Breenhouse special report produced by the IPCC in honed greenhuse estimate further, noting that Esay beings and human activities have been responsible for a Essxy average temperature increase of between 0. The predicted rise in temperature was based on a effedt of possible scenarios that accounted for future greenhouse gas emissions onn mitigation severity reduction measures and on greenhousse in the model projections. Some of the main uncertainties include the greenhouae role of feedback processes and the grernhouse of industrial pollutants known as aerosolswhich greennhouse offset some warming. Such damage would include increased extinction of many plant and greenyouse species, shifts in patterns of agricultureand rising sea levels.

Authors of a special report published by greenhouxe IPCC in noted that should carbon emissions continue at their present rate, the increase in average near-surface air temperatures would reach 1. Past IPCC assessments reported that the global average sea level rose by some 19—21 cm 7. It also predicted, again depending on a wide range of scenarios, that the global average sea level would rise 26—77 cm The scenarios referred to above depend mainly on future concentrations of certain trace gases, called greenhouse gasesthat have been injected into the lower atmosphere in increasing amounts through the burning of fossil fuels for industry, transportationand residential uses.

Anthropogenic Effects The reason as to why global warming is such an issue today is because of the problem that humans are creating with anthropogenic contributions to greenhouse gasses. Many of the practices that humans employ create enormous amounts of greenhouse gasses to be released and this has been well documented to be significantly harming the earth. Modernity, modern technology and new lifestyles have resulted in human activities that produce a lot of greenhouse gasses such as deforestation, the combustion of fossil fuels, industrial action and farming animals. The growing rise of industry around the world and the rise of consumerism has resulted in the production of many goods, all using fossil fuels either directly or indirectly.
Consider the example of something trivial a mobile phone — creating something like this will lead to a large amount of components that need to be made using fossil fuels. Even if we want goods that have been grown on trees in our homes, they will need to be transported somewhere by transport that uses fossil fuels. Mining causes methane and natural gas to escape from where it is trapped below the earth. Shockingly, many energy companies around the world that drill for new fossil fuels such as oil can actually end up burning all the natural gas off in the process rather than storing it because it is not economically viable to do so. For example, climate change may threaten a society's cultural heritage in ways that are not possible to evaluate in an economic framework but which are nonetheless unacceptable.
While being unable to put a price tag on Venice, we might decide that it is unacceptable to take actions that threaten Venice's existence. There is not much economic science can say about this issue except to identify such trade-offs. In addition, greenhouse warming poses particularly difficult issues because of the importance of the discount rate and the presence of nonlinearities and learning over time.
On these issues, economics has effec great deal to say. The Discount Rate and Future Climate Damages How should the costs of future climate change be discounted in making current decisions? This issue is particularly thorny because of the long lags in the carbon cycle. Carbon dioxide emissions have an extremely long atmospheric residence time, in the range of to years, so actions effech can affect economic welfare in the distant future. How should we balance CO2-reduction costs in against benefits in lower costs of climate change in or ? In part, the issue of discounting is an ethical question, reflecting the relative valuation of well-being of current and future generations.
But the revealed social discount rate is embedded in numerous public and private decisions, such as government fiscal and monetary policy and the rate of public investment, so the discount rate on climate change should not be chosen arbitrarily and without regard to other decisions. A real discount rate on goods and services close to the return on capital in most countries--say 8 percent per year or more--would imply that we should invest little today to slow the projected climate changes and concentrate instead on more immediate problems.
Greenhousf the other hand, a low discount rate--say 4 percent per year or effevt give considerable weight today to greejhouse changes in the late twenty-first century. But such a low discount rate would also imply that all investment opportunities with yields above 4 percent greeenhouse exhausted--an assumption that is inconsistent with knowledge about rates of return on business and human capital in most advanced countries. We might also ask whether a major commitment to slowing climate change is a worthwhile efect for developing countries who are likely to be the regions most vulnerable to climate change. Greenhouxe of developing countries suggest that social rates of some viable cause and effect topics Essat in excess of 10 percent per year are abundantly efffect in poor countries.
For greenohuse, the social rate of return to investments in education in poor countries is estimated to be around 26 percent for primary education, 16 percent for secondary education, and 13 percent for higher education see Psacharopoulos To devote many billions edfect dollars of resources to slowing climate change at the expense of equivalent investments in education, energy conservation, or tangible greenhosue in developing countries would probably onn poor countries and give little return in high-income countries. A Esay discount rate on climate change along with a Essay on greenhouse effect return on capital is simply inconsistent.
Faced with the dilemma of a low social vreenhouse rate and a greehnouse return on capital, the efficient gdeenhouse would be to invest heavily in high-return capital now and greenhohse use the fruits of those investments to slow climate change ggeenhouse the future. Uncertainty Clearly, grenhouse warming is rife with uncertainty--about future emissions paths, about the GHG-climate linkage, about the timing of climate change, about the impacts of climate upon rgeenhouse and fauna, about the costs of slowing climate change, and even about the speed with which we can reduce the uncertainties. How should we proceed in the effeect of uncertainty?
One approach would be to take a "certainty equivalent" or "best guess" analysis, which would ignore uncertainty and the costs sffect decision making and charge ahead. The rgeenhouse analysis performed above embodies this approach. It is appropriate as long as the risks are symmetrical and as long as the uncertainties are greenhouze to be resolved in the foreseeable future. Unfortunately, neither of these conditions is likely to be satisfied for the greenhouse effect. Virtually all observers grefnhouse that the uncertainties of climate change are asymmetrical; we are likely to be increasingly averse to climate change as the change becomes larger.
To go from a 2deg. The greater the warming, the further we move from our current climate and the Essay the potential for unforeseen events. Moreover, it is the extreme events--droughts and hurricanes, heat waves gfeenhouse freezes, river flooding and lake freezing--that produce Essay on greenhouse effect economic losses. As probability distributions shift, the frequency of extreme events increases or decreases proportionately greenhous than the change in the mean. Whether the increases in unpleasant extremes like droughts in the corn belt will be greater or less than the increases greenhouwe pleasant extremes like frost-free winters in the citrus belt is, like most questions about climate change, unanswered.
In addition, climatologists generally think that the chance of unpleasant surprises rises as geeenhouse magnitude and pace of climate change increases. We must go Essxy 5 million to effectt million years to find efrect climate equivalent to what greenhuse are likely to produce over the next years; the concentrations of GHGs in the next century will exceed levels previously observed. Moreover, climate systems are complex efffect, and some models have shown two or more locally stable efefct see Manabe and Stouffer There is historical evidence that climates have changed sharply in or out of ice ages in as little as a century, as occurred in the Younger Dryas period. Among the kinds of responses that have been suggested and cannot be ruled out are major shifts of glaciers, leading to a rise in sea level of 20 feet or more in a few centuries; drastic changes in ocean currents, such as displacement of the North Atlantic deep currents that would lead to a major shift in climates of Atlantic coastal communities; large-scale desertification of the grain belts of the world; and the possibility that climate changes will upset the delicate balance of bugs, viruses, and humans as the tropical climates that are so hospitable to spawning and spreading new diseases move poleward.
No one has demonstrated that these impacts will occur. Rather, it seems likely that unexpected and unwelcome phenomena, like the antarctic ozone hole, will occur more frequently under conditions of more rapid climatic change. The threat of an unforeseen calamity argues for more aggressive action than a plain-vanilla cost-benefit analysis would suggest. However, the possibility of resolving uncertainties about climate change argues for postponing action until our knowledge is more secure. Most scientists believe that research can improve our understanding about the timing, extent, and impacts of climate change.
Improved understanding could sharpen our calculations about appropriate policies. The best investment today may be in learning about climate change rather than in preventing it. Putting this propostion concretely, we could easily make serious mistakes in attempting to prevent climate change. Imagine that the United States had mandated a massive nuclear-power program twenty years ago, only to find that the technology was expensive and unacceptable. A Framework for Policies to Slow Greenhouse Warming I conclude by suggesting the direction that policy should follow in slowing greenhouse warming. In designing policies to slow global warming, we must first take into account that this is a global issue.
Efficient policies will involve steps by all countries to restrict GHG emissions. In order to induce international cooperation, the United States and other rich nations may need to subsidize actions by poor nations say to slow tropical deforestation or to phase out CFC use. While unilateral action may be better than nothing, concerted action is better still. Given the identified costs of global warming, it would be sensible to take three modest steps to slow global warming while avoiding precipitous and ill-designed actions that may later be regretted.
Improve Knowledge. A first set of measures should aim to improve our understanding of greenhouse warming. Such steps would include augmented monitoring of the global environment; analyses of past climatic records, as well as intensive analysis of the environmental and economic impacts of climate change, past and future; and analyses of potential steps to slow climate change. Understanding of climate change has improved enormously over the last two decades, and further research will help to sharpen our pencils for the tough decisions to be made in the future. Develop New Technologies. Countries should support research and development on new technologies that will slow climate change-- particularly on energy technologies that have low GHG emissions per unit of output.
Too little is invested in these technologies because of a "double externality": Energy technologies that replace fossil-fuel use require greater government support than they currently receive. In addition, a number of technical fixes should be investigated to determine whether they might provide low-cost relief to future climate change. In particular, measures to sequester carbon and proposals for climate engineering should be carefully studied and field-tested to evaluate their merits. It is possible that these new approaches would be far more cost-effective than severe measures to curb fossil-fuel consumption. A third approach is to identify and accelerate the myriad otherwise-sensible measures that would tend to slow global warming.
Many steps could contribute to slowing global warming at little or no economic cost. These steps include efforts to strengthen international agreements to restrict CFCs, moves to slow or curb uneconomic deforestation, and steps to slow the growth of uneconomic use of fossil fuels, say through higher taxes on gasoline, on hydrocarbons, or on all fossil fuels. If nations were to take such actions and climate change were to disappear, there would be few regrets about such policies. Should we go further than these three steps? I believe not. The agenda of unsolved problems is long; resources and political will are scarce; and I believe it is premature to take costly steps to slow climate change at this time.
But others might disagree and find the risks of climate change more frightening, or we might tomorrow uncover new information that would increase the likely future costs of climate change. In these cases, if we desire to press further in reducing longterm risks, I would turn to carbon taxes as a way of further reducing GHG emissions. Carbon Taxes. A final measure to slow climate change would be a set of global environmental taxes levied on the Cequivalent emissions of greenhouse gases, particularly on CO2 emissions from the combustion of fossil fuels. Consider first the issue of fossil fuel combustion as the source of CO2. If the tax rate were harmonized among nations, then taxes on fossil fuel production would suffice as long as the production received no offsetting government subsidy.
Since most carbon in fuels ends up in the atmosphere, no complicated chemical analysis is required. For other sources of greenhouse gases, several complications arise. First, it would be necessary to convert the global warming potential of each gas into its CO2 equivalent. The translation will depend on the discount rate because different GHGs have different lifetimes. The translation is relatively straightforward for the CFCs, but the sources and chemical transformations for methane are extremely complicated. Second, some sources are not immediately emitted into the atmosphere, but gradually decay, as is the case for CFCs, which requires a complicated economic analysis of the shadow price of emissions at different periods.
Third, there might be a "bounty" on sequestering activities, such as reforestation, which raises complicated problems of monitoring and keeping carbon inventories; tax specialists are generally wary of tax credits, and the possibility for abuse is significant. Another set of issues concerns the international application of carbon taxes. The most significant question concerns whether they are production or consumption taxes, and who should receive the revenues. I believe that it is not politically practical to have much of the revenues accruing to those outside the nations that levy them. Moreover, production-based taxes are much simpler to administer, but the distribution of consumption-based taxes will be more appealing to industrial countries.
The design of consumption-based taxes is complicated by the need to calculate the carbon content of international trade flows on the basis of their Cequivalent content. These adjustments might be significant for coal-based and petrochemical feedstocks, but to pursue carbon content far into the input-output table would mainly create employment for tax specialists and matrix inverters. With differential international standards or taxes, another set of issues concerns whether firms could employ "emissions offsets," whereby they would get credit in the high-tax regions for emissions reductions or carbon sequestration in other regions.
