  • 1997 was ‘tipping point’ for ice caps around Greenland’s edges

    Measuring almost 100,000 km2 (about twice the size of the Netherlands), the ice caps around Greenland’s edges represent the largest glacierised area on earth, outside of the large ice sheets of Greenland and Antarctica. On a healthy ice cap, tens of metres of tightly packed snow are able to absorb meltwater in summer. In winter, that water refreezes, causing the total mass to remain more or less stable from year to year. However, increasing temperatures have knocked that yearly cycle out of balance. The amount of meltwater is so great that the tightly packed snow is now completely saturated with refrozen meltwater. That means that new meltwater cannot be absorbed by the snow anymore, causing it to run off into the sea.

  • Climate breaks multiple records in 2016, with global impacts from the World Meteorological Society:

    “This report confirms that the year 2016 was the warmest on record – a remarkable 1.1 °C above the pre-industrial period, which is 0.06 °C above the previous record set in 2015. This increase in global temperature is consistent with other changes occurring in the climate system,” said WMO Secretary-General Petteri Taalas.

    […]

    At least three times so far this winter, the Arctic has witnessed the Polar equivalent of a heatwave, with powerful Atlantic storms driving an influx of warm, moist air. This meant that at the height of the Arctic winter and the sea ice refreezing period, there were days which were actually close to melting point. Antarctic sea ice has also been at a record low, in contrast to the trend in recent years.

  • Study: Emissions from power plants, refineries may be far higher than reported

    A new peer-reviewed paper in Environmental Science and Technology suggests that methane emissions from natural gas power plants and oil refineries may be significantly higher than accounted for in current inventories. The report estimates average hourly methane emissions 11 to 90 times higher for refineries, and 21 to 120 times higher for natural gas power plants than those calculated from data provided by facility operators to Environmental Protection Agency’s Greenhouse Gas Reporting Program.

    By multiplying total CO2 emitted annually by all US natural gas power plants and refineries (as tallied by EPA) by the methane-to-CO2 emission ratio determined in the study, the authors estimate yearly methane emissions from the nation’s refineries and gas-fired power plants are twenty times higher than currently reported.

      • worldicelossn1058px_0How Much Arctic Sea Ice Is Each of Us Melting? Quite a Bit, New Study Says

        The study’s authors, climate scientists Dirk Notz and Julienne Stroeve, applied this finding to per capita emissions data from 2013 for each country, and found that the average person causes the loss of hundreds of feet of sea ice each year. But the U.S. and other high-emitting countries like Australia, Saudi Arabia and the United Arab Emirates are not average. Americans, for instance, have a personal footprint of as much as 645 square feet of ice loss. China, a large emitter but with a massive population, has lower per-capita emissions, with up to 322 square feet of ice loss per person.

        Climate policy making is based on the twin propositions that two degrees Celsius (2°C) of global warming is an appropriate policy target, and that there is a significant carbon budget and amount of “burnable carbon” allowable whilst meeting this target. This survey concludes that the evidence does not support either of these propositions.The catastrophic and irreversible consequences of 2°C of warming demand a strong risk-management approach, with a low rate of failure. We should not take risks with the climate that we would not take, for example, with civil infrastructure.

        Climate as a common good
        23. The climate is a common good, belonging to all and meant for all. At the global level, it is a complex system linked to many of the essential conditions for human life. A very solid scientific consensus indicates that we are presently witnessing a disturbing warming of the climatic system. In recent decades this warming has been accompanied by a constant rise in the sea level and, it would appear, by an increase of extreme weather events, even if a scientifically determinable cause cannot be assigned to each particular phenomenon. Humanity is called to recognize the need for changes of lifestyle, production and consumption, in order to combat this warming or at least the human causes which produce or aggravate it.

      • Global shale gas development

        Extracting oil or natural gas from shale poses a number of risks to the environment and requires large quantities of nearby water. Much of this water is needed for fracturing the shale to allow hydrocarbons to flow to the surface. Yet shale resources are not always located where water is abundant. Our analysis shows that China, India, South Africa, and Mexico, for example, have large quantities of shale gas but limited supplies of freshwater. It also shows that roughly 38 percent of the area where shale resources are located is arid or under significant water stress; plus, 386 million people live above these areas. These factors pose significant social, environmental, and financial challenges to accessing water and could limit shale development.

As this unconventional extraction method (collectively known as “fracking”) has pushed into more densely populated a reas of the United States , and as fracking operations have increased in frequency and intensity, a significant body of evidence has emerged to demonstrate that these activities are inherently dangerous to people and their communities.

      • Rejection of Colorado Coal Mine on Global Warming Grounds Could Be Game-Changer

        A U.S. District Court judge ruled on June 27 that the Bureau of Land Management (BLM) and Forest Service both wrongly approved expansion of the West Elk coal mine in Somerset, Colo., because they failed to take into account the economic impacts greenhouse gas emissions from the mining would have.

        The federal agencies said it was impossible to quantify such impacts, but the court pointed out a tool is available to quantify the effects of emissions and the agencies chose to ignore it. The tool, the “social cost of carbon protocol,” puts a price on the damages from drought, flood, storm, fire and disease caused by global warming

        “There’s a profound game-changing event going on in the life of the sea,” says Callum Roberts, a professor of marine conservation at the University of York, England. “The fact is that changes in alkalinity are going to cause massive reorganization of marine life, impacts on marine food webs, productivity, all sorts of things. We’re heading for a car crash here.”

        Many of these risks are caused by one of the world’s most pressing problems: climate change. Rising greenhouse gases in the atmosphere are causing global temperatures to rise, which is leading to the melting of the polar ice caps, which in turn has resulted in rising sea levels and a host of ecological issues.

Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with recent advances in understanding of the climate system, some potential abrupt changes once thought to be imminent threats are now considered unlikely to occur this century.

        A target of limiting warming to 2°C has been widely adopted, as discussed above. We suspect, however, that this may be a case of inching toward a better answer. If our suspicion is correct, then that gradual approach is itself very dangerous, because of the climate system’s inertia. It will become exceedingly difficult to keep warming below a target smaller than 2°C, if high emissions continue much longer.
