What’s the difference between bad (Trumpian) energy policy and good (clean energy based) energy policy? For Los Angeles and San Diego which both experienced an extreme, climate change driven, heatwave over the past week, about 4 degrees Fahrenheit.

In other words, fossil fuel burning under Trump policies would be of much greater magnitude and extend for far longer into the future. This would pump more heat trapping carbon into the atmosphere and ratchet global temperatures much higher.

According to a recent science-based article from Joe Romm at Think Progress, what it means is that the 110 to 120 degree (F) heatwaves of today, under Trumpian policy, will turn into the 131 degree heatwaves of tomorrow.

In other words, it’s not a question of whether climate change will worsen. It will, at least for a while. It’s a question of how bad things will…
