Not exact matches

However, evolutionary theory does not consider such short time scales, but rather developmental changes occurring over millions of years.

«It's all about the time scale over which evolution occurs in relation to the timing of the changes now occurring in the environment, because there are likely to be mismatches,» he said.

«The climate transitions that we studied took place on millenial time scales, less than a thousand years, with some occurring over just decades to centuries,» Gibson says.

Theirs is the first study investigating land - atmosphere interactions to determine both the strength of the predictive mechanism between variables and the time scale over which these links occur.

«While methane and carbon dioxide emissions following thaw lead to immediate radiative warming,» the authors write, «carbon uptake in peat - rich sediments occurs over millennial time scales.»

Glasses have many important industrial applications, yet understanding the changes that occur over the wide range of time and length scales of the glass transition remains a challenge.

Fat loss only occurs on a total - body scale as you keep yourself in a calorie deficit over time.

There are of course other causes for other changes that have occurred, including suspected asteroid impacts, changes in volcanism over the eons which can lead to the buildup or reduction of greenhouse gases over long time scales, etc..

C is not constant for the dT» / dt equation to apply because heat penetrates through different parts of the climate system (different depths of the ocean in particular) over different time scales (also, if T» is supposed to be at some reference location or the global average at some vertical level, T» at other locations will vary; C will have to be an effective C value, the heat per unit change in the T» at the location (s) where T» occurs)

You are correct that regional and average weather changes over various time scales of interest, and that extreme events continue to occur.

GOAL 1: Examine the historical evolution of the arctic ice - ocean system from 1948 to 2003 to understand the large - scale changes that have occurred in sea ice and the upper Arctic Ocean over this time period.

Abstract — 2008 Climate and wildfires in the North American boreal forest... Climate controls the area burned through changing the dynamics of large - scale teleconnection patterns (Pacific Decadal Oscillation / El Niño Southern Oscillation and Arctic Oscillation, PDO / ENSO and AO) that control the frequency of blocking highs over the continent at different time scales......... Since the end of the Little Ice Age, the climate has been unusually moist and variable: large fire years have occurred in unusual years, fire frequency has decreased and fire — climate relationships have occurred at interannual to decadal time scales...... http://rstb.royalsocietypublishing.org/content/363/1501/2315.short ----------------------

If a scientist and in particular climate scientists don't understand the wide swings that do occur in data over short multidecadal time scales then how can they be trusted with understanding the large climatic swings on longer millenia time scales or vise - versa.

Over a time scale of decades, however, a possible self - sustaining decomposition of Yedoma could occur before the end of this century (Khvorostyanov et al., 2008a, 2008b, 2008c).

Several of the most difficult emerge from the long time - scale over which the changes occur (see Section 14.3) and the possible need for action well before the magnitude (and certainty) of the impacts is clear (see Section 14.5).

Rokdoc (65), so, since these changes will occur — on a geologic time scale, I must add — as they have over the last 500 million years, then we shouldn't worry about human actions inducing these same changes on the scale of human lifetimes?

If the sea level response to a change in temperature is an exponential decay to equilibrium then given that the 0.8 C temperature increase since pre-industrial times occurred over a relatively short time period relative to time scale of the ice - albedo feedback, the expected rate of sea level rise should be approximately 3 m / C * 0.8 C / 560 y = 43 cm per century.

Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming trend evident in instrumental temperature records over recent decades, although they do track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures over the full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).

Very dramatic warming effects occur on a vast time scale, over decades and centuries, so we are unlikely to witness them in our lifetimes.

Temperature increases in the thermocline occur on the decadal timescale whereas, over most of the abyss, it is the millennial time scale that is relevant, and the strength of MOC in the channel matters for the intensity of heat uptake.
