North Atlantic Ocean currents are closest to a tipping point in a thousand years

posted in: Uncategorized | 0

A new reconstructed index of sea surface temperatures confirms previous research: The North Atlantic ocean currents appear to be approaching a point of no return, where their strength will inevitably weaken in the coming decades and centuries. Researchers confirm find that the Atlantic Meridional Overturning … Continued

Climate tipping might be predicted using algebraic topology

Theoretical progress in climate science indicates algebraic topology applied to reduced climate models might help predict if and when the Earth system will tip The Earth’s climate system seems to have shifted abruptly between colder and warmer modes in the … Continued

Steady now: Unfortunate timing and rate of change may be enough to tip a climate system

posted in: Uncategorized | 0

Unpredictable, abrupt changes to the Earth’s system of ocean currents could commence from rate-induced tipping, model study shows. ”The findings point to fundamental limitations in climate predictability,” authors warn. Imagine abrupt shifts of the tropical monsoons, reductions in Northern Hemisphere … Continued

Statistical mechanics is great improvement to complex climate models

The large uncertainties of climate models used in the IPCC reports might be reduced considerably by the use of statistical mechanics, TiPES study shows. A major challenge in climate prediction is the uncertainty on how we are going to deal … Continued
