But the problem with building the science of extreme events is that, by definition, they are rare.

Because these moderate extremes are by definition more common, and because the authors looked at global statistics rather than those for highly localized, rare events, the conclusions are extremely robust, said Peter Stott, leader of the Climate Monitoring and Attribution Team at the Met Office Hadley Centre, in the U.K. «I think this paper is very convincing,» said Stott, who was not involved in the research.

Trends are important because they eliminate - or «smooth out» - single events that may be extreme, but quite rare.

In his book Fooled by Randomness, Nassim Taleb defined Black Swan (the term refers to the once prevalent old world belief that all swans are white, which was proven false when black swans were discovered in Australia) as a rare event that is (1) unexpected (2) carries an extreme impact and (3) believed to be predictable in hindsight.

The two most fundamental properties of extreme events are that they are rare (by definition) and highly random.

What this shows first of all is that extreme heat waves, like the ones mentioned, are not just «black swans» — i.e. extremely rare events that happened by «bad luck».

Unfortunately what extreme events tend to do for a living is to be rare.

So it captured extreme inland rainfall from tropical systems (as in this system, Irene, Floyd, and Vermont's epic 1927 gullywasher) as well as nor - easters and any other rare events.

Because these events were rare before human GHG emissions forced more energy (heat) into the atmosphere, it is reasonable to conclude that AGW is responsible for (is the cause of) the most extreme events.

It's a daunting task to try to detect any links between short - term fluctuations in extreme weather events and the rising influence of accumulating greenhouse gases on climate, given that extreme weather is, by definition, rare.

The key thing (as I understand it) is how changing the climate is going to influence events that we currently regard as extreme and, hence, rare.

If anything, I think a key point in the post (and it would be good to check that this is what Rasmus was getting at) is that climate change will almost certainly impact the distribution of events and, hence, will almost certainly influence those events that we currently regard as extreme / rare.

Also, because, by their very nature, extreme events are rare, it would not be possible to have a meaningful statistical trend until a large amount of global warming had already happened.

On rare occasions their timing is such as to result in an interaction which can lead to an extreme event along the eastern seaboard.

The first question that we want to answer is how rare is that event in observed record: Is this event the most extreme?

Importantly, they found that SLR will result in stronger increases in the number of moderate (or high - frequency) events in some places, e.g. Charleston or New York on the east coast, whereas other areas will experience a more rapid increase in the number of rare extreme (or low - frequency) events, e.g. Seattle on the west coast.

It focuses on weather and climate extremes that are defined as rare events within the statistical reference distribution of particular weather elements at a particular place.

In most regions, instrumental records of variability typically extend only over about 150 years, so there is limited information to characterise how extreme rare climatic events could be.

When an extreme climate event takes place, a range of users would like to know as soon as possible not only how rare this particular event is but also whether it could be attributed to climate change or if, instead, it is part of the climate variability one would expect in the absence of climate change.
