How It All Began by See Review Comments at the end of this Paper Imagined risk All available evidence indicates that man-made global warming is a physical impossibility, but if the predicted warming could be induced it would probably provide net benefits. However, there is a widespread imagined risk of the warming and politicians are responding to it. Responses to imagined risk are often extreme and dangerous.
In common language equity means "the quality of being impartial" or "something that is fair and just. Chitre argues, and Emerging markets countries, such as India and China, often would rather analyze Per capita emissions instead of committing to aggregate Emissions reduction because of historical contributions by the Industrialized nations to the climate change crisis, under the principle of Common But Differentiated Responsibilities.
The IPCC's later " SRES " scenarios, published inexplicitly explore scenarios with a narrowing income gap convergence between the developed and developing countries.
Climate change scenario Projected total carbon dioxide emissions between — using the six illustrative "SRES" marker scenarios.
Some of these projections aggregate anthropogenic emissions into a single figure as a " carbon dioxide equivalent " CO2-eq. The effects of aerosol and land-use changes e. Six of the SRES emissions scenarios have been used to project possible future changes in atmospheric CO2 concentrations.
Uncertainties such as the removal of carbon from the atmosphere by " sinks " e.
Atmospheric GHG concentrations can be related to changes in global mean temperature by the climate sensitivity. Hope for example, found that uncertainty over the climate sensitivity was the most important factor in determining the social cost of carbon an economic measure of climate change impacts.
Cost—benefit analysis[ edit ] Standard cost—benefit analysis CBA  also referred to as a monetized cost—benefit framework  can be applied to the problem of climate change.
If, for example, some countries were to benefit from future climate change but others lose out, there is no guarantee that the winners would compensate the losers;  similarly, if some countries were to benefit from reducing climate change but others lose out, there would likewise be no guarantee that the winners would compensate the losers.
This criterion has been justified on the basis that: This contrasts with a strategy in which no action is taken until research resolves all key uncertainties. One of the problems of climate change are the large uncertainties over the potential impacts of climate change, and the costs and benefits of actions taken in response to climate change, e.
A near-term hedging strategy concerned with reducing future climate impacts might favour stringent, near-term emissions reductions. To put it differently, stringent near-term emissions abatement can be seen as having an option value in allowing for lower, long-term stabilization targets.
This option may be lost if near-term emissions abatement is less stringent. This may suggest an approach where near-term emissions abatement is more modest. Economics of climate change mitigation The mitigation portfolio.
The first were resilient strategies. This seeks to identify a range of possible future circumstances, and then choose approaches that work reasonably well across all the range. The second were adaptive strategies. The idea here is to choose strategies that can be improved as more is learned as the future progresses.
Granger Morgan et al. Portfolio theory[ edit ] An example of a strategy that is based on risk is portfolio theory. This suggests that a reasonable response to uncertainty is to have a wide portfolio of possible responses.Ten years ago, Al Gore claimed we had 10 years to save the planet from global warming, as pointed out in this Communist BS (CBS News) report from early Unless drastic measures to reduce greenhouse gases are taken within the next 10 years, the world will reach a point of no return, Gore said.

Sep 25, · timberdesignmag.com popular website Global warming: it’s a big topic these days, and people want to know what they can do to help. Most people don’t realize it, but one way to reduce global warming is to recycle paper products.
Paper recycling helps in the following ways: Energy Savings-Pulp and paper Read moreThe Connection Between Recycling and Global Warming. Modern Global Warming (MGW) is the change in climate that has been taking place from the coldest period of the Little Ice Age (LIA) to the present.
It is characterized by a preponderance of warming periods over cooling periods, resulting in the warming of the planet, expansion of tropical areas.
The Pros and Cons of Global Warming - The climate on the Earth is changing. Ice age is interleaved with the global warming.
In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming.
