to billons in cost overruns and years-long delays. Germany’s seven operational offshore parks constitute a tiny fraction — just 0.6 percent — of the country’s renewably generated electricity, compared to onshore wind’s 34 percent. The offshore industry claims there’s smooth sailing for offshore wind just around the corner, but it’s been saying that for years.
