Not exact matches

Headed toward an 8 F rise in warming Other such low - probability but high - risk scenarios mentioned in the report include ecosystem collapses, destabilization of methane stored in the seafloor and rapid greenhouse gas emissions from thawing Arctic permafrost.

The long - term warming over the 21st century, however, is strongly influenced by the future rate of emissions, and the projections cover a wide variety of scenarios, ranging from very rapid to more modest economic growth and from more to less dependence on fossil fuels.

Emerging evidence for variability in the coral calcification response to acidification, geographical variation in bleaching susceptibility and recovery, responses to past climate change, and potential rates of adaptation to rapid warming supports an alternative scenario in which reef degradation occurs with greater temporal and spatial heterogeneity than current projections suggest.

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..

[*) That's a really rapid warming under both scenarios, considering the baseline (1961 — 1990, so not «preindustrial») and the used definition of future climate (2070 - 2100)-RSB-.

To say this another way, even if worst case warming scenarios with regards to feedbacks do emerge, all it does, from the human standpoint, is make rapid responses to climate change all the more urgent and necessary.

Lewis says there's evidence that temperatures both increased and decreased during the past 10,000 years «to a greater extent than the minimum warming scenario investigated by Thomas et al., and at a similarly rapid rate.»

The red line with yellow range represents the warming to come over the next 90 years in one of the more moderate IPCC business - as - usual emissions scenarios (A1B - rapid global economic growth with a balanced emphasis on all energy sources).

If today's worst - case global warming scenarios of catastrophic melting of glaciers and ice sheets come to pass, sea levels could rise rapidly, wreaking all sorts of geological havoc «comparable with the most rapid increases in sea level that we've seen in the last 15,000 years,» McGuire said.

There must have been brief periods of very rapid temperature change mixed in there (certainly on the regional level) in addition to slower - warming periods, and I'm under the impression other data (such as Greenland ice cores and deep - sea cores) support that scenario as well.
