Fundamental economics and the costs and benefits of addressing climate change

This post is a high-level summary of the central ideas underlying the evaluation of the economic costs and benefits of addressing climate change. One of the primary goals here is to explore, at a fundamental level, what is actually meant … Continue reading

Combining Physical and Statistical Models in Order to Narrow Uncertainty in Projected Global Warming

Below is a presentation I gave on our recent research published in Nature titled “Greater future global warming inferred from Earth’s recent energy budget”. This was for the Stanford University Department of Electrical Engineering and Computer Systems Colloquium (EE380). Thus, it is intended for … Continue reading

Global temperature: 2018 likely to be colder than 2017, record high possible in 2019

We are working on a new statistical method for predicting interannual variability in global mean surface air temperature (GMST). The method uses the preceding few years of globally gridded temperature anomalies and Partial Least Squares regression to predict the GMST of the following … Continue reading

AGU Talk on potential changes in temperature variability with warming

Below is my talk from the 2017 AGU fall meeting. This talk is on a paper we published in Nature Climate Change about potential changes in natural unforced variability of global mean surface air temperature (GMST) under global warming. Background Unforced … Continue reading

Greater future global warming (still) inferred from Earth’s recent energy budget

We recently published a paper in Nature in which we leveraged observations of the Earth’s radiative energy budget to statistically constrain 21st-century climate model projections of global warming. We found that observations of the Earth’s energy budget allow us to infer … Continue reading

Reducing greenhouse gas emissions helps the economy

Potential solutions to climate change are often framed as a tradeoff between reducing our impact on the environment and harming the economy. More specifically, it is thought that we can reduce our climate-change-related impact by reducing emissions of greenhouse gases … Continue reading

Can humanity maintain perpetual economic growth?

…to understand modern economic history, you really need to understand just a single word. The word is growth. –from Sapiens (2014) Humanity is far more materially wealthy today than any time in the past and our collective wealth continues to … Continue reading

Credibility through honesty about uncertainty

An argument that I often encounter is that uncertainties in climate science shouldn’t be publicly emphasized since that will make it harder to inspire action on proposed climate policies. It is thought that publicly highlighting a lack of knowledge/understanding on … Continue reading

Modeled vs. observed global temperature: with and without ‘makeup’

Global average surface air temperature is one of the most well-recognized metrics of contemporary climate change – hence the term ‘global warming’. One reason for this is that many impacts of climate change are expected to be proportional to the … Continue reading
