He believes that no one has thought of combining the two theories before because it's not an intuitive idea to look at how the effects of changing patterns of ocean circulation, which occur on time scales of thousands of years, would effect global silicate weathering, which in turn controls global climate on time scales of 100s of thousands of years.

«While the potential exists for rapid shifts in energy systems at the regional level, energy transitions tend to occur slowly on a global scale.

The big takeaway from this study: While there is uncertainty in projections for changes in the climate indices reviewed here (especially El Niño and La Niña), this study serves to alert us to the fact that the climate impacts that our local coastal communities face are based in large part on changes that occur on both a large, global scale and over the long, decadal term.

Terrestrial permafrost emissions of CH4 and CO2 likely can occur on a time scale of a few decades to several centuries if global warming continues [215].

... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and global mean temperature... Polar amplification occurs if the magnitude of zonally averaged surface temperature change at high latitudes exceeds the globally averaged temperature change, in response to climate forcings and on time scales greater than the annual cycle.

(57k) When I state that the equilibrium climatic response must balance imposed RF (and feedbacks that occur), I am referring to a global time average RF and global time average response (in terms of radiative and convective fluxes), on a time scale sufficient to characterize the climatic state (including cycles driven by externally - forced cycles (diurnal, annual) and internal variability.

Since a primary driver of the Earth's climate from year to year is the El Nino Southern Oscillation (ENSO) acts on time scales on the order of 2 - 7 years, and the fact that the bulk of the Southern Hemisphere hurricane season occurs from October — March, a reasonable interpretation of global hurricane activity requires a better metric than simply calendar year totals.

Led by Dr. James E. Hansen from 1981 to 2013, research at GISS emphasized a broad study of global change, which is an interdisciplinary initiative addressing natural and man - made changes in our environment that occur on various time scales — from one - time forcings such as volcanic explosions, to seasonal / annual effects such as El Niño, and on up to the millennia of ice ages — and that affect the habitability of our planet.

When the climates of the more local high - latitude Pacific and Atlantic sectors varied in parallel, large, abrupt climate fluctuations occurred on a more global scale.

The instabilities in the climate system and the movement from global warming to global heating kicks in above 350 ppm, so that as the ppm increase, mitigation opportunities are lost and catastrophic harms on an even grander grand scale (as noted by Mike) will continue to occur to human and other life forms.

Future coupling of demography with existing global land model predictions could enable assessment of these potentially important die - off responses [44], as well as implementation of more realistic reductions in tree loss to drive scenarios (i.e., enabling assessments of ecological changes less drastic or occurring on shorter time - scales than conversion from forest to grassland biomes).

Note that I am not necessarily claiming that this is the feedback operating on the long time scales associated with global warming — only that it is the average feedback involved in the climate fluctuations occurring during the period when the satellite was making its measurements.

Methane hydrates — methane molecules trapped in frozen water molecule cages in tundra and on continental shelves — and organic matter such as peat locked in frozen soils (permafrost) are likely mechanisms in the past hyperthermals, and they provide another climate feedback with the potential to amplify global warming if large scale thawing occurs [209]--[210].

As long as we are tossing around fabricated statistics, there is a 100 % chance that climate is going to occur and 0 % that mankind can do to control climate on a global scale.

That conclusion is based not on climate models or recent trends in forest fires, but rather on records of forest fires that occurred more than a millennium ago, during the Medieval Climate Anomaly, a period when global temperatures were comparable to what they are today, and about half a degree warmer (on the Celsius scale) than they had been for several centuries prior.
