    For those with an interest in science ~ New report by the Union of Concerned Scientists:

    State of Charge: Electric Vehicles’ Global Warming Emissions and Fuel-Cost Savings Across the United States

    "Electric cars produce lower global warming emissions and cost significantly less to fuel than the average compact gasoline-powered vehicle."

    "The UCS report, State of Charge: Electric Vehicles' Global Warming Emissions and Fuel-Cost Savings Across the United States, compares the global warming emissions from EVs with those from gasoline-powered vehicles and finds that:

    *Nationwide, EVs charged from the electricity grid produce lower global warming emissions than the average compact gasoline-powered vehicle (with a fuel economy of 27 miles per gallon)—even when the electricity is produced primarily from coal in regions with the “dirtiest” electricity grids.

    *In regions with the “cleanest” electricity grids, EVs produce lower global warming emissions than even the most fuel-efficient hybrids.

    *EVs charged entirely from renewable sources like wind and solar power produce virtually no global warming emissions."

    "The report compares charging costs in 50 major cities across the United States and finds that:

    *On the best rate plans, electric vehicles can save $750 - $1,200 a year on fueling costs compared to a gasoline vehicle averaging 27 miles per gallon and fueled at $3.50 per gallon.

    *EV owners can save money on fueling costs without changing electricity plans, but taking advantage of rate plans that offer lower-cost electricity at night (“time-of-use” plans) can mean hundreds of dollars in additional savings per year, especially in California.

If you go back to when the planet was formed from colliding debris, current cosmology claims it was millions of years before the planet cooled enough to allow a permanent crust over the molten core, more millions of years until it cooled further to allow liquid water to form. Some argue (link) that there was no permanent ice cap until just a few million years ago (although he doesn't address the speculation of "snowball earth" that has been floated to explain what look like glaciation marks on some rocks in Australia). So, if you look at the long term, earth has been consistently - if not uniformly - cooling, not warming.

    In a shorter time frame, it's fairly safe to say the earth has been warming for the last twenty or thirty thousand years since the last ice age "ended." If you are worried about the ice caps melting and the ocean rising, forget it - that all happened 12,000 years ago (link).

    In a much shorter time frame, there is apparently another (milder) cycle of 10 or 12 centuries: Iceland was known to the Mediterranean world by around 300 BC, but then it got cold again and the island wasn't settled until around 900 AD. When the Norse settled Greenland a thousand years ago, they were able to supplement their hunting-fishing diet with vegetable gardens, but then the weather closed down for a couple of centuries and the settlements were gone by the time the Europeans were able to get back there. That "Little Ice Age" lasted for a few centuries (link) and it's end coincided closely with the beginning of our Industrial Age. The warm period should continue for another couple of centuries or so, but we are still not as warm as we apparently were a thousand years ago.

    On a really micro time frame, the best explanation I've seen for the current global warming hysteria (which replaced the "Coming Ice Age" hysteria of the seventies) is that after the Soviet Union collapsed in the early nineties, internal chaos caused the Siberian weather stations to stop reporting for a few years and this caused a very minor increase in the reported global average temperature.

    So let's drop the term "consistently" and discuss whether global warming is really such a bad thing. Global human population was around 200 million at the height of the RomaEmpire, reached one billion around 1800, two billion around 1920, and is now seven billion. Which 99% of the human race do you propose to eliminate in order to get back to your idea of Utopia?
    Okay....whatever you say:

    "All three major global surface temperature reconstructions show that Earth has warmed since 1880. 5 Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. 6 Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase."

    Here we go again, Obama doubling down on green energy...

    However, I wish the researchers good luck with this; I don't much care for spinach. First algae, now spinach to be green energy source.

    yeah..... you keep running with that theory, if you think that stability in the GSR is just around the corner.

    There's a thread around here where we discussed Iran. You should have dropped in on it.
