Eight years ago, I posted some words here about whether climate change was as serious as it was being made out to be, and whether the evidence that global warming was being caused primarily by man-made CO2 and other greenhouse gasses was as solid as climate advocates had asserted. Today, given the evolving weather trends over the past decade or so, I tend to be more sympathetic to the view that climate change is real, and I generally agree that the trend is towards higher temperatures
(both air temps and sea temps) and more instability in established weather patterns.
Personally, I don’t think that emission reduction or green energy strategies are going to do much to stem the change, at least not in the next few years or even decades. In the longer term, technology will make our industrial and transport infrastructure more efficient and less dependent upon carbon-based fuels. “Renewables” (aka “green energy” sources such as wind and solar generators) along with nuclear power now meet about 21% of global energy demand. This will get close to 25% by 2020.
Renewables and nuclear might hit 50-50 parity with carbon-based fossil fuels by around 2070, according to some optimistic projections; these scenarios assume that carbon-based fuel use starts declining by 2020. However, a 2016 US Energy Information Agency projection (made during the Obama Administration) indicates that carbon fuel usage will continue to grow thru 2040. In the EIA scenario, renewables and nuclear account for » continue reading …
