Sentences with phrase «global ice volume records»

John Imbrie used time - series analysis to statistically compare the timing and cycles in the sea surface temperature and global ice volume records with patterns of the Earth's orbit.

Abstract: Mid - to late - Holocene sea - level records from low - latitude regions serve as an important baseline of natural variability in sea level and global ice volume prior to the Anthropocene.

The stack of 57 globally distributed benthic δ18O marine records (dark grey), a proxy for global ice volume fluctuations (Lisiecki and Raymo, 2005), is displayed for comparison with the ice core data.

With error bars provided, we can use the PIOMAS ice volume time series as a proxy record for reality and compare it against sea - ice simulations in global climate models.

However, atmospheric CO2 content plays an important internal feedback role.Orbital - scale variability in CO2 concentrations over the last several hundred thousand years covaries (Figure 5.3) with variability in proxy records including reconstructions of global ice volume (Lisiecki and Raymo, 2005), climatic conditions in central Asia (Prokopenko et al., 2006), tropical (Herbert et al., 2010) and Southern Ocean SST (Pahnke et al., 2003; Lang and Wolff, 2011), Antarctic temperature (Parrenin et al., 2013), deep - ocean temperature (Elder eld et al., 2010), biogeochemical conditions in the Northet al., 2008).

Except that we do make an attempt to validate the model with respect to how it has performed against the best estimate of global ice volume we have — Shackleton's 2000 record (I might add that I am not sure of any other modeling study that has tried to validate itself against the Shackleton record).

From historic droughts around the world and in places like California, Syria, Brazil and Iran to inexorably increasing glacial melt; from an expanding blight of fish killing and water poisoning algae blooms in lakes, rivers and oceans to a growing rash of global record rainfall events; and from record Arctic sea ice volume losses approaching 80 percent at the end of the summer of 2012 to a rapidly thawing permafrost zone explosively emitting an ever - increasing amount of methane and CO2, it's already a disastrous train - wreck.

We'll see very soon, if Wyatt is correct then no global temperature record nor a record low sea ice extent, area or volume within the next year.

«Every piece of valid evidence â $» long - term temperature averages that smooth out year - to - year fluctuations, Arctic sea ice volume, melting of glaciers, the ratio of record highs to record lows â $» points to a continuing, and quite possibly accelerating, rise in global temperatures.

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.

These records provide both a direct measure of sea level and an indirect measure of global ice volume.
