Sentences with phrase «ice core data suggest»

Greenland ice core data suggest that the Greenland ice sheet response to Eemian warmth was limited [91], but the fifth IPCC assessment [14] concludes that Greenland very likely contributed between 1.4 and 4.3 m to the higher sea level of the Eemian.

Ice core data suggest that the Greenland Summit region was ice - covered during this period, but reductions in the ice sheet extent are indicated in parts of southern Greenland.

Which is not surprising, given that the ice core data suggest that this feedback only sets in with a delay of hundreds of years after the warming starts.

The ice core data suggest that Svalbard's climate was about as mild in the 1300s as it is today.

Ambrose also cites Greenland ice core data that suggest sulfur stuck around in the atmosphere longer than just a few years and that Earth had already entered a cold snap.

Data on greenhouse gas abundances going back beyond a million years, that is, beyond the reach of antarctic ice cores, are still rather uncertain, but analysis of geological samples suggests that the warm ice - free periods coincide with high atmospheric CO2 levels.

fhhaynie For the empirical ice core and proxy temperature data on which the 1000 year cycle is based see Figs 6 and 7 in the latest post at http://climatesense-norpag.blogspot.com Interestingly Fig 6 also suggests that if you believe (which I obviously don't) that CO2 is the main climate driver - its long term effect is to cool the earth.

* An exponential fit hindcasts absurdly, namely to zero when the ice core data from Vostok etc. would suggest 280 - 290 as a more reasonable hindcasting target.

This is only suggested by ice - core paleoclimate data which is ultimately uncheckable by direct empirical observation.

Very few (1 - 2 points) of ice core C13 data (Francey tellus, 99) suggest that this drawdown was caused by additional terrestrial carbon storage (Joos et al, GRL, 99; Trudinger, Tellus, 99).

Data from ice core records strongly suggest that the prehistoric carbon dioxide changes were largely a response, not a cause, of temperature changes.

Ice cores from there in 1966, and others from the Dye 3 site in southern Greenland in 1981, suggested some abrupt changes but various objections were raised to parts of the data.

I spent a week listening to 80 paleoclimatoligists and climate modelers argue about the interpretation of the data from ice and sediment cores, how it eliminated some proposed explanations for what was driving the changes in temperature and rainfall, and how it suggested other possible explanations.

I don't mean to step on Michael Tobis» toes, but the level of CO2 has always so far as the various ice core and like data strongly suggest (above 99.5 % with consilience) been seasonally variable over land due to interaction of plants and temperature as proven by NH / SH trends, just as it is diurnally variable due to photosynthesis.

Hi John, Although proposed at 1470 years based on a single ice - core, GISP2, more recent data suggests it is closer to 1500 than 1470 years.
