The Risky Business Report, a bipartisan project backed by three former U.S. Treasury Secretaries as well as other political and business leaders that seeks to quantify and publicize the economic risks from the impacts of a changing climate, calls for new policies to “reduce the odds of catastrophic outcomes” from extreme heat and rising sea levels linked to climate change. Such severe impacts will likely cost billions of dollars in annual property loss, threaten human health. lower labor productivity and endanger the nation’s electricity grids, according to the report The findings summarized by the report also show that the most severe risks can still be avoided through early investments in resilience and through immediate action to reduce the pollution that causes global warming.
“I know a lot about financial risks — in fact, I spent nearly my whole career managing risks and dealing with financial crisis,” former treasury secretary (under George W. Bush) Henry M. Paulson Jr. says in the report. “Today I see another type of crisis looming: a climate crisis. And while not financial in nature, it threatens our economy just the same.” Continue reading →
The CNA Corporation Military Advisory Board, a leading government-funded military research organization, issued a major report this week finding that the accelerating rate of climate change poses a severe risk to national security and acts as a catalyst for global political conflict. Among its findings, the report predicts that an increase in catastrophic weather events around the world will increase the demand for American troops, even as flooding and extreme weather events at home could damage naval ports and military bases. In the latter category is the extreme weather we’re suffering right now here in San Diego — 100 degrees, 5 percent humidity and winds gusting to 50 miles per hour — that is exacerbating the wildfires that can so plague us and is damaging thousands of acres on one of the U.S. military’s largest bases. The picture below is of the San Marcos Fire (one of nearly a dozen burning in San Diego now) taken from my front yard using my phone.
It’s remarkable to me the way so many denialists are willing and seemingly eager to reject science, even to the extent of putting our national security at risk, but don’t reject the benefits of modern science, such as technology and medicine. Those who want to deny science, if they are going to be consistent, need to throw away their cell phones and their prescriptions.
On Monday, the United Nations’ Intergovernmental Panel on Climate Change issued an important report on climate change. From the report: “Impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.” Moreover, for “countries at all levels of development, these impacts are consistent with a significant lack of preparedness for current climate variability in some sectors.” In other words, climate change is a big problem and we’re ignoring it. That’s important stuff, if not exactly news.
Global climate change is always a hotly debated subject (pardon the pun). The broad and deep consensus of scientists is clear that the change is real, man-made and dangerous. A few critics — largely funded by industries that would be most impacted by the policy changes required to deal effectively with climate change — disagree. My view is clear. That said, I readily acknowledge that, while it seems unlikely, the scientific community might be wrong. However, because the magnitude of the stakes are so enormous, it seems obvious to me that we ought to take serious steps to try to mitigate the problem even if the likelihood of error is high. Simply put, if I think that there is even a 10 percent chance that my car would blow up while driving home tonight, I’m not driving the car home.
On the other hand, some activists trying to stop climate change remain wildly unrealistic. It isn’t likely that many of us will be anxious dramatically to change our standards of living for a nebulous and seemingly far-off consequence. In my view, the most promising possibility for dealing with climate change is technological advance that makes carbon emissions obsolete.
The current issue of The New Yorkerexamines, in great depth, the challenges, difficulties, prospects and frustrations of the International Thermonuclear Experimental Reactor project, a 35-nation effort that is perhaps our best opportunity to “change the game” technologically. I encourage you to read it. A taste follows.
With an Apollo-like commitment, Janeschitz told me, fusion’s remaining problems could be worked out within a lifetime. But the funding would need to come in significant amounts, and mostly at once, not dribbled over decades. As he sketched out his vision, he alluded to an aphorism by an early Soviet tokamak pioneer, a quote that practically echoes among the halls of ITER’s headquarters: “Fusion will be ready when society needs it.”
Barry Ritholtz has a terrific piece up today on dealing with climate change.
This debate is no longer about whether global warming is real (it is) or whether humans are the most likely cause (you are), but rather, some very interesting and different questions that might be more professionally relevant to finance: How is this going to affect business? What are the investing consequences? Who will be the financial winners and losers of climate change?
You should read it and read it in conjunction with my post from just over a year ago — Hot Action Item. Make it a climate change twofer.
Hans Rosling has a real gift for explaining data and what it means. In the following short video, Rosling uses Legos to explain population growth, global health/wealth inequality and the carbon footprint.
Five years ago my family and I were awakened early in the morning and forced to evacuate our home due to raging wildfires burning out of control near our home in Southern California and fanned by winds gusting to over 100 miles per hour (as shown right). Unlike many of our neighbors, we had time to gather a few things before we escaped. We left seriously doubting that we would return to find our home still standing.
After nearly a week we were allowed back into our neighborhood. Fortunately, our home survived. We suffered smoke damage and some damage to trees, but few other problems of note. Many of our friends and neighbors were not nearly so lucky (see below). Just within our church community, 70 families lost their homes. We live with “fire season” every year. But the problems and the risks have grown consistently over the 17 years we have lived in San Diego and they will continue to grow, largely on account of climate change.
According to nearly all working scientists in the field and the various organizations representing America’s best scientists, climate change is a fact. It is very likely caused by the emission of greenhouse gases from human activities and poses significant risks for a range of human and natural systems. As these emissions continue to increase, further change and greater risks will ensue. These risks include rising temperatures, extreme weather, and the problems caused or (more typically) exacerbated by them. A helpful summary of the science of climate change is provided by the following video.
Without belaboring what is remarkably clear, temperatures are rising significantly.
If you don’t want to believe scientists directly, then believe the highly profit-motivated insurance industry, which has become the first major business sector to acknowledge the effects of climate change and to seek to deal with that risk in a systematic fashion. Just two weeks before Sandy slammed onto the Jersey shore, German reinsurance giant Munich Re issued a report entitled Severe Weather in North America, in which it linked the risks of severe weather events to human-caused, or anthropogenic, climate change: “In the long-term, anthropogenic climate change is believed to be a significant loss driver. […] It particularly affects formation of heatwaves, droughts, thunderstorms and — in the long run — tropical cyclone intensity.” Allianz actively lobbies for worldwide, binding carbon emission targets and has designed various insurance products to deal with climate change risk, such as catastrophe bonds and micro-insurance. Swiss Re also has a product line that is explicitly geared toward climate-change risks.
There is a dedicated group of climate change “skeptics” who insist either that climate change is a myth or that its risks are overstated. Since causation is such a difficult matter to ascertain to everyone’s satisfaction (and especially to the asserted satisfaction of those whose financial status is threatened by climate change), there will be some kind of debate about this for the foreseeable future. But no serious climate scientist believes that sea level will rise less than a meter this century unless we get off fossil fuels with great haste. Many forecasts are much grimmer. At least 20 port cities will be seriously exposed to coastal flooding risks in the coming decades including Mumbai, Calcutta, Ho Chi Minh City, Shanghai, Bangkok, Tokyo, Miami, Alexandria, and New York (as Hurricane Sandy demonstrated).
But even if the science were in dispute, when an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established. In this context the proponent of a threatening activity, rather than the public, should bear the burden of persuasion. If they cannot do so — by establishing that climate change is not a substantive risk — then we should act as if climate change is a major risk to our lives and health. This approach is particularly appropriate, as Nassim Taleb points out, because the extent of the threat and the risks are so high. As Taleb explains, we should readily use a headache pill if it is deemed effective at a 95 percent confidence level but assiduously avoid such a pill if it is established that it is “not lethal” at a 95 percent confidence level.
The results of the presidential election and the impact of Hurricane Sandy suggest that there might finally be some traction toward dealing with climate change. After a campaign devoid of its consideration, climate change was finally brought up by New York City Mayor Michael Bloomberg in his surprising last-minute endorsement of President Obama in the wake of Sandy. The President himself returned the issue to public light by speaking of it in his acceptance speech on election night:
“We want our children to live in an America that isn’t burdened by debt, that isn’t weakened by inequality, that isn’t threatened by the destructive power of a warming planet.”
Yet, to this point, little has been done. Neither New York City nor New Jersey, which took the brunt of Hurricane Sandy’s force, have made climate change response a serious priority, perhaps because doing so would create further tax burdens on a population already economically stretched. More cynically, while storm mitigation is largely a state and local expense, disaster clean-up garners major federal dollars. Irrespective of the reasons, much needs to be done and almost nothing has been done.
But is there an investment play here?
The reality of climate change doesn’t mean that there’s a trade to be made. Jeremy Grantham (see here) addresses the issue directly: Global warming will be the most important investment issue for the foreseeable future. But how to make money around this issue in the next few years is not yet clear to me.” I hesitate to disagree with Grantham because of the great respect I have for him, but disagree I do.
With the possible exception of the inverting demographic pyramid, I expect climate change to be the dominant investment challenge and opportunity of our time. But I don’t expect it to play out quickly. For most traders, an actionable item is one that can and should be undertaken right now and is expected to pay off essentially right away (not that there’s anything wrong with that). But no matter how often I point out that lunch tomorrow is not a long-range plan, I don’t seem to get heard all that often on this point. Yet I will not be deterred. Today I offer an action item that will almost surely pay off in the longer term for those with the necessary patience based upon any reasonable interpretation of the available data. The climate is changing and those changes will have to be dealt with sooner or later.
The denialists do not trouble me in the least. As Bruce Chadwick puts it, “if your investment horizon is long enough and your position sizing is appropriate, you simply don’t argue with idiocy, you bet against it.”
Investment opportunities in this area fall into two general categories. Climate mitigation focuses on reducing greenhouse gas emissions while climate change adaptation refers to actions taken to address the risks and opportunities associated with the physical effects of climate change such as changes to temperature, rainfall and ecosystems.
I remain unconvinced about the investment opportunities available with respect to mitigation. Since entrenched energy interests have a strong economic incentive to delay governmental initiatives towards climate mitigation, since climate denialists are likely to oppose such initiatives, and since it remains decidedly unclear which approaches will succeed (even assuming the “correct” approach(es) currently exist), Grantham’s uncertainty is well placed in this regard. From an investment perspective, we can avoid arguing about the causes of climate change — which are fraught with political peril despite science that is clear — and simply put our money to work in companies that deal with the consequences of climate change while avoiding those entities and regions with the most to lose.
Thus the better investment opportunities exist in climate change adaptation. Adaptation efforts include improved infrastructure design (Sandy clearly demonstrated the fragility of our energy infrastructure), more sustainable management of water and other natural resources, modified agricultural practices, and improved emergency responses to storms, floods, fires and heat waves. Infrastructural improvements include sea-walls, dykes, tidal barriers, and detached breakwaters. But since these improvements may have unintended and damaging side effects, for example by displacing erosion and sedimentation, we might also consider “softer” accommodation options that involve restoring dunes or creating or restoring coastal wetlands, or continuing with indigenous approaches such as afforestation.
Other accommodation options include warning systems for extreme weather events as well as longer-term measures such as improving drainage systems by increasing pump capacity or using wider pipes. Of particular interest ought to be food technologies that are resistant to heat, drought and flooding. Water needs provide opportunities in adaptation strategies for water conservation, storm water control and capture, resilience to water quality degradation, preparation for extreme weather events and diversification of water supply options.
Harsher and more wide-spread droughts will lead to a strain on communities and farmers that need fresh water. At the same time, rising sea levels will affect coastal regions, potentially leading to an increase of salt in ground water. So-called desalination technology has been a non-starter to this point; venture capitalists may want to re-think that. Other water recycling approaches are also promising. Further opportunities exist with respect to innovations in dealing with infectious diseases and pest control, weather forecasting technologies and more efficient irrigation systems.
Because the facts (and the science) are inexorable, society is going to have to adapt to higher temperatures and a rising sea level. Obviously, it’s much cheaper to deal with climate change before a crisis hits than after a city has been flooded. But there is no reason to believe or expect that we will have the public policy sense to do so. Moreover, green-energy technologies are still too speculative for the type of call I’m making here. The obvious investment priority is in adaptation technologies that will prepare and help us to deal with effects of climate change.
It is a highly speculative play. It is a very long-term play. But it is the right play. Our atmosphere is getting warmer and that has inevitable consequences. It is the most important hot action item of our time.
