In this third episode of our mini-series on climate science, we talk with paleoclimate scientist Robert Kopp of Rutgers University about what Earth’s past climate can tell us about its future, especially where it concerns sea level rise. We also discuss his research on the relationship between climate science and the economy, and how a transdisciplinary approach using natural sciences, social sciences, engineering, and urban planning can help us tackle the challenges that climate change poses to the world’s coastlines…and how tools like the social cost of carbon and appropriate discount rates can help address those challenges, from New Jersey to Florida, no matter what Trump does with federal policy. Finally, we discuss how ratings agencies and risk adjustors need to start factoring in climate risk, and why they haven't so far.
In this second episode of our mini-series on climate science, we begin to dive a bit deeper on narrower subjects, starting with a look at how we take the Earth’s temperature, on land, on the sea surface, and deeper in the ocean depths. Along the way, we discuss temperature measurements at the heart of the “Climategate” nothingburger, the 2013 “Pausebuster” paper proving the supposed “pause” or “hiatus” in global warming trends didn’t actually happen, and a recent kerfuffle over that paper. We also find out if the melting of permafrost and undersea methane clathrates could lead the planet into runaway global warming, and discuss some research on the net emissions effect of switching from coal to gas in power generation, including the thorny issue of fugitive emissions from natural gas production and distribution. And finally, we’ll take another look at the question of decoupling economic growth from energy consumption, and how emissions are counted in the first place. After listening to this interview, you’ll be well-equipped to listen critically to both the latest scientific findings on global temperatures, and to the arguments of global warming skeptics. Plus, we’ll talk about the implications of Trump’s proposed budget, which would gut the very agencies that deliver these crucial scientific measurements.
With President Trump fully embracing fossil fuels and indicating that he intends to abandon US efforts to address climate change (and even the scientific inquiry underlying those efforts), there is no time like the present to refresh what we know about climate change, what we can do about it, and what kinds of research still need to be done to improve our understanding. This episode is the first of what will become a mini-series of episodes on the science of climate change, and it starts by looking at the debate over climate change, the counter-arguments of climate change skeptics and the rebuttals to those arguments, and what recent scientific observations can tell us. It also suggests that ultimately, there may be a lot more willingness amongst the rank and file of all political parties to take action on climate, regardless of ideological perspectives on the left and right.
