The fundamental (and somewhat existential) source of climate change – and how we might overcome it

With the news that this past July was the hottest month on earth since record keeping 140 years ago, satellite images of the Amazon and State of California burning, the most powerful hurricane ever measured in the Atlantic Ocean east of Florida, carbon dioxide emissions to the atmosphere rising again to near record levels after a brief leveling, and Swedish teenager Greta Thunberg’s stirring call to action while staring down both Donald Trump and Vladimir Putin, climate change has been a hot topic in 2019. While the scientific community remains nearly 100% aligned that global warming is driven by the burning of fossil fuels, a relatively small, yet powerful, group of naysayers fights the science. Who are these very powerful people, and why do they fight? One common characteristic – they are mostly baby boomers = the generation of Americans with an insatiable appetite for consumption and a strong resistance to change.

Don’t get too worked up over the President’s actions against the environment

Every week seems to bring another attack by the Trump Administration against laws and regulations that have been instituted by prior administrations to protect the environment and fight climate change. The most recent is the campaign to deny California the right to set stricter automobile emissions standards than federal limits. It has caused yet another uproar among environmentalists and liberals and glee among climate change deniers and conservatives and will undoubtedly lead to many years of legal battles. But what is reality? In fact, this move, and all the others, are just meaningless actions that do little more than pander to the Administration’s fossil fuel campaign contributors and excite the hardcore Republican base ahead of the upcoming elections. The reality is that technology and market forces are driving the world inexorably and at an increasing pace toward a renewable energy future, despite the last-ditch efforts of the President and his supporters. Let’s look at some of the higher profile actions.

Do Renewable Portfolio Standards Increase Electricity Rates?

I live in California. That gives me a front seat to virtually every new initiative and trend related to saving the planet, whether it is about turtles and plastic straws, banning single-use plastic bags, electric vehicles, or green energy. Although not the first state to adopt a Renewable Portfolio Standard (RPS), California has been one of the most aggressive in its timetable for replacing fossil fuel based electricity with carbon-free. In 2018, California updated its RPS to the requirement to achieve 60% of electricity sales from renewable sources by 2030 and 100% by 2045. Of course, California’s aggressive push toward renewables has triggered a wide range of reactions. For example, Michael Shellenberger of Environmental Progress has been pushing the idea that California’s electricity rates are significantly higher than the rest of the US (see Figure 1) and rising significantly faster because of its dependence on renewables. His culprit is renewable energy and his solution is to keep nuclear plants open. In contrast, Roger Sowell, who blogs about renewable energy issues, argues that California’s unique climate, geography, and large population make such differences to be expected.
