Dr Stephen Grimes of Plymouth University, who initiated the research project, highlighted the climate changes that must have caused this increase in sediment erosion and transport — «We have climate model simulations of the effect of warming on rainfall during the PETM event, and they show some changes in the average amounts of rainfall, but the largest change is how this rainfall is packaged up — it's concentrated in more rapid, extreme events — larger and bigger storms.»

The discovery of other, smaller magnitude, rapid greenhouse warming events (called hyperthermals) in the millions of years following the PETM provides further opportunities to examine the response of organisms to global climate change.

There has been an ongoing debate, both in and outside the scientific community, whether rapid climate change in the Arctic might affect circulation patterns in the mid-latitudes, and thereby possibly the frequency or intensity of extreme weather events.

In other words, a DO event (brought on this time by anthropogenic global warming) should be seen as larger and more rapid climate change than anthropogenic global warming.

The two kinds of climate change are sometimes confounded by non-experts — e.g., when it is claimed that DO events represent a much larger and more rapid climate change than anthropogenic global warming.

The point I am trying to make is «when it is claimed that DO events represent a much larger and more rapid climate change than anthropogenic global warming,» perhaps DO events do cause rapid regional climate change larger and more rapid than anthropogenic global warming generally.

The end of the first half of the Holocene — between about 5 and 4 ka — was punctuated by rapid events at various latitudes, such as an abrupt increase in NH sea ice cover (Jennings et al., 2001); a decrease in Greenland deuterium excess, reflecting a change in the hydrological cycle (Masson - Delmotte et al., 2005b); abrupt cooling events in European climate (Seppa and Birks, 2001; Lauritzen, 2003); widespread North American drought for centuries (Booth et al., 2005); and changes in South American climate (Marchant and Hooghiemstra, 2004).

The symptoms from those events (a big, rapid jump in global temperatures, rising sea levels, and ocean acidification) are all happening today with human - caused climate change.

In a report released yesterday in Washington by the National Research Council, the research arm of the National Academy of Sciences, a panel of 11 scientists examined the possibility of abrupt climate change, in which small events can bring on rapid and great consequences.

Past rapid rapid climate change events are marked by mass extinctions such as the End Permian.

That is, they fear that global temperatures will exceed a tipping point that will trigger a release of stored carbon from the biosphere, an event that would cause further rapid climate change.

«Since such rapid climate change would challenge even the most modern societies to successfully adapt, knowing how these massive events start and evolve is one of the most pressing climate questions we need to answer.»

There is an inevitable time delay between the occurrence of an event and the complete dissection of its various causes, but a rapid - response study by NOAA scientists has already concluded that climate change made the Baton Rouge flood 40 percent more likely to occur in 2016 than in 1900.

Since the end 10,000 years ago of the last ice age — itself a very rapid event — was the springboard for agriculture and civilisation, and eventually an Industrial Revolution based on fossil fuels, the story of climate change plays a powerful role in human history.

David has been a leading voice in arguing for rapid action on climate change, and I think he makes a powerful case that the choice is between increasingly extreme and frequent weather events, or returning to a safe climate.

«The rapid climate changes known in the scientific world as Dansgaard - Oeschger events were limited to a period of time from 110,000 to 23,000 years before the present,» said Xu Zhang, the report's lead author.

For example, the National Academies recently published a study on the attribution of extreme events in the context of climate change, noting that «advances have come about for two main reasons: one, the understanding of the climate and weather mechanisms that produce extreme events is improving, and two, rapid progress is being made in the methods that are used for event attribution.

The study, published Sunday in the journal Nature Climate Change, is the first to find correlations between rapid Arctic warming and extreme summer weather events, since previous research had focused on the links between Arctic warming and fall and winter weather patterns.

But the lack of statistically significant results and, more important, the absence of evidence pointing to a smoking gun — a physical mechanism in the climate system that ties Arctic changes to extreme events — has left many top climate researchers unconvinced that rapid Arctic warming is a major player in causing extreme weather events outside of the Arctic itself.

To asses the risk associated with a particular event we must know first of all the probability of that event occurring (i.e. how likely is it that the Arctic will be seasonally ice free by 2020) and calculate a measure of the harm / hazard if this event were it to occur (i.e. a rapid acceleration of climate change).

Seems to me David's mistake is not noticing that the rapid events are internal to the climate system, not external; they may cause fast changes in albedo for example for a while; and they are modeled, see Dr. Bitz's work on Arctic sea ice, or any model including volcanos or Atlantic deep water currents etc..
