Sentences with phrase «natural sea ice record»

A natural sea ice record would not ever stun a scientist who understood the natural cycles.

Not exact matches

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.

But from an email conversation with Francis, Vavrus, and several other atmospheric scientists this week, it became clear that there may be more questions than answers at this point, given the large amount of natural variability that affects winter weather patterns, and the very short observational record of how the atmosphere responded to extreme losses of sea ice (only five winters of records since 2007).

Last summer's record loss of ice was due to a combination of natural cycle and global warming factors: «more greenhouse gases, an unusual wind pattern, and warming of the ocean water in regions with reduced sea ice.»

Indeed, the record - breaking losses in the past couple of years could easily be due to natural fluctuations in the weather, with summer sea ice increasing again over the next few years.

Polyak et al. (2010) looked at Arctic sea ice changes throughout geologic history and noted that the current rate of loss appears to be more rapid than natural variability can account for in the historical record.

I would have thought that was a more reasonable view than a large coincidental natural fluctuation that somehow also more rapidly warmed the land, removed Arctic sea ice and raised ocean heat content while giving us the warmest decade on record.

Page 2 of 23 Duncan Steel: Perihelion precession, polar ice and global warming Introduction Record melting of Arctic sea ice over the past year (Schiermeier 2012) has been widely presumed to be a consequence of anthropogenic global warming (AGW), and yet a natural mechanism exists that may be responsible, at least in part.

But from an email conversation with Francis, Vavrus, and several other atmospheric scientists this week, it became clear that there may be more questions than answers at this point, given the large amount of natural variability that affects winter weather patterns, and the very short observational record of how the atmosphere responded to extreme losses of sea ice (only five winters of records since 2007).
