Sentences with phrase «accelerated albedo feedback»

Virtually ice - free summers in the arctic sea could well arrive by 2030, with troubling implications for accelerated albedo feedback and possibly disruptive changes in the jet stream.

Not exact matches

In addition to direct MYI melt due to high - latitude warming, the impact of enhanced upper - ocean solar heating through numerous leads in decaying Arctic ice cover and consequent ice bottom melting has resulted in an accelerated rate of sea - ice retreat via a positive ice - albedo feedback mechanism.

Given that this is only one of the seven major interactive feedbacks, and that it is evidently accelerating apace, I'm forced to the unwelcome conclusion that both Carbon Recovery and Albedo Restoration modes of geoengineering are now inevitably required alongside stringent Emissions Control in a Troika mitigation strategy.

As I have pointed out in the «essay», what has happened (in an accelerating manner since 1246 CE) is that the insolation reaching far northern latitudes has increased during the first half of each year, and this should be anticipated to cause earlier and more - extensive spring melting of snow and ice, and therefore a progressively - earlier albedo reduction, and therefore more sunlight subsequently being absorbed across spring and summer: the ice albedo feedback effect acting positively (causing warming).

Given that we must be near or past that point, with current albedo loss plus at least five other mega-feedbacks now accelerating, the nuanced definition of «tipping point» being that at which we are committed to the feedbacks swamping the sinks in the future, now appears redundant.

These runs are examined for evidence of accelerated climate change associated with the removal of sea ice, particularly due to increasing surface albedo feedback.
