  •  We can keep procrastinating (17+ / 0-)

    but we damn well should not. Even though a majority of Americans acknowledges that climate change is real and we should take action, the politicians are determined to do the wrong thing. For example, 53 Senators (including some Democrats) just signed a letter demanding the president approve the Keystone XL pipeline. I cannot think of a single Republican in the House or Senate that is not a climate change denier. The disinformation machines in conservative media are still cranking full steam. Fossil fuels industries are piling up  record profits year after year and projecting more in the coming decades. Pretty sad.

    Be radical in your compassion.

    •  We Have Taken Action (7+ / 0-)

      Thanks to Dem-inspired policies, US per/capita emissions are down 5% since 1990.  Aggregate US emissions are up by about 5% during that time period.

      More recently, thanks to the EPA, many coal-fired power plants are being replaced by ones that use natural gas.

      If you had told someone in 1990 that the average US citizen would be using less CO2 in twenty years, no one would have believed you.

        the economy. That has driven down emissions more than anything.

          no ...

          * Industrial/business activity fell.
          * Cheap natural gas radically driving down coal use in US electricity
          * Increasing renewables helping drive down coal in US electricity
          * Improving gas mileage of fleet

          Decrease in miles driven is only part of the equation.

            pollution.

            Actually, yes.

            •  Sigh ... (0+ / 0-)

              Again, it is only part of the equation.

              The agency attributed the decline to a combination of three factors: a mild winter, reduced demand for gasoline and, most significant, a drop in coal-fired electricity generation because of historically low natural gas prices. Whether emissions will continue to drop or begin to rise again, however, remains to be seen, experts said Friday.

              •  Natural gas is cleaner than coal at the burning (0+ / 0-)

                stage. 50% cleaner. But then

                Climate Benefits of Natural Gas May Be Overstated

                Advocates for natural gas routinely assert that it produces 50 percent less greenhouse gases than coal and is a significant step toward a greener energy future. But those assumptions are based on emissions from the tailpipe or smokestack and don’t account for the methane and other pollution emitted when gas is extracted and piped to power plants and other customers.

                The EPA’s new analysis doubles its previous estimates for the amount of methane gas that leaks from loose pipe fittings and is vented from gas wells, drastically changing the picture of the nation’s emissions that the agency painted as recently as April. Calculations for some gas-field emissions jumped by several hundred percent. Methane levels from the hydraulic fracturing of shale gas were 9,000 times higher than previously reported.

                When all these emissions are counted, gas may be as little as 25 percent cleaner than coal, or perhaps even less.

                I notice you dropped the CAFE standards since they have not kicked in yet.

                Don't get me wrong, I would be happy if emissions were reduced due to environmental policy but it's the economy and as you note the weather that are the biggest factors influencing emissions.

                  I was simply doing a cut and paste.

                  Second, the new car mpg is significantly higher than five years ago.  It is already starting to have an impact.

                  And, yes, I am quite aware of the issues around natural gas and the uncertainty as to methane leakage rates.

                  Again, however, car mileage due to economic conditions is not the only or even the largest factor.

        Don't worry, be happy ...

        Do you think that we are doing anything approaching near enough?

        Do you think that "Dem-inspired" is anywhere near aggressive enough?

        Oh, that's right, climate change is an issue that can wait until we've dealt with other issues.

        And, have you written a letter to Virginia's politicians endorsing an end to the gas tax?
