What Are The Economic Impacts Of Climate Change – Hsiang, S., Kopp, R.E., Jina, A., Rising, J., Delgado, M., Mohan, S., Rasmussen, D.J., Muir-Wood, R., Wilson, P., Oppenheimer, M., Larsen, K. and Hauser, T. (2017). Estimating the economic damage from climate change in the United States.

Calculating the damage of climate change is important in the design of climate policies. Here, we develop a flexible architecture for damage estimation that integrates climate science, econometric analyses, and process models. We use this approach to produce spatially robust, probabilistic, and empirically derived estimates of economic damage in the United States from climate change. The combined value of market and non-market damage in the analyzed sectors – agriculture, crime, coastal storms, energy, human deaths and labor – increases quadratically with the average global temperature, averaging about 1.2% of the gross domestic product for +1 ° C constitutes Importantly, risk is unevenly distributed between locations, creating a large transfer of value to the north and west, increasing economic inequality. By the end of the 21st century, the poorest third of counties will lose between 2 and 20% of county income (90% probability) from typical waste (Representative Concentration Pathway 8.5).

Province-level damage by sector (CSV) – This file contains the average damage for each sector shown in Figure 2 of the main article (agriculture, mortality, energy, low-risk work, high-risk work, coastal damage, property crime, violence crime, general damage). These impacts are central estimates of average annual damage over the years 2080-2099 based on the common scenario (RCP8.5).

Webcast #2: Options For Estimating The Global Economic Impacts Response To A Future Climate

In a study recently published in the journal Science, researchers calculated the economic and other consequences of U.S. warming down to the county level.

Climate change is real and it is dangerous. The world’s scientists pretty much agree on this, even if a few misguided and disingenuous politicians bury their heads in the shifting sands and rivers above.

Calculating the economic consequences of climate change is not a simple task. This means determining how global temperature increases will affect local weather conditions; how local weather affects things like crop mortality and yield; how these changes add…

To the atmosphere causing global warming is now controversial. However, scientific and political recognition of this reality has not yet translated into a commitment to reducing emissions to halt further global warming. As a result, economists are tasked with assessing the economic costs of climate change and developing policies to address them. This assessment is important: the world cannot embark on ambitious efforts to reduce carbon emissions unless we are reasonably certain that the benefits of these actions will outweigh their costs.

Estimating the economic impact of climate change is difficult. First, there is natural science. Models that map carbon emissions to global and local temperature changes are readily available, but mapping many other physical effects, such as sea level rise, extreme weather events, or nonlinearities in the climate system, is more complex. Although our understanding of these impacts is improving, as the latest Intergovernmental Panel on Climate Change report shows, there are still no good off-the-shelf models that we can easily incorporate into our economic analysis.

Second, climate change develops relatively slowly, over decades and centuries rather than months and years. Although anthropogenic temperature change is already affecting our present-day reality, many of its negative effects will only be felt in the distant future. Assessing the consequences of warmer temperatures in the distant future requires dynamic models, as has been recognized since the pioneering work of William Nordhaus. These long-term effects limit the usefulness of small-scale experimental studies: extrapolation so far from the sample is inappropriate and does not recognize the ability of people to react, respond and adapt to changing conditions. Lucas’s criticism—that historical data on economic policy outcomes cannot be used to accurately predict future policy outcomes because people’s behavioral responses also change over time—bites hard here.

Rapidly mixing in the atmosphere, emissions from every part of the planet cause temperature changes around the world. Consequently, any attempt to assess the economic impacts of climate change must be global in nature. At the same time, an integrated dynamic model of the global economy is not sufficient if it ignores spatial diversity. How can we discuss the effects of coastal flooding without acknowledging the difference between Miami and Dallas, or without considering that people may move inland to escape flooding? And how can we estimate the value of a 1°C increase in global temperature without recognizing that it would result in more than 2°C in northern latitudes but only 0.5°C in some equatorial regions? Perhaps more importantly, how can we make a comprehensive assessment if we ignore that higher temperatures have very different economic impacts in the coldest and warmest regions of the world? Recognizing this spatial heterogeneity is essential to accurately assess not only the cumulative effects of climate change, but also the spatial disparities it may produce.

Factor 3: Socio Economic Risk

Based on these observations, we recognized the need for economic climate assessment models that clearly take into account both temporal and spatial dimensions. As temperatures and sea levels change, individuals and companies will respond, and an important part of this adaptation will occur not within locations but between locations. Incorporating these behavioral responses requires models with realistic geographies of the global economy that include trade and migration linkages across space. In addition, such models must recognize that the geography of the world’s productive capacity is not immutable. Where economic activity is concentrated varies significantly over time. China’s rise as a manufacturing powerhouse is just one example of these geographic shifts. As the climate changes, areas that benefit from warmer temperatures will see investment and growth. To account for this, climate assessment models must allow for growth to vary endogenously across regions.

Over the past decade, we have adopted a research program to develop quantitative spatial dynamic models to assess the economic impacts of climate change. In doing so, we continue a long tradition of using assessment models that integrate key insights from climate science into economic modeling. The difference is that we bring the spatial-dynamic aspect to the fore. There are various predictions, but we first introduced a model with some of these features in 2014.

It includes growth and investment in a one-dimensional framework with a continuum of locations, two sectors, high-value trade and free immigration.

In 2015, we used this framework to study the impact of global warming on industry specialization, trade and mobility.

As a first step, a one-dimensional framework that focuses on differences across latitudes and ignores differences across longitudes is reasonable: only 5 percent of global temperature variation occurs within latitudes.

This study helped us understand the importance of changes in the spatial distribution of economic activity in determining the economic costs of global warming. The logic is simple, but we believe it is compelling. If moving around is cheap, especially over decades or centuries, and if global warming hurts some places but not others, then changing the spatial distribution of economic activity can be a powerful way to reduce the losses from climate change. This adaptation mechanism is particularly strong if land is abundant in areas that could benefit from rising temperatures, such as Alaska, northern Canada, and Siberia.

The inescapable conclusion is that the losses from climate change must be greatly increased
