Cool animation from @PDLRitchie! Shows the probability of triggering a climate tipping point does not go from zero to one as soon as a threshold is crossed. Instead, it depends sensitively on the time for which a threshold is exceeded. Shorter duration overshoots are safer.
New preprint out today highlighting that the duration of a 1.5C overshoot matters. We find that all climate tipping points would be avoided if global warming over 1.5C is restricted to 30 years and peak warming kept below 2.5C. doi.org/10.5194/egusphere-20… @coxypm @UofE_Research

On many parts of the land surface, the hottest days are warming faster than the annual mean, according to a new paper by Chris Huntingford, @Lambda_Joe, @PDLRitchie et al. (@UKCEHPapers @GSI_Exeter @ExeterUniMaths ). Full paper available at: rdcu.be/dDIsn

Fantastic to see Peter Ashwin from @ExeterUniMaths on this list, well deserved. Congratulations to Peter and the entire class of SIAM Fellows 2024! sinews.siam.org/Details-Page…

#Climate system #tippingpoints will be increasingly at risk under a temperature #overshoot but could social tipping points be part of the solution?

First conference, first poster and today I won a prize for it! A very supportive environment to share ideas about my research with PhD students, early career researchers and profs. Roll on another week of seminars, intro to Julia, and the half marathon! #nadcom23 @mpi_pks – at Dresden, Germany

New research from Dr Hassan Alkhayuon of
@UCCsms, Prof Sebastian Wieczorek of @eriucc
@UCCsms, @PDLRitchie of @GSI_Exeter has found that our ability to adapt to global warming will be impaired if the rate of change is too rapid

A new #TippingPoints study highlights the dangers of "rate-induced tipping" - triggered not by the level of change but by how quickly that level is reached

👏👏Huge congrats to @UniofExeter collaborators @PDLRitchie , @coxypm & @UCCsms colleagues @hassanalkhayuon and Sebastian Wieczorek for recently published article in journal @EGU_ESD which shows tipping points can be triggered earlier than expected.
@UofE_Research @UCCResearch
Excited to see our paper on rate-induced tipping published in @EGU_ESD today! The rate of change (not just magnitude) in external forcing conditions is a key mechanism for tipping in natural & human systems esd.copernicus.org/articles/… @hassanalkhayuon @coxypm @UofE_Research @UCCsms

Climate tipping points are typically viewed as ones that are triggered when a threshold is crossed (e.g. in global mean temperature). A new paper by @PDLRitchie et al. @GSI_Exeter explains the much less well-known phenomenon of rate-induced tipping esd.copernicus.org/articles/…

My poster is up in Hall X4.69 at #EGU23 ! Drop by to chat to me about #tippingpoints in the AMOC and my work on variability in the Atlantic Ocean. @EGU_Climate @EGU_NP @ExeterUniMaths
I will be at the poster today from 16:15-18:00

If you're interesting in how Early Warning Signals for tipping points might go wrong and what we can do to fix them have a read of my new paper doi.org/10.1088/1748-9326/ac…
