Today, I’m largely turning this blog over to Joseph Stiglitz, Nobel-prize winning economist who heads up economic research at the Roosevelt Foundation. Stiglitz recently testified before the Senate Budget Committee on what he–and President Biden–have both correctly termed an existential threat: climate change.
The following are excerpts from that testimony.The entire presentation is at the link.
Thank you for this opportunity to share with you some of my concerns about the large economic costs and huge risks of not taking strong actions now to deal with climate change, and the large benefits of doing so.
Some of the downside risks are already apparent. In one recent year, the magnitude of destruction associated with extreme weather events—which will inevitably occur more frequently, with ever more devastation as a result of climate change—was more than 1.5% of GDP, effectively wiping out more than 60% of the growth of that year.1 But this is only one dimension of what is occurring: Rising sea level will put much coastal property under water, destroying homes and property values. Forward-looking markets have already begun to price this in—but still far from adequately.2 3
Recent studies have documented the adverse effects of climate change on health.4 We pay for this in multiple ways, including higher health care costs and a less healthy population, which means a less productive workforce. But there is no way to accurately monetize the shorter life spans and the increased morbidity….
There are, of course, some sectors, some parts of our population, some locations that will be particularly hard hit. During the past year, we have seen the inequities associated with Covid-19. Those associated with climate change are equally severe, with people at the bottom of the income ladder often bearing the brunt of the costs, with fewer resources to respond. But there is an additional dimension of inequity that speaks to our future: While Covid-19 disproportionately affected older Americans, climate change is a risk that we impose on our children and grandchildren—on the future of our country….
Let me spend a few moments discussing the real risks our economy and society face if we do not take stronger actions than we have so far. We have been treating truly scarce resources, our environment, our water, our air, as if they were free. But economics teaches us that there is no such thing as a free lunch. We will have to pay the check someday. And delay is costly. Taking carbon out of the atmosphere is far more expensive than not putting it into the atmosphere. A smooth transition is far less costly than the one we will surely face if we do not take action urgently….
The longer we delay dealing with climate change, the larger the necessary adjustments will be, and the greater the potential for huge economic disruption—an economic disruption that could make the 2008 Great Recession look like child’s play by comparison.6 The danger of a crash is particularly acute for the U.S. economy, given that large U.S. banks are the largest financiers of fossil fuel….
Economics has, for good reason, been called the dismal science. The scenario of doom and gloom that I have painted is, unfortunately, all too real. But I want to end on a sunnier note. Doing something about climate change could be a real boon for the economy.
Too often, critics of taking action point to the job losses. Change is costly. But change provides opportunity. I am also firmly convinced that the opportunities afforded by addressing climate change are enormous. The number of jobs that will be lost in the old fossil fuel industries are dwarfed by those that will be created in the new industries. The value created in the new industries will also dwarf the value of the stranded assets in the fossil fuel and related sectors. As just two examples: the number of installers of solar panels already is a multiple of the number of coal miners; the auto company with the highest valuation today is Tesla…
The current focus on changing to a green economy is already stimulating enormous innovation, innovation that holds out the promise of significant increases in standards of living. The price of renewable energy has been plummeting, and in many areas outcompetes fossil fuels. The drive for a greener society is stimulating the design of new buildings and new ways of doing agriculture, which turn out actually to save resources, particularly if we value them appropriately….
Our country especially has much to gain, because innovation is a key comparative advantage. If we are ahead of the game—rather than a laggard—we will develop technology that will be in demand around the world. If we are behind the game, we will pay a high price. It is almost inevitable that other countries will demand cross-border adjustments that will put our companies at a disadvantage….
There is much more to be done to protect the economy from the risks I have described. For instance, we need immediately to end fossil fuel subsidies and require full disclosure of climate risks—both the risks of physical damage and the financial risks. Markets on their own don’t provide adequate disclosure, necessary both for the efficient allocation of scarce capital and for protecting investors. We need to change statutes governing fiduciary responsibility to mandate looking at these long-run risks, and especially where government is at risk, as in government insurance pension schemes…
There’s much more at the link, and it is definitely worth reading in its entirety.
