    I'm sure the beguile YOU, but did you listen to the Video I posted about some ACTUAL major problems ?
    No, I am sure not.

    Energy World Rocked as China Cuts Coal Imports, Aims for Fossil Fuel Car Ban | Robert Scribbler

    China is engaged in a major shift toward renewable energy production. Through July, China had added approximately 35 gigawatts of new solar electrical generation capacity — with 24 gigawatts of that capacity being added in June and July alone. Since July, China has closed approximately 150 smaller port facilities to coal imports. These ports, which China has designated as tier two, are less able to test coal for compliance with China’s new emissions standards. As a result, coal imports have re-routed to larger (tier 1) facilities. The closures have sent shivers through coal exporters like Australia as the line of ships waiting to off-load coal lengthened.

    And in September China announced they would set a deadline for car makers to stop selling vehicles that run exclusively on diesel and gasoline.

    A few years ago I remember some of the denialists on this forum arguing that the US shouldn't participate in any international AGW agreements, because, they said, China would NEVER agree to join those agreements. With the election of the Clown-In-Chief the tables have changed 180 degrees. What an embarrassment we've become...

    Worrying new research finds that the ocean is cutting through a key Antarctic ice shelf | Washington Post

    A new scientific study, published by the American Geophysical Union, has found that warm ocean water is carving an enormous channel into the underside of one of the key floating ice shelves of West Antarctica, the most vulnerable sector of the enormous ice continent. Ocean water is first flowing into the deep cavity beneath the Dotson Ice Shelf, but then being turned by the Earth’s rotation and streaming upward toward the floating ice as it mixes with buoyant meltwater. The result is that the warm water continually melts one part of the shelf in particular, creating the channel. The ultimate fear is that the undermining of the shelf will increase the flow of ice outward from the glaciers behind it.

    Good news, it will move out of the environment and not affect the USA.

    The Most Powerful Evidence Climate Scientists Have of Global Warming | Inside Climate News

    The rate at which the oceans are heating up has nearly doubled since 1992, and that heat is reaching ever deeper waters, according to a recent study. At the same time, concentrations of carbon dioxide in the atmosphere have been rising.

    Ocean temperatures have been rising about 0.12 degrees Celsius per decade on average over the past 50 years. The higher temperatures are driving marine life toward the poles in search of livable habitats, bleaching coral reefs, and causing severe impacts on fisheries and aquacultures. They also contribute to more frequent and intense extreme weather events.

    Taking the Pulse of the Planet| Earth and Space Science News (EOS)
    How fast is Earth warming? Ocean heat content and sea level rise measurements may provide a more reliable answer than atmospheric measurements.

    The most visible sign of a warming climate is the increase in air temperature, which affects the climate and weather patterns. However, atmospheric temperatures change a lot seasonally, and from year to year. Ocean temperatures, especially those in the ocean depths, change more slowly and are less effected by short-term temperature oscillations. Since 2006, the Argo program of autonomous profiling floats has provided near-global coverage of the upper 2,000 meters of the ocean over all seasons.

    Changes in Ocean Heat Content (OHC), global mean surface temperature (GMST),
    and sea level rise (SLR) during the past decade. All values are 2-month means;
    the dashed red lines indicate linear trends. The scale of the y axis is adjusted so that
    the linear trend has exactly the same slope for all three indices. El Niño events are marked
    as pale red bars, and the La Niña events are pale blue bars.
    All time series are referenced to a 2004–2015 mean.

    Massive Permafrost Thaw Documented in Canada, Portends Huge Carbon Release | Inside Climate News

    Huge slabs of Arctic permafrost in northwest Canada are slumping and disintegrating, sending large amounts of carbon-rich mud and silt into streams and rivers, according to researchers with the Northwest Territories Geological Survey. Similar large-scale landscape changes are evident across the Arctic including in Alaska, Siberia and Scandinavia, researchers write in a paper published in the journal Geology. Research by Swedish scientists suggests that the soil particles are quickly converted to heat-trapping CO2 when they are swept into the sea. Intensifying summer rainstorms in Canada have triggered huge landslides, damaging roads, power lines and water infrastructure, according to a recent evaluation of satellite images by Austrian climate researchers.

    Yeah, I'm pretty sure how this story plays out.

    India to Fight Airpocalypse by Making Every Car Electric by 2030 | Robert Scribbler

    In 2015 India surpassed China’s annual loss of life due to bad air. A large share of the pollution that causes these deaths comes from automobile emissions. India has now set a goal that 100 percent of all new cars sold by 2030 will be electrical vehicles. Much of the electricity needed will be met by wind and solar energy.

    And in other news, as the latest sign of the Trump administration's assault on climate science, Scott Pruitt of the EPA Abruptly Blocks 3 Agency Scientists From Giving Talks On Climate Change at a Narragansett Bay and Watershed workshop.
