Tradução de "World oil Reserves at "Tipping Point""

Grato desde já.

The World's capacity to meet projected future oil demand is at the tipping point, according to research by the Smith school of Enterprise and the environment at Oxford University.

There is a need to accelerate the development of alternative energy fuel resources in order to ensure energy security and reduce emissions, says a paper published in the journal energy policy. The age of cheap oil has now ended as demand starts outstrip supply as we head towards the middle of the decade, says the report. It goes on to suggest that the current oil reserve estimates should be downgraded from between 1150 - 1350 billion barrels to between 850 - 900 billion barrels, based on recent research. But how can potential oil shortage be mitigated ?

Dr Oliver Inderwildi, head of the Low Carbon Mobility center at the Smith School, said ' The common belief that alternative fuels such as biofuels could mitigate oil supply shortages and eventually replace fossil fuels is pie in the sky. There is not sufficient land to cater for both food and fuel demand. Instead of relying on those silver bullet solutions, we have to make better use of the remaining resources by improving energy efficiency. Alternatives such as a hydrogen economy and the Eletric transportation are not mature and we will only play a major role in the medium to long term.

Nick Owen, from the Smith School of Enterprise and the environment, added 'Significant oil supply challenges will be compounded in the near future by rising demanda and strenghtning environmental policy. Mitigating the oil crunch without using lower grade resources such as tar sands is the key to maintaining energy is stability and the low carbon future. 'The Smith school paper also highlights that in the past, political and financial objectives have led to misreporting over oil reserves, which has led to contradictory estimates of oil reserve data available in the public domain.

Sir David King, Director of the Smith School, commented: 'We have to face up to a future of oil uncertainty much like the global economic uncertainty we have faced during the past two years. This challenge will have a longer-term effect on our economies unless swift action is taken by governments and business. We all recognize that audio is a finite resource. We need to look at other low-carb on alternatives and make the necessary funding available for research, development and deployment today if we are to mitigate the tipping point.

The report also raises the worrying issue that additional demand for oil you could be met by nonconventional methods, such as the extraction of oil from Canada's tar sands. However, these methods have a far higher carbon output than conventional drilling, and have been described as having a double impact on emissions owing to the emissions produced during extraction as well as during usage.

Tipping point in Maths/Calculus means '"ponto de inflexão". Say, where in a quadratic function, a local maximum is placed, then the signal reverses (also called a "critical point").

Perhaps borrowed from this that comes the notion of "tipping point" used in journalese and other fields, to add drama, and sense of importance to a subject.


Ppaulo acho que ponto de inflexão seria "turning point".

No caso acho que ponto crítico seja a melhor tradução.

As reservas mundiais de petróleo estão em situação/ponto/momento crítico(a).

Agreed, you have a point (no pun intended). :lol:

A tipping point is often considered to be a turning point. in the sociological and other fields, in fact the term seems like
having come from Physics.

http://demonstrations.wolfram.com/Tippi ... ACylinder/
Tipping points are conditions in which the impetus for change becomes unstoppable. The term has been popularized in the sociological sense by Malcolm Gladwell's 2000 bestseller. But "tipping point" was originally a term in physics. A cylinder will fall to one of its stable orientations, either upright or to one side, depending on whether its tilt angle is less than or greater than its tipping point...

Then it came popular in other sciences in wich models are used, with a certain ring of "threshold" to it.

In Mathematics, the ''turning point'' would be more appropriate as Breck, has rightfully pointed out. As required by the academical rigor of the exact sciences.
